If this value is not specified, the system generates a name for the constraint. Enables system versioning of the table if the datatype, nullability constraint, and primary key constraint requirements are met. The system will record the history of each record in the system-versioned table in a separate history table.

If the name of a history table is specified during history table creation, you must specify the schema and table name. If the history table does not exists, the system generates a new history table matching the schema of the current table in the same filegroup as the current table, creating a link between the two tables and enables the system to record the history of each record in the current table in the history table.

By default, the history table is PAGE compressed. If current table is partitioned, the history table is created on default file group because partitioning configuration is not replicated automatically from the current table to the history table. When creating a link to an existing history table, you can choose to perform a data consistency check. This data consistency check ensures that existing records do not overlap.

Performing the data consistency check is the default. Using existing history tables with ledger tables is not allowed. Creates the new table with Stretch Database enabled or disabled. For more info, see Stretch Database. Avoid using this feature in new development work, and plan to modify applications that currently use this feature. For more info about enabling Stretch for a table, see Enable Stretch Database for a table. Before you enable Stretch for a table, you have to enable Stretch on the server and on the database.

For more info, see Enable Stretch Database for a database. Optionally specifies a filter predicate to select rows to migrate from a table that contains both historical and current data. The predicate must call a deterministic inline table-valued function. For more info, see Enable Stretch Database for a table and Select rows to migrate by using a filter function.

If you provide a filter predicate that performs poorly, data migration also performs poorly. For more info, see Disable Stretch Database and bring back remote data. For more info, see Pause and resume data migration -Stretch Database. Enables retention policy based cleanup of old or aged data from tables within a database. For more information see Enable and Disable Data Retention.

The following parameters must be specified for data retention to be enabled. The following data types are allowed for the filter column. The retention period is specified as a combination of an positive integer value and the date part unit. The value ON indicates that the table is memory optimized. Memory-optimized tables are part of the In-Memory OLTP feature, which is used to optimize the performance of transaction processing. For more in-depth information about memory-optimized tables see Memory-Optimized Tables.

The table schema is persisted but any data updates are not persisted upon a restart or failover of the database.

Indicates the number of buckets that should be created in the hash index. For more information about bucket counts, see Indexes for Memory-Optimized Tables.

For details about adding and removing indexes on memory-optimized tables, see Altering Memory-Optimized Tables. Otherwise, the system creates an updatable ledger table. An updatable ledger table must also be a system-versioned table. An append-only ledger table must contain exactly one column defined with each of the following arguments:. If there is a name conflict with an already defined column, the system will raise an error.

If a view with the specified or generated name exists, the system will raise an error. If the table is an updatable ledger table, the ledger view is created as a union on the table and its history table. Each row in the ledger view represents either the creation or deletion of a row version in the ledger table.

The ledger view contains all columns of the ledger table, except the generated always columns listed above. The ledger view also contains the following additional columns:. Transactions that include creating ledger table are captured in sys. Each of the ledger view option specifies a name of a column, the system will add to the view, in addition to the columns defined in the ledger table. For information about the number of allowed tables, columns, constraints and indexes, see Maximum Capacity Specifications for SQL Server.

Space is generally allocated to tables and indexes in increments of one extent at a time. After it has enough pages to fill a uniform extent, another extent is allocated every time the currently allocated extents become full.

You can create local and global temporary tables. Local temporary tables are visible only in the current session, and global temporary tables are visible to all sessions. Temporary tables cannot be partitioned.

If more than one temporary table is created inside a single stored procedure or batch, they must have different names. All temporary tables are created in the dbo schema. If a local temporary table is created in a stored procedure or application that can be executed at the same time by several sessions, the Database Engine must be able to distinguish the tables created by the different sessions. The Database Engine does this by internally appending a numeric suffix to each local temporary table name.

The full name of a temporary table as stored in the sys. A local temporary table created within a stored procedure or trigger can have the same name as a temporary table that was created before the stored procedure or trigger is called. However, if a query references a temporary table and two temporary tables with the same name exist at that time, it is not defined which table the query is resolved against.

Nested stored procedures can also create temporary tables with the same name as a temporary table that was created by the stored procedure that called it. However, for modifications to resolve to the table that was created in the nested procedure, the table must have the same structure, with the same column names, as the table created in the calling procedure. This is shown in the following example.

If a temporary table is created with a named constraint and the temporary table is created within the scope of a user-defined transaction, only one user at a time can execute the statement that creates the temp table. For example, if a stored procedure creates a temporary table with a named primary key constraint, the stored procedure cannot be executed simultaneously by multiple users.

Global temporary tables for SQL Server initiated with table name are stored in tempdb and shared among all users’ sessions across the whole SQL Server instance.

Azure SQL Database supports global temporary tables that are also stored in tempdb and scoped to the database level. This means that global temporary tables are shared for all users’ sessions within the same Azure SQL Database. User sessions from other databases cannot access global temporary tables. Similarly, global temporary stored procedures are also scoped to the database level in Azure SQL Database.

See the above section on Temporary Tables. For troubleshooting tempdb, see How to Monitor tempdb use. Any user can create global temporary objects. Users can only access their own objects, unless they receive additional permissions. Second, you must create a partition scheme to specify the filegroups that will hold the partitions indicated by the partition function.

For more information, see Partitioned Tables and Indexes. If a primary key is defined on a CLR user-defined type column, the implementation of the type must support binary ordering. Cross-database referential integrity must be implemented through triggers. This is referred to as a self-reference. This column must have the same data type as the column on which the constraint is defined.

The data type of each reference column must also be the same as the corresponding column in the column list. The reference columns must be specified in the same order that was used when specifying the columns of the primary key or unique constraint on the referenced table. The effective limit for you may be more or less depending on the application and hardware. If a foreign key is defined on a CLR user-defined type column, the implementation of the type must support binary ordering.

Columns participating in a foreign key relationship must be defined with the same length and scale. The following table shows the niladic functions and the values they return for the default during an INSERT statement. DEFAULT definitions cannot be created for columns with alias data types if the alias data type is bound to a default object. When a rule and one or more CHECK constraints exist for a column or columns, all restrictions are evaluated.

CHECK constraints cannot be defined on text , ntext , or image columns. For a report on the views and stored procedures that depend on a table, use sys. The nullability of a column determines whether that column can allow a null value NULL as the data in that column. We recommend that you always explicitly define a column as NULL or NOT NULL for noncomputed columns or, if you use a user-defined data type, that you allow the column to use the default nullability of the data type.

Sparse columns must always allow NULL. When column nullability is not explicitly specified, column nullability follows the rules shown in the following table. If the column is a computed column, its nullability is always automatically determined by the Database Engine. System tables cannot be enabled for compression. When you are creating a table, data compression is set to NONE, unless specified otherwise.

If you specify a list of partitions or a partition that is out of range, an error will be generated. For a more information about data compression, see Data Compression. Because a constraint name is not specified, the system supplies the constraint name. Foreign keys can be single-column keys or multicolumn keys. Note that the column name does not have to be the same in both tables.

Multicolumn key constraints are created as table constraints. The following example shows how to reference this key from another table; an explicit constraint name is optional. The following example enforces a restriction that the Name column of the Product table must be unique. For example, the AdventureWorks database could include a lookup table listing the different jobs employees can fill in the company.

Under a column that describes each job, a character string default could supply a description when an actual description is not entered explicitly. Use the following example to get the current date for an entry.

A niladic-function scan can also improve data integrity. To keep track of the user that inserted a row, use the niladic-function for USER. Do not enclose the niladic-functions with parentheses. The following example shows a restriction made to values that are entered into the CreditRating column of the Vendor table.

The constraint is unnamed. This example shows a named constraint with a pattern restriction on the character data entered into a column of a table. This example specifies that the values must be within a specific list or follow a specified pattern. The following example shows the complete table definitions with all constraint definitions for table PurchaseOrderDetail created in the AdventureWorks database. Note that to run the sample, the table schema is changed to dbo.

The following example creates a partition function to partition a table or index into four partitions. Then, the example creates a partition scheme that specifies the filegroups in which to hold each of the four partitions.

Finally, the example creates a table that uses the partition scheme. This example assumes the filegroups already exist in the database. Based on the values of column col1 of PartitionTable , the partitions are assigned in the following ways.

The following example creates a table with a uniqueidentifier column. The following example creates a table with one column defined as user-defined type utf8string , assuming that the type’s assembly, and the type itself, have already been created in the current database. A second column is defined based on utf8string , and uses method ToString of type class utf8string to compute a value for the column. For additional data compression examples, see Data Compression.

Applies to : SQL Server The following examples show to how to create a table that has a sparse column, and a table that has two sparse columns and a column set. The examples use the basic syntax. This example creates a table that has two sparse columns and a column set named CSet. The following examples show how to create a temporal table linked to a new history table, and how to create a temporal table linked to an existing history table.

Note that the temporal table must have a primary key defined to be enabled for the table to be enabled for system versioning. For examples showing how to add or remove system versioning on an existing table, see System Versioning in Examples. For use cases, see Temporal Tables. The following example shows how to create a system-versioned memory-optimized temporal table linked to a new disk-based history table. The following example creates a table with two encrypted columns.

For more information, see Always Encrypted. Creates a table with an anonymously named compound primary key. This is useful to avoid run-time conflicts where two session-scoped temp tables, each in a separate session, use the same name for a constraint. The problem arises from the fact that while the temp table name is unique, the constraint names are not. This select fails due to the database scope for the global temp tables.

The following example creates a table with data retention enabled and a retention period of 1 week. The following example creates an updatable ledger table that is not a temporal table with an anonymous history table the system will generate the name of the history table and the generated ledger view name. As the names of the required generated always columns and the additional columns in the ledger view are not specified, the columns will have the default names.

The following example creates a table that is both a temporal table and an updatable ledger table, with an anonymous history table with a name generated by the system , the generated ledger view name and the default names of the generated always columns and the additional ledger view columns.

The following example creates a table that is both a temporal table and an updatable ledger table with the explicitly named history table, the user-specified name of the ledger view, and the user-specified names of generated always columns and additional columns in the ledger view. The following example creates an append-only ledger table with the generated names of the ledger view and the columns in the ledger view. The following example creates a ledger database in Azure SQL Database and an updatable ledger table using the default settings.

However, Name AutoCorrect cannot repair all references to renamed objects. The buttons that you use to move through records. These buttons are located in the lower left corner of the Datasheet view and Form view. The buttons are also available in Print Preview so that you can move through the pages of your document. The pane that appears when you open an Access database or an Access project.

The Navigation Pane displays the objects in the database, and can be customized to sort and group objects in different ways. In an Access project, a fixed-length data type with a maximum of 4, Unicode characters. Unicode characters use 2 bytes per character and support all international characters. To minimize the duplication of information in a relational database through effective table design. You can use the Table Analyzer Wizard to normalize your database. Columns with the ntext data type store a byte pointer in the data row, and the data is stored separately.

A value you can enter in a field or use in expressions or queries to indicate missing or unknown data. In Visual Basic, the Null keyword indicates a Null value. Some fields, such as primary key fields, can’t contain a Null value.

A field containing a Null value. A null field is not the same as a field that contains a zero-length string ” ” or a field with a value of 0. In an Access database, a field data type designed for numerical data that will be used in mathematical calculations. Use the Currency data type, however, to display or calculate currency values. In an Access project, a variable-length data type with a maximum of 4, Unicode characters. A fundamental data type representing any object that can be recognized by Visual Basic.

Although you can declare any object variable as type Object, it is best to declare object variables according to their specific types. Shows objects that have a dependency on the selected object and also objects on which the selected object has dependencies. A file that contains definitions of objects and their methods and properties. The file that contains an object library typically has the file name extension.

A type of object exposed by a program through Automation; for example, Application, File, Range, and Sheet. Use the Object Browser in the Visual Basic Editor or refer to the program’s documentation for a complete listing of available objects.

An Access tool that you can use to connect to an SQL database when you create a pass-through query. If you save the query, the connection string is stored with the query. Data and the information needed to access that data from programs and databases that support the Open Database Connectivity ODBC protocol. A database for which an Open Database Connectivity ODBC driver — a driver that you can use for importing, linking to, or exporting data — is supplied.

A program that contains a linked or embedded OLE object from another program. A component database architecture that provides efficient network and Internet access to many types of data sources, including relational data, mail files, flat files, and spreadsheets. An object supporting the OLE protocol for object linking and embedding. A field data type that you use for objects created in other programs that can be linked or embedded inserted in an Access database.

An association between two tables in which the primary key value of each record in the primary table corresponds to the value in the matching field or fields of many records in the related table. An association between two tables in which the primary key value of each record in the primary table corresponds to the value in the matching field or fields of one, and only one, record in the related table.

A control, also called a radio button, that is typically used as part of an option group to present alternatives on a form or report. A user cannot select more than one option. A frame that can contain check boxes, toggle buttons, and option buttons on a form or report. You use an option group to present alternatives from which the user can select a single option.

A join in which each matching record from two tables is combined into one record in the query’s results, and at least one table contributes all of its records, even if the values in the joined field don’t match those in the other table. When security is being used, the user account that has control over a database or database object.

By default, the user account that created a database or database object is the owner. A portion of the database file in which record data is stored. Depending on the size of the records, a page 4 KB in size may contain more than one record. Used to display page summaries, dates, or page numbers at the bottom of every page in a form or report.

In a form, the page footer appears only when you print the form. Used to display a title, column headings, dates, or page numbers at the top of every page in a form or report. In a form, the page header appears only when you print the form. A query in which a user interactively specifies one or more criteria values. A parameter query is not a separate kind of query; rather, it extends the flexibility of a query. A database that contains only a subset of the records in a full replica.

With a partial replica, you can set filters and identify relationships that define which subset of the records in the full replica should be present in the database.

By using pass-through queries, you work directly with the tables on the server instead of the data being processed by the Access database engine. A set of attributes that specifies what kind of access a user has to data or objects in a database. An object stored in the database; for example, a database table or QueryDef object. Dynaset-type or snapshot-type Recordset objects are not considered persistent objects because they are created in memory as needed.

A case-sensitive alphanumeric string that is 4 to 20 characters long and that Access uses in combination with the account name to identify a user or group in an Access workgroup. A type of locking in which the page containing one or more records, including the record being edited, is unavailable to other users when you use the Edit method, and remains unavailable until you use the Update method.

A view that shows a graphical analysis of data in a datasheet or form. You can see different levels of detail or specify the layout by dragging fields and items or by showing and hiding items in the drop-down lists for the fields. An interactive table that summarizes large amounts of data by using format and calculation methods that you choose. You can rotate its row and column headings to view the data in different ways, similar to an Excel PivotTable report.

Data displayed in a row and column format can be moved, filtered, sorted, and calculated in ways that are meaningful for your audience. A view that summarizes and analyzes data in a datasheet or form. You can use different levels of detail or organize data by dragging the fields and items or by showing and hiding items in the drop-down lists for the fields. The pointer that appears when you move the pointer to the left edge of a field in a datasheet.

When the plus pointer appears, you can click to select the entire field. One or more fields columns whose values uniquely identify each record in a table. A primary key cannot allow Null values and must always have a unique index. A primary key is used to relate a table to foreign keys in other tables. The “one” side of two related tables in a one-to-many relationship.

A primary table should have a primary key and each record should be unique. A Sub or Function procedure is declared as private by using the Private keyword in a Declare statement. Private procedures are available for use only by other procedures within the same module.

A sequence of declarations and statements in a module that are executed as a unit. Describes any variables or constants declared within a procedure. Variables and constants declared within a procedure are available to that procedure only.

A variable that is declared within a procedure. Procedure-level variables are always private to the procedure in which they’re declared. The set of all code modules in a database, including standard modules and class modules. By default, the project has the same name as the database. A pane that is used to view or modify the properties of various objects such as tables, queries, fields, forms, reports, data access pages, and controls. A dynamic cross-reference of one or more table data fields columns that permits an ODBC table server table without a unique index to be edited.

A public variable can be shared by all the procedures in every module in a database. In an Access project, a publication can contain one or more published tables or stored procedure articles from one user database. Each user database can have one or more publications.

An article is a grouping of data replicated as a unit. To save a database to a document management server, such as a server running Windows SharePoint Services. A question about the data stored in your tables, or a request to perform an action on the data. A query can bring together data from multiple tables to serve as the source of data for a form or report.

In an Access project, an approximate numeric data type with seven-digit precision. It can hold positive values from approximately 1. A control used on a data access page to display a record navigation toolbar.
