The second example removes multiple columns. The following example splits a partition on a table. The following three statements add a column set named CS, and then modify columns C2 and C3 to SPARSE. In other words, escalation will be allowed to the partition level. First, a table is created without any encrypted columns. These include user-defined type variables and user-defined functions. In this example, the OrdersHistory table has the following two partitions and both partitions are empty: For the previous two tables, the following command moves all rows with OrderDate < '2004-01-01' from the Orders table to the OrdersHistory table. Applies to: SQL Server (SQL Server 2017 (14.x) and later) and Azure SQL Database. FILTER_COLUMN = { column_name } Use the ALTER COLUMN clause. ALTER TABLE - ADD Column To add a column in a table, use the following syntax: To verify that the default is applied, another value is inserted into the first column, and the table is queried. By default, period columns aren't hidden. The column is added as an offline operation in this case. Specifies whether underlying tables and associated indexes are available for queries and data modification during the index operation. ALTER TABLE acquires a schema modify (SCH-M) lock on the table to make sure that no other connections reference even the metadata for the table during the change, except online index operations that require a short SCH-M lock at the end. Be sure that you always explicitly define a column as NULL or NOT NULL for noncomputed columns. You can't drop either the Department or the DepartmentHistory tables while system versioning is enabled.
ROWGUIDCOL doesn't enforce uniqueness of the values stored in the column and doesn't automatically generate values for new rows that are inserted into the table.
Used in a CHECK or UNIQUE constraint. PARTITION = ALL Specify OUTBOUND to migrate data from SQL Server to Azure. The current setting for SET ARITHABORT is ignored. The syntax to rename a table in SQL Server (Transact-SQL) is: Let's look at an example that shows how to rename a table in SQL Server using sp_rename. For more information, see Disable Stretch Database and bring back remote data. For more information, see Pause and resume data migration - Stretch Database. To enable system versioning of a table, the system verifies that the datatype, nullability constraint, and primary key constraint requirements for system versioning are met. Applies to: SQL Server (SQL Server 2016 (13.x) and later) and Azure SQL Database. If the new column allows null values and you add a default definition with the new column, you can use WITH VALUES to store the default value in the new column for each existing row in the table. The following example shows how to encrypt a column using Always Encrypted with secure enclaves. ALTER TABLE operates as if ARITHABORT is set to ON. However, you can use sp_rename, though Microsoft recommends that you drop and recreate the table so that scripts and stored procedures are not broken. The syntax to add a column in a table in SQL Server (Transact-SQL) is: Let's look at an example that shows how to add a column in an SQL Server table using the ALTER TABLE statement. The syntax to modify a column in an existing table in SQL Server (Transact-SQL) is: Let's look at an example that shows how to modify a column in a table in SQL Server using the ALTER TABLE statement.
