For more information, see @@ROWCOUNT (Transact-SQL). Variable names can be used in UPDATE statements to show the old and new values affected, but this should be used only when the UPDATE statement affects a single record. The Microsoft SQL Server ODBC driver and OLE DB Provider for SQL Server automatically set ANSI_PADDING ON for each connection.

If the UPDATE statement affects multiple records, to return the old and new values for each record, use the OUTPUT clause. This can be configured in ODBC data sources or by setting connection attributes or properties.

For more information about predicates and search conditions, see Search Condition (Transact-SQL). Table2; USE Adventure Works2012; GO IF OBJECT_ID ('dbo.

CURRENT OF Specifies that the update is performed at the current position of the specified cursor. Table1', ' U') IS NOT NULL DROP TABLE dbo. Table2', ' U') IS NOT NULL DROP TABLE dbo. Table1 (c1 int PRIMARY KEY NOT NULL, c2 int NOT NULL); GO CREATE TABLE dbo. Table2 WHERE CURRENT OF abc; GO SELECT c1, c2 FROM dbo.

Compound assignment operator: = Add and assign -= Subtract and assign *= Multiply and assign /= Divide and assign %= Modulo and assign &= Bitwise AND and assign ^= Bitwise XOR and assign |= Bitwise OR and assign Returns updated data or expressions based on it as part of the UPDATE operation.

The OUTPUT clause is not supported in any DML statements that target remote tables or views.

Common table expressions can also be used with the SELECT, INSERT, DELETE, and CREATE VIEW statements.

A view with an INSTEAD OF UPDATE trigger cannot be a target of an UPDATE with a FROM clause.

Note Any call to OPENDATASOURCE, OPENQUERY, or OPENROWSET in the FROM clause is evaluated separately and independently from any call to these functions used as the target of the update, even if identical arguments are supplied to the two calls.

For more information, see WITH common_table_expression (Transact-SQL). For information about table hints, see Table Hints (Transact-SQL).

TOP ( ) Specifies one or more table hints that are allowed for a target table. @Note When referencing the Unicode character data types nchar, nvarchar, and ntext, 'expression' should be prefixed with the capital letter ' N'.
