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.

A positioned update using a WHERE CURRENT OF clause updates the single row at the current position of the cursor. Table2 (d1 int PRIMARY KEY NOT NULL, d2 int NOT NULL); GO INSERT INTO dbo. Table2 VALUES (1, 20), (2, 30); GO DECLARE abc CURSOR LOCAL FOR SELECT c1, c2 FROM dbo.

To replace or modify large blocks of text, ntext, or image data, use WRITETEXT or UPDATETEXT instead of the UPDATE statement.This can be more accurate than a searched update that uses a WHERE ] ) Specifies that optimizer hints are used to customize the way the Database Engine processes the statement. Avoid using these hints in this context in new development work, and plan to modify applications that currently use them.For more information, see Query Hints (Transact-SQL). All char and nchar columns are right-padded to the defined length.Table1 VALUES(1, 10.0), (1, 20.0); INSERT INTO dbo. Avoid using these data types in new development work, and plan to modify applications that currently use them.
