If the object being updated is the same as the object in the FROM clause and there is only one reference to the object in the FROM clause, an object alias may or may not be specified. 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. Table1; GO Support for use of the READUNCOMMITTED and NOLOCK hints in the FROM clause that apply to the target table of an UPDATE or DELETE statement will be removed in a future version of SQL Server.If the object being updated appears more than one time in the FROM clause, one, and only one, reference to the object must not specify a table alias. Avoid using these hints in this context in new development work, and plan to modify applications that currently use them.Use caution when specifying the FROM clause to provide the criteria for the update operation.
