Employee; GO USE Adventure Works2012; GO CREATE PROCEDURE Human Resources.For more information about INSTEAD OF triggers, see The FROM clause cannot be specified in an UPDATE statement that references, either directly or indirectly, a view that has an INSTEAD OF trigger defined on it. Update_Vacation Hours @New Hours smallint AS SET NOCOUNT ON; UPDATE Human Resources.

When a common table expression (CTE) is the target of an UPDATE statement, all references to the CTE in the statement must match. Update_Vacation Hours 40; USE Adventure Works2012; GO BEGIN TRANSACTION; BEGIN TRY -- Intentionally generate a constraint violation error. The OUTPUT clause is not supported in any DML statements that target remote tables or views. 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. Table2 (Col A int PRIMARY KEY NOT NULL, Col B decimal(10,3) NOT NULL); GO INSERT INTO dbo. When a FILESTREAM field is set to NULL, the BLOB data associated with the field is deleted.

SELECT Emp ID, New Vacation Hours, Modified Date FROM @My Table Var ORDER BY Emp ID; GO USE Adventure Works2012; GO UPDATE Sales. In the situation in which more than one sale for a specified salesperson can occur on the same day, all the sales for each sales person must be aggregated together within the USE Adventure Works2012; GO UPDATE Sales.
