Hello readers. One of the major problem with primary key when set to auto increment is, when a row is deleted from the table the value of the primary key of that row is lost. So here is a small Trigger script for the table that will keep the primary key always in sequence that means this trigger always maintain the order or primary key like 1,2,3,4... We need two triggers to make it possible. One check the value of primary key at time of Insert and other checks at Deletion. First create a table  CREATE TABLE AITEST ( TBLID  INT IDENTITY ( 1 , 1 ) PRIMARY KEY ,   TBLNAME  NVARCHAR ( 50 )) Trigger One CREATE TRIGGER [dbo] . [CHKSETIDENT] ON [dbo] . [AITEST] AFTER INSERT AS DECLARE @CURIDENT INT = ( SELECT IDENT_CURRENT ( 'AITEST' )) DECLARE @LASTROW INT = ( SELECT COUNT (*) FROM AITEST ) IF @CURIDENT < @LASTROW       BEGIN             DBCC CHECKIDENT ( 'AITEST' , RESEED , @LASTROW )             SELECT * FROM AITEST       END ELSE

Hello readers, Below is the query to inset multiple values in a Table name items in a single INSERT statement.
