sql server 2005 : i have a column empid in employee table with identity on.if there is some error while inserting data into table .identity is incremented .i want identity to be incremented only if record is inserted .like if i have generated emp id from 1 to 5 and then on 6th record insertion error ocurrs.and on next record insertion identity value will be 7 .i want it to be 6.
Why do you want to do that ?
The identity column should only be used as an ‘internal administrative value’ for the database, and it should have no ‘business value’, so why does it matter that there are gaps in that sequence ?
If identity is used correctly, then users of your software will never be faced with the column that has an identity value; you just use it to uniquely identify a record.
