| Hey Guys..Is there any way to reset the identity key to 1 without using DBCC CHECKIDENT? I have a temp table which I use twice by deleting the data from it..so after deleting it for the first time and again reloading it, the identity column gives me weird values..and I am not allowed to use DBCC CHECKIDENT coz of the company rules..so is there any other way to reset it? |

| A truncate will reset the identity but you will need to be the owner.Why do you want to reset to 1 anyway - you can just subtract the minimum - only problem is you would eventually run out of IDs, that would be the dba's problem to do a manual reset. Maybe then they would allow you to automate it using checkident.==========================================Cursors are useful if you don't know sql.SSIS can be used in a similar way.Beer is not cold and it isn't fizzy. |

| Other options are to drop and recreate the tablechange the column to not be an identity, insert into a temp table to allocate the identity then into this table not have a column at all and use row_number() to allocate a value when accessedUse a trigger to allocate the value.Use an view to subtract the min identity value and add 1 so the calculated value always starts from 1.==========================================Cursors are useful if you don't know sql.SSIS can be used in a similar way.Beer is not cold and it isn't fizzy. |

| Since it's a temp table, and you're deleting, I'll say go with Nigel's 1st suggestion -- truncate |
