i want to know whether i can delete a specfic record in sql server 2005 prior to execute the delete query.

is there any query to do so ?

Whilst the above may/does work for SQL2k5 ,
The following also works for SQL2k DB.
I had to crib this together because some of our processes are ’so generic’ they don;t know what table they’ll be passed let alone what the primary key will be (for use in DML)
SELECT SC.Name, SC.COLID
FROM SYSOBJECTS SO
INNER JOIN SYSINDEXKEYS SI ON SO.ID = SI.ID AND SI.INDID = 1
INNER JOIN SYSCOLUMNS SC ON SO.ID = SC.ID AND SC.COLID=SI.COLID
WHERE SO.NAME= @MyTableName
AND SO.XTYPE=’U’
Corrections are welcome.

Hello Shwetang,
What I read on internet, is it is not possible to create a foriegn key constraint referencing table outside database.
I tried myself creating this but had no luck…
The only solution to your problem is triggers.
or create child table in the same database as parent table.
Thanks,
Imran
Imran,
You are correct.
