I have a one more question about T-SQL
I´d like to DROP a PRIMARY KEY in database [COST_mesta_test].[dbo].['1965$'] ,table '1965$'
I have primary key on column obec (it´s varchar column) and this doesn´t work
ALTER TABLE [COST_mesta_test].[dbo].['1965$']
DROP CONSTRAINT obec
It´s give me an error
‘obec’ is not a constraint. Msg 3727, Level 16, State 0, Line 1 Could
not drop constraint. See previous errors.
Really don´t know why, because ‘obec’ is really PK.
Thanks a lot for help!
The name of your primary key isn’t likely to be the name of the constraint.
You can use
exec [COST_mesta_test]..sp_help '1965$'to find the name of the constraint (it will be in the last line of the results).
