sql - Error when executing a stored Procedure -

-

i trying execute stored procedure failing while inserting data 1 table table. error

cannot insert duplicate key row in object 'extpndpart1' unique index 'idx_primary'

i know error comes when destination table has primary key on particular column , source table has duplicates in column. hv condition drops primary key in stored procedure.

if exists (select * dbo.sysindexes name  =  n'pk_extpndpart1' )  alter table [dbo].[extpndpart1] drop [pk_extpndpart1]

can 1 me??

seems you're looking for/dropping wrong index. you're dropping pk_extpndpart1 error refers idx_primary.
