Hi,

if am not wrong "SID" is your column name which you are trying to delete by using PRIMARY Key keyword. so, that is not possible. you may have to drop the primary associated with table just specifying the primary key keyword, or specifying the primary key constraint name.

refer the article SQL SERVER How to Drop Primary Key Contraint[^] for various ways of droping the constraints.

hope it helps.
