Sybase SQL Error Message
Primary key for table ‘%1’ is not unique: Primary key value (‘%2’)
Reason for this Error
You attempted to add a new row to a table, but the new row has the same primary key as an existing row. The database has not added the incorrect row to the database. For example, you might have added a student with student number 86004 and there is already a row for a student with that number.
