Dropping a Unique Constraint

Drop a unique table constraint to remove an existing uniqueness requirement on non-null values in specified table columns.

Prerequisites 

Before you can drop a unique constraint, be sure the data server on which you are dropping a unique constraint for a table is running, and you created and established a connection to the data server.

  1. Expand the Tables folder and then expand the table that contains the unique constraint.
  2. Expand the Unique Constraints folder, and find the unique constraint you want to drop.
  3. Right-click the unique constraint, and choose Drop.
