Abstract
Constraint enforcement identifies rows containing a value violating a constraint. A SQL DELETE statement is generated for each row violating the constraint utilizing an index value associated with each row. Initialization of a CHECK utility performing constraint enforcement includes identifying an index defined for the table to be checked as well as the column name for the index value to facilitate generation of the SQL DELETE statements using the index column name and value. Generating the SQL delete statement utilizing an index value associated with each row in the database table rather than by utilizing the value causing the constraint violation eliminates the need to read the entire database table to execute the DELETE statement.
