Example 1 with RowSetNavigatorLinkedList

use of org.hsqldb_voltpatches.navigator.RowSetNavigatorLinkedList in project voltdb by VoltDB.

the class StatementDML method executeDeleteStatement.

// prior to actual delete operation

     * Executes a DELETE statement.  It is assumed that the argument is
     * of the correct type.
