2.3.23 Operands related to referential and check constraints

120) pd_constraint_name = LEADING | TRAILING
Specifies whether to specify a constraint name definition before or after constraint definition in referential constraint or check constraint.
LEADING: Specifies a constraint name definition before constraint definition (standard SQL specification).
TRAILING: Specifies a constraint name definition after constraint definition (XDM/RD-compatible specification).
121) pd_check_pending = USE | NOUSE
Specifies whether or not the check pending status (state that prevents the use of data for which integrity can no longer be guaranteed) is to be used in referential constraint or check constraint.
USE:
Use the check pending state.
NOUSE:
Do not use the check pending state.
Specification guidelines
Normally specify USE. If NOUSE is specified in this operand, data integrity may not be guaranteed. If processing performance is more important than data integrity, then specify NOUSE.
