TCheckConstraint.CustomConstraint Property

Contains the SQL text representation of a constraint defined on a record by an application.

Pascal

property CustomConstraint: string;

C++

__property AnsiString CustomConstraint;

Description

Use CustomConstraint to store the SQL text that defines a check constraint defined by the application for a dataset component. Custom constraints are local to the application and do not get applied by the server when an application writes its changes to a database.

Note: Custom constraints are SQL expressions. Because of this, always use a period (.) as a floating-point separator. This may be inconsistent with international Windows

settings.
