The type of constraint generated depends on the type of DBMS.
Database type |
Generation result |
---|---|
Database does not support any check constraints |
No constraint is generated |
Database does not support multiple check constraints |
Constraint business rules, check parameters, and validation business rules are concatenated into a single constraint expression |
Database supports multiple check constraints |
First, the check parameters and validation business rules are generated into a single constraint, then the constraint business rules are generated into different constraints. Constraints are thus ordered |
