Generating a Constraint Business Rule

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
