Description
Specifies record-level constraints that must be met when editing the data.
Datasnap.DBClient.TClientDataSet.Constraints inherits from Data.DB.TDataSet.Constraints. All content below this line refers to Data.DB.TDataSet.Constraints.
Specifies record-level constraints that must be met when editing the data.
Use Constraints to read or add record-level constraints to the dataset. Record-level constraints usually impose relationships between the fields in a single record. Constraints that limit the value of a single field should be added to the individual field components.
