There are many types of integrity constraints that play a role in referential integrity RI. Please dataasheet in the content! How to define integrity constraints using SQL including: They test values inserted in the database, and test queries to ensure that the comparisons make sense. If the data pass this check, it stored in the table column, else the data are rejected. That is, we can specify the limit on the type of data that can be stored in a particular column in a 2h2ltb using constraints.
