Teradata Alter Table Add Constraint
The RazorSQL alter table tool includes an Add Constraint option for adding check constraints to Teradata database tables. The add constraint function allows the user to add a constraint name and a constraint condition. The tool then generates the appropriate alter table SQL command for adding the constraint to the table.
Listed below is an example of the SQL generated by the Teradata Alter Table Add Constraint function:
ALTER TABLE RETAIL.EMPLOYEE
ADD CONSTRAINT test_const
CHECK (salary > 0)
Below is a screen shot of the add constraint function of the Teradata alter table tool.
