Plsql procedure for updating salary which is greater than 10000

One of the key goals when building applications is to make sure the data you enter into the database meets all your business rules.Data validation is a critical part of your application to ensure your data meets the requirements developed by your business analysts.For instance, say I want to ensure that when I enter an “ Hourly” Salary Type, I want the Salary to be less than 0.00 or when “ Monthly” Salary Type is entered the Salary is not over ,000, and when an “ Annual” Salary Type is enter then any Salary amount is fine.To implement this constraint I could use the following ADD CONSTRAINT clause: Here I have used multiple column conditions together and separated them with an “or” condition so my check constraint could validate the Salary amount for each of the different Salary Type’s.

You don’t have to create constraints that only check the values of a single column.Note this CHECK clause will cause SQL Server to generate a check constraint name because I didn’t give this constraint a name.Sometimes after you have designed and created a table, you want to place a check constraint on a table.As an example say I only have my CK_Paryroll_Salary Type check constraint on my payroll Table. It fails because the Salary Type has been typed wrong, and is not “ Hourly”, “ Monthly”, or “ Annual”. Clearly, “ NULL” is not in the valid list of Salary Types.Just to refresh your memory here is that check constraint: What do you think will happen? The reason the second INSERT statement worked is that the CK_Payroll_Salary Type constraint did not equate to FALSE when the second INSERT statement was run.
