Hello Sir/Madam
Is there any method to check if the same value is already taken in the Data base. I mean suppose a person have taken leave from 12-09-23 to 25-09-23.
(two Date fields). If some body tries to enter the value for leave from 13-09-23 to 14-09-23 for the same person, it should flash error mesage. is it possible.
