Field validation
Posted: 2016-07-18 15:38
Hello to all
I need to validate the values entered before executing the sql statements and bring up a warning message, what solutions can I take?
Examples:
check that the period of two data fields does not exceed one month;
check that the field 2 is not empty if the field has a value of 1;
thank you
