    Post how to make this query?

    Hello all,

    I have the following table:

    create table Sale(
    bankname char(8) null,
    controlename char(10) not null,
    creditcardnummer numeric(19) null,
    username char(10) not null,
    accountnummer numeric(7) null,
    constraint pk_username primary key(username)
    )

    I want to make a case/trigger where the following happens:
    If the word "Creditcard" has been inserted in controlename then creditnummer must contain numbers else it will be NULL.
