Question

I have a table called tbl_loans which has the field loan_number.

Loan numbers are like 0001, 0023, 0045 so I want to find out whether there is loan number length is lower than 4 numbers or greater than 4 numbers

Is there easy way to find out this?

Answer 1

SELECT * FROM tbl_loans WHERE LENGTH(loan_number)<>4;
