Hi,
I'm trying to determine the best way to find data in a field. Either RPG
or SQL. First some background. We have a field called Federal ID number
that contains multiple types of numbers. There is an associated field
called Federal ID type which identifies what kind of ID number it is. The
possible values are Canadian SIN (999-999-999), Employer ID (99-9999999),
SSN (999-99-9999) and Medicare # which has the same format as SSN. The
Federal ID number field is alphanumeric and it contains the dashes. We
have a logical file defined with Federal ID number as the key.
Now my question. Given a 9 digit number what is the best/fastest way to
find the record that matches? One option is to use RPG and format the
number 3 different ways and chain to the file 3 times. Would SQL provide
a better solution performance wise? I guess another option would be to
store the Federal ID number without the dashes in a seperate field. I'm
trying to avoid that if possible. TIA
