Re: %CHECK and SQL

Does anyone know if there is a function in SQL like the RPG %CHECK
function where I can tell SQL to show me a list of rows where the contents
of a column does not contain a specific list of characters?

I am trying to use SQL to tell me the existing characters in a column, so
I can add logic to an RPG update program to create an error condition to
the user when they enter a character in the column that is not one of the
predefined allowed values. This is a CHAR(5) field

Perhaps REGEXP_LIKE()?

select * from myfile where not regexp_like(column_to_search, valid_ characters)
