You can use the posstr function to locate a character in a string, and then use the substr function to retrieve a part from a string. This could be done from an anonymous block or stored procedure. You put this in a function (UDF): set index = posstr(string, '-'); if (index <> 0) then -- Recursive case set pre = substr(string, index-1); set pos =
