You're programming a Java application that uses JDBC. You need to specify the data type for a column coming back from the database and you need to supply the integer code for this column's data type. So you search online and cannot find them. You search in Sun's reference and all that you find is a dumb entry saying "these are based on the XOPEN data type codes". Brilliant, NOT!
