Add BEFORE and/or AFTER clause to ALTER TABLE

For the ALTER TABLE statement, it's relevant to add an "AFTER ..." OR "BEFORE ..." clause specifying where in the table the new column is to be placed. This statement component exists in DB2 for i and in certain other databases (like Informix and MySQL).

    This is mis-classified as "Informix", but it is a request for DB2 LUW!

    ALTER TABLE ... ADD newcol ... BEFORE colname

    This has been supported in Informix since the first versions that I can remember. AFTER is not needed at all except for syntax compatibility.
