But you could! With just a little effort on your part.

Take a little time, do the following:

CREATE DOMAIN D_INTEGER AS Integer;
CREATE DOMAIN D_Varchar_20 AS VARCHAR( 20);

Then when you create your temporary tables just make 2 minor changes:

create global temporary table TEMP_112233
(
id : D_Integer,
name : D_varchar_20
)
