Jonathan,

Do you receive an error? Depending on how the table is created, I cannot drop the
table if there are rows in it.

Regards,
Daniel Fink

Example:
SQL > create global temporary table gtt_1 (gtt_col number);

Table created.

SQL > desc gtt_1
Name Null? Type

-- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ----- -- -----
-- ---- ---- ------
GTT_COL
NUMBER

SQL > drop table gtt_1;

Table dropped.

SQL > desc gtt_1
ERROR:
ORA-04043 (See ORA-04043.ora-code.com): object gtt_1 does not exist


SQL > create global temporary table gtt_1 (gtt_col number);

Table created.

SQL > insert into gtt_1 values (1);

1 row created.

SQL > select * from gtt_1;

GTT_COL
-- ---- --
1

SQL > drop table gtt_1;

Table dropped.

SQL > desc gtt_1;
ERROR:

SQL > create global temporary table gtt_1 (gtt_col number) on commit preserve rows;

Table created.

SQL > insert into gtt_1 values (1);

1 row created.

SQL > select * from gtt_1;

GTT_COL
-- ---- --
1

SQL > commit;

Commit complete.

SQL > select * from gtt_1;

GTT_COL
-- ---- --
1

SQL > drop table gtt_1;
drop table gtt_1
*
