ORA-01652: unable to extend temp segment by 128 in tablespace XXXXX

Hi

Need some help please.

I am trying to create a table using the "create table as" syntax using unions on a couple of tables.

However when I create the table I get the following error message:

ORA-01652: unable to extend temp segment by 128 in tablespace XXXXX

The tablespace has more than enough space available (To be exact, it had 12GB and increase it to 13GB) and still errors.

When checking the size of the tables I'm doing the union on, they are +/- 2GB in total.

Anyone have an explanation for me as to why I the database requires me to increase the size of the tablespace when there is more than enough space available?
