You can create multiple temporary tables, but they must have different
names.
A TEMPORARY table can have the same name as a non-TEMPORARY table.
The non-TEMPORARY table is hidden to the client that creates the
TEMPORARY table as long as the TEMPORARY table exists.
A second TEMPORARY table with the same name cannot be created.
This is on a connection-specific basis. Two clients each can create
a TEMPORARY table with the same name. Only the table created by a given
client is visible to that client.
