Thank you for the explanation. And this file is always created even if I
do not use TEMP tables? Because I am not using them.
You always have an SQLITE_TEMP_MASTER table, which is also stored in the
same temporary file.

I only wonder, what is the file SQLite creates in /tmp? My program
calls "CREATE TABLE", "INSERT" and "SELECT". Why does SQLite need
some temporary file?
That temporary file is where it stores temporary tables created
using CREATE TEMP TABLE and so forth. Additional temporary files
will be created for some intermediate tables needed to evaluate
certain subqueries. For example, if you do
... WHERE x IN (SELECT a FROM table1);
The results of the subquery are stored in a separate database file
created in /tmp.
