Create temp table in SQLite if another table exists

Question

I need to create a temp table (which is a copy of Employees table) in a SQLite database, provided the table by the name of \'Employees\' exists. There are only 2 columns in Empl

Answer 1

SQLite has almost no control logic; as an embedded database, it is designed to be used together with a 'real' programming language.

You could just try to copy the data, and ignore the errors:

try:
    c.execute("CREATE TEMP TABLE tempEmployees AS SELECT * FROM Employees")
except:
    pass

However, this would also suppress any other errors.

A better idea is to check explicitly whether the table exists:

c.execute("SELECT 1 FROM sqlite_master WHERE type='table' AND name='Employees'")
if c.fetchone():
    c.execute("CREATE TEMP TABLE tempEmployees AS SELECT * FROM Employees")
