hi Markus,
I just tried for fun:
start = time.time()
SQLString=('''SELECT * FROM entry, word, word_entry WHERE
entry.id = word_entry.entry_id AND
word.id = word_entry.word_id AND
word.word GLOB '%s'
''' % "hui*")
c.execute(SQLString)
and it is as fast as your first one - seems a pysqlite problem to me
I know they say this is not a secure way to do it -- well.
Kind regards,
W.Braun

Hi,
when using bind variables I get a huge performace drop compared to
using a plain string. The query is demonstrated in the attached file
"problematic_query.py".
The database used can be downloaded from
http://xile.org/le/prepared_statement.zip (1.75 MB)
or generated by using the attached file "create_test_db.py".
Kind regards,
Markus
