I have a sqlite (version 3.6.13) database with 300000+ rows 1500 of these rows have faulty data.
So I read the main database row by row, tested the validity of one column, and inserted the good rows into a new database. This process took 27 minutes on a fairly recent desktop computer. ( about 10000 rows a minute or 170 a second ) I thought the whole process would take a few seconds, so I wonder if 27 minutes is a reasonable time for this database creation. As the database was being created, I noticed a journal file was in use though I haven't worked out what that did, yet. TIA Owen
