Hello, I am seeing an interesting performance issue with INSERT statements. I am using Sqlite 3.3.5 on a Windows XP box. Here is a brief summary of the situation:
Insert statements that require no join are quite fast: a) I create an empty table (drop it first if it exists). b) INSERT ... SELECT ... FROM another-table WHERE ... But, if the Insert statement requires a join, the performance degrades drastically: a) I create an empty table (drop it first if it exists). b) INSERT ... SELECT ... FROM table-1 JOIN table-2 WHERE ... Even when the two joined tables have 10,000 records each and those records match one to one, the query goes from taking a second or so in the first case to over 30-40 minutes in the second case. The processing is CPU intensive and pretty much locks down the PC during this process. Is this a common experience or do I need to play around with the configuration options? ____________________________________________________________________________________ Want to start your own business?
