Re: [sqlite] sqlite_sequence table
See my previous e-mail: I was querying temp.sqlite_sequence when I thought I was querying main.sqlite_sequence.

Re: [sqlite] sqlite_sequence table
Aha! I've got AUTOINCREMENT keys in both regular and temporary tables. This results in two sqlite_sequence tables, one in sqlite_master and one in sqlite_temp_master. And evidently, if I have a permanent and a temporary table with the same name, a query that doesn't specify gets the temporary table. If I do "SELECT * FROM main.sqlite_sequence" I see what I'm looking for. Will On 11/16/10 1:31 PM, "Will Duquette" wrote: Yes.

Re: [sqlite] sqlite_sequence table
Yes. I've done a couple of inserts into the table, interspersed with queries to the sqlite_sequence table; they show the sqlite_sequence table as being empty.
