问题
I am experiencing an SQLite error when attempting to step on an sqlite3_stmt. Surprisingly, I got the error 14: unable to open database file.
This is confusing as I opened the database earlier, and successfully submitted an insert into one of the tables. At no point did I close the database.
BEGIN TRANSACTION
INSERT to table A
INSERT to table B
END TRANSACTION
When I attempt to run the second insert command, I get the failure.
Does anyone have any idea of what might cause this issue?
回答1:
It's likely SQLite is unable create/write to a required temporary file for the transaction. Check your temp location.
See sqlite3_temp_directory.
