由 家住魔仙堡 提交于 2020-05-11 07:22:34

MySQL rows delete when program exits

由 随声附和 提交于 2020-02-15 10:39:30
问题 I'm using Python and MySQLdb to add rows to my database. It seems that when my script exits, the rows get deleted. My last lines before the script exits do a "select *" on the table, which shows my one row. When I re-run the script, the first lines (after opening the connection) do the same "select *" and return zero results. I'm really at a loss here. I've been working for about 2 hours on this, and can't understand what could be accessing my database. Also, between running the scripts, I
