How to reset the sequence for IDs on PostgreSQL tables如何從Python程序
我知道,我可以從terminal
復位,但我想它從Django的Python程序復位設置主鍵序列。我現在試圖使用RAW
sql
postgres=# \c uihspot
You are now connected to database "uihspot" as user "postgres".
uihspot=# \dt

但我找不到表!
你打算如何使用它?在遷移? –
我的目標是解決通過Django引發的Postgres「數據庫處於恢復模式」。我已經在'/ var/log/postgres'中檢查了日誌文件。當我使用'bulk_create'時會引發。那麼我想這可能是'id'溢出的問題。然後我試圖從python中重置'sequence_id',而不是從終端重置。我上傳1輪會使〜id增加'id' – Sarit
不,你在這兒吠叫錯了樹。該錯誤消息明確表示,您只需要再次嘗試查詢(在您的其他問題中)。但正如我在答案中提到的,通過django objects.bulk_create simple加載數據不是正確的方法。 – e4c5
