Question

我想将tableA中记录的所有记录与value3 = True一起插入tableB。然后我想在tableA中删除这些记录。我想在一个语句中执行此操作并尝试运行以下SQL语句

DELETE FROM
  TableA
WHERE
  rowID IN (INSERT INTO TableB (Value1, Value2)
        SELECT Value1, Value2 FROM TableA WHERE Value3=TRUE RETURNING rowID)

但它不起作用。如何修复此SQL以使其按计划运行？

Answer 1

为什么不分成两个命令？

insert into TableB
select * from TableA where value3 = True

delete from TableA
where rowID in (select * from TableA where value3 = True)

从插入到语句中删除
