使用PostgreSQL从单个查询中的两个不同表中删除

Question

DELETE amt
FROM $citables.CI_INBOUND_INVOICE_AMT amt
   , $citemp.invoice_combine ic
WHERE amt.ci_inb_inv_id = ic.TSR_EDI_INV_REF;

这是Teradata代码，需要转换为PostgreSQL。我收到错误消息

ERROR:  syntax error at or near "amt"

LINE 1: DELETE amt

即使内部联接也不起作用。

Answer 1

也许您可以尝试：

DELETE 
FROM $citables.CI_INBOUND_INVOICE_AMT amt
WHERE EXISTS (
    SELECT 1 
    FROM $citemp.invoice_combine ic 
    WHERE amt.ci_inb_inv_id = ic.TSR_EDI_INV_REF
);
