Question

我无法在Oracle中运行此查询，因为它不允许在IN子句中使用多个列名。

CURSOR temp_3((VOUCHER_NO IN NUMBER) IS 
           SELECT * 
           FROM INVOICE_ITEM_TAB 
           WHERE INVOICE_ID, PO_REF_NUMBER IN (
              SELECT INVOICE_ID, PO_REF_NUMBER, 
              FROM INVOICE_TAB 
              WHERE VOUCHER_NO_REF IN (
                 SELECT VER_NO 
                 FROM WORK_ORDER_CODING_TAB 
                 WHERE VER_NO=VOUCHER_NO
              )
            )

有人可以帮助我

Answer 1

改为使用exists。

   SELECT * 
   FROM INVOICE_ITEM_TAB iit
   WHERE exists
      SELECT null, 
      FROM INVOICE_TAB it
      WHERE 
         iit.INVOICE_ID = it.INVOICE_ID and
         iit.PO_REF_NUMBER = it.PO_REF_NUMBER and
         it.VOUCHER_NO_REF IN (
            SELECT VER_NO 
            FROM WORK_ORDER_CODING_TAB 
            WHERE VER_NO=VOUCHER_NO
      )
    )
