导读：DELETE B.* FROM m_productprice B INNER JOIN m_product C ON B.m_product_id = C.m_product_id WHERE C.upc = '7094' AND B.m_pricelist_version_id = '1000020' 我得到以下错误PostgreSQL 8.2.11 ERROR: syntax error at or near "B"LINE 1: DELETE B.* f

DELETE B.* 
FROM   m_productprice B  
       INNER JOIN m_product C ON B.m_product_id = C.m_product_id 
WHERE  C.upc = '7094' AND B.m_pricelist_version_id = '1000020'

我得到以下错误PostgreSQL 8.2.11

ERROR:  syntax error at or near "B"
LINE 1: DELETE B.* from m_productprice B  INNER JOIN m_product C ON ...

我试过给

DELETE B from m_productprice B  INNER JOIN m_product C ON B....
 ERROR:  syntax error at or near "B"

我试过给

ERROR:  syntax error at or near "INNER"
LINE 1: DELETE from m_productprice B  INNER JOIN m_product C ON B.m_...

我的查询有什么问题？

DELETE 
FROM m_productprice B  
     USING m_product C 
WHERE B.m_product_id = C.m_product_id AND
      C.upc = '7094' AND                 
      B.m_pricelist_version_id='1000020';

要么

DELETE 
FROM m_productprice
WHERE m_pricelist_version_id='1000020' AND 
      m_product_id IN (SELECT m_product_id 
                       FROM m_product 
                       WHERE upc = '7094');
