Question

在ORACLE SQL Developer上运行时，给定查询执行正常。但是在通过java代码执行时抛出ORA-00923: FROM keyword not found where expected。

UPDATE RESTRICTED_MARKET_OWNER
SET OWNER_ID='abc'
WHERE OWNER_ID='xyz' AND RESTRICTED_MARKET_ID IN
(
    SELECT M.RESTRICTED_MARKET_ID
    FROM RESTRICTED_MARKET M, RESTRICTED_MARKET_OWNER RM
    WHERE RM.RESTRICTED_MARKET_ID = M.RESTRICTED_MARKET_ID AND
          M.RELEASE='Rel123' AND RM.OWNER_ID='xyz'
)

关于此

的任何建议

Java查询

    UPDATE RESTRICTED_MARKET_OWNER SET OWNER_ID=? WHERE OWNER_ID=? AND RESTRICTED_MARKET_ID IN ( SELECT M.RESTRICTED_MARKET_IDFROM RESTRICTED_MARKET  M  , RESTRICTED_MARKET_OWNER RM WHERE RM.RESTRICTED_MARKET_ID=M.RESTRICTED_MARKET_ID AND M.RELEASE=? AND RM.OWNER_ID=? )

pstmt.setString(1, 'abc');
pstmt.setString(2, 'xyz');
pstmt.setString(3, 'Rel123');
pstmt.setString(4, 'xyz');
pstmt.executeUpdate();

在Java查询中似乎是一个拼写错误，表名与FROM关键字之间缺少空格：

SELECT M.RESTRICTED_MARKET_IDFROM RESTRICTED_MARKET M.

因此，更正语法将使您的查询正常工作。

ORA-00923：未找到FROM关键字在哪里查询
