Question

如果这些条件满足，我正在更新名为“sample”的表中的两列，其值为5;

1）如果TABLE A.MEM_NBR = TABLE B.MEM_NBR AND TABLE B.M_ID = XXXX, AND TABLE B.CLCL = 1并最终使用类似TABLE A.ID = SAMPLE.ID的连接条件 2）如果这些条件不够，那么我们不需要更新表格。

但是我收到了一个错误;

SQL Error: ORA-00913: too many values 
00913. 00000 - "too many values".

需要一些关于上述更新脚本的帮助，以及我出错的地方。

我使用的脚本如下;

UPDATE SAMPLE 
SET SAMPLE.PCB = 5, SAMPLE.PCBP_Q = 5 
WHERE (
    SELECT * 
    FROM MEMBER_A A,S_NEW B 
    WHERE A.MEM_NBR = B.MEM_NBR 
        AND B.M_ID = 1111 
        AND B.CLCL = 1 
        AND B.ID = C.ID);

Answer 1

问题是您的子查询可以返回多个值。要解决此问题，您可以使用EXISTS关键字。（我还将连接转换为ANSI语法。）

UPDATE SAMPLE C
SET C.PCB = 5, C.PCBP_Q = 5 
WHERE EXISTS (
    SELECT 1 
    FROM 
        MEMBER_A A
        JOIN S_NEW B 
        ON A.MEM_NBR = B.MEM_NBR 
        AND B.M_ID = 1111 
        AND B.CLCL = 1 
    WHERE 
        A.ID = C.ID);

你的情况可能是错的。它导致匹配许多值而没有映射

试试这个

UPDATE SAMPLE 
SET SAMPLE.PCB = 5, SAMPLE.PCBP_Q = 5 
WHERE ColumnNmae IN (
    SELECT ColumnName 
    FROM MEMBER_A A,S_NEW B 
    WHERE A.MEM_NBR = B.MEM_NBR 
        AND B.M_ID = 1111 
        AND B.CLCL = 1 
        AND B.ID = C.ID);

或者使用像这样的相关子查询：

UPDATE SAMPLE 
SET SAMPLE.PCB = 5, SAMPLE.PCBP_Q = 5 
WHERE EXISTS (
    SELECT 1
    FROM MEMBER_A A,S_NEW B 
    WHERE A.MEM_NBR = B.MEM_NBR 
        AND B.M_ID = 1111 
        AND B.CLCL = 1 
        AND B.ID = C.ID
        AND A.ColumnNmae = SAMPLE.ColumnNmaes);
