Question

我尝试编写一个存储过程，以使事务号每天返回到01，但是当我运行它时，当天到01的所有事务号都不会增加。

然后我添加

and (V_JML_RECORD = 1) THEN V_JML_RECORD: = V_JML_RECORD +1;

当我运行它时，出现ORA-01422错误；所请求的行数是否有确切的准确回报，可以解释并为我的问题提供解决方案？

SELECT   TRIM (NAMA), TRIM (KD_KTR) AS KDKTR
INTO   V_NAMA, V_KDKTR
FROM   D_PRS
WHERE   TRIM (STB) = P_STB;

SELECT TO_CHAR (sysdate, 'MM') 
INTO V_BLNSKR
from dual;


SELECT TO_CHAR (sysdate, 'DD') 
INTO V_HRSKR
from dual;

SELECT COUNT(NOKAS) 
INTO V_JML_RECORD
FROM (
SELECT NOKAS,TGKAS,KTRASL FROM D_MSTHEADER_UKERJA WHERE TGKAS IN(
SELECT MAX(TGKAS) FROM D_MSTHEADER_UKERJA WHERE KTRASL=V_KDKTR)
)

IF (V_BLNSKR = '02')
AND (V_HRSKR = '27') THEN
  V_JML_RECORD := 1;

  ELSIF (V_BLNSKR = '02')
         AND (V_HRSKR = '27')
        AND (V_JML_RECORD = 1) THEN
 V_JML_RECORD := V_JML_RECORD +1;
 ELSE
   V_JML_RECORD := V_JML_RECORD +1;

  END IF;

要立即解决您的问题，请在下面的查询中添加ROWNUM = 1，但是正确的方法是让您通过检查原始查询的结果来检查哪一行是正确的行。使用INTO函数时，只需要获取一个单行查询即可。

SELECT   TRIM (NAMA), TRIM (KD_KTR) AS KDKTR
INTO   V_NAMA, V_KDKTR
FROM   D_PRS
WHERE   TRIM (STB) = P_STB AND ROWNM = 1;

ORA-01422：精确获取返回的行数超过了请求的行数ORA-06512
