Question

我正在用光标挣扎，尝试了不同的版本而没有运气，并决定在这里寻求帮助。如何使IF条件工作？我必须计算一些东西，然后检查这个数是否大于10，然后删除一些东西。如何将计数（*）传递给IF条件然后再做一些事情？提前谢谢。

 DECLARE
  CURSOR MY_CURSOR
      IS

SELECT CSH.STATUSCHANGEDDATE AS STATUSCHANGEDDATE_, CSH.CUSTOMER AS CUSTOMER_ from        CUSTOMER_STATUSES csh WHERE 
csh.STATUSCHANGEDATE>SOME_DATE AND CSH.STATUS = 'X_STATUS'


 MY_RECORD MY_CURSOR%ROWTYPE;

    BEGIN
      OPEN MY_CURSOR;
      LOOP
        FETCH MY_CURSOR INTO MY_RECORD;
        EXIT
      WHEN MY_CURSOR%NOTFOUND;


SELECT COUNT(*) FROM SOME_TABLE WHERE SOME_DATE = STATUSCHANGEDDATE_ AND ....

    iF ABOVE_COUNT = 10 THEN
        DELETE * FROM SOME_TABLE2 WHERE SOME_CONDITION2
  ELSE 
 END IF

      END LOOP;
END LOOP;
 COMMIT;
END;

Answer 1

声明：

COUNT_VAR NUMBER(38);

身体：

SELECT COUNT(*) INTO COUNT_VAR
FROM SOME_TABLE 
WHERE SOME_DATE = STATUSCHANGEDDATE_ AND ....;

IF COUNT_VAR = 10 THEN
    DELETE * FROM SOME_TABLE2 WHERE SOME_CONDITION2;
END IF;

带有IF的Oracle游标，需要帮助
