oracle - 带有IF的Oracle游标，需要帮助

Question

我正在努力使用光标，尝试了不同的版本但没有运气，并决定在这里寻求帮助。如何使 IF 条件起作用？我必须计算一些东西，然后检查这个计数是否大于 10，然后删除一些东西。如何将 count(*) 传递给 IF 条件然后执行某些操作？提前致谢。

 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

在声明中：

COUNT_VAR NUMBER(38);

体内：

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;
