Question

我有一个问题，将选定的多行存储在变量（或我不知道的表变量）中。我认为有可能使其工作。这是我的代码

  SELECT RECIPIENT, COUNT (*) N_CNT
    FROM (SELECT RECIPIENT,
                 SERVICE_TYPE,
                 MPS_SWTCH_CD,
                 MPS_FTR_CD1
            FROM ABA_RM_INB_USAGE
           WHERE SERVICE_TYPE = 100
              OR SERVICE_TYPE = 0
             AND MPS_SWTCH_CD = 'T11'
             AND MPS_FTR_CD1 = 1033)
GROUP BY RECIPIENT

此查询显示已过滤的行，我需要将该行插入到另一个表中。对不起，英语不好

我不确定，您想要实现什么。

如果您要从一个表中进行选择并插入到另一个表中，则可以在您的选择周围包裹一个插入语句：

INSERT INTO TABLE_RECIPIENT_COUNT
      SELECT RECIPIENT, COUNT (*) N_CNT
        FROM (SELECT RECIPIENT,
                     SERVICE_TYPE,
                     MPS_SWTCH_CD,
                     MPS_FTR_CD1
                FROM ABA_RM_INB_USAGE
               WHERE SERVICE_TYPE = 100
                  OR SERVICE_TYPE = 0
                 AND MPS_SWTCH_CD = 'T11'
                 AND MPS_FTR_CD1 = 1033)
    GROUP BY RECIPIENT;

如果要在plsql脚本（或过程..）中执行此操作，则可以定义类型或遍历游标。这是一个如何遍历游标并处理数据的示例：

DECLARE
    CURSOR cur
    IS
          SELECT RECIPIENT, COUNT (*) N_CNT
            FROM (SELECT RECIPIENT,
                         SERVICE_TYPE,
                         MPS_SWTCH_CD,
                         MPS_FTR_CD1
                    FROM ABA_RM_INB_USAGE
                   WHERE SERVICE_TYPE = 100
                      OR SERVICE_TYPE = 0
                     AND MPS_SWTCH_CD = 'T11'
                     AND MPS_FTR_CD1 = 1033)
        GROUP BY RECIPIENT;
BEGIN
    FOR item IN cur -- if you realy want to insert all results you should read about BULK-COLLECT and FORALL ;-)
    LOOP
        dbms_output.put_line('Result: ' || item.RECIPIENT || ', ' || item.N_CNT);
        INSERT INTO TABLE_RECIPIENT_COUNT
             VALUES (item.RECIPIENT, item.N_CNT);
    END LOOP loop_emp;
END;
