Question

我发现了这个＆＃34; DECLARE CURSOR＆＃34;关于WWW的声明：

CREATE OR REPLACE PROCEDURE "APART21C"."FIND_VALID_ARZTNRN"
(OUT NoOfRows BIGINT)
RESULT SETS 1
LANGUAGE SQL
SPECIFIC SQL140905135133600
BEGIN

  DECLARE myARZTNR CHAR(7);
  DECLARE END_TABLE INT DEFAULT 0
  ;
  DELETE FROM APART21C.TMP_LANR07_CHECK
  ;
  DECLARE C1 CURSOR FOR
  SELECT DISTINCT Arztnr 
  FROM APART21C.DMP_LEV_TMP
  ;
  DECLARE CONTINUE HANDLER FOR NOT FOUND
   SET END_TABLE = 1
  ;
  OPEN C1
  ;
  FETCH C1 INTO myARZTNR
  ;
  WHILE END_TABLE = 0 DO

        INSERT INTO APART21C.TMP_LANR07_CHECK
        SELECT * FROM TABLE(APART21C.CHECK_ARZTNR_BY_CHECKSUM(myARZTNR)) AS ARZTNRCHECK;
        SET NoOfRows = NoOfRows + 1;

        FETCH C1 INTO myARZTNR;

  END WHILE
  ;
  CLOSE C1
  ;
END

错误消息是

"DB2 SQL Error: SQLCODE=-104, SQLSTATE=42601, SQLERRMC=<cursor declaration>;;<SQL statement>"

需要你的帮助

我是db2的初学者，我在MS SQL Server方面有更多经验。语句＆＃34; SELECT * FROM TABLE（...＆＃34;调用函数返回一个表。 R上。

以下代码出现问题

DECLARE C1 CURSOR FOR SELECT DISTINCT Arztnr 来自APART21C.DMP_LEV_TMP

我已更改如下并执行

DECELARE C1 CURSOR with HOLD FOR SELECT Arztnr FROM DMP_LEV_TMP;
