【问题标题】：DB2 Stored Procedure parameter "is not valid in the context where it is used"DB2 存储过程参数“在使用它的上下文中无效”

【问题描述】：

我正在尝试创建以下存储过程：

-- <ScriptOptions statementSeparator="@"/>
-- <ScriptOptions errors="off" platform390="off"/>
@
DROP SPECIFIC PROCEDURE DEPCLH.GetTransactionSummaryByDateRange@

CREATE PROCEDURE  DEPCLH.GetTransactionSummaryByDateRange (in p_DCHDSB_ID INTEGER,in p_StartDate varchar(50),in p_EndDate varchar(50)) 
SPECIFIC  DEPCLH.GetTransactionSummaryByDateRange
LANGUAGE SQL
RESULT SET 1@

BEGIN

DECLARE C_OUTPUT CURSOR WITH RETURN FOR
SELECT
sub.DCHDSB_ID AS FACILITYID,
sub.DCHDSB_CODE AS FACILITYCODE,
sub.NAME AS FACILITYNAME,
SUM(dep.AMOUNT) "TOTALAMOUNT",
COUNT(*) "TRANSACTIONCOUNT"
FROM DEPCLH.DEPOSIT_SUBSCRIBER sub
INNER JOIN DEPCLH.DEPOSIT dep ON dep.DCHDSB_ID=sub.DCHDSB_ID
WHERE sub.DCHDSB_ID=p_DCHDSB_ID AND dep.CREATED_TS BETWEEN p_StartDate AND p_EndDate
GROUP BY sub.DCHDSB_ID,sub.DCHDSB_CODE,sub.NAME
FOR READ ONLY;

OPEN C_OUTPUT;

END 
@

GRANT EXECUTE ON SPECIFIC PROCEDURE  DEPCLH.GetTransactionSummaryByDateRange TO PUBLIC
@

COMMIT
@

我收到以下错误：

DB21034E 该命令被作为 SQL 语句处理，因为它是不是有效的命令行处理器命令。在 SQL 处理期间返回：SQL0206N“P_DCHDSB_ID”在它所在的上下文中无效用来。第 3 行。 SQLSTATE=42703

【问题讨论】：

我认为问题在于你在CREATE PROCEDURE语句中间有一个语句终止符@：LANGUAGE SQL RESULT SET 1@ BEGIN
@mustaccio 这就是问题所在。谢谢你。上面发布的解决方案。

在代码中发现错字。谢谢你的好眼光！
