SQuirrel 调用存储过程

问题描述

我正在尝试从 Squirrel 调用 DB2 存储过程。 我可以从 DB2 命令行成功调用存储过程 处理器。

 CALL PIPPOOWN.PIPPO
('04','prov','0001','provprov')

我将 ;retrieveMessagesFromServerOnGetMessage=true; 附加到数据库的连接字符串。

jdbc:db2://xx.xx.x.xx:50001/DB2XYX:retrieveMessagesFromServerOnGetMessage=true;

但是当我在 Squirrel 中尝试此操作时，我收到此错误消息。我在跑步

Error: [jcc][10413][10940][4.19.49]
Analisi della sostituzione letterale non riuscita per la chiamata della procedura a DB2 per z/OS.

我更新了 jdbc 驱动程序，但我没有修复。

DB2 版本：11.01

如果我使用 IBM DATA STUDIO 或我使用 DB2 AIX，它就可以工作。

我下载了“IBM Data Server Driver for JDBC and SQLJ (JCC Driver)”Version 11.5.4，然后我将其配置为使用 db2jcc4.jar 现在它给出了以下错误：

NO AUTHORIZED PROCEDURE NAMED PIPPOOWN.PIPPO HAVING COMPATIBLE ARGUMENTS WAS FOUND. 
SQLCODE=-440,SQLSTATE=42884,DRIVER=4.26.14 SQL Code: -440,SQL State: 42884

但是如果我使用 IBM DATA STUDIO 和相同的用户和语句，我不会出错

存储过程“PIPPO”- GRANT

GRANT EXECUTE ON PROCEDURE "PIPPOOWN"."PIPPO" TO "ALL";
GRANT EXECUTE ON PROCEDURE "PIPPOOWN"."PIPPO" TO "PUBLICB";
GRANT EXECUTE ON PROCEDURE "PIPPOOWN"."PIPPO" TO "PIPPOOWN" WITH GRANT OPTION;
GRANT EXECUTE ON PROCEDURE "PIPPOOWN"."PIPPO" TO "USERWEB";
GRANT EXECUTE ON PROCEDURE "PIPPOOWN"."PIPPO" TO PUBLIC;

存储过程“PIPPO” - 分发选项（使用数据洞察）

CURRENT_PATH BY SQUIRREL

SELECT CURRENT_PATH FROM SYSIBM.SYSDUMMY1

RESULTS
-----------------------------------------------
"SYSIBM","SYSFUN","SYSPROC","SYSIBMADM","PIPPOOWN"

最后，我在 Squirrel 日志中找不到任何错误。

有什么想法吗？

我在 Squirrel 上执行 call 语句，启用 JDBC 日志，发现这个错误：

为了比较不同的日志，我还激活了 IBM DATA STUDIO JDBC 日志（其中 CALL 语句正常工作），我注意到在执行 execute() 之前完成了 prepareCall()。

I looked in the [IBM documentation][4] and it seems that in order to call SP with parameters in the Z/OS environment,it is necessary to perform a PreparedStatement.

此时我认为是松鼠BUG...

解决方法

我试图打开一个 BUG：squirrel-sql:bugs#1457 在 DB2 z/os 上使用输入参数调用存储过程
