c#调用oralce函数错误(孟子等高手来,救救我)
不知道该如何调用这个函数,大哥大姐们,都来帮帮忙啊!!
函数如下,该函数有返回的是1,
具体的函数体不需要看,前两天有人告诉我使用 select cs_csjs_zz(4102006102900000037,2007,1,1,99) as return_value from dual这种方法来调用函数,但是出现错误
ORA-14552: cannot perform a DDL, commit or rollback inside a query or DML
ORA-06512: at "FINAPP.CS_CSJS_ZZ ", line 74
ORA-14551: cannot perform a DML operation inside a query
select cs_csjs_zz(4102006102900000037,2007,1,1,99) as return_value from dual

[解决办法]
自己可以先在PL/SQL面一下啊
[解决办法]
错误提示很明显：查询中不能执行数据定义或者commit，rollback等操作
[解决办法]
CALL cs_csjs_zz(4102006102900000037,2007,1,1,99)就可以了

使用C#中的方法直接执行这句话,也可以带参数

参考MSDN
[解决办法]
楼主,没有看清楚,你写的是function

你应该这样写
BEGINE

numReturn := CS_CSJS_ZZ(4102006111100000014,2007,1,1,99);

END;

大概是这样的，具体你再去看看。

我的理解是call 只能调procedure ，不能直接调function 。所以你只能把它放在一个模块中。

大概是这样的，搂住可以再试试。你也可以把你的function 定义为procedure ，使用原来的方法调用。
