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


函数:
