“=”附近有语法错误。

ck36

我在执行一个action的时候，报出【“=”附近有语法错误。】的问题。

action中的sql语句是调用了一个已经存在的存储过程，在保证传参没问题的情况下，在数据库中调用存储过程正常运行，但在BEX5中调用就会报错。

具体错误信息：

另外在制作excel报表的时候遇到了困难，有没有详细的教程或者demo可以查阅？

jishuang

错误是baas报错的，BeX5一般用的BIZ不用baas

GvA.Storeprocedure.CheckRecipe(Storeprocedure.java:102)代码调试跟踪一下

BeX5做excel报表要用BIZ不能用baas

BeX5的初级视频中有说明https://pan.baidu.com/s/1qXZ80AK
/BIZ/demo/report  /UI2/demo/report下有案例

GvA.Storeprocedure.CheckRecipe(Storeprocedure.java:102) ...

好的，谢谢。
但目前交到我这边的内容是用到了已经搭建好的数据库结构和相关存储过程，重新改用BIZ做会不会需要很多工作量？

jishuang

用BIZ对应的action需要重新定义

还想问一下，如果在biz中想使用自己用jdbc写的action是否可行

jishuang

可以，就是java标准的
