有谁知道吗！？？这是啥原因

[fangxianghua9801]

asp.net查询MSSQL2000时总出现这样的错误：不允许从数据类型 datetime 到 int 的隐性转换。请使用 CONVERT 函数来运行此查询。

[xiaoqhuang]

代码？

[seesharp]

晕,原因不是写的很清楚吗?
不允许从数据类型 datetime 到 int 的隐性转换

[xingyaohua]

错误已经很清晰了
数据类型 datetime 到 int 转换错误

你把那段出错的代码写出来才知道哪句出错了。

[fangxianghua9801]

各位兄台，我是用了上面的通用翻页存储过程才有这样的错误

[dlzhangln]

CONVERT(int, col2)

[xiaoqhuang]

你看一下哪个字段为DateTime，查询出来的DateTime是否赋值给了int型。或把int赋给DateTime了
