<P>
<P>一般在.NET中连接数据库,然后因为某些列要进行自动计算(根据其它列值的结果),有朋友可以在数据库中定义"计算列",确实在部分情况下在数据库在定义"计算列"可以解决问题,但是如果对应的"计算公式"是变化的,例如:工资的计算公式,那么就不能每次修改数据库的"计算列"来处理,于是用到了.NET中的dt.Columns["列"].Expression属性,但这个属性一但设置好后,是可以计算出正常的结果,并显示于DataGridView中,但在提交更新da.Update(dt)时会出现"来自 
SourceColumn“列”的列映射失败，原因在于 DataColumn“列”是计算所得的列。",此原因是由于约束造成的.解决此问题的办法:</P>
<P>1.遍历DataGridView或dt中各行的值,依次插入到数据库中</P>
<P>2.遍历DataGridView或dt中各行的值,依次插入到另一个另一个dt中,再update</P>
<P>以上两法都行,但由上两法简处理得:</P>
<P>DataTable dt1 = dt.Clone();<BR>for (int i = 0; i &lt; dt1.Columns.Count; 
i++)<BR>{<BR>dt1.Columns[i].Expression = 
null;<BR>}<BR>dt1.Merge(dt);<BR>da.Update(dt1);</P>
<P>道理同上一样,当然你得生成UpdateCommand与其它命令.</P>
<P>注意:</P>
