好不容易找到啦
下面是源代码。
需要设置参数的时候用“@”设置好变量,然后进行解决就可以啦。
name2
=
name2.Trim();
decimal smoney = money1 - money2;
// smoney = 10;
SqlCommand mycomm3 = new SqlCommand( " update userinfo set
account=@employeeid where name=' " + name2 + " ' " , Conn);
SqlParameter sp1 = mycomm3.Parameters.Add( " @employeeid " , smoney);
sp1.SourceColumn = " account " ; // 设置要更新的列
sp1.SourceVersion = DataRowVersion.Original; // 设置要更新的值的版本
decimal smoney = money1 - money2;
// smoney = 10;
SqlCommand mycomm3 = new SqlCommand( " update userinfo set
account=@employeeid where name=' " + name2 + " ' " , Conn);
SqlParameter sp1 = mycomm3.Parameters.Add( " @employeeid " , smoney);
sp1.SourceColumn = " account " ; // 设置要更新的列
sp1.SourceVersion = DataRowVersion.Original; // 设置要更新的值的版本
