从数据库中找到符合条件的记录,进行更新!
为何老报错"对于不返回任何键列信息的 SelectCommand 不支持 UpdateCommand 的动态 SQL 生成。"?
如何修改呢,我刚学ASP.net,请多多照顾
string m_sql="select * from item where id=2277";
SqlConnection sqlConnection1=new SqlConnection(strConn);
SqlDataAdapter sqlDataAdapter1=new SqlDataAdapter(m_sql,sqlConnection1);;
DataSet dataset=new DataSet();
SqlCommandBuilder sqlcommandbuilder=new SqlCommandBuilder(sqlDataAdapter1);
sqlConnection1.Open();
sqlDataAdapter1.Fill(dataset,"ly");
sqlConnection1.Close();
if (dataset.Tables[0].Rows[0]["item_serial"].ToString()=="048")
{
Label1.Text="Yes";
dataset.Tables[0].Rows[0]["item_serial"]="hello"
sqlDataAdapter1.Update(dataset,"ly");
}
else
{
Label1.Text="NO";
