I have the following code:
public DataTable opencon(PAL.property objpal)
{
string query = "Select UserId,Firstname,UserType from TBL_USER_LOGIN where Username=@username and Password=@password and Status=1";
OleDbCommand objcmd = new OleDbCommand();
objcmd.CommandText = query;
objcmd.Connection = oldbcon;
oldbcon.Open();
objcmd.Parameters.Add("@username", OleDbType.VarChar).Value = objpal.username;
objcmd.Parameters.Add("@password", OleDbType.VarChar).Value = objpal.Password;
DataTable dt = new DataTable();
OleDbDataAdapter adp = new OleDbDataAdapter(objcmd);
adp.Fill(dt);
return dt;
}
Here I want to fetch some values from the table according to a condition, but when I run this code it shows the following error:
Even though I passed the correct parameters value in @username and @password. How can I resolve this error? Please help.
Try This:
public DataTable opencon(PAL.property objpal)
{
string query = "Select UserId,Firstname,UserType from TBL_USER_LOGIN where Username=? and Password=? and Status=1";
OleDbCommand objcmd = new OleDbCommand();
objcmd.CommandText = query;
objcmd.Connection = oldbcon;
oldbcon.Open();
objcmd.Parameters.Add("@username", OleDbType.VarChar).Value = objpal.username;
objcmd.Parameters.Add("@password", OleDbType.VarChar).Value = objpal.Password;
DataTable dt = new DataTable();
OleDbDataAdapter adp = new OleDbDataAdapter(objcmd);
adp.Fill(dt);
return dt;
}
Try This
string query = "Select [UserId],[Firstname],[UserType] from [TBL_USER_LOGIN] where [Username]=? and [Password]=? and [Status]=1";
