SQL doesn’t have access to your asp.net context, it can’t access form components so doesn’t know what \"txteid.Text\" is. Even if it did it would make no sense as you set @eid to the same value, so if it was \"1\" your query would be \"where 1 = 1\" which applies to all records. Instead you need to use the name of the column in the master table that you want to match the value of txteid.Text. We can’t see your database so don’t know what that is, but if the field is called \"id\" then you need;
