- Data Reader apply only Select Statement, It can featch data from multiple Table Through Multiple Select Statement separated by Semicolon(;) Likes For Ex:
SqlCommand cmd=new SqlCommand("Select * from Emp";" Select * From Dept",Con);
DataReader dr=cmd.ExecuteReader();
dr.NextResults();
Here NextResults() Navigate from One Tables to Anather Tables
- It is Readonly, It can featch single Record At a Time..
