Perfect (y) .. Love to see and learn through your lectures <3
You're the best
Thank you, Doctor Venkat. I have nothing better to offer you than to invite you to the greatest blessing in the universe, which is the blessing of Islam and enough for it to be grace .. God says change the religion of God they desire and for him the safest of the heavens and the earth voluntarily and his hatred and to him they return … He also says .. that religion is with God Islam and who seeks Other than the religion of Islam, it will not be accepted from him, and he is in the hereafter among the losers .. He also says .. There is no compulsion in religion, so whoever disbelieves the tyrant and believes in God, he adheres to the trustworthy loop, which is inseparable and God is All-Knowing.
Your voice is really soothing..

Hi venkat, greeting familiar yes
to insert update delete tutorial on C # what is not?
thank you so much for helping us.
continuation…if so can u show us how to cahnge the data using sqlexecutereader pls?
sqldatareader requires an active connection to the datasource,while reading data….what does it mean…pls tell us….thanks in advance
hi venkat ,
from this video v learned that sqldatareader is read only,forward only and requires active connection….
1)even sqlexecutereader also used to retrieve the records….
2)before v write cmd.sqlexecutereader v write connectin.open and same is the case with sqdatareader
so what is the difference between sqldatareader and sqlexecutereader…..pls clarify this doubt
3)from this video v learned that v cannot change the data using sqldatareader.can v change data using sqlexecuterader?
Thank you very much for taking time to give feedback. In the description of this video, I have included the link for ASP .NET, C#, and SQL Server playlists.

Besides closing the connection or the reader with the Using statement or in the Finally block, there is also another way which specify the "CloseConnection" behavior within the parentheses of the ExecuteReader method of a command object. It is one of the members of the CommandBehavior enumeration, and is generally being used as such SqlDataReader reader = cmd.ExecuteReader(CommandBehavior.CloseConnection). The connection will be closed automatically when the data reader is closed.
HI venkat….Can you plz share how to write a parameterised query that inlcudes WHERE clause..Because we cannot pass comma separated values as parameters directly…can you please shows us how to deal with these parametersied queries especially for WHERE and LIKE clauses..
Hello Sir,
I have solved the above error. Actually There was an issue with the name of the class which i had given to be SqlDataReader, which is an already existing class in Ado.Net Framework. So I changed the name of the class file and the issue was resolved. But thank you so much for checking it. And also, your videos are the source of tremendous knowledge. I have share them to as many Facebook Pages as I can, also with my juniors….
Hi Dhaval, is this error at compile time or at run time? Can you please post the code here.
To be specific, only this video.. Otherwise all the other videos are so helpful….

Can you help me with that please ??
