                    }

Why would that write anything to your database? If you want to insert anything into your database, you use "Insert Into...". I think you need to learn some SQL.

thank you ... now i know that i really dont know sql...

instead of:
string sssql = "SELECT *FROM
use:
string sssql = "SELECT * FROM
there must be a space after the (*) sign

mmaenb, you are wrong sir. I have just tested in SQL Server Management Studio and you can do Select *From TableName and it runs fine. It is proper to have a space after for readability, however it is not mandatory.

moshe12007, take a look at this for inserting into a database, http://msdn.microsoft.com/en-us/library/ms233812(v=vs.80).aspx

Also look at using stored procedures so that you don't get SQL injections.

First all add space after *.If it does not work then check your table is there are entries or not.

You need to use UPDATE statement to update rows.

sql="update BooksCatalog set BorrorState='good' WHERE BookID = '" + TB[2].Text + "'";
