SqlCommand read one value

Question

I have a problem with the value returned from SqlCommand, I have this code:

string sqlSelect = \"Select TOP 1 Quotation.SentToSupp as SentToSupp         


        

Answer 1

Use SqlCommand.ExecuteScalar method - Executes the query, and returns the first column of the first row in the result set returned by the query. Additional columns or rows are ignored.
