Question

I used the select disctinct statement with 2 fields from my sql database table. Here is my code.

myCommand = New SqlCommand("SELECT DISTINCT Author FROM tblBook UNION SELECT DISTINCT BookCode FROM tblBook",myConnection)
 myAdapter = New SqlDataAdapter(myCommand)
 myAdapter.Fill(myDataSet, "tblBook")
 cboAuthor.DataSource = myDataSet.Tables(0)
 cboAuthor.DisplayMember = "Author"
 cboAuthor.DisplayValue = "BookCode"

and it generates error : cannot bind to the new member. Parameter name:value. Please help

Answer 1

you have selected only one column in your sql statement, Author.
BookCode isn’t present so it won’t be in the dataset either.

Include the BookCode in the Sql Statement and it will be fixed
