Proper syntax to retrieve field from SQL table?
In Code Behind, What is proper select statement syntax to retrieve the @BName field from a table?
Using Visual Studio 2003
SQL Server DB
I created the following parameter:
Dim strName As String
Dim parameterBName As SqlParameter = New SqlParameter("@BName", SqlDbType.VarChar, 50)
parameterBName.Value = strName
myCommand.Parameters.Add(parameterBName)
I tried the following but get error:
Dim strSql As String = "select @BName from Borrower where BName= DOROTHY V FOWLER "
error is:
Line 1: Incorrect syntax near 'V'.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

First of all, it looks like @BName is the name of a parameter, not a field; I don't think SQL Server allows field names that begin with '@'. Second, you're trying to execute a query (a SQL statement that returns one or more records), but you're calling ExecuteNonQuery to do it. ExecuteNonQuery is intended for SQL statements (such as INSERT, UPDATE and DELETE commands) which do not return records.

Sorry: To further clarify
My database table name is borrower and two of the fields are BName and TaxID, I am trying to select a particular borrower (BName) with a taxid OF 767, lets say in this case THE BORROWER IS Bill Jones
I declared the following variables:
Dim strName As String
Dim parameterBName As SqlParameter = New SqlParameter("@BName", SqlDbType.VarChar, 50)
parameterBName.Value = strName
myCommand.Parameters.Add(parameterBName)
Dim strTaxID As String
Dim ParameterTaxID As SqlParameter = New SqlParameter("@TaxID", SqlDbType.VarChar, 15)
ParameterTaxID.Value = strTaxID
myCommand.Parameters.Add(ParameterTaxID)
I inserted the folowing command:
Dim strSql As String = "select BName from Borrower where TaxID= @333-00-1492 "
I get error:
Must declare the variable '@333'.
