Hello, I'm trying to populate a label from the data that is being returned from a SQL query, but keep getting an error: must declare the varible @stringm163

Can someone please look at my code below and show me where I'm going wrong?

Sub getUser()
Dim conn As ADODB.Connection
Dim connString As String

connString = "Provider=sqloledb;Data Source=localhost;Initial Catalog=test;User Id=scott;Password=rocks"

Set conn = New ADODB.Connection
conn.ConnectionString = connString
conn.Open connString

Dim rs As ADODB.Recordset
Dim sSQL As String

Set rs = New ADODB.Recordset
sSQL = "select username from cstb_sopWindowUsers where username = @StringM163"
rs.Open sSQL, conn

StringM164.Value = rs.Fields.Item("username").Value

Set conn = Nothing
Set rs = Nothing
End Sub

    Is @StringM163 a field name, or a SQL Server parameter?

    Field name...
    sSQL = "select username from cstb_sopWindowUsers where username=" &  YourFormName.[ @StringM163]

    SQL Server parameter...
    You'll need an ADODB.Command object, create/set an ADODB.Parameter of @StringM163, then execute your command.

    (slight correction, string needs to be surrounded by single tick marks)
    sSQL = "select username from cstb_sopWindowUsers where username='" &  YourFormName.[ @StringM163] & "'"

    Thank you Jim for responding. I'm trying to obtain the value from a field. I'm using:

    sSQL = "select username from cstb_sopWindowUsers where username='" &  SalesTransactionEntry.[ @StringM163] & "'"  
    but am now getting this error method or data member not found

    SQL may not allow you to name fields with a punctuation mark as the first character.  

    Even if it does, this is highly confusing, as the @ character is usually the prefix for stored procedure variables, and it will force you to use square brackets [ ] to refer to it.

    Try renaming your field something meaningful, such as txtUser, txtCustomer, anything instead of @StringM163, and try again.

    sSQL = "select username from cstb_sopWindowUsers where username='" &  SalesTransactionEntry.txtUser & "'"

    Sorry, but I had the @ character as if I were passing a variable to a SPROC.  I took out the @ and now it works great! Thank you very much for your assistance Jim.
