ADO Command Parameter Not Passing to Stored Procedure or Stored Procedure 'Ignoring' Parameter

Question

Update 4

Updated the whole question to reflect my changes. Still Not Working.

This has been annoying me for two days now. I\'m updating an old ordering int

Answer 1

Solved

Thank you to Bond and especially Lankymart for your help. Lankymart, your suggestion to use SQL Profiler helped. My server has the older version I guess - Profiler.

I found this when looking in the Profiler Trace: @SearchQuery = 'bww100052 '

So I decided to force a Trim inside the stored procedure: LTRIM(RTRIM(@SearchQuery))

Stored Procedure

CREATE PROCEDURE dbo.sp_PalletSearch
@CustomerRef        Int,
@SearchQuery        VarChar(15) = '%'
AS    

SET NoCount On  
SET @SearchQuery = '%' + COALESCE(LTRIM(RTRIM(@SearchQuery)), '%') + '%'

SELECT      p.PalletID,
            p.PalletCode
FROM        dbo.v_PalletSearch p
WHERE       p.CustomerRef   = @CustomerRef
AND         p.PalletCode    LIKE @SearchQuery
ORDER BY    p.PalletCode    ASC

SET NoCount Off
GO

ADO Command

Dim objCmd
Set objCmd = Server.CreateObject("ADODB.Command")
objCmd.ActiveConnection = cConn
objCmd.CommandType = adCmdStoredProc
objCmd.CommandText = "sp_PalletSearch"
objCmd.Parameters.Append objCmd.CreateParameter("@CustomerRef", adInteger, adParamInput)
objCmd.Parameters.Append objCmd.CreateParameter("@SearchQuery", adVarChar, adParamInput, 15)
objCmd.Parameters("@CustomerRef").Value = CustomerID
objCmd.Parameters("@SearchQuery").Value = Trim(strSearchQuery)

Dim objRS
Set objRS = objCmd.Execute
Set objCmd = Nothing

Finally

I thought I would never solve this one, it was just making no sense at all! I'll throw a few more tests at it, but it looks like trimming the variable was needed. I don't know why the extra space was added though.

Answer 2

I think you causing yourself more issues by trying anything and everything. With each attempt you make slight mistakes in your syntax (like quotes in the wrong place, not specifying a CommandType etc).

If it helps this is how I would code for that stored procedure

Dim cmd, rs, sql
Dim data, rows, row

Set cmd = Server.CreateObject("ADODB.Command")
'Name of your stored procedure
sql = "dbo.sp_PalletSearch"

With cmd
  .ActiveConnection = cConn 'Assuming cConn is a connection string variable
  .CommandType = adCmdStoredProc
  .CommandText = sql
  'Define Stored Procedure parameters
  Call .Parameters.Append(.CreateParameter("@CustomerRef", adInteger, adParamInput, 4))
  Call .Parameters.Append(.CreateParameter("@SearchQuery", adVarChar, adParamInput, 15))
  'First parameter is optional so only pass if we have a value, will default to NULL.
  If Len(CustomerId) > 0 Then .Parameters("@CustomerRef").Value = CustomerID
  .Parameters("@SearchQuery").Value = strSearchQuery
  Set rs = .Execute()

  'Populate 2D-Array with data from Recordset
  If Not rs.EOF Then data = rs.GetRows()

  'Close and Release Recordset from memory
  Call rs.Close()
  Set rs = Nothing
End With
Set cmd = Nothing

If IsArray(data) Then
  rows = UBound(data, 2)
  For row = 0 To rows
    Call Response.Write("Pallet Id: " & data(0, row) & " | Pallet Code: " & data(1, row) & "</ br>")
  Next
End If

Answer 3

Try it with

objCmd.Parameters.Append objCmd.CreateParameter("@SearchQuery", adVarChar, adParamInput, 15, "'PalletCode'")

Notice that "'PalletCode'" has an additional set of single quotes inside of it.
