Trying to open a stored procedure in query view
passing a parameter from access

Will not open stored procedure

Dim cnn As ADODB.Connection
Dim rst As ADODB.Recordset
Dim cmd As ADODB.Command
Dim strConnect As String
Dim ACCOUNT_NUMBER As String

strConnect = "provider=sqloledb;Server=RMDB5.campus.com;Database=SS_Pro;Uid=xxxx;Pwd=xxxx;"

' Instantiate the connection object
Set cnn = New ADODB.Connection

' Open the connection based on the strConnect connect string arguments
cnn.Open strConnect

' Instantiate the command object
Set cmd = New ADODB.Command


ACCOUNT_NUMBER = Me.SUPPLIER_LOOKUP

' Assign the connection and set applicable properties
cmd.ActiveConnection = cnn
cmd.CommandType = adCmdStoredProc
cmd.CommandText = "sp_qsupp_LOOKUP"



cmd.Parameters.Append cmd.CreateParameter("@Account", adVarChar, adParamInput, 10, ACCOUNT_NUMBER)
Set rst = cmd.Execute

Set rst = Nothing
Set cnn = Nothing
Set cmd = Nothing

Open in new window

any error(s)

note that so far, you only execute the procedure, but do nothing with the data (if any)

I see this line:
cmd.ActiveConnection = cnn

in vba, it should be:
set cmd.ActiveConnection = cnn

otherwise you are only passing the connection string, and not the open connection ...

Try to execute it directly in SQL server and see if it returns anything. If yes then change your code to actually grab the result set and do something with it.

.execute is used to run an action query or sp on the server.  It doesn't return a result set.
.openrecordset is used to open a recordset that you can manipulate via vba

There is no ADO or DAO method that opens a recordset you can interact with in the GUI.  If you want to present the recordset to the user, bind it to a form or report and open that.

ok, I guess, a little baffled.
I have a pass through query now.
I have the DSN connection string stored in the pass through query.

I simply do this do view the stored procedure from sql server.
DoCmd.OpenQuery "sp_Vendor_Detail"
I see the results.

I created another stored procedure on sql server named
 "sp_Pass_Vendor_Detail"

but i must pass a variable to sql server from access.

DoCmd.OpenQuery is an Access VBA command.  It is NOT ADO, it is NOT DAO.  It works differently in that it works with the Access GUI.  DAO and ADO are not tied to Access.  They can be used from any application that supports them.  I think DAO only works with VB, VBA, and VBScript but ADO has a .net option that works with any .net language.  They do not work with any GUI.  They are batch only operations.

However, you can open an ADO recordset and bind it to a form or report.  That crosses the bridge to allow you to use the Access GUI.

so once i get to this part:
cmd.Parameters.Append cmd.CreateParameter("@Account", adVarChar, adParamInput, 10, ACCOUNT_NUMBER)
Set rst = cmd.Execute

How do i view the recordset ?

I don't use ADO so I can't give you an example.  I think it is similar to the DAO method which is

Dim db as DAO.Database
Dim td as DAO.Tabledef
Dim rs as DAO.Recordset
    Set db = CurrentDb()
    Set td = db.TableDefs!tblImportLog
    Set rs = td.OpenRecordset

this is working as far as executing the code: and returning a records.


BUT, I need to see/view those records in a query ??????


Dim cnn As ADODB.Connection
Dim rst As ADODB.Recordset
Dim cmd As ADODB.Command
Dim strConnect As String
strConnect = "provider=sqloledb;Server=PR.campus..com;Database=SS_flow;Uid=xxx;Pwd=xxxx;"
' Instantiate the connection object
Set cnn = New ADODB.Connection
' Open the connection based on the strConnect connect string arguments
cnn.Open strConnect
' Instantiate the command object
Set cmd = New ADODB.Command
' Assign the connection and set applicable properties
cmd.ActiveConnection = cnn
cmd.CommandType = adCmdStoredProc
cmd.CommandText = "sp_qsupp_LOOKUP"
' Instantiate the recordset object by using the return value
' of the command's Execute method. Supply the parameters by
' packing them into a variant array
cmd.Parameters.Append cmd.CreateParameter("@Account", adVarChar, adParamInput, 10, ACCOUNT_NUMBER)
Set rst = cmd.Execute()

We're going in circles here.  If you want to view the resultset, bind it to a form or report.  No ADO method will open a query for you to view.

Did you try creating a passthrough query?  The problem is the argument.  You can't have a passthrough query that takes an argument.  Therefore, you must create the passthrough query using VBA with embedded arguments.  Save the query.  Then you can open the saved querydef with the GUI as long as its returns records property is set to yes.

You cannot do what you are trying to do by using ADO in code.

Do you actually need to run a stored procedure?  Can you create a view?  You can link to the view and work with it as you would with a linked table.  Typically stored procedures do stuff.  They don't gather data for presentation.  You use views and Access queries for that.
