How do I associate Parameters to Command objects in ADO with VBScript?
- by Krashman5k
I have been working an ADO VBScript that needs to accept parameters and incorporate those parameters in the Query string that gets passed the the database. I keep getting errors when the Record Set Object attempts to open. If I pass a query without parameters, the recordset opens and I can work with the data. When I run the script through a debugger, the command object does not show a value for the parameter object. It seems to me that I am missing something that associates the Command object and Parameter object, but I do not know what. Here is a bit of the VBScript Code:
...
'Open Text file to collect SQL query string'
Set fso = CreateObject("Scripting.FileSystemObject")
fileName = "C:\SQLFUN\Limits_ADO.sql"
Set tso = fso.OpenTextFile(fileName, FORREADING)
SQL = tso.ReadAll
'Create ADO instance'
connString = "DRIVER={SQL Server};SERVER=myserver;UID=MyName;PWD=notapassword; Database=favoriteDB"
Set connection = CreateObject("ADODB.Connection")
Set cmd = CreateObject("ADODB.Command")
connection.Open connString
cmd.ActiveConnection = connection
cmd.CommandText = SQL
cmd.CommandType = adCmdText
Set paramTotals = cmd.CreateParameter
With paramTotals
.value = "tot%"
.Name = "Param1"
End With
'The error occurs on the next line'
Set recordset = cmd.Execute
If recordset.EOF then
WScript.Echo "No Data Returned"
Else
Do Until recordset.EOF
WScript.Echo recordset.Fields.Item(0) ' & vbTab & recordset.Fields.Item(1)
recordset.MoveNext
Loop
End If
The SQL string that I use is fairly standard except I want to pass a parameter to it. It is something like this:
SELECT column1
FROM table1
WHERE column1 IS LIKE ?
I understand that ADO should replace the "?" with the parameter value I assign in the script. The problem I am seeing is that the Parameter object shows the correct value, but the command object's parameter field is null according to my debugger.
