Export Excel Query To Multiple Text Files

I need to create a function which will take a objectname (a query or table) and a file name format

The objective is to export this query or table into multiple text files each with a maximum of 1000 lines per text file. These files are used as an input for SAP - the interface only takes a maximum of 1000 lines per file.

I am having three issues with the code below.

1. How do I split an excel query based on line numbers? Is there a way to get the equivalent of ROW_NUM in oracle ? Or do I have to loop through it and maintain a counter?
2. What is the best way to split the file ? Loop within loop? I need the files to be tab separated (no header required)
3.The rst.RecordCount is acting strange - when I pass a name of the query - the property returns the right no. of rows, however when I pass a any table name it only returns 1 - is this the expected behavior - or am I missing something

Code:
Function ExportAsText(strObjectName As String, strFileName As String) As Long
' Purpose: Export any given query, table to mutliple files each of certain length
' the no. of lines per text file is defined by the config parameter SAP UPLOAD, LINE LIMIT PER TEXT FILE
' in the LKUP_CONFIG database

Dim db As DAO.Database 'This database
