Question : SQL SPLIT Function Clarification

Hello Experts,

A previous problem that I had was creating a SPLIT table-valued function that took, basically, a record from a table called tblExtract which had tabs as the deliniator character. With assistance I was able to come up with a solution that would break up one row at a time into the respective fields and place it in a Table which was returned. I have uploaded the code for your review. Most of the fields were commented out to test the function.

This code appears to work, but seams stuck. The table I pull in from now has only one row for testing purposes. When I run this code in a stand-a-loan query I get an error indicating that I have called the function incorrectly. At that point I pass a string directly in the call.

What my end result is going to be is a @tmpTable that has each field that I can access. I want to write these fields to a new table called NewExtract. There are a number of fields in the @tmpTable, but right now I commented out all, but a few as you can see from the function code. This code should be relatively fast since there is only one call per row to the SPLIT function.

Code Snippet:
