I've been going around and around on this. I've done scalar UDF's but this has me stumped.
I want to create a UDF that returns a text description from a reference file. In this case, supplier names are externally stored.
I currently do this with a join but it is a pain to repeat over & over. Also, the external file is multi-use and contains descriptions and other data for thousands of circumstances.
example: select CompanyNbr, ItemNbr, SupplierNbr, GetSupplierName(CompanyNbr, ItemNbr, SupplierNbr) from ItemMaster
I have yet to find a decent example showing this. Does anyone have an example? Also having trouble with long name versus specific name.
Thanks!
