Delimited String Parsing Functions - Big Set
by Jesse Roberge - YeshuaAgapao@gmail.com
Update: Added robustness for NULL inputs and made it return no rows on blank inputs.
Feed it large strings of delimited horizontal data and it returns it back as a vertical table.
The Big function set supports more than 8000 character delimited strings, but the individual elements must be 8000 characters or less.
If you like performance you don't need to process delimited strings over 8000 characters, then use the basic delimiter function set instead of the Big delimiter function set.
Requires a table of numbers. These functions expect it to be called 'Counter' in the same database that you save these functions to.
Search for 'Counter table (table of numbers) setter-upper for SQL Server 2005' or Counter table (table of numbers) setter-upper for SQL Server 2000' if you need a script to set this up for you.
Works in both SQL Server 2000 and 2005.
Array Has array position index and value data is not casted.
Table No array position index and value data is not casted.
IntArray Has array position index and value data is casted to int.
IntTable No array position index and value data is casted to int.
In the Big2D delimiter function set, the table variants have some performance gain over the array variants, but are not very useful except in joins.
