SQL Server string manipulation using T-SQL leaves lots to be desired. Many postings and complaints about T-SQL deal with strings, but there are ways to work with it. Author Eli Leiba brings us a way to split out portions of a string that contains tokens with a user defined function. Read on to see how this is accomplished and the code used to perform the splitting.

Dinesh is back with another article on user defined functions, giving some more great examples. If you haven't read the first one, definitely go back and read it first.

UDF's are useful if somewhat tricky. Dinesh uses a common scenario where you have a self referencing table (the common example is an employees table where each employee has a managerid that links to another employee in the same table) to illustrate how a UDF can make querying easier, how to use it as the basis of a computed column, and how to index that column.

The DMV, sys.dm_exec_cached_plans, contains rows for each cached plan on an instance. In Azure SQL Database, not every used has rights to every database, as there does exist an instance behind each database. How is security handled for this DMV in Azure?
