The problem is that if the student does not have a username but has an ID number, then the first query returns NO ROWS and then the second query errors and the whole stored procedure fails.

So I've spent a fun time googling and binging but still haven't found a simple and complete example of getting a resultset from an Oracle stored procedure and displaying this in SQL Server Reporting Services (SSRS). Well "non-productive" more than "fun" as most of the examples on the net are either half-complete or par...

Need to be able to omit HTML tags in certain fields of a mySQL database.
What I'm trying to do is display a set of results (comparing various reports) in a table and then to color the backgrounds based on whether they are the fastest or slowest in the set. Something like:
Working principle
This site exists as a practical knowledge base built from real-world experience across systems, platforms, and technologies since 1999. Much of the content documents solutions, edge cases, and working patterns that were learned through investigation where documentation was incomplete or absent, and is shared to reduce the same friction for others.
