Amazon goes after Microsoft’s SQL Server with Babelfish for Aurora PostgreSQL. What is interesting is that a direct port of SQL Server to PostgreSQL or Aurora PostgreSQL can be challenging due to incompatibilities in data types, and in functions. What is promised in Babelfish is that it will create a layer between standard SQL Server TSQL and PostgreSQL to be …
Occasionally I have come across the need to save the output from a query to a varchar value, for instance varchar(max). There are lots of ways to do this, could you use a cursor and just append to a string each loop through the cursor, but there is an easier way. Examples of a need to do this would be …
Posted 3/29/2020 — Edited 3/30/2020 to fix a couple of copy and paste errors, and to clarify a couple of items. Thanks Charlie for your suggestions.

After dinner, I start to do the dishes, while you set up the game. Rather than just doing the dishes that are dirty from our dinner, I decide to take all the dishes …
If you use the SQL Server maintenance plans to run DBCC Check DB, you are not allowed to include TempDB in your DBCC CheckDB sequence. For a while I was using maintenance plans, and ending up adding a separate job step to run TSQL to just check TempDB. Rather than using two different steps, the regular maintenance plan, and a …
Here is the solution provided by Patrick Flynn. Congratulations Patrick for being one of this weeks winners. I really liked this solution for a number of reasons, first it showed how to pull data from DBCC Page and actually convert it into rows and columns that could then be inserted back into a table. Secondly due to its use of …
The following are the steps that I went through to create a more difficult Database Corruption Challenge for Week 4. Here is how I built the database, nothing fancy, however I did add an extra FILEGROUP called [UserObjects].
