Simple SQL Server Functions to Solve Real-World Problems

Simple SQL Server Functions to Solve Real-World Problems. Article demonstrates the creative use of simple SQL Server functions, such as LEN and SUBSTRING (or REPLACE), in real-life scenario.


Today’s article comes from a scenario we experienced in practice some time ago. We managed a card transaction system referred to as Postilion, and we had to update the data in a column containing IP addresses as part of the string with a new IP address. This was necessary because the IP address of the server hosting the solution would typically change due to switchover or the data restore to a UAT environment.

The data about the server was stored in the databases, and there was no way to update the same from the application without going row by row. Thus, we had to come up with an efficient solution using the LEN and SUBSTRING (or REPLACE) SQL Server functions.
