Question

I would like to know what are best practices for database queries. I am using C#, mysql database.

I have one application in which I had hardcoded all the database queries. Now client has modified database structure. So I have to again modify those queries and as all the queries are inside code, I need to test application, build it, create installer and do many more things related to deployment.

How to avoid such problems? Where shall we keep our queries? In some plain text file or inside app.config or somewhere else?

I will prefer queries to be configurable so that when something like this happens only configuration needs to be changed, no need to change code or executables.

We are not using stored procedures and no ORM framework also.

Thanks in Advance

Thank you everyone for your valuable inputs. I think in current situation the best I can do is to modify queries and try to emphasize on stored procedures from next time.

Thanks again.

We are not using stored procedures and no ORM framework also.

Those would have been your real options. If you’re not using them, you’re out of luck.

Maybe the best practice for you would be not technical but organizational. Set up a process regarding modification of the database.

• Changes to the database have to be discussed and agreed upon by all parties involved
• Every party involved should be notified about database changes in advance to have time to react to them
