MySQL Error codes and messages

Just a general rule with error messages: Usually they are not as good as they could be. But never the less read them carefully. Most of the time they tell you what you need to know...

And an other wisdom: Errors are really errors and they have to be solved. Warnings are warnings and you should investigate if they appear. Do not ignore both of them unless you have clearly understood what you are doing.

MyEnv für Multi-Datenbank Set-ups

Vor ein paar Wochen haben wir einem unserer Kunden unser MyEnv gezeigt. Er war sehr interessiert daran und hat uns geraten MyEnv einer breiten Öffentlichkeit bekannter zu machen. In Tat und Wahrheit ist das MyEnv bereits seit mehreren Jahren verfügbar und kann frei heruntergeladen werden...

MyEnv for MySQL Multi-Database set-ups

This week I showed one of my customers our MyEnv. He was very interested in it and suggested to make it known in public. In fact MyEnv is available for download already several years...

But I did not have the heart yet to announce it more publicly because it was not end user ready at all. So I used the weekend to make it nicer, consolidated some of the code, dropped old stuff etc. Now I think it is acceptable to use for public but not perfect.
