I had modified the code in ADOdb5 to define the constants that were giving the errors and I was able to get rid of the error messages but the application was unable to return a recordset, so I removed the mods.
Well, I got it working correctly on an earlier version of Yii last night after posted the topic. So I believe it is an issue between Yii and ADOdb5 and Zend Apache 2.
I installed XAMPP and mySQL and everything works just as it should.
SO, Thanks for the suggestion but I’ll be closing this topic.
