MySQL 5 fully backwards compatible??

Hello everybody

I guess the subject title pretty much sums it up. I`ve had some problems getting MySQL 5 to work with an application I`ve written using MySQL 4.1 and Visual Basic 6. I haven`t changed anything in my application so I expected it pretty much to work!!

Any ideas??

yes, i know of at least one application (can't recall which one it was, though) written with very sloppy SQL that throws errors in mysql 5

mysql 5 is more stringent with regard to enforcing standards

the scenario involves mixing table list syntax (e.g. FROM table1,table2,table3) with a LEFT OUTER JOIN

Here is a link to the changes between 4.x and 5.x - http://dev.mysql.com/doc/refman/5.0/...-from-4-1.html

Only items on the incompatible changes list should cause you problems and require corrections to your logic.
