Wow. I'd stop listening to whomever it is that's telling you these 
stories. Really.

The difference between the MyISAM and InnoDB storage engines centers on 
InnoDB's excellent support for transactions (MyISAM has none), InnoDB's 
row versus full table locking with MyISAM, and general ACID compliance 
versus non-ACID compliance. But these features aren't related (as far as 
I have ever heard or seen in practice) to basic SQL syntax.

Check out the excellent MySQL documentation on-line that succinctly 
explains what MySQL can and cannot do today with each of the storage 
engines available to it:


General MySQL Features and Limitations
http://dev.mysql.com/doc/mysql/en/Features.html

MySQL SQL Syntax
http://dev.mysql.com/doc/mysql/en/SQL_Syntax.html

MySQL Table Types, their features and drawbacks
http://dev.mysql.com/doc/mysql/en/Table_types.html

etc.


This is by no means a "RTFM" but an encouragement to quickly find 
answers to many of these incorrect concepts others seem to have given 
you about MySQL. Read the documentation MySQL provides and you'll know 
first hand what the real problems are! :) But you'll also see what's 
useful, perhaps, and find something worthwhile.

HTH,

As an aside:
The freely accessible, transparent On-line documentation MySQL AB 
provides for its products is one of the telling traits of the company 
and its products as a whole. I personally have rarely seen such candor 
about one's own products in publicly accessible documentation. Helpful 
and refreshing.
