SQL compatibility with DB2

I have a series of queries in a coldfusion script that I originally used to create the tables in a SQLServer 2000 database. I now want to create the exact same set of tables in a DB2 data base on an AS400 machine. I would like you to look at each of the queries below and tell me what kind of syntax changes will need to be made to get the script to work with the DB2 databse or if it will work fine.
For those of you who aren't familiar with coldfusion, the SQL statements will be inbetween "<cfquery>" and "</cfquery>" like this:

<cfquery (tag attributes)>
SQL Statement goes here
</cfquery>

Here are the queries:
