Either they're using an older version of MySQL OR they're not familiar with
creating contraints. I'm using 4.0.20-Max with 40+ InnoDB tables on Red Hat ES2
with CFMX 6.1 J2EE on JBoss 3.2.5 and all the RI is built into the database.
Using <cftransaction>, <cftry> and <cfcatch> I track all error messages from
the db. No transaction is committed when a foreign key constraint fails OR when
you try to enter a NULL in a NOT NULL column.
Since an empty string is different from a NULL value, I ensure that all
parameters sent to a query are converted to NULLs when the string is empty to
help enforce data integrity:
<cfif form.foo IS "">
<cfqueryparam value="" cfsqltype="CF_SQL_VARCHAR" null="Yes">
<cfelse>
<cfqueryparam value="#form.foo#" cfsqltype="CF_SQL_VARCHAR"
maxlength="20">
</cfif>
FWIW, I recently picked up some freelance work with PHP. Pretty much learned
what I needed in a couple of nights. I just thought to myself, "What would
Coldfusion do?" and looked up the similar functions in PHP. :D
My 2 cents.
