Query Problem when converting from access to Mysql

Question

I am trying to get a small application to work with a mysql
db. The original
db is access, for some reason I am getting an error now that
the db has been
converted over to mysql. Any gurus out there spot the
problem. Here is the
query:
<cfquery name="getprevmonth"
username="#request.myDBUserName#"
password="#request.myDBPassword#"
datasource="#request.myDSN#">
SELECT cal_date,(day(cal_date)) AS theprevmonth
FROM jot_eventcal
WHERE (cal_date >=
#CreateDate(Year(prev_date),Month(prev_date),1)#) and
(cal_date <=
#CreateDate(Year(prev_date),Month(prev_date),DaysInMonth(prev_date))#)
</cfquery>
This query works fine when I test the application Locally, it
only messes up
when I test online. The error code is:
Syntax error or access violation: You have an error in your
SQL syntax.
Thanks for any assistance in advance...........and a happy
new year to you
all.

Answer 1

I don't know the answer but, it might be that using
createdate is not sufficient. Try wrapping that date into either a
cfqueryparam or createodbcdate.
Something else to bear in mind when switching db's is that
they don't all have the same functions. I don't use mySql so I
don't actually know, but I'd be checking the manual to make sure it
has a day function.
Not a syntax, but a potential logic error is that you are
using a function called day to create an alias called theprevmonth.
At the very least, it's misleading and might confuse you later
on.
