To all Zopist,

(I am new to the list, and yes I am going through the archives for the answer, but haven't found it yet.)

I have a simple two field table in MySQL, "whowhat", that pulls a user

id

...

from one table, and a class code from another. (It tells you "who" has "what" classes)

I , being somewhat new to python & Zope, am having the darndest time trying to do a simple external method to do a count of how many times the class "so-and-so" is in the table. (That way, I know how many people have signed-up, and how close I am to the class max.) I have tried different searches. I have an SQL Method that does:

select * from whowhat

And I also have one that does:

... select * from whatwhat where classcode = <dtml-sqlvar class_name type=nb>

I've been trying to create an External Method, but I just can't seem to get it to work. (yes, in the Extentions directory)

I need to try to stay away from doing a "select count(classcode)..." in an SQL Method if I can.

Any help to this tormented soul would be greatly appreciated.

Let's say in Zope you have SQLMethod whowhat and SQLMethod whatwhat. In your external method you should simply be able to do:

def countWhoWhat(self): return len(self.whowhat())

def countWhatWhat(self, class): return len(self.whatwhat(class=class))

These should return the result count for each SQLMethod.

Greetings,

In my experience, to count the size of an array in ZOPE does not require an external method, simply "_.len(sqlQuery())". I use this myself in a few places.

I won't try to guess your reasons for not getting sql to count, but surely it would be by far the simplest way?

How about <dtml-in sqlQuery> <dtml-var sequence-lenght> </dtml-in> ? There also some more statistics over the columns. Please refer to the manual for more. Best regards Tino Wildenhain
