Re: [Zope] SQL delimiter?
You need to insert the following line between two SQL statements. Remember you can't use it with more than one SELECT. sql_delimiter is usefull only to separate more than one INSERT, UPDATE, DELETE.

Re: [Zope] Last day of Month
Use an External Method like this one.
# Perché non usare un metodo esterno?
from DateTime import Date
def lastDay(year,month):
try:
last = Date(year,month+1,1)-1
return last.day
except:
return 31

Re: [Zope] New user - couple of questions
Paolo Quaglia wrote: Hi to all,I'm a new Zope user/developer ... Zope has impressed me very much!Ihave a couple of questions.I want to build a new intranet site for my company using Zope, but:1. How can I import and use Python modules For example I want to use the function sleep(secs) that resides in the time module.I wrote this code: import time def hello(self): sleep(10) return "I'm Back!!" Better if you write this function like this: import time def hello(self): time.sleep(10) return "I'm Back!!" 1. give it a name, say pippo.py 2. then go back to your zope and add an External Method 3. put id=pluto 4. function name=hello 5. python module=pippo 6. save it If you want to try it create a DTML Document for example and put in it the the following command: and then view the DTML Document, after a while i.e. 10 secs you will see the message: I'm Back!! but when I call the external method bounded with the hello function an error occours!!1st. Have I to install the time module? - if yes where can I found it and where can I install it?2nd. How do I have to call the sleep function?2. I want to build an application that use the database transection to update rows.I use SQL server that support DB transactions.where can I build SQL transactions with Zope? do I have to build a ZSQL method with multiple SQL calls? .. for example:... If I am not mistaken, zope works all the time in transaction mode, then you don't need to expecify transactions at all. begin transaction update t_cliente set primaetichinterna = 'mia' commitAm I sure that the transaction will work (if another user use the same method at the same time)?How can I test if a transaction has been committed or aborted?Thanks VERY MUCH in advancePaolo QuagliaSitek Spa Italy Paolo Quaglia Information Technology Coordinator Sitek S.p.A.

Re: [Zope] how to get the created table names
There isn't a SQL standard command to show the tables in the database. Thus evry database has a different command to do such job. For example: DBMaker: to show TABLES: select * from SYSTABLE to show COLUMNS: SELECT COLUMN_NAME,TYPE_NAME,PRECISION FROM SYSCOLUMN WHERE TABLE_NAME='' MySQL: to show TABLES: SHOW TABLES to show COLUMNS: DESC PostreSQL: to show TABLES: select tablename from pg_tables where tablename not like 'pg_%' to show COLUMNS: SELECT a.attname, t.typname, CASE WHEN a.attlen > 0 THEN attlen ELSE a.atttypmod END as length FROM pg_class c, pg_attribute a, pg_type t WHERE c.relname = '' AND a.attnum > 0 AND a.attrelid = c.oid AND a.atttypid = t.oid I wrote a couple of ZSQL Methods to emulate a generic ISQL to query a database using the SQL language which shows the names of every table in the database and every column name, type and length of every table. If you want I can send you it.
