with discuss about security it is possible to query sql directly from dtml/zpt
with yourZSQLmethod like this:
sqlquery:string

It is few ways to go.
One is ODBC (and here are few ways to go too).
Second is TDS (FreeTDS)
Both I has some problems with parallel access and with big tables.
Third and the best one is the native access to MSSQL.
http://mail.zope.org/pipermail/zope/2004-May/149810.html
Note, that I was sometime mentioned 4k text limit which I could not get rid
off - it is limit of MSSQL server via TCP interface, which could be overriden
with sql command (right in ZSQL method)
set textsize 65535
select datetype_text from table...
I use it on production server with sybase ASE 11.9.2 (ASE is not running as
service, only libraries and config file(s?) are needed).
One caveat is only, that I could not get list of tables from database. But it
could be some kind of limits in MSSQL - Iam not msssql admin.

Re: [Zope-DB] Using s in ZSQL methods?
It is just because 'delete_this' is a string, not the list, or vice versa?
- Original Message -
From: "Ken Winter" <[EMAIL PROTECTED]>
To: "'Zope-DB List'"

Subject: [Zope-DB] Using s in ZSQL methods?
Here's the definition of a ZSQL method, "people_delete_by_id.zsql":
"
title: Method to delete People by ids given in a comma-separated list
connection_id: my_database
arguments:
id_list
delete from person
where person_id in ()
"
Here's the puzzle:
When I define and test this ZSQL method through the ZMI, passing it a string
such as "9765, 10058, 11333", it indeed deletes the rows with those values
on person_id.
BUT when I invoke the same ZSQL method from a Python script with the
following code:
"
p = context.REQUEST.get('delete_this')
if p:
s = ', '.join([str(x) for x in p])
context.people_delete_by_id(id_list=s)
"
...and with a REQUEST variable 'delete_this' that comes from this snippet of
a form in a page template:
"
...
...
"
...and with the same three person_ids (9765, 10058, 11333) the 4th line of
the Python script evokes an error:
"
KeyError: 'id_list'
"
The core idea is that the string id_list is passed into the ZSQL method,
where it is spliced into the "delete...where" clause via the ) to provide the list of person_ids to delete.
Here's the question:
WHY?
~ TIA
~ Ken
P.S. I know that rather than is an
unorthodox and apparently undocumented construct to use within a ZSQL
definition. But I need it because malformats the string.
And if doing this trick is a no-no, how come it works in the ZMI test but
not when called from Python? More importantly, how can I get it to work
from Python?

Re: [Zope-DB] Problem with feature
Try to set url_name as ['HI','RF'] and use property without datatype, like url_name ... And of course, look at ZopeBook. Personally I dont use sqltest nor sqlgroup because there are many caveats with queries to cooperate with other zope unfriendly SQL developers. I use dtml-in inside ZSQL method with parameters defined as above. - Original Message - From: "Ken Winter" <[EMAIL PROTECTED]> select organization_id, name, url_name, short_name from organization doesn't work properly when I give it "a sequence of values to test the condition against", which is what the "multiple" tag is supposed to allow according to http://www.plope.com/Books/2_7Edition/AppendixA.stx#1-15 . When I enter (for example) the string "HI, RF" (without the surrounding quotes) into the url_name field on the ZSQL method's ZMI Test tab, it returns no records and says that the SQL it generated was: select organization_id, name, url_name, short_name from organization where url_name = 'HI, RF' If I enter a series of integers such as "11530, 11531" (again, minus the "s) into the organization_id field, it returns the error message: Invalid integer value for organization_id Entering a single value into any of these fields works fine. I have tried various ways of quoting, delimiting, and otherwise punctuating my multiple-value arguments, to no avail. Is this problem just because the "multiple" feature doesn't work when tested in the ZMI? If so, can you tell me the correct way to type and format the multiple-valued arguments when calling the ZSQL method from Python or from a Page Template? b ___ Zope-DB mailing list Zope-DB@zope.org http://mail.zope.org/mailman/listinfo/zope-db
