[Zope] ZSQLMethod conditional insert
Hi This is probably an FAQ but I haven't been able to find and answer. I need a counter for a certain CMFType and want to store the hits in a MySQL database not to fill up the ZODB. I've checked to two suggestions below but they both use two ZSQLMethods first to check if the URL is already in the table, then to do the actual update or insert. http://www.zope.org/Members/element/Simple_SQL_Page_Counter http://zopelabs.com/cookbook/991116439 I'd like to be able to do that just in one ZSQLMethod for efficiency but I cant seem to figure out a way of doing it. The table is very simple: CREATE TABLE mostread ( path varchar(255) NOT NULL default '', num bigint(20) NOT NULL default '0', dt datetime NOT NULL default '-00-00 00:00:00', PRIMARY KEY (path) ) For now my ZSQLMethod get the argument path which is a relative URL and it looks like this: select @lastval:=num from mostread where dtml-sqltest path type=string dtml-var sql_delimiter update mostread set [EMAIL PROTECTED], dt=now() where dtml-sqltest path type=string; /dtml-if But that naturally only works if there is already a record containing path. What I want to do is something like this (pseudo-code): select @lastval:=num from mostread where dtml-sqltest path type=string dtml-var sql_delimiter dtml-if sequence-length 0 update mostread set [EMAIL PROTECTED], dt=now() where dtml-sqltest path type=string; dtml-else insert into mostread(path, num, dt) values(dtml-sqlvar path type=string, 1, now()) /dtml-if Is there a way of doing this or should I just create that extra ZSQLMethod? -- Med venlig hilsen Thomas Olsen http://www.headnet.dk ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

Hi David On Wednesday den 27. July 2005 23:50, David Pratt wrote: Hi Thomas. I would say postgres is better for this sort of thing. In postgres, you can write a function in plpgsql or other function language (there is also a python function language) that you install in postgres. In any case once you write it and then call it - it is executed in a single transaction. You are only left with selecting the function in your zsql from your script. I would prefer postgres too but it is decided to use MySQL in the project... It is hard to comment on the method you have sketched out not knowing what arguments you are passing into the method. You have identified path but I see others that you haven't discussed so don't really know where you plan on getting them from. Well path is actually the only argument passed to the method. select @lastval:=num is a (I think) MySQL specific way of assigning values to local variables. I could probably use a sub-select or something but my SQL is a bit rusty ;-) Regards, David On Wednesday, July 27, 2005, at 03:22 PM, Thomas Olsen wrote: Hi This is probably an FAQ but I haven't been able to find and answer.
