[Zope] Newbie - parameterized query...

[fowlertrainer at anonym.hu]

Hello ,

  My problem is that:

  I have ZPT pages, and scripts. I want to check some infos with SQL
  query.

  This an example:

script:
-------
ss=context.REQUEST.SESSION
r=0
uusr=usr.lower()
result=context.LoginScripts.dbcheckUsrPwd(uusr,pwd)
if len(result)>0:
   r=1
   ss['userid']=row[0]
   ss["username"]=usr
   ss["full username"]=row[1]
return(r)

zsql:
-----
params: usr,pwd

select * from inst_prguser
where 
 webusr=<dtml-sqlvar usr type="string">
and 
 webpwd=<dtml-sqlvar pwd type="string">

The result is: "Missing input variable, usr".

I think this is wrong in zsql - it have wait for dtml-var.
But how to I do it in good way to the zsql get good parameters ?

Thanx.
