[Zope-dev] ZSQL using LIKE operator

[Schmidt, Allen J.]

Yup...You're right. I found an item that had a single quote in it. I tried
it and the query blew up. then I added parts you suggest, and bingo...works
fine.

Thanks!

To get around another problem I noticed...
I have a keywords text field to search through everything in every category.
On the same page, I have links which pass on the category number to the ZSQL
method.
The keywords FORM uses a hidden category field which I set to =""  -- worked
fine.
But if I used the URL to jump right to the category listings, there was no
keyword to pass.
I just set an empty property named 'keywords' and then if the URL search is
used, keywords has a 'value'. 
I am sure there is a more elegant way to do this..but it works fine.

Thanks again guys!

Allen

SELECT * FROM table WHERE keywords LIKE '%<dtml-var name="my_var"
sql_quote>%'

would be a safer bet. Otherwise a value of my_var with a single quote in
it wouldn't work.
