I'll try.
I have a list of records from a single sql table that are viewed by the browser using sql SELECT. I would like to go down and 'check' or mark certain specific records. Then, for only the records that are 'checked', I would like to use sql UPDATE to replace the a value for one of the variables. The value replaced for that variable would be the same for all of the marked records.
nutshell version use a multi-select box on the form, use zope coercion to convert it to a list. on the form processing page, convert the list to a comma separated string in your select do a update table_name var_name = value where pk in (value_comma_string) hth kapil

I hope someone has an example or suggestion.
Using Znolk, I SELECT from a table and the list is viewed. However, I would like to choose certain records (mark them from the viewed list) and then change a variable of only the marked records to a single new value. The new and old variable values are finite, they could come from a pull down list.
So the idea would be to show the list from SELECT, but have an pull-down menu of new values at the top of the page that should be replaced for the variable to edit. The user would choose the new value from the pull-down and then go down the page and mark each record for which that value would be UPDATEed in the table
Once this is done the values would be passed back to sql and UPDATE used to replace the old values. I'm not quite sure how to do this either. Do you have a loop, where inside the loop the UPDATE is goes through each marked record, or do you loop inside the
UPDATE tablename set variable=newvalue where ----loop here with or's------
Any suggestions or similar examples would be appreciated.
