Hi Mark,
it is best to do the looping in python. consider the python script as
the proper place to process the form values taken from the request
variable. No problem to invoke multiple zsql method calls from within
this script. I even remember that all invoked zsql methods in one
requests belong to a transaction. If one fails, a rollback is done. Your
ZSQL connection has to be configured properly to use transactions and
your server has to support them as well.
Just in case you do not already found this - latest zope book and the
chapter about SQL connectivity

When I retrieve multiple values from a selection box, I need to create
a loop somewhere to insert the multiple values (rows) into a table. Is
there a way to do this within a ZSQL statement, or is it best to do
the looping in a Python script?
My specific example....
table 1 (Players) has information about players (i.e. team members for
a sports team). There is a primary key - playerID
table 2 (Seasons) has information about each season - primary key is
seasonID
table 3 (PlayerSeasons) has two columns - playerID and seasonID.
The form to crud a player has a combobox where one can select multiple
seasons for a player. When I do an add or update, I have to add one or
more rows to the PlayerSeasons table. Does this loop have to be in a
Python script, or can it be implemented in ZSQL? I looked at the
'multiple' keyword, but all the examples indicate that it apples to
sql tests, such as testing against a set of values. I can't seem to
find any examples where one is inserting multiple rows into a table.
Thanks!
Mark
