The argument to "dtml-in" is a sequence of objects. "dtml-in" iterates over the objects. In each iteration, "dtml-in" exports the current objects attributes into the namespace. Thus, "seq", "vid", ... are probably attributes of your objects.

ZSQL methods do not perform acquisition, but will look at REQUEST, change it to. A minor clarification of terms: * *acquisition* acquires attributes/methods form containing objects or the context of the objects use * DTML methods usually are passed a *namespace* containing name-value bindings. This namespace contains many variables, REQUEST and its content, acquired attributes/methods, variables made available with dtml-with, dtml-let, dtml-in, dtml-tree... Z SQL methods do support acquisition. They are, however, not called (automatically) with the current namespace but only with the REQUEST object. Thus, they can automatically use only acquired attributes/methods and variables contained in REQUEST but not the variables defined in an enclosing DTML method (via with, let, in, tree ). Acquired attributes do not need tp be listed in the "Arguements" property of the Z SQL method, REQUEST variables have to.

[Zope] NESTED IN STATEMENTS AND PASSING VARIABLES in DTML
What is the DTML syntax for nested in statements. Here is an example. EXAMPLE 1: NO VARIABLE PASSING GOAL: loop 4 times and with each loop run the category_method and print out the results: dtml-in "1,2,3,4" dtml-in "category_method(id='1')" size=100 start=query_start id=dtml-var idseq=dtml-var seqvid=dtml-var vid /dtml-in /dtml-in WORKS! EXAMPLE 2: VARIABLE PASSING GOAL: Loop in the active_category_method and for each row run the category_method passing a new 'id' variable and print out the results. dtml-in "active_category_method()" dtml-in "category_method()" size=100 start=query_start id=dtml-var idseq=dtml-var seqvid=dtml-var vid /dtml-in /dtml-in ERROR -- ID is not being passed to "category_method()" Anyone have a solution out there? NOTE: active_category_method and category_method are SQL METHODS. Where 'id' is and SQL_VAR for category_method. Thanks in advance! Theodore E.

ZSQL methods do not perform acquisition, but will look at REQUEST, change it

dtml-in "active_category_method()"
dtml-call "REQUEST.set('id', id)"

If you have a lot of arguments that need to be captured, you can
build a DTML Method, say setup_category_method_parameters that
has these builds the REQUEST. Then your dtml can look like:
dtml-in "active_category_method()"
dtml-call setup_category_method_parameters
dtml-in "category_method()" size=100 start=query_start
id=dtml-var idseq=dtml-var seqvid=dtml-var vid

RE: [Zope] NESTED IN STATEMENTS AND PASSING VARIABLES in DTML
THANKS A TON!!!
I just found that the following solutions works also:
I think the only difference is the id is evaluated in the namespace variable
before invoking the SQL_METHOD
dtml-in "active_category_method()"
dtml-in "category_method(id=(_['id']))" size=100 start=query_start
id=dtml-var idseq=dtml-var seqvid=dtml-var vid
/dtml-in
/dtml-in
or
dtml-in "1,2,323,23,23"
dtml-in "category_method(id=(_['sequence_item']))" size=100
start=query_start
id=dtml-var idseq=dtml-var seqvid=dtml-var vid
/dtml-in
/dtml-in
Your point on the SQL_METHODS is a good one! I had no idea!

Re: [Zope] NESTED IN STATEMENTS AND PASSING VARIABLES in DTML
this should work too (untestet):
dtml-in "active_category_method()"
dtml-in "category_method(id=id)" size=100 start=query_start
id=dtml-var idseq=dtml-var seqvid=dtml-var vid
/dtml-in
/dtml-in
('id' var should be put on the namespace by 'active_category_method()'
and gets passed in to 'category_method()' (which, being a zsqlmethod,
wouldnt take a var from the namespace)
