Dear Zope Community,

=20

I am a zope newbie and enjoying it!  I am helping someone build a =
database for storing musical scores.

=20

I am using ZSQL and trying to figure out how to do the following:  I =
want to do some inserts then a SELECT and then run some DTML on the =
result to wrap the result with html.  This all needs to happen from one =
html form.

=20

The inserts and the select is on metadata pertaining to some an external =
file, which needs to get created during this process.  My ZSQL inserts =
the metadata into the database and creates an ID. I want to use this ID =
as the file name.  So far I have this:

=20

INSERT INTO titles (
id, title) VALUES (
   nextval('titleseq'),
  <dtml-sqlvar title type=3Dnb>
)

=20

<dtml-var sql_delimiter>

=20

INSERT INTO pieces(
id, primarytitle, category, subcategory, notes, lyrics, editor, =
lastupdated
) VALUES (
 nextval('pieceseq'),
 currval('titleseq'),
 <dtml-sqlvar category type=3Dint>,
 <dtml-sqlvar subcategory type=3Dint optional>,
 <dtml-sqlvar notes type=3Dnb optional>,
 <dtml-sqlvar lyrics type=3Dnb optional>,
 <dtml-sqlvar editor type=3Dint optional>,
 CURRENT_TIMESTAMP
)

=20

<dtml-var sql_delimiter>

=20

INSERT INTO piecetitles (
piece, title) VALUES (
 currval('pieceseq'),=20
 currval('titleseq')=20
)

=20

<dtml-var sql_delimiter>

=20

INSERT INTO scorefiles (
id, piece, filetype, filesize, lastupdated) VALUES (
 nextval('scorefileseq'),
 currval('pieceseq'),
 <dtml-sqlvar filetype type=3Dint optional>,
 <dtml-sqlvar category type=3Dint optional>,
 CURRENT_TIMESTAMP
)
<dtml-var sql_delimiter>

=20

SELECT currval('pieceseq')=20

=20

<dtml-var sql_delimiter>

=20

So next I want to take the ID - which is retrieved from the SELECT at =
the end - and use it to create an External File (with the External file =
product).

=20

I am stuck on writing the DTML that first inserts the metadata and then =
creates the External File finally returning the user a confirmation =
displaying the record they have entered.

 =20

Kind Regards,

=20
