A couple of methods pop into my head: 1) At the point the data is available, use a <dtml-in> to call an insert procedure once for every exam score. 2) Pass the list of (exam_score, student) in as a list of tuples to an sql query and use a <dtml-in> combined with a <dtml-var sql_delimiter> between each insert, such as: <dtml-in exam_scores> INSERT INTO EXAM_DB VALUES (<dtml-sqlvar score type=?>, <dtml-sqlvar student type=nb>) <dtml-unless sequence-end><dtml-var sql_delimiter></dtml-unless> </dtml-in> passing the data in in a usable format could be a challenge if you have two lists instead of a list of tuples. i don't know what the maximum size of an insert is - you may be better of with (1) if the insert size is large. HTH...

Hi Zopiis:
How i can build a DTML method for making multiple inserts in MySQL db. For example, inserting a exames scores for a class with 20 students.
My problem isn't make the sql query, but call the query for each pair (student_id, score).
I would like fetched the student_id and the student name from the db. How i can do it?
I find in this newsgroup some posts about the Product MySQLDA1.4. I have some queries for select integers and y d'ont have the related problems. For that i have changed the type INT(2), for example, to INT
If a is defined a INT(2)
for the query SELECT a FROM T1, the result is (23L)
i make
ALTER TABLE t1 CHANGE a a INT;
after this modifications for the query
SELECT a FROM T1, the result is (23)
It's Ok
Have a nice day. -- +------------------------------------------------------------- ---------+ | Jorge Magalhães Email: jmagalhaes@eng.uminho.pt | | Quinta do Calvário, bloco 14 Telemóvel: 966172200 | | 2º Direito Trás Fax: + 351 253 516007 | | 5400 Chaves Phone: + 351 276 333008 | | Portugal Email: magalhaes.jorge@netc.pt | +------------------------------------------------------------- ---------+
