Stored procedures (2)
I've got a tour on the web, searching for info and ideas, regarding the subject to implement some sort of stored procedure in mysql (remember Lets approach stored procedure thread ?) This was what I discovered - The Perl stored procedures (myperl project) in not a good idea at all, but, even if called poor man's stored procedure, I think that this project don't add, actually, stored procedure in the precise meamning of term. It add only a binding with Perl via UDF. It's a nice (and quite simple) hack. Dana Power, I've not take a look to _your_ hack, but I think this is the same approach. - I had searched everywhere the ANSI SQL3 directive... not luck. I only found a 1994 document where this directives were proposed It is quite incomprensile, though (like all standard doc I have read :) - I'm evalueting the IBM DB2 approach. Since the ol' COBOL days (rattles...) I remember the EXEC SQL ... END-EXEC commands embedded inside the COBOL as the host language. At compile time there was a cross-compile step the produced some code to get recompiled and finally linked and binded. This is also the (old?) informix approach, where SQL EXECs were embedded inside the C source, and then a cross-compile (or precompiler) make the dirty work, creating another C source that could finally be compiled and linked. But I don't know to have some (low skilled) SQL coders to be well skilled in some other language to write down a stored procedure. So here came my idea: use a SIMPLE language to write the logic of the stored procedure (no complex structures, definition and use of local variables, some test statement, error trapping, and of source free SQL coding), than use a precompiler to convert that source into the source of an UDF. At last, we had stored procedure written in a simple language, but compiled and used as UDFs. MySQL itself could then be used to store the packaging approach (as Oracle does), or other information regarding validation of the sp, last modification time, user... etc Just some thoughts Claudio Cicali mysql, database, tables - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Let's approach stored procedures
I think this is a little OT here, so after reading please indicate me where to talk about this subject. I'm a skilled programmer in C, C++ and others progr. lang. I have also a solid background in SQL and some RDMS (DB2, Oracle, SQLServer, and of course, Mysql). I'm going to attend a long period of holidays (finally) so, I thought: why don't try to implement stored procedures in mysql ? Now, on with the questions: I think that MySQL programmers had yet thinked on some way to implement sp, and I'd wish that someone say me: - No, dude it's impossible/too hard - No, dude, we are in the way to finish that by ourselves - No, dude, we never insert big patches in our official distribution branch, that does not belong to us Or, better, something more optimistic... I don't want to loose my time, in something that you know is impossible or too hard to get. Another question: At a first glance, I think Oracle PL/SQL is the best (afaik) programming language for sp, but, in the case we implement that language, should we go against some Oracle copytight infringment ?

Why would you want to do such a thing? Isn't SQL good enough? I'm just trying to figure out your reasoning here, besides the same argument used by the XML crowd of it's the latest/greatest do-all-be-all-end-all, so everyone should be using it type of nonsense. Nice question, overall. Answers (partial list): - it's cool - where I work, we have a HUGE database-driven web-application. A lot of our businness logic is implemented via stored procedures, that act as black boxes for the web-designers. Think of enterprise java beans. They are not nonsense or such. They are usefull. (I know, you can use ejb with JDBS and mysql..., but if you want to have some logic incapsualted, you should use some kind of component) - sp extends the RDBMS itself in its functionality. Think about some stupid check_fiscal_code() or insert_new_customer(). Web designers use the insert_new_customer, instead of using SQL directly. I think that there are others examples, but this is my point. - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Replication: Push by Master or Pop by Slaves ?
There is an issue that confuse me a bit, altough it is not important for an operational point of view: From the manual: The master server keeps a binary log of updates and an index file to binary logs to keep track of log rotation. The slave, upon connecting, informs the master where it left off since the last successfully propagated update, catches up on the updates, and then blocks and waits for the master to notify it of the new updates. So, it seems that is the master that pushes information to the slave(s) But I can also read: MySQL replication is based on the server keeping track of all changes to your database (updates, deletes, etc) in the binary log and the slave server(s) reading the saved queries from the master server's binary log so that the slave can execute the same queries on its copy of the data. Here, seems that are the slaves that pop data from master. So where is the truth ? Is the master that pushes or the slaves the pops ? Or it is a combination of the two ?
