Обсуждение: Connecting website with SQL-database.....
I've been looking on the internet for 2 hours for information how to connect my SQL database to my website. I didn't find what I was looking for, this is my problem............ I have got a form on my site, that can be filled in by visitors. I want the results automatically being written in my sql database, does anybody know how to do this???

For a very easy to use way of doing this, check out AOLserver -- while it does replace your existing webserver, it is fast and easy to use for PostgreSQL. If you are stuck with another webserver, you can probably use PHP, which is also easy to use, but not as scalable or fast as the AOLserver solution. And, you can always use a Perl CGI with either the Perl interface module distributed with the PostgreSQL distribution, or you can use the DBI/DBD modules, also from perl. If you've not written CGI scripts before, expect to speed more than 2 hours getting it to work. If you are comfortable with CGI scripts (or other web scripting), it shouldn't take very long to get the information you need from the PostgreSQL documentation and the PostgreSQL applications listing -- which I can't seem to locate at the moment. There is a users gallery on www.pgsql.com, but that's not the listing I remember.... -- Lamar Owen WGCR Internet Radio 1 Peter 4:11

I use embedded SQL for interface with database and POST method to get information from web. There are many free CGI scripts (C & Perl) on this website: http://cgi.resourceindex.com/Programs_and_Scripts/ I can share my programs but this is my first experience with CGI/Web/SQL, so programs are not elegant. -Rita -------------------------------------------------------- Margarita Barvinok University of Michigan System Administrator II Department of Biology brita@umich.edu ---------------------------------------------------------

It is one of the most powerful Web programming languages that is able to interface natively with dozens of types databases including PostgreSQL. The good part is that it is not tied to any Web server and it is Open Source. http://www.php.net/ If you want to use a DBMS independent interface with database try Metabase for PHP. Metabase not only provides database independence in the access but also in the installation of your database schemas (tables, fields, indexes, sequences). With a Metabase schema description language defined in a custom XML format, you are able to install your schemas portably without having to wonder exactly how. The neat part is that if you want later to change your database schema by adding/removing/changing/renaming tables/fields/indexes/sequences, all you need to do is to make the changes in your database schema description file. Then you only need to ask Metabase to upgrade it and it will issue the necessary SQL commands to alter your database accordingly without affecting any data that was stored after the database was installed for the first time or upgraded for the last time. Here you may find all the source code for Metabase with all the classes, for the schema parser, database manager, driver classes for different DBMS including PostgreSQL, example schemas and installation scripts, user manual and tutorial documents. http://phpclasses.UpperDesign.com/browse.html/package/20 Enjoy, Manuel Lemos Web Programming Components using PHP Classes.

As another alternative, Java Server Pages (http://www.javasoft.com/jsp) are great if you're into Java as you can embed the required (JDBC) code directly into your HTML (like ASP's but way way better IMHO) or alternatively package the logic into JavaBeans (or components) that can be called from your webpages. If you're ultra keen I can even post you some JSP's that demonstrate this...

Not that I recommend anything in particular for your specific situation, but it's always a good idea to get an idea of what's out there. cheers, --titus
I want to write a Java applet that retrieves/updates data in a psql database. I am running Apache and psql on a single OpenBSD server. I currently use PHP for dynamic pages; which has been fine up to now for presenting data, but I can see the day coming where some processing at the client side would be useful; so I want to take a closer look at java. I have been told by someone who knows little more than I do, that I need servlets to get at my data with java applets. When I go to the apache site, I see references to Jakarta, Tomcat, Java-Apache, JSERV and JSSI. But I couldn't find summaries that tell what these things are. Can someone tell me exactly which of the above components (and more?) I need to install to make this work? How do they fit together? Do I also need JDBC? Does JDBC require ODBC? Frank

Ok, I've not played with servlets (had no need) but here goes (and someone correct me if I'm wrong): Java-Apache is the name of the project to integrate Java with Apache. JSERV is a web server that embeds java into web pages which is processed on the server. This is not JavaScript, but similar to PHP or ASP. Not sure what JSSI is. I have heared of Jakarta & Tomcat, but thats all. > But I couldn't find summaries that tell what these things are. Can someone > tell me exactly which of the above components (and more?)

No. There are four types of JDBC driver, and ours is Type 4, which means its written in pure java, and will run anywhere.

This is not JavaScript, but similar to PHP or ASP. No. JServ is a servlet engine for Apache. It doesn't support JSP alone, and it's not compliant with last version of servlet API. Tomcat, a part of Jakarta project, is its successor : it's both a servlet (2.2 compliant) engine and a JSP (1.1) engine. > Not sure what JSSI is. I have heared of Jakarta & Tomcat, but thats all.

You'll need PostgreSQL for storing the data, JDBC driver to access them, Tomcat to process your servlets and JSP pages, Apache eventually if you also have plain HTML, as Tomcat is stand-alone capable. I don't know for JSSI, but for accessing data, this already largely enough. -- Guillaume Rousse Iremia - Universit� de la R�union Sleep doesn't exists. Just lack of cafeine.
The only thing I'd add to all of this is that applets can do your client-side processing for you if you like... your applet needs to open a URLConnection to a servlet on the webserver, and this way you can communicate via SSL, plain ol' TCP/IP, object input/output streams etc. But effectively the servlet you can think of like a CGI application running on the server. JDBC can also take place from the applet to the server, but there's issues between how IE's VM and Netscape's VM instantiate JDBC driver's (IE does not, as per usual, follow the standard).
