Use same report with different MySQL database

I am using CR2008 with MySQL 5.1.
I have a report that works with one of the tables (T1) in a MySQL database (DB1). I have another MySQL database (DB2) with the same table name and structure, except that the data has been updated.
I want to use the same report, but just ask CR2008 to now use DB2 and T1.
Try as I may (using Set Data Source Location...), but I'm not getting anything to work.
I looked for a previous thread on this, but was unsuccessful.
Thanks for any help.
David

Thank you for your helpful response. What I am really asking is this -- when there is a CR2008 report based on db1, table1, and you want to use the SAME report with an identical table in a DIFFERENT database (db2, table1), can I easily use the same report? Or, do I have to generate another version of the report?
Thank you again.

Linking Azure website with Remote mysql database in Cpanel

I am creating an azure website eg calvynlee.azurewebsites.net
In my hosting cpanel account, I create a mysql db & user, in order to link the azure website with this mysql db, I had place a "%" in the remote mysql section.
It works, but when I remove the % from the remote mysql section. Azure website unable show error connection with my database.
Question:
Understand that placing % is allow all remote connection to my database. For security purpose, placing % is not recommended, and placing the website IP address is the most suitable practice.
Unfortunately, I place the website IP (by ping the website and obtain the IP) in remote mysql section is not working.
My cpanel service provider mention that the IP I obtain is not the right IP, there will be another host sever IP
What is the actual IP address I should put? and How to find this right IP?

Hi,
Based on your description, your mysql db is created in cpanel, and want to let the azure website connect with this db, I don't familar with cpanel, in general way the azure website request may be stopped by something, such as firewall etc.., as far as I
know, the azure Hybrid Connections may meet your requirement, you can connect a website on Microsoft Azure to any on-premises resource that uses a static TCP port, such as SQL Server, MySQL, HTTP Web APIs, Mobile Services, and most custom Web Services, refer
to
http://azure.microsoft.com/en-us/documentation/articles/web-sites-hybrid-connection-get-started/ for more details, hope this helps, if not, please feel free to let me know.

Need Help with my frist database

I am developing a Java application locally with a very simple database.
Where do I begin when I want to make a database? I know SQL but never done a connection to database.
I can do my tables with a database tool program (does Sun have such a program for design of database?)
When I am trying different database tools, they want me to connect to the db-server? What does it mean? How do I choose a db-server (this is not a web application).
Thank you for some advice to push me in the right direction...
Kia

I by myself (the writer of this topic), found a great website with instructions in details for newbie like me. I am recommending it to everyone who is doing its first database:
http://www.developer.com/java/data/article.php/3417381
Questions I made before are all answered here, as:
Getting things up and running
As a minimum, getting up and running with MySQL and JDBC involves at least the following steps:
Download and install the appropriate release of the MySQL database server software (several different releases are available).
Download and install the MySQL Connector/J -- for connecting to a MySQL database server from Java.
Download and install the documentation for the MySQL database server.
Download and install the documentation for the Connector, which is a separate documentation package from the database server documentation.
Write and test one or more JDBC programs that will act as a database administrator, creating one or more users and possibly one or more databases on the database server. (I will show you three different ways to accomplish this.)
Write and test a JDBC program that will log in as a user and manipulate data stored in one of those databases.
Nice yeee... This was what I needed...

Connecting a Local Java Program with a Mysql Database Hosted on the Interne

I need help. I want to connect a java program running on local user computers to read and write to a mysql database hosted in my domain by an internet service provider.
What code do i use?
How do i connect?

http://java.sun.com/developer/onlineTraining/Database/JDBC20Intro/JDBC20.html
You'll ned to downloda the JDBC driver file from MySQL, and check their docs for the format of the connection URL.

Need help with loading MySQL results into a query

Hello, I need some help figuring out why my tree component
isn't being populated with my MySQL results.
I have a table of categories:
ParentID - CategoryID - Name
Every top-level category has a ParentID of 0 (zero). I'm
using php and a recursive function to build an array of nested
results, then passing those results back to Flex, making those
results a new ArrayCollection, then assigning that to the
dataProvider of the tree.
Result: my tree component is blank
Suspicion: it has to be a way with how my array is being
formed in PHP. If I play around with how it is formed I can get
some odd results in the tree, so I know it's not a problem with the
data being passed back to Flex.
I am attaching the PHP code used to form the array, and the
output of the array being created

Why not just build xml and send it back? Xml is hierarchical
by nature.
However, if you want to stick with the nested ACs then are
you using a labelFunction() with your tree? The node values are in
different properties, so you can't just set labelField.

Help with embedded MYSQL

Hello,
I try to create a desktop appliaction with netbeans and I want to save my data to a database.I try it with a mysql server and all is ok.But I want to try it with a embedded mysql server(like mysql.jar).I archive this before a year with h2db embedded drivers, but now I want to archive this with mysql.
So my question is can I do this?If yes, what files must to download and import into my project?and what about jdbc url?
Thank you.

mysql.jar represents the MySQL JDBC driver, not the embedded database. MySQL doesn't offer an Java based database. MySQL is a real database server which you need to install separately at the same machine. If you want a Java database, then you need to look for for example Hypersonic (which is the h2db you used), JavaDB (ships with JDK6) or Cloudspace.

Help with structuring SQL databases for multiple photo galleries..help!?!

Hello all,
As a new PHP/SQL developer I have found great technical assistance from both this forum and from David Powers and his wonderful books. I am at a crucial point in my web development and although I believe I know which direction I need to go, I am still uncertain and so I appeal to you all for your help, especially David Powers.
The website I am building is one which will house many photo galleries. I was able to successfully modify the code provided in David Powers’ book ‘php Solutions’ so that I got the photo galleries constructed and working in the manner I desired.
That being said, a person browsing my website will be presented with a link to see the photo galleries. There will be five (5) categories in which the photos will be separated, all based on specific styles. Now that I have the galleries working, I need to know how to structure things so that I can create a page, like a TOC (table o’ contents) that shows all photo galleries by displaying a thumbnail image or two along with the description. Perhaps I’ll limit the TOC page to only show the latest 25 galleries, arranged with the most current always on top.
The way I have my galleries set up, I have a separate database for each one, containing the photo filenames and other relevant data. To build my TOC structure, should I have an overall database that contains each gallery database filename along with category? This is where I have no idea what I’m doing so if my question sounds vague, please understand I have no other idea how to ask.
The site will grow to the point of having hundreds, if not thousands of photo galleries. I simply want to know how to (organize them) or otherwise allow me to build a method to display them in a TOC page or pages.
I know this is a bit dodgy, but with some info and questions back from you, I feel confident that I should be able to get my point across.
Lastly, I am still developing this site locally, so I have no links to provide (though I feel that shouldn’t be necessary right now).
Many sincere thanks to you all in advance,
wordman

bregent,
I'm chewing this over in my head, reading up on DB's in 'phpSolutions' and I think that things are slowly materializing.
Here is the structure of the website that I have planned:
MAIN PAGE
User is presented with a link on the main page to select photo galleries (other links are also present). Clicking the link takes them to the Category Page.
CATEGORY PAGE
On this page, the User will then have 5 choices based on categories (photo style). CLicking any of these 5 links will take them to respective TOC pages.
TOC PAGE
On this page, the user is greeted with a vertical list of galleries or photosets; one to three thumbs on the left, a small block of descriptive text on the right (ideally containing date/time info to show how recent the gallery is). Newest galleries appear at the top. Eventually, when there are tens or hundreds of galleries in any given catrgory, I'll need to adopt a method for breaking up the qualntity in groups (we can pick 20 for example) that can be scrolled through using a small navbar. This will keep the TOC Pages from getting endlessly long and avoid endless scrolling. User selects a gallery on this page to view.
THUMBNAIL PAGE
On choosing a gallery, a thumbnail page is generated (I have this working already)
IMAGE PAGE
On selecting any thumbnail in the grid, the user is taken to the full-sized photo with a navbar and photo counter at the top. Navlinks allow forward and back, a link to the first image, a link to the last image and one link back to the thumbnail page. (I have this working already).
I provide this info in an effort to help understand the basic structure of my site. The description above is as close to a step-by-step illustration as possible.
Thank you!
Sincerely,
wordman

Help with updating a database while in cfloop

Greetings. I'm having some difficulties in updating a
database using cfquery inside of a cfloop.
Background:
I've got a text file that I need to interpret, line for line,
and then update an existing database with information from that
text file. For example, the text file might say
jdoe~103 Anywhere St.~East Nowhere~New Jersey~05784~
asmith~8963 North St.~Crabapple Cove~Maine~01390~
(etc...you get the idea)
So, I use a CFFILE to read the file, and then calculate the
number of lines (records to be updated in the database) using
listlen / 5 (in this example). From there, I:
<cfloop index="record" from="1" to "#numberoflines#">
<cfloop index="field" from="1" to "5">
<cfset position = ((record - 1) * 5) + field>
<cfelseif field EQ 1>
<cfset form.username =
ListGetAt(newcontents,position,"~")>
<cfelseif field EQ 2>
<cfset form.street =
ListGetAt(newcontents,position,"~")>
(etc...through EQ 5)
</cfloop>
<cfquery name="updatedatabase"
datasource="clientlist">
UPDATE clients
SET
Street= '#form.street#',
(etc)
WHERE email = '#form.username#'
</cfquery>
</cfloop>
The problem I am having is that it updates the very first
record in the set of records to update, but then it does not update
any subsequent records.
Why?
Sorry if the code is crude. Is there a better way of doing
this? If so, great detail would be helpful :) Relatively new at
this.

Better yet, that file has to come from somewhere. Is there a
way you can update your db instead of generating a file in the
first place?
The file starts as an output generated by a web user (an
administrator on the software) which creates a text file containing
email addresses, one per line. An external process which I have no
control over takes that file and generates another file containing
information about each of those e-mail addresses (last name, first
name, etc) one per line. I can't change that process. So, I'm left
with an external text file that I need to parse and then put into
the database...all through a web interface. The goal here is that
an administrator of the software, who does not have direct access
to the database, can (using cold fusion processing) update the
database with new information on each e-mail address without my
intervention.

Help with building a database portlet (reference_path) issues

I'm attempting to create a Provider Portlet based on the Database Provider example. The goal of the portlet is to
dynamically display a Portal Report based upon a session storage variable. The session storage variable is set in another portlet on the same page. My portlet is named DYNAMIC_RPT.
I'm able to display the report from within my database portlet by calling the report's .show procedure.
But, my problem is this: The reference_path is generated for my database portlet, for example 131_DYNAMIC_RPT_123123, so when I click the NEXT button on the report, the page is refreshed but the report is still on page 1.
I think the problem is that my portlet needs to internally determine what the reference_path SHOULD BE for the report I'm trying to display, and use it in the associated provider API's.
If I could call the API which is generating the reference_path I could then pass an appropriate reference_path. I would need to be able to dynamically regenerate the reference_path when ever the session variable changes. Is this possible ?
Also, when I'm building the p_arg_names, and p_arg_values whould I ONLY extract the argument(parms) which are associated with the p_reference_path of the portlet report currenttly being displayed ?
Also is there a session storage variable which contains the current PAGE ID and TAB ID. I'm extracting it form the PAGE_URL but it's very messy code.
Thanks in advance for your help !!

Hi,
you can do what you want with LiveCycle, and it might help you to look at this reference as it shows how to work with data ( it does depend how your data is stored)
http://help.adobe.com/en_US/livecycle/9.0/designerHelp/index.htm?content=000006.htmlhttp://help.adobe.com/en_US/livecycle/9.0/designerHelp/index.htm?content=000006.html
If you data does not change very often then I would recommend just using an XML file to store the data and then use thebinding ability with possible some JavaScript to create the solution you would like.
Hope this helps

Need serious help with JSP + JDBC/Database connection

Hey all,
I have to build an assignment using JSP pages. I am still pretty new and only learning through trial and error. I understand a bit now, and I have managed to get a bit done for it.
I am having the most trouble with a Login Screen. The requirements are that the a form in a webpage has Username/Number and Password, the user clicks Login, and thats about it. The values for the username/number and password NEED to come from the database and I cannot manage to do this. The thing I have done is basically hardcode the values into the SQL statement in the .jsp file. This works, but only for that one user.
I need it so it checks the username/number and password entered by the user, checks the database to see if they are in it, and if so, give access. I seriously am stuck and have no idea on what to do.
I dont even know if I have made these JSP pages correct for starters, I can send them out if someone is willing to look/help.
I have setup 3 other forms required for the assignment and they are reading data from the db and displaying within tables, I need to do this with non-hardcoded values aswell. Im pretty sure I need to use for example 'SELECT .... FROM .... WHERE username= +usrnm' (a variable instead of username="john" , this is hardcoded), I just CANNOT figure out how to go about it.
Its hard to explain through here so I hope I gave enough info. A friend of mine gave some psuedocode i should use to make it, it seems ok to follow, its just I do not know enough to do it. He suggested:
get the username and pass from the env vars
open the db
make an sql (eg SELECT user, pass FROM users WHERE user = envuser)
index.jsp points to login.jsp
login.jsp get the vars you put into index.jsp
opened the db
is the query returns nothing - then the user is wrong
OR if the passwords dont match
- redirect back to index.jsp
if it does match
- set up a session
- redirect to mainmenu.jsp
Anyway, thanks for any help you can give.
-Aaron

Hi,
Try this... it may help you...
mainMenu.jsp
<html>
<body>
<form method="POST" action="login.jsp">
Username: <input type="text" name="cust_no">
<p>
Password: <input type="password" name="password">
<p>
<input type="submit" value="LOGIN">
</form>
</body>
</html>
login.jsp
<%@ page import="java.io.*, java.sql.*"%>
<html>
<body>
<%
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection connection = DriverManager.getConnection("jdbc:odbc:rocky");
Statement statement = connection.createStatement();
String query = "SELECT cust_no, password FROM customers WHERE cust_no='";
query += request.getParameter("cust_no") + "' AND password='";
query += request.getParameter("password") + "';";
ResultSet resSum = statement.executeQuery(query);
if (request.getParameter("cust_no").equalsIgnoreCase(resSum.getString("cust_no") && request.getParameter("password").equalsIgnoreCase(resSum.getString("password"))
%>
<h2>You are logged in!</h2>
<%
else
%>
<h2>You better check your username and password!</h2>
<%
}catch (ClassNotFoundException cnfe){
System.err.println(cnfe);
}catch (SQLException ex ){
System.err.println( ex);
}catch (Exception er){
er.printStackTrace();
%>
</body>
</html>
I didn't check the code that I wrote. So you may have to fix some part of it. Also this may not be the best solution, but it will help you to understand the process easily.
The more efficient method is to check whether the result set returned from the database is null or not.... I hope you got the idea... Good luck!

Help with com.mysql.jdbc.Driver

Hi all
I am new to working with java. I am working off of my laptop (pc -vista) and
am trying to connect to a database on a server I have, mac osx 10.x.
First question: I would install com.mysql.jdbc.Driver on the same server as
the MySql server correct?
Second and more important question: I have multiple pages
printed out on installing this driver but I just cannot follow it. I am not
very good in terminal(mac) and the install seems terminal based.
Can someone please try to explain to me in laymen terms what needs to
be done?
thanks alot

MarcusYes, you can move the jar into the ext directory if you wish. How are you running your java application? What are you typing/clicking on?

Help with DW, MySQL and PHP

Hi,
I've created a simple login system using dw8. When a user logs into the system, he can see all the support incidents create by him. This is done with a simple mysql query and a dynamic table is populated with the incident IDs.
However, I would like to make each incident ID which is returned clickable. So when the user clicks on any of the incident ID which is returned, it should redirect the user to a page which displays some information about that incident.
Can someone please tell me how I can get this done.
Thanks in advance

First thing you are going to need to do is to read up on sessions.
http://www.tizag.com/phpT/phpsessions.php
Sessions are important because if this information is sensitive (by calling it "incidentID" I get this impression) then you need to ensure that the user is logged in throughout the process. So when the user is logged in you need to store data that you might need to access quickly like the userid and the user's group ID. Then once you write the values to the session (which DW should allow you to do) you can call the variables from the superglobal $_SESSION. This way you have data to ensure that the user is who they say they are and did pass the login.
Without seeing your table design (for the database) I can tell you the logic of what's going on, but if you need more specifics about your example you will need to post more information. What you need to do is when you print the results just print them with a link around it, so:
echo "<a href='detailpage.php?incidentid=$_POST[incidentID]'>$_POST[incidentID]</a>";
That's just the simplest solution. I'd recommend having your loop print in a table or other structured format and loop the printing in that manner. Then on the following detail page you should call the user's session so that anyone on Google can't just go to "detailpage.php?incidentID=###" and get into the pages without logging in.

Help with creating a database instance and populating it

the project given to me is to create a database and populate it in berkeley DB. use that as the backend to the Oracle Business Intelligence tool and run some tests.
with other databases like oracle, sybase and teradata, there were user interfaces both GUI and CLI to create a database. they provides sql interfaces for DDL/DML execution to create objects and populate them. basically these utilities helped me do my project successfully. but in berkeley DB i find very minimal utilities and they dont correspond to those provided by other databases.
is there an interface in berkeley db for sql execution
in general how do i create database and populate data in berkeley db
thanks
[email protected]

Hi Prasanna,
is there an interface in berkeley db for sql executionNo, Berkeley DB does not provide an SQL interface. It is a library that can be used to store and retrieve key/data pairs in a database. The Berkeley DB reference guide is a good place to look if you want to get an overview of Berkeley DB functionality:
http://www.oracle.com/technology/documentation/berkeley-db/db/ref/toc.html
in general how do i create database and populate data in Berkeley db You generally need to write code to do that. There are a number of programming language bindings provided for Berkeley DB, including a Perl binding. So you can write your testing code in the Perl scripting language if that suits you.
If you intend to measure performance I would recommend using the C or C++ APIs to build your application. The best way to become familiar with using Berkeley DB is with the Getting started guides found here:
http://www.oracle.com/technology/documentation/berkeley-db/db/index.html
Or by familiarizing yourself with the example applications that are shipped with the source distribution.

Need Help with IMG+PHP Database+Selective Display

The problem is really a lot simpler than I made it sounds to
be, though I fear the answer might be vice versa.
I need to have pictures appear when they exist. That's all.
Here is where I am at:
I have created a php database for a news announcement page.
In that database, I have a column named "img" whose default value
is "null"
Whenever I actually have a picture corrosponding to a
particular news, the "img" column will change to the file name of
that image, which I will then extract.
So basically... if news A, img = null... no picture. news B
img = b... then yes picture. very simple concept for database.
Here's what I can't do.
When I read the database from DW, how can I make it so that
when it reads a "null" it won't insert a picture and vice versa? I
figure it definitely has to do with the "if" statement (duh...)
I know how to make text do that effect...
<? if $row_data['text'] != null
echo("i have data");
?>
but how do i do it with an image? I tried putting the image
tag to replace the entire "echo" line, but that's apparently not
how you do it. I tried putting it inside "echo", but that doesn't
seem to be it either.
also, as a premise, all pictures are associated with only 1
particular news.
which i wrote something similar to this:
<img src="<?php echo $row_data['img']; ?>.jpg"
width="200" height="200" />
Um, basically... I need THAT to fit into the IF statement. So
thanks in advance.

if (!is_null($row_data['img']))
echo '<img src="',$row_data['img'],'.jpg" width="200"
height="200" />';
Let's break that down into the following:
echo '<img src="' ;
echo $row_data['img'] ;
echo '.jpg" width="200" height="200" />' ;
When you string multiple echoes together use a comma between
them,. so now
we have:
echo '<img src="',$row_data['img'],'.jpg" width="200"
height="200" />';
(You may also use a period, but my understanding is the
period is less
efficient.)
I only have single quotes in my PHP statements. The double
quotes you see
are part of what will be the rendered HTML.
You may generally use the single quote or double quote
interchangeably with
few exceptions such as having double quotes as part of the
text or vice
versa among others. You can probably escape the characters
too, but lets
keep this simple for now.
If I misspoke I am sure Micha will be sure to correct me.
IMO The best thing to do is learn by trial and error, and
your best resource
on the net for PHP is probably the php website. www.php.net
