Automating connection string to mysql?

I've just started to venture into some of my own php scripts that don't not follow the step by step beginner tutorials. What I can't seem to understand though is how do you get dreamweaver to automatically write the script to establish a database connection. I've connected to the database by going to DataBase -> Connect and inputting the settings in the dialogue box. DW acknowleges that the connection exists. But it doesn't automatically write the code to facilitate the connection, ie
$hostname_conntest = "my_hostname";
$database_conntest = "my_db";
$username_conntest = "my_username";
$password_conntest = "my_password"; etc..
I have to first create a record set to get this connection code written and then it seems to include about 25 more lines of code that don't seem necessary for what I'm trying to do, such as inserting magicquotes formula and so on.
does anyone know a simple one button solution to get the very basic connection settings to write to the source code of a new php doc.?
Thank you.

I usually just put the connection details in a stand alone file and use an include file in each page which needs a database connection
<?php include('database_connection.php'); ?>

Report Designer odbc connection string for data source using a parameter

I am using stand alone report designer 3 for the present and have a question/problem regarding the odbc connection string for MySQL when setting up the data-source
I need to be able to enter a parameter which is the database name i.e. BOE-201401 or say BOE-201312 etc from a list of databases the user can choose from.
at present the odbc connection string points to BOE-201402
the connection string is at present Dsn=Development Server for MYsql;description=MYSQL;server=ldndw01;database=BOE-201402;port=3306
my parameter has the name BOE_DATABASE
and in an expression it is as such
=Parameters!BOE_DATABASE.Value
I want to point the datasource for the report to the parameter value before the user sees the report.

Hi Leslie,
Based on your description, we want to design a report with a dynamic DataSource connection string. There are the basic steps below for your reference:
Create report with static database.
Change data source to report parameter.
Send new database connection string as a report parameter.
More detail information, please refer to the following blog: Dynamic Database in SSRS 2008.

Help with mySQL Connection string

Here is hoping someone can help & once I get it down I promise I'll post all my work on this list so some other newbie can benefit.
I'm simply trying to run a very very straightforward JDBC test with mySQL & I keep getting the "Server configuration denies access to data source" error. But before you tell me that I must simply look at what my mysql.db & mysql.user table allows - I'VE TRIED THAT. I realize that the error is probably there somewhere - but I can't see it.
I've tried connecting with 2 different accounts - the provided "root" & a user I created "deep" to 2 different databases the provided "test" & "testdb" which I created) . Here is what mysql says about the two different databases
mysql> select * from db;
Host | Db         | User |.......
-----+------------+-------
| %         | test    |       | ......
| %         | test\_% |     | ........
| localhost | testdb | deep |........Note that "root" should have access to "test" & deep@localhost should have access to "testdb" right?
So here are all the connection strings I have tried - all return the same error below
        Connection conn = DriverManager.getConnection(
            "jdbc:mysql://localhost:3306/test", "root", "mypass"
//            "jdbc:mysql://localhost:3306/testdb", "deep", "mypass"
//            "jdbc:mysql://localhost/testdb?user=deep&password=mypass"
//            "jdbc:mysql://localhost/testdb", "deep", "mypass"
//            "jdbc:mysql://localhost:3306/testdb?user=deep@localhost&password=mypass"
//            "jdbc:mysql://localhost:3306/testdb?user=deep&password=mypass"
//            "jdbc:mysql://localhost/testdb", "deep@localhost", "mypass"
//            "jdbc:mysql:///test", "root", "mypass"

you have your driver jar in Tomcat\common\lib?
if so, check your classpath, it could be that.

Can' t connect Java with MySQL

My goal is to connect Java with MySQL. I found many solutions on Internet, but I always get the same mistake:
SQLException: No suitable driver
SQLState: 08001
VendorError: 0MySQL works fine alone or with php.Only thing left me to think is that the installed versions are not compatible for this mysql-connector-java-5.0.4
I don't believe that could be a reason.
Installed versions are:
Apache Tomcat 5.5.20 Server
Apache HTTP Server 2.2.4
PHP 5.2.0
MySQL 5.2
jre 1.5.0_11
jdk1.5.0_11
Apache Tomacat JK2 connector Version: 1.2.20 File Name: mod_jk-apache-2.2.3.so
mysql-connector-java-5.0.4
I also set connector in class path: C:\mysql-connector-java-5.0.4;C:\mysql-connector-java-5.0.4\mysql-connector-java-5.0.4-bin.jar;C:\mysql-connector-java-5.0.4\src\com\mysql\jdbc
For installation I used manulas from:
http://apacheguide.org/jsp.php
http://doc.51windows.net/mysql/?url=/MySQL/ch23s03.html
Here is also a test code in java:
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
   public class Connect
       public static void main (String[] args)
           Connection conn = null;
           try {
    conn =
       DriverManager.getConnection("jdbc:mysql://localhost/first_test" +
                                   "user=monty&password=greatsqldb");
    // Do something with the Connection
} catch (SQLException ex) {
    // handle any errors
    System.out.println("SQLException: " + ex.getMessage());
    System.out.println("SQLState: " + ex.getSQLState());
    System.out.println("VendorError: " + ex.getErrorCode());
   }i'm desperate, please help or tell me someone who'll know the answer.
Thank You in advance

hey buddy .. it seems yr code is wrong .. in getconnection () method u should also specify the port ,which u r not doing ...
the default port for MySQL is 3306 ... see below i am giving you a sample code ... its working fine .. and dont forget to put the MySQL driver jar path in to classpath and also copy the jar into common/lib folder of your tomcat ....
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
public class MySQLConnectionTest {
     public static void main(String[] args) {
new MySQLConnectionTest().connTest();
public void connTest() {
          String tableName = "portfolio"; //change as per setting
          String hostName = "10.81.9.39"; // please change for the target database ip or hostname
          String dbPort = "3306"; //change if not using the default
          String dbName = "tradingsystem"; //change as per the given DB name
          String username = "root"; //change as per setting
          String password = "password"; //change as per setting
          System.out.println("before try");
          Double data=0.0;
     Double data1=0.0;
          try {
Class.forName("org.gjt.mm.mysql.Driver");
               System.out.println("before driver manager");
Connection conn = DriverManager.getConnection("jdbc:mysql://"+hostName+":"+dbPort+"/"+dbName, username, password);
String query1 = "select * from "+tableName+" where User_id='trader1' and Stock_Type='Equity'";
System.out.println("quesry1="+query1);
Statement stmt = conn.createStatement();
ResultSet rs1 = stmt.executeQuery(query1);
while(rs1.next())
     System.out.println("hiiiiii for rs1");
     System.out.println(rs1);
     Quantity=(Integer)rs1.getObject(5);
     MarketPrice=(Double) rs1.getObject(8);
     data=Quantity*MarketPrice;
     data1+=data;
     System.out.println("data1="+data1);
     i=0;
rs1.close();
stmt.close();
conn.close();
} catch (ClassNotFoundException e) {
e.printStackTrace(System.err);
} catch (SQLException e) {
e.printStackTrace(System.err);
i hope it will work for u...

I've solved the DW problem by changing the site folders from
'db' to 'wwwroot' e.g. 'C:\CFusionMX\db\' is now
'C:\CFusionMX\wwwroot\
However I'm now back to my original problem. I've lost my
mqysql connection in CF Adminstrator. Before I made these changes I
could connect to my mysql databases using the following settings:
JDBC URL: jdbc:mysql://localhost:3306/test
Driver Name: MySQL Connector J
using the following Java path and file:
C:\CFusionMX\wwwroot\WEB-INF\lib\mysql-connector-java-3.0.17-ga-bin.jar
Now these settings give me the following error:
"Connection verification failed for data source: javaserver
[]java.sql.SQLException: SQLException occurred in JDBCPool
while attempting to connect, please check your username, password,
URL, and other connectivity info.
The root cause was that: java.sql.SQLException: SQLException
occurred in JDBCPool while attempting to connect, please check your
username, password, URL, and other connectivity info"
Any suggestions on this would also be welcome.
Thanks again to everyone for their help.

The connection string for coded UI Data driven test using excel data source is not working

Hello,
I am using the visual studio 2012 coded UI test, i added the following connection strings to connect to an excel data source:
[DataSource("System.Data.Odbc", "Dsn=Excel Files;Driver={Microsoft Excel Driver (*.xls)};dbq=C:\\Users\\shaza.said.ITWORX\\Desktop\\Automation\\On-track Automation Framework\\On-track_Automation\\Automation data file.xls;defaultdir=.;driverid=790;maxbuffersize=2048;pagetimeout=5;readonly=true",

[DataSource("System.Data.Odbc", "Dsn=Excel Files;dbq=|DataDirectory|\\Automation data file.xls;defaultdir=C:\\Users\\shaza.said.ITWORX\\Desktop\\Automation\\On-track Automation Framework\\On-track_Automation\\Automation data file.xls;driverid=1046;maxbuffersize=2048;pagetimeout=5",
"Sheet1$", DataAccessMethod.Sequential), TestMethod]
But i get the following error:
"The unit test adapter failed to connect to the data source or to read the data. For more information on troubleshooting this error, see "Troubleshooting Data-Driven Unit Tests" (http://go.microsoft.com/fwlink/?LinkId=62412) in the MSDN Library.
Error details: ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified"
Thanks,

Thanks for Adrian's help.
Hi shaza,
From the error message, I suggest you can refer the Adrian's suggestion to check the date source connection string correctly.
In addition, you can refer the following about how to Create a Data-Driven Coded UI Test to check your issue:
http://msdn.microsoft.com/en-us/library/ee624082.aspx
Or you can also try to use a Configuration File to Define a Data Source for coded UI test.
For example:
<?xml
version="1.0"
encoding="utf-8"
?>
<configuration>
<configSections>
<section
name="microsoft.visualstudio.testtools"
type="Microsoft.VisualStudio.TestTools.UnitTesting.TestConfigurationSection,
Microsoft.VisualStudio.QualityTools.UnitTestFramework, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>
</configSections>
<connectionStrings>
<add
name="ExcelConn"
connectionString="Dsn=Excel Files;dbq=E:\Unit Test\AddClass\AddUnitTest\add.xlsx;defaultdir=.;
driverid=790; maxbuffersize=2048; pagetimeout=60;"
providerName="System.Data.Odbc"/>
<add
name="ExcelConn1"
connectionString="Dsn=Excel Files;dbq=E:\Unit Test\AddClass\AddUnitTest\sum.xlsx;defaultdir=.;
driverid=790;maxbuffersize=2048;pagetimeout=60"

</connectionStrings>
<microsoft.visualstudio.testtools>
<dataSources>
<add

connectionString="ExcelConn"
dataTableName="Addition$"
dataAccessMethod="Sequential"/>
<add

Cannot connect java to mysql server 2000

I donot have any user and pwd for the MYsql server, it is local host connection and window authentication is used.

eventhough it is local ,you may need to specify dns/localhost/ip with port number.
otherwise you can use myODBC driver which is freely available in mysql website. you can connect to the database using Data source Name, just like using any other ODBC connectivity.

If you have access to a copy of TimesTen 6.0 you can look in the AppServer Configuration Guide (appsrv.pdf) that was shipped with that release. This guide is currently being rewritten and so is not yet available for 7.0.
If you can't get hold of a copy, e-mail me at [email protected] and I'll send it to you.

Unable to connect JSP and MySQL

Hi, I am new to this forum
I've started developing web pages using JSP
I've the problem connecting JSP and MySQL database. I've created the page that retrive records from mysql table. But the connection fail to access to database it gives me this error:
org.apache.jasper.JasperException: Exception in JSP: /retreive_book.jsp:15
The code is:
12: <%
13: //Class.forName("com.mysql.jdbc.Driver").newInstance();
14: Class.forName("org.gjt.mm.mysql.Driver");
15: connection = DriverManager.getConnection(connectionURL,"","");
16: statement = connection.createStatement();
17: rs = statement.executeQuery("SELECT * FROM books_detail");
18: %>
And the connectionURL parameter has this value:
String connectionURL = "jdbc:mysql://localhost:3306/books?username=;password=";
root cause msg is:
java.sql.SQLException: Invalid authorization specification: Access denied for user 'nobody'@'localhost' (using password: NO)
Please can anyone help me. It is 3 days now trying to do that but not succeded yet

Hi
Yes It is true that my MySQl installation its username is root. So how should put that in the url. Cause I did that but it didn.t work
String connectionURL= "jdbc:mysql://localhost:3306/books?username=root;password=";
If I write in that manner is it correct for root username or should I put a single quote
Thanks

Sql / msql connection string

Hi
How can i do to connect to a sql or mysql database created in azure pack? the "View info" buttom show the connection string but, the server name is the listener name of my tenant cluster. Is there any option to connect like "publish profile?"
or something like that¨?

Hi,
We can find the server name, database name and user name from the connection string. We can connect to the database with the information provided by the connection string.
If you want to connect to the database by API, please refer to the link below,
SqlConnection.ConnectionString Property
http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlconnection.connectionstring(v=vs.110).aspx

Connect Forms to MySQL JDBC

Hi,
I need help connecting to a MySQL db through oracle reports using a jdbc connection.
I have downloaded the MySQL JDBC driver:mysql-connector-java-3.0.17-ga-bin.jar.
I can succesfully use it to connect if I write a simple java program. So I know the driver works.
I have set it in my classpath & edited the jdbcpds.conf file by adding the following:
<driver name = "mysql-merant"
sourceDatabase = "other"
subProtocol = "mysql"
connectString = "mainProtocol:subProtocol://databaseName"
class = "com.mysql.jdbc.Driver"
connection = "oracle.reports.plugin.datasource.jdbcpds.JDBCConnectionHandling">
</driver>
When I try to connect, I get the following error, ERR 62002 failed to connect to the data source.
What do I have to do to connect? Is there a way to directly give the connect string?
I can connect to an oracle DB using a the Oracle drivers no problem, why does forms not accept the MySQL driver? What can I do to make this work?
Any help would be appreciated.

With Reports 9i the mysql-connector-java doesn´t work for that. You don´t have to edit the jdbcpds.conf. mysql-merant doesn´t exist. Just download MyODBC conector and then stand up your database in your DSN system. Use the wizard to make a report, then use JDBC Query and using jdbc-odbc driver, fill the fields
then you have connected MySQL
very easy.
I hope this help you
