I have a lots of problem with the connection between eclipse EE and mySQL. I need to create a web application so I need a DB. I downloaded mySQL ( and mySQL workbench ).
I go to connect eclipse to DB but I can't do it.
This is the sequence that I do:
Please give me some information, I need to solve this . Thanks you guys.
So setting up a JDBC connection in Eclipse can be much easier than your approach. You can instead, try this:
Right click on your Java class in the Package Explorer in the Eclipse workspace.
Go down the list that appears until you find Build Path and click Add External Archives.
Find the jar file called mysql-connector-java-version number.jar and open it. This should connect your JDBC to Eclipse!
Hope this helps!

I am able to successfully get through the "Add New Data Source" steps in my C# project in Visual Studio, and get a connection to my MySQL database. However, when I then try to proceed (Note: AFTER it says my connection was successful, and I am able to select my Database name from the dropdown), I get this:
Researching this, it seems the usual suggestion is to re-download the ADO.NET Driver for MySQL (Connector/NET), which I did -- I downloaded and installed mysql-connector-net-8.0.21.msi. But I still get the same problem/error message.
Is it that I need to add one or more of the References depicted below to my project first?
If not, what am I missing to configure my project so that I can access the MySql database from my Visual Studio app?
UPDATE
This doesn't answer my question, so I won't do that, but I was able to solve my real problem, which was getting a connection to the database and inserting records into it.
I still get the same err msg I complain about above, but I guess it doesn't matter because, as I said, I successfully updated the database.
Here's how that happened:
While waiting for an answer to my question, I continued doing what I could. I found some code for inserting records using C# into MySql and added it to my code. Intellisense saw that I needed to install the MySql package:
...so I had it do just that. It automatically also added the necessary uses clause for me while it was at it.
All's well that ends swell.
To work with a MySql database you need to have a reference to the appropriate ADO driver. This driver known as MySql/Connector could be downloaded from the MySql site, or you can simply use the NuGet Package Manager right-clicking on your references node and then search for MySql.Data package.
After installing it into your project you should still add a using MySql.Data.MySqlClient; in all files when you interact with this library.
I work on Django using VS Code with MySQL database
i had to install mysqlclient to connect with my database
Try installing mysqlclient on terminal with command pip install mysqlclient on the directory you are working.
I am trying to make a simple java application that connects to database in Squirrel SQL which I use JDBC connector to connect to but I can't seem to pass making the database in Squirrel. I have my jdbc jar file in place as there is a blue tick indicating my driver is available but but I am not where I might be going wrong. Your shed of insight is highly appreciated. Thank you in advance. Below are pictures of what my setup looks like
Your database is a MySQL one. Instead of "jdbc" driver, use a MySQL one.
It is "MySQL Driver" in the Drivers menu. attach your jar file and then in the Aliases definition, use the MySQL Driver you just configured.
You should either use (or modify) a pre-existing RDBMS driver for MySQL or make your own and label it as a MySQL driver.
The key piece of information that may be missing is the qualified path to your RDBMS home directory. Squirrel needs to be able to find the jar file that contains the JDBC driver for the RDBMS product that you'll be using.
While I haven't set up Squirrel for MySQL, I have set it up for HSQLDB. In the "Extra Class Path" tab of the change driver dialog, I have added and entered the path to my hsqldb.jar file:
C:\App\Dev\Java\DB\hsqldb\2.2.9\lib\hsqldb.jar
This enables the service provider in the JDBC driver package to locate and load the particular JDBC driver for HSQLDB.
Just as a side note, every RDBMS has its own semantics for the connection URL. The one for HSQLDB is unique to it. The one for MySQL (according to the folks at SquirrelSQL) is:
jdbc:mysql://<hostname>[,<failoverhost>][<:3306>]/
<dbname>[?<param1>=<value1>][&<param2>=<value2>]
Good day, I'm currently new in working with databases. I downloaded an application called MySql Worckbench 5.2 CE because I saw that it has an easy way of creating and accessing databases. I'm now in the process of exporting the .sql. Whenever I go to the export tab which looks like this:
After I click on Start Export, it gives me this error:
I'm not sure what the error is cause I'm not familiar with MySql dump.. is there a way to resolve this? or use an alternative way. I'm also not familiar with using mysql from cmd (Windows) but if there is any suggestion or steps I can follow, it would be a great help.
Great and simple tutorial for MySQL Workbench.

Check out the Generating SQL section.
Still facing problem. ↓↓↓
Try installing MySQL Workbench on-default Windows directory.
I recommend using PhpMyAdmin

OR navicat? (not free)
or you can use Sequel Pro for mac (free)
I would like to extract and load data from mysql DB to another mysql DB without shutting down mysql in the process.
Tried to use the open source Talend community edition.
Used mysql input component, filled connection details which were tested to work.
Component could not connect to mysql and got the error:
Exception in component tMysqlOutput_1
java.lang.ClassNotFoundException: org.gjt.mm.mysql.Driver
though I added to eclipse project the jar: mysql-connector-java-5.0.8.jar
The mysql components in talend should absolutely work out of the box without the need to load any additional drivers. I'd say reinstall talend because something else is wrong.
To manually load your mysql connector, you can use the tLibraryLoad component.
Choose the jar file from the dropdown in the "Basic Settings". It should be there if it's been included in the project.
You can also pick a lib path in the component's advanced settings and add the import line below that.
Again, you certainly shouldn't need to do this for the mysql component. Talend comes with the drivers to connect to all databases that have components.
In fact I've copied those drivers to other programs that didn't come with them.
Good luck!
I am using Eclipse EE IDE and I am using the MySql Connector/J driver. How do I set up a properties file with all the information(DB URL, DBusername,etc) Also I see that you need a DBname and DBurl for the properties file, How do I determine/create this name for the database. I have already looked at the mysql website for this and am still having trouble, if somebody could pleasee help me I would appreciate it.
Solution: I was able to get it working through the plugin available with Eclipse, but I soon realized this limited me with the use of my Tomcat server, so I re organized my directories and set up Tomcat to use with my Eclipse and also be available to other resources.
Eclipse doesn't use a database for anything, so even if you would create a properties file, it would ignore it.
If you're using the DB plugin, then you can use the UI to create a connection for the database. The wizard will ask for all the informations and save them somewhere (probably not as a property file).
If you need the database in your own project, then you must define the format of the property file yourself, read it at startup, and use the information to create a datasource.
You should use phpMyAdmin, or MySQL GUI tools for MySQL setup and management
