Some of the options that come with SQuirreL that are talked about with regards to working together with Derby databases are:. After downloading SQuirreL, stick to the instructions on the installation page, squirrel. On my system, this command worked to launch the install wizard:. The wizard lets the location is chosen by you where you intend to install SQuirreL, also which plugins you desire to install. Observe that some of the Optional Plugins are considered Beta quality. After the installation is complete go to the directory where you installed SQuirreL and launch or double-click on Windows the squirrel-sql.

It will create a directory called when you first launch SQuirreL. This is where configuration settings and history are stored. The screen that is first appears in the desktop will show two windows - the Drivers and also the Aliases windows. If the container files for either among these drivers, derbyclient. Or even, a red 'X' will appear in front of these as shown below.

Find the Apache Derby Embedded option from the Drivers window and click the pencil symbol, that allows you to change the Selected Driver. We have to point to the positioning associated with the derby.

Click on the Extra Class Path tab, and then the Add button. Browse for this directory and select derby. Now, click the List Drivers button and the Class Name pulldown list shall be automatically populated. Find the Class Name of org. EmbeddedDriver from the list and click OK. Don't alter the Example URL in the Drivers screen because this is just a listing of available drivers, and does not express an association to a database that is specific.

That is what the Aliases screen is for. Now you need to be returned to the desktop that is main of and if the motorist had been added successfully, you'll see this message within the status window, with green highlighting;. Driver class org. EmbeddedDriver successfully registered for driver meaning: Apache Derby Embedded.

Additionally, there ought to be a blue check mark next to the Apache Derby Embedded listing in the Drivers screen now. Name the Alias something descriptive. For the driver, pull down the list to select Apache Derby Embedded.

A User Name and Password are not necessary to make an association utilizing the Derby that is embedded driver so I will not enter any values for this. Also, at this time I do not want to automatically logon or link at startup, and so I'll keep those containers unchecked. Test the text by clicking the Test button. Just click the Connect button to test. If all goes well the FirstDB database will be created in the directory where you launched SQuirreL from, and a popup package will let you know the text ended up being effective.

State OK to dismiss this screen, and from the next window click the OK button too. Close the next window instead of connecting, so we can set up the Derby Client driver first, before searching the database. The Derby Client driver is used with all the Derby system host, therefore we'll discuss the system server prior to configuring the customer driver. The Derby system host must be utilized in environments where numerous JVMs are linking to a single Derby database.

This configuration is required if other users will be connecting to the same database via other clients, for instance, ij or some other application in the context of using SQuirreL to browse a Derby database. Let's start the network server now, and create the database using ij prior to making the Alias with this database. Begin the Derby system host on your localhost.

If you do not know how to start the system server refer to the Derby guide , that also helps guide you to create up your environment to do so. This is the command I used to start the network server on my host with derbynet. In another command window, with derbyclient. Notice the difference in the URL when connecting to the network server versus when making an embedded Derby connection. Leave the network server and windows that are ij.

Click on the Extra Class Path tab then the Add button to browse to the derbyclient. The customer driver only contains one course of motorist, and so the Class Name category is populated aided by the value that is correct org. The correct value for the URL is: for my environment. This is what the values for my environment look like, right before clicking the Test button. A user password and name is required in the SQuirreL environment though it isn't needed for ij. Any value for the consumer password and name is going to do, but recognize that the consumer title sets the standard schema for the bond.

Note: if you'd like to need a specific username and password to connect to Derby, refer to this section of the Derby Developer's Guide, on configuring user authentication. Remember how we left our ij session active? When we clicked the test button, and later on when we connect to and browse the ClientDB database, we are taking advantage of the Derby Network Servers' ability to allow multiple client applications, running in different JVMs to connect to the same database. Click the Connect button to get in touch to your database and bring up the session window.

The session screen is shown below utilizing the Alias name listed as well as the username we associated with, in this full situation, as individual slc.

If we create some tables and insert data into our database before we explore the Objects tab, it will be more interesting. Select the tab that is SQL of session window and then make use of the folder symbol into the session screen to start a file. The image below programs exactly what the session screen looks like when I successfully executed most of the SQL into the file.

Given that we now have information in our ClientDB database, choose the items tab associated with the session window. The first thing you should do to start to see the tables you just created is to recharge the tree framework.

Find the schema folder which represents the user you connected because, within my instance here is the SLC folder. When connecting to a database in Derby, the default schema is the username you linked to. The five tables you simply created should appear. SQuirreL provides a lot of metadata about each database object. Look at some of the info provided by the different tabs and then click the tab that is content.

The image below shows exactly what the initial line in the CITIES table appears like it and then single-clicked in this column after I have right-clicked. By double-clicking the value in this column, several other options are available for updating or saving the value of this row's column, including importing and exporting values to a file or executing an command that is external.

Refer to the SQuirreL help system for a detailed explanation on these options. Also, exiting a session reverts the ability to edit the data to the setting which exists in the New Session Properties setting. Once there, look in the Output area, and the Table Contents setting. To make the output for the table default to Not Editable select Table.

To enable editing by default, select Editable Table. To set the default to enable editing in the existing session, click the farthest left icon on the menu bar and set the property there. A plethora of options is available when right-clicking one of the tables in the Objects tab. The available options can be grouped into these major categories:. In the version that is current of, V2.

In the 2. this may clear the current window that is SQL let us create a brand new apply for the insert statements we are going to create.

Now return to the Objects tab. This can immediately put you back the tab that is SQL. Save the file with an extension that is SQL. Every one of the rows in this dining table is eliminated in addition to any rows in other tables that are dependent on rows in the CITIES table.

The SQL tab becomes active. Click the X icon to close the file. Browse towards the file you created that contains the create table declaration. Then perform the SQL by clicking on the running man icon. The table should be recreated. Close this file and open the SQL file that contained the insert statements and run this file.
