Squirrel Tool Download
Cheyenne Reinecke
Prerequisite, Java must be available:
Java is open source and can be downloaded from
SQuirreL will always run with the current LTS (Long Term Support) release of Java.
The minimum Java version required usually is the previous LTS release.
Installation of the SQuirreL SQL Client on Windows and Linux/Unix:
The SQuirreL SQL Client can be installed by the IzPack installer. Download the file squirrel-sql--standard.jarand execute it using the following command:
java -jar squirrel-sql--standard.jar when you properly installed Java.
or
\bin\java -jar squirrel-sql--standard.jar when you just unpacked the zip or tar.gz version of Java.
Note: On Linux/Unix replace backslashes (\) by slashes (/).
Make sure that you have write privileges to the directorythat you want to install into.
Note that some browsers may attempt to open thisfile rather than download it. In this case, right-click onthe download link and click your browser's equivalent of the"Save as..." menu item.
Installation of the SQuirreL SQL Client on MacOS:
On MacOS the preferable way to install the SQuirrel SQL Client is the MacOS X installer squirrel-sql--MACOSX-install.jar.
Starting the SQuirreL SQL Client:
On Windows, execute the file squirrel-sql.bat to run theapplication. On Linux/Unix and MacOS, the file is squirrel-sql.sh.
Trouble shooting:
When SQuirreL SQL doesn't start:
On Windows try to add the line
  set JAVA_HOME=
to the top of squirrel-sql.bat
On Linux/Unix or MacOS try to add the line
  export JAVA_HOME=
after the line
  #! /bin/sh
of squirrel-sql.sh
Scaling problems on high resolution screens:
Set the JVM (Java Virtual Machine) parameter
-Dsun.java2d.uiScale=
Example: -Dsun.java2d.uiScale=2.5
This can be done by editing squirrel-sql.bat on Windows and squirrel-sql.sh on Linux/Unix or MacOS
or by setting the SQUIRREL_SQL_OPTS variable before executing the start script.
SQuirreL's default language is English. If you would like to use SQuirreL in one of the translations availableyou need to check the desired optional translation package during the install process.If you want to use a new translation with an existing SQuirreL installation just download the translation jar filefrom the list below and drop it in your installation's lib directory. In case the translationmatches the language of your operating system all you need to do is restart SQuirreL.In case translation and operating system language do not match you must edit squirrel-sql.bator squirre-sql.sh file and add the following argument right behind the -Xmx256m argument of the start command:
-Duser.language=
All currently available translations are included in the install jar of the latest weekly snapshotor can be found in the sql12/squirrelsql-translations/src/main/resources/ subdirectory of our GIT repository which can be checked out using:
git clone git://git.code.sf.net/p/squirrel-sql/git squirrel-sql-git
The SQuirreL SQL Client is a database administration tool. It uses JDBC to allow users to explore and interact with databases via a JDBC driver. It provides an editor that offers code completion and syntax highlighting for standard SQL. It also provides a plugin architecture that allows plugin writers to modify much of the application's behavior to provide database-specific functionality or features that are database-independent. As this desktop application is written entirely in Java with Swing UI components, it should run on any platform that has a JVM.[3]

SQuirreL SQL Client is a useful tool for browsing and manipulating SQL databases via JDBC. This paper discusses setting up SQuirreL to access Derby databases via the Derby Embedded Driver and Client Drivers with the 10.1 version of Derby.
After downloading SQuirreL, follow the instructions on the installation page,squirrel.org/#installation, on how to install SQuirreL using the executable jar file. On my system,this command worked to launch the install wizard:
The wizard lets you choose the location where you wish to install SQuirreL,as well as which plugins you would like to install. I selected the Standardplugins because this paper will make use of the SQL Scripts standard plugin.Note that some of the Optional Plugins are considered Beta quality. After theinstallation is complete go to the directory where you installed SQuirreL andlaunch (or double-click on Windows) the squirrel-sql.bat file, or the squirrel-sql.sh file on Linux.
When you first launch SQuirreL it will create a directory called .squirrel-sql in your C:\Documents and Settings\ directory on Windows, or $HOME on Linux. This is where configuration settings and history are stored. The first screen that appears in the desktop will show two windows - the Drivers and the Aliases windows. The Drivers window willshow the Apache Derby Client and the Apache Derby Embedded drivers in thelist. If the jar files for either of these drivers, derbyclient.jar or derby.jar, are in your system CLASSPATH then they will have a blue check next to them.If not, a red 'X' will appear in front of them as shown below.
In another command window, with derbyclient.jar and derbytools.jar in my classpath, I issued this command to launch ij, and then created a database called ClientDB under my C:/derby_home/databases/ directory. Notice the differencein the URL when connecting to the network server versus when making anembedded Derby connection.
Before we explore the Objects tab, it will be more interestingif we create some tables and insert data into our database. Unzip the zip file, squirrel_derby.zip toa convenient location and locate the file tables_inserts.sql.Select the SQL tab of the session window and then use thefolder icon in the session window to Open a file. This allowsyou to browse to the tables_inserts.sql file and pastesthe output into the SQL editor area so we can run it. The CREATE TABLE statements included in thisfile are shown below (the inserts are omitted.)
Open squirrel-sql.bat in a text editor and navigate to the end of the file. One of the last lines should start with "start "SQuirreL SQL Client" - you have to change this line. Add -Duser.home=PathToStoreTheSquirrelConfigDir just after the -Xmx argument and ensure, that the new Argument is separated by a space from the others.
This is from the Squirrel-Manual, strangly enough, i couldn't find an online-source for it (only an outdated one), buts inside the squirrel installation folder, e.g. squirrel-sql-3.9.0/doc/quick_start.html
Database administration and reporting tools provide varying degrees of supportfor managing your database. Select a tool based on the type ofadministration and reporting that you need to do. For example, if you need toconnect to one database and issue a few SQL commands, considerusing the MySQL client.See Connecting MySQL Client Using IP Addresses.If you need to design or manage many databases simultaneously, thenuse one of the visual-based tools discussed here.
The southern flying squirrel (Glaucomys volans) is an important kleptoparasite of cavities excavated by the imperiled red-cockaded woodpecker (Dryobates borealis). Flying squirrel usurpation of cavities may affect woodpecker productivity, but current efforts to manage flying squirrels are costly and time consuming. We assessed whether capsaicin could deter flying squirrel use of woodpecker cavities on a site in southwest Georgia, USA. Twenty-nine cavity tree clusters received 4 treatments: capsaicin, water, air, and a control (no treatment). Only capsaicin both removed more flying squirrels from the cavity immediately after its application and decreased the probability of a flying squirrel occupying the cavity the next day. The data presented supports the potential of capsaicin to provide a more efficient way for dealing with this common kleptoparasite.
Anyone who's worked extensively with SQL databases knows the pain of writing out long queries over and over again, or having to work with different types of databases on different machines. Often, each type of database comes with its own front-end GUI tool for interacting with the data, multiplying the complexity even further.
SQuirreL SQL solves this issue by providing a single coherent interface for users to interact with many different databases, located on both local and remote computers. There's no need to learn multiple database administration tools just to have access to the information you want--SQuirreL SQL is all you need.
SQuirreL SQL is available from the project website ( ) as a JAR package file. The file name will take the form of "squirrel-sql-version-install.jar" or "squirrel-sql-version-MacOSX-install.jar" for Mac OS X systems, where version is the version of the SQuirreL SQL software.
HSQLDB, also called HyperSQL, is a convenient DBMS for application prototyping that does not require installation and is started automatically within CUBA Studio if the project has been configured to work with this DBMS. This section describes the way of connecting to HSQLDB with an external tool that allows working with DB schema and data directly via SQL.
