Two very useful open source SQL editors

Working in Business Intelligence (BI), I write and execute SQL statements every day. Actually it is more like every other minute. The SQL tool I use is thus very important to me. Over the years I have mainly stuck to SQuirreL SQL Client and wandered off every once in a while to check out different tools. One thing is for sure, no one tool will every have everything you need. At some point in time you have to make a choice based on the features most important to you.

Different database vendors will each have their own frontend specifically developed for their database. Oracle has SQL Developer and Sybase has Interactive SQL and so on. I would advise any budding BI practitioner to probably start with the tool supplied by the vendor. In most cases you will have less compatibility issues and the user can start writing and executing statements from the onset.

For those who use more than one database at a time and want to use the same SQL frontend I would recommend SQuirreL SQL Client or my current favourite tool of choice SQL Workbench\J not MySQL Workbench as these are two totally different products.

Over the next few weeks I will do some blog posts to highlight features I find useful when using SQL Workbench\J and SQuirreL SQL Client. Here are some features technical and not technical that both tools have in common that have led me to use these two tools.

    None technical reasons:
  • Open Source Software, both are free for commercial use and with the source code available are open to developers to debug or contribute features.
  • At the time of writing both are under active development with regular builds being released. Probably about a build (new version) a month apiece. I use the latest testing builds and don't stick to the stable versions. For the faint at heart stick to the stable release versions.
  • Active forums, where I was able to get a response to some questions I had on the applications.
  • Both applications run on different platforms due to the fact that both are written in Java. This allowed me to use both applications on Windows and Linux
  • Technical Reasons:

  • JDBC as connectivity means it is probably likely that you will be able to connect to any database. Most databases provide a JDBC driver.
  • Data explorer component from both products are quite customisable. It is possible to customise the schema's that display, customise the SQL statements generated such as the INSERT, UPDATE or DDL statements created.
  • Data import and export wizards for data in various formats including CSV, Microsoft Excel formats XLS and XLSX and OpenOffice formats ODF is possible using both tools. You are likely going to have to experiment here most specifically with date and null fields imports.
  • Both tools provide for customisations of how SQL history is handled, frequently used SQL statement, syntax highlighting, connection settings and session customisation to name a few.

Both SQL frontends are very capable and the learning curve for both is pretty steep. This can be expected given the complex nature of working with SQL and working on different databases. Most decent SQL tools have some complexity and instead of learning many different tools I decided to invest time into learning how to effectively use SQL Workbench\J and SQuirreL SQL Client.

I would urge you too to take a serious look at these two tools because you will not get much better generic SQL tools. The alternative which I trailed for a couple of years is using different tools for different databases. For MySQL one could use a tool like HeidiSQL that runs on Windows. For Oracle one could use as TOra which is an OSS frontend primarily focused on Oracle. This would mean learning a different tool for each database once uses. This is okay if you don't change databases often but I find myself using different databases regularly.

Don't be fooled by the dated screen shots on both web pages, these tools look much better. Here are the home pages of the two tools:

Over the next year I will be writing some blog posts with in-depth step by step instructions on how to use some use functions in both tools. Do I have a favourite out of these two, not really. SQuirreL SQL Client is the one I have been using the longest and I really like what I see with SQL Workbench\J.
