Advanced Query Tool

AQT is database client for windows, which can be used for querying a multitude of database management systems, e.g. EXASOL.

In addition to a database browser and the possibility to execute SQL statements, AQT offers (amongst other features) a query builder, a chart editor as well as the possibility to compare tables or rather resultsets from queries.


This tutorial is written for version 9.0.6. The latest version can be found on the AQT download website.
After downloading the zip file you have to unpack the archive and to start the installer. Afterwards you install the ODBC driver for EXASOL which can be found in our download area. Subsequently an ODBC data source has to be set up.

After starting AQT you have to select the ODBC data source and to log in. Having already entered the login data while creating the odbc data source, it is not necessary to enter username and password again.

Basic functions

After logging in, you find a 3-column view. Database schemas are displayed on the left, therein contained tables and views in the middle, and the corresponding columns on the right.

In the icon bar at the top you can reach the SQL editor by clicking on "SQL". There, you can write queries. An auto-completion and a query editor which generates queries with a few mouse clicks are available.

Clicking on "Run" the query is started and the result set appears.

Chart editor

Also, charts can be generated directly from SQL queries. The chart shown here was derived from the adjacent query. If you are in the SQL editor, with a click on "Chart" in the icon bar a graph belonging to the query can be created. The following settings are important:

  • "Data Columns: data for the Y-axis
  • "Label Column": labeling for the X-axis
  • "Chart Type": chart type (here: "bar")


				COUNT(*) count_customers,
				c_custkey < 200
		c_nationkey = n_nationkey
	count_customers DESC;

Query builder

The SQL query from the section "Basic functions" can also be created graphically with the query builder.
First, you click on "Query Builder" in the icon bar, selects the tables and views involved and then confirms with "OK".
After that, it is possible to formulate the join conditions using drag-and-drop. Then you chooses the values ​​to be selected clicking the corresponding checkboxes. In the sub-menus, join types, where conditions and other options can be set amongst others.
Clicking on "Run" in the icon bar, you send the query.

Comparing result sets

With AQT, two result sets can be compared. By clicking on "Compare" in the icon bar you can access the configuration menu, the result sets to be compared can be set and whether they should come directly from a query or from a table. It is also important to specify a "Unique Key". With "Generate Script" you can also generate SQL queries, which modifies one of the two tables so that it is equivalent to the other (with INSERT, UPDATE, and DELETE commands).

By clicking on "Compare", the compare view opens. There, lines are marked differently, depending on how they vary:

  • row only existing in left table
  • row only existing in right table
  • row existing in both tables, but with different values
  • row being the the same in both tables



AQT is particularly interesting when you want to work across databases, since a variety of manufacturers and products are supported. Because of its wide range of features you can use it for various tasks instead of using several tools.

AQT is available in a Standard Edition and Extended Edition, the latter containing mainly features for administration. A complete overview of the various features can be found here: http://advancedquerytool.com/features.html
