EXAplus to DbVisualizer

Here are some best practices if you are moving from the old EXAplus client to DbVisualizer:

Keyboard Shortcuts

In EXAplus, the keyboard shortcuts for the statements start with CTRL+Enter. In DbVisualizer, it is CTLR+.

If you want to configure the shortcuts, see Changing Keyboard Shortcuts in DbVisualizer documentation.

Auto Complete

In EXAplus, to use the auto completion of table/column names you need to first type the schema name. In DbVisualizer, you can directly access the table or column name without the need to fully qualify the object. In DBVisualizer, if you are in the context of a schema, only the tables of that schema are shown in the auto completion. To learn more about the feature, see Auto Completion in DbVisualizer documentation.

You can also customize the behavior of the auto-completion from Tools > Tool Properties > SQL Commander > Auto Completion.

Creating LUA Scripts and UDFs

In DBVisualizer, LUA scripts / UDFs should be created as an SQL block. The start of the SQL Block is --/ and the end of the block is defined with /. For example:


return query([[select * from cat]])


By default, the keywords in DbVisualizer are displayed in uppercase. So if you open an existing LUA script, keywords are automatically transformed to uppercase and they won't work. To change this setting:

  1. Go to Tool Properties > Tools > SQL Formatting.
  2. Select Keep Case As is in the Case drop-down.

Additionally, see Executing Complex Statements.

Favorites or Bookmarks

In EXAplus, frequently used SQL Statements are stored in the Favorite tab.

In DBVisualizer, a similar feature is called Bookmarks. To learn more about the bookmarks feature, see Managing Frequently Used SQL in official DbVisualizer documentation.

EXAplus Commands

EXAplus commands like set autocommit off won't work in DbVisualizer. DbVisualizer has its own syntax for its client commands. The commands start with @. For example, @set autocommit off;.

To learn more about the client's commands, see Using Client-Side Commands in official DbVisualizer documentation.


Problem DbVisualizer has problem with delimiting Scripts.

Solution: To tell DbVisualizer that a part of a script should be handled as a single statement, you can insert an SQL block begin-identifier just before the block and an end-identifier after the block. The delimiter must be the only text on the line. The default begin-identifier consists of two dashes followed by a forward slash (--/) and for the End Identifier it is a single slash (/).

Problem: New Schema isn't visible in SQL Editor drop-down.

Solution: If the newly created schema is not visible in the SQL Editor drop-down, right click the connection and select Reconnect.

Problem: R scripts sent from a Windows OS using DbVisualizer are not executed. This issue occurs because DbVisualizer uses the platforms linefeed convention CRLF for Windows and LF for all other platforms.


  1. In DbVisualizer installation folder, open the file /resources/dbvis-custom.prefs in a text editor.
  2. Add dbvis.exasol.ReplaceCRLFwithLF=true as a new row and save the file.
  3. Restart DbVisualizer.
