How do I install MonetDB/XQuery on my system?

The XQuery installation section gives download and installation instructions for various platforms with various degrees of detail. We recommend that you read the Quick Installation Guides for Windows and Linux section


I get the message !ERROR mapi_reconnect: connect: Connection refused, when trying to execute a statement using mclient.

Before you can start executing XQuery statements, you need to start the MonetDB Server. If you have a MonetDB Server running and mclient cannot connect, you might (in case of a Linux/Unix environment) have forgotten to start the MAPI Server module: pfstart(); and/or mapi_start();.


What XQuery Language is supported?

The XQuery language is very powerful, but it is sometimes difficult to grasp. If you have problems formulating your queries, please make sure that the functions you use are supported by MonetDB/XQuery. A detailed list of the supported please check this page.



Windows installer complains about DLLs

The older Window installers do not always remove MonetDB DLLs. Remove them manually from system32 before installing the new version. It concerns:

  1. libstream.dll
  2. libmutils.dll
  3. libMonetODBCs.dll
  4. libMonetODBC.dll
  5. libMapi.dll
