SQL Errors and Database ProblemsLast updated: 28 September 2022
SQL Error 'db.#__docman_nodes' is not VIEW
While installing or upgrading DOCman, you might get a 1146 error which
JInstaller:: Install: SQL Error 'dbname.#__docman_nodes' is not VIEW.
This error means something didn’t go well with the installation and the view was not created correctly. You can easily resolve this with a few simple steps:
- Go to phpMyAdmin.
- Make sure that your database user has
- Look for the
#__docman_nodestable and delete it.
- Without uninstalling the existing version, re-install DOCman. This should create the missing view.
SQL Error 'db.#__docman_document_contents' doesn't exist
A 1146 error indicates that at least one database table is missing from your database. The error might look like one of these:
1146 - Internal Server Error
1146 Table ‘dbname.#__docman_document_contents' doesn't exist of the following query : SHOW INDEX FROM `#__docman_document_contents`
To resolve the issue, simply re-install DOCman without uninstalling it. The re-installation should create the missing database tables.
SQL Error SELECT list is not in GROUP BY clause
This error indicates that the
ONLY_FULL_GROUP_BY setting enabled is in MySQL. While this value is enabled by default in MySQL 5.7, the majority of web-hosts have disabled it (see: https://dev.mysql.com/doc/refman/5.7/en/group-by-handling.html).
Both Joomla and DOCman cannot run with the
ONLY_FULL_GROUP_BY setting enabled in MySQL and we suggest you or your host remove the value of it from your MySQL configuration's sql-mode value.
One of the working configurations that we're aware of is:
Joomla smart search problems when indexing large documents
You may encounter problems with indexing of large documents in Joomla smart search if your server's
MySQL MEMORY engine maximum size is too small for Joomla smart search indexing. There are two options to overcome these problems.
- Ask your hosting company increase the
- If you are not using smart search for DOCman you can disable the Smart Search - DOCman plugin
MYSQL VIEW error when importing the database for a Joomla 3.x site
When you are importing the database for a Joomla 3.x site, with DOCman installed, you might get the following error when your database user does not have
CREATE VIEW permissions, or when the
CREATE VIEW permissions are not properly configured.
SQL query: [Documentation] CREATE ALGORITHM=UNDEFINED DEFINER=`xxxxxxxxxxx`@`xx.xxx.xxx.x/xxx.xxx.xxx.x` SQL SECURITY DEFINER VIEW `jos_docman_file_counts` AS select `jos_docman_documents`.`storage_path` AS `storage_path`,count(0) AS `count` from `jos_docman_documents` where (`jos_docman_documents`.`storage_type` = 'file') group by `jos_docman_documents`.`storage_path` MySQL said: [Documentation] #1227 - Access denied; you need (at least one of) the SUPER privilege(s) for this operation
You can fix this error in one of two ways:
- Ask your hosting company to allow your database user to perform
- If your database user already has
CREATE VIEWpermissions then you will have to manually tweak the SQL query. Change the query from
CREATE ALGORITHM=UNDEFINED DEFINER=xxxxxxxxxxx
SQL SECURITY DEFINER VIEW
so that you end up with something like this:
CREATE VIEW `jos_docman_file_counts` AS select `jos_docman_documents`.`storage_path` AS `storage_path`,count(0) AS `count` from `jos_docman_documents` where (`jos_docman_documents`.`storage_type` = 'file') group by `jos_docman_documents`.`storage_path`
Unknown storage engine 'MEMORY'
When publishing documents if you encounter the following error, it means that your database does not have the
MEMORY engine enabled:
Unknown storage engine 'MEMORY' .../libraries/vendor/joomla/database/src/Mysqli/MysqliStatement.php:435
MEMORY engine is required by Joomla's
com_finder component. You need to either enable it in your database or disable Joomla's
com_finder component, for more information please see: https://forum.joomla.org/viewtopic.php?t=990519
