 sqlquery Plugin for DokuWiki

+Processing queries to databases and display results as a table.
 
-All documentation for this plugin can be found at
+This is a improved version which can connect to different hosts
+and databases. The defaults are set in the plugin configuration.
+Different types, hosts and databases can be set inside the tag:
+
+    <sql type=mysql host=myhost db=mydb>
+    SELECT foo FROM bar ORDER BY baz
+    <sql>
+
+For security reasons the credentials for database access are only
+stored in the main plugin configuration. At the moment there is
+only one user configurable so for access to multiple servers.
+So the user and password mast be the same across the servers.
+
+Based on sqlquery-plugin from George Pirogov, original documentation
+for that base plugin can be found at
