This section is for advanced administrators who are familiar with the SQL database language. The ‘SQL Query' field on this page takes a full (and properly written) SQL query to be performed against your In-portal database. Clicking ‘Save' will run the query and display the results on the next page, where you will get a chance to edit the query and run it again. Please use extreme caution when using this function, because it does not provide any safeguards for the data, otherwise available in the rest of the administrative console. You can easily erase, or corrupt your In-portal data with a wrong query. It is also possible to cause the MySQL server to “freeze”, or stop responding, in extreme cases. We recommend making a full database backup (see section 5.2.6.5 ) before running any UPDATE, DELETE, INSERT, ALTER or DROP queries.
