Before going any further, Rekall will attempt to create a special table when it tries to access a server database and finds that it do not exist (subject to checking with you that they should be created). The table, __RekallObjects, is used to store objects such as forms and reports when they are stored in a server database. ( Rekall does not create the __RekallObjects table for the !Files entry, since in this case it does not store objects in the database. ) .
Normally, you should allow Rekall to create these when it asks. One case that you might not want to do this is if you are using Rekall simply to look at (and maybe modify) data that is stored in existing tables, and where you will not be creating any forms or sthe like. In the event that Rekall cannot create the tables (maybe you have read-only access to the server database), it will warn you but continue. It you do not want Rekall to create this table (perhaps you only want to view tables in the database) and want to avoid the query, edit the database connection settings and select the Advanced tab. The setting Do not create rekall-specific tables can be checked to stop the table creation. The advanced tab is shown below.
