USERS TO BLOB 


 

USERS TO BLOB ( users ) 
Parameter Type   Description
users  BLOB in BLOB that must contain users
in User accounts (encrypted)

The USERS TO BLOB command stores in the BLOB users the list of all user accounts and database groups created by the Aministrator.

Only the database Administrator or the Designer can execute this command. If another user tries to execute it, the command does nothing and a privilege error (-9949) is generated.

The generated BLOB is encrypted automatically and can only be read using the BLOB TO USERS command. You can store this BLOB in a file on your hard disk or in a field.

This command is the equivalent of recording groups and users from the Toolbar. The only difference is that it lets you store user accounts in a BLOB field and not just in a file.

This lets you keep a backup of users in the database data and, as such, implements a backup mechanism as well as a system to load users automatically when a database structure file is updated (information related to user accounts are stored by 4D in the database structure file).
