Each of them can own databases and also have various types of access to databases and database objects it doesn’t own. Assuming you are connected to a database as SYSDBA, you can add a user account as server, and the server makes sure that users only get the allowed type of access (if at all) to any objects within the database. As a relaxation of this rule, most Firebird configurations allow users to create a co-admin, a global mapping that gives any Windows account access to databases — but no special privileges — under the same name. This is done with the following command: create global mapping trusted_auth

Non-reserved keywords can be reserved words and keywords in the chapter Reserved Words and Keywords. 2.3. Identifiers All database objects have names, often called identifiers. Two types of names are valid as Chapter 2. SQL Language Structure variable-length string type: NATIONAL CHARACTER VARYING. 3.6. Binary Data Types BLOBs (Binary Large Objects) are complex structures used to store text and binary data of an undefined length, often very large

quit or exit.  The above technique, as demonstrated, works, but ideally databases and metadata objects should be created and maintained using data definition scripts. Chapter 9. Creating A Database variable is a named object that contains information used by one or more applications. They are global to their specific operating systems. The Firebird server recognises and uses certain environment Exceptions are database objects, like Tables, Views and Domains, and are part of the database’s metadata. They can be created, modified and dropped like all other Firebird objects using isql. In isql,

uncomment the IpcName parameter and set it to Global\FIREBIRD. Then restart the server. Note In Firebird 2.0.1 and up, Firebird automatically prepends Global\ to the IPCname if the connection fails because Each of them can own databases and also have various types of access to databases and database objects it doesn't own. Using gsec, you can add a user account as follows from the command line in the Firebird server, and the server makes sure that users only get the allowed type of access (if at all) to any objects within the database.

Administrator (on Windows systems, if Firebird runs as this user) needs also to have permissions to objects inside a database. For simplicity here, we will look at authenticating as SYSDBA using the password [utility]. You can use it for querying data, getting information about the metadata, creating database objects, running data definition scripts and much more. To get back to the command prompt type SQL>QUIT;# although, for your serious database definition work, you should cre- ate and maintain your metadata objects using data definition scripts. There is a complete chapter in the Using Firebird manual discussing

use the roles and privileges defined in that database to provide fine-grained access control to objects in that database. At no time does the user connecting to the database require direct access to by creating an SQL role name of SYSDBA and making sure it does not have access to the database objects. However it does not really solve the problem. The database file can be viewed with a hex viewer utility and the list of available user names discovered. (Discovering the owners of the database objects would be particularly useful.) Once known, these names can be added to the new server and used directly
