Console

OrientDB provides a Console Tool, which is a Java application that connects to and operates on OrientDB databases and Server instances.

Console Modes

There are two modes available to you, while executing commands through the OrientDB Console: interactive mode and batch mode.

Interactive Mode

By default, the Console starts in interactive mode. In this mode, the Console loads to an orientdb> prompt. From there you can execute commands and SQL statements as you might expect in any other database console.

You can launch the console in interactive mode by executing the console.sh for Linux OS systems or console.bat for Windows systems in the bin directory of your OrientDB installation. Note that running this file requires execution permissions.

$ cd $ORIENTDB_HOME/bin
$ ./console.sh

OrientDB console v.X.X.X (build 0) www.orientdb.com
Type 'HELP' to display all the commands supported.
Installing extensions for GREMLIN language v.X.X.X

orientdb>

From here, you can begin running SQL statements or commands. For a list of these commands, see commands.

Batch mode

When the Console runs in batch mode, it takes commands as arguments on the command-line or as a text file and executes the commands in that file in order. Use the same console.sh or console.bat file found in bin at the OrientDB installation directory.

  • Command-line: To execute commands in batch mode from the command line, pass the commands you want to run in a string, separated by a semicolon.

    $ $ORIENTDB_HOME/bin/console.sh "CONNECT REMOTE:localhost/demo;SELECT FROM Profile"
    
  • Script Commands: In addition to entering the commands as a string on the command-line, you can also save the commands to a text file as a semicolon-separated list.

    $ vim commands.txt
    
      CONNECT REMOTE:localhost/demo;SELECT FROM Profile
    
    $ $ORIENTDB_HOME/bin/console.sh commands.txt
    

Ignoring Errors

When running commands in batch mode, you can tell the console to ignore errors, allowing the script to continue the execution, with the ignoreErrors setting.

$ vim commands.txt

  SET ignoreErrors TRUE

Enabling Echo

Regardless of whether you call the commands as an argument or through a file, when you run console commands in batch mode, you may also need to display them as they execute. You can enable this feature using the echo setting, near the start of your commands list.

$ vim commands.txt

  SET echo TRUE

Enabling Date in prompt

Starting from v2.2.9, to enable the date in the prompt, set the variable promptDateFormat with the date format following the SimpleDateFormat specs.


orientdb {db=test1}> set promptDateFormat "yyy-MM-dd hh:mm:ss.sss"

orientdb {db=test1 (2016-08-26 09:34:12.012)}> 

Console commands

OrientDB implements a number of SQL statements and commands that are available through the Console. In the event that you need information while working in the console, you can access it using either the HELP or ? command.

Command Description
ALTER CLASS Changes the class schema
ALTER CLUSTER Changes the cluster attributes
ALTER DATABASE Changes the database attributes
ALTER PROPERTY Changes the class's property schema
BACKUP DATABASE Backup a database
BEGIN Begins a new transaction
BROWSE CLASS Browses all the records of a class
BROWSE CLUSTER Browses all the records of a cluster
CLASSES Displays all the configured classes

CREATE LINK Create a link reading a RDBMS JOIN
CREATE VERTEX Create a new vertex
DECLARE INTENT Declares an intent
DELETE Deletes a record from the database using the SQL syntax. To know more about the SQL syntax go here
DICTIONARY KEYS Displays all the keys in the database dictionary

RESTORE DATABASE Restore a database
SELECT Executes a SQL query against the database and display the results. To know more about the SQL syntax go here
REVOKE Revokes a permission to a user
SET Changes the value of a property
SLEEP Sleep for the time specified. Useful on scripts
TRAVERSE Traverse a graph of records
TRUNCATE CLASS Remove all the records of a class (by truncating all the underlying configured clusters)
TRUNCATE CLUSTER Remove all the records of a cluster
TRUNCATE RECORD Truncate a record you can't delete because it's corrupted
UPDATE Updates a record in the current database using the SQL syntax. To know more about the SQL syntax go here

EXIT Closes the console

Custom Commands

In addition to the commands implemented by OrientDB, you can also develop custom commands to extend features in your particular implementation. To do this, edit the OConsoleDatabaseApp class and add to it a new method. There's an auto-discovery system in place that adds the new method to the available commands. To provide a description of the command, use annotations. The command name must follow the Java code convention of separating words using camel-case.

For instance, consider a case in which you might want to add a MOVE CLUSTER command to the console:

@ConsoleCommand(description = "Move the physical location of cluster files")
public void moveCluster(
   @ConsoleParameter(name = "cluster-name", description = "The name or the id of the cluster to remove") String iClusterName,
   @ConsoleParameter(name = "target-path", description = "path of the new position where to move the cluster files") String iNewPath ) {

   checkCurrentDatabase(); // THE DB MUST BE OPENED

   System.out.println("Moving cluster '" + iClusterName + "' to path " + iNewPath + "...");
   }

Once you have this code in place, MOVE CLUSTER now appears in the listing of available commands shown by HELP.

orientdb> HELP

AVAILABLE COMMANDS:

 * alter class    Alter a class in the database schema
 * alter cluster  Alter class in the database schema
 ...                            ...
 * move cluster                 Move the physical location of cluster files
 ...                            ...
 * help                         Print this help
 * exit                         Close the console

orientdb> MOVE CLUSTER foo /temp

Moving cluster 'foo' to path /tmp...

In the event that you develop a custom command and find it especially useful in your deployment, you can contribute your code to the OrientDB Community!
