\d Meta-Commands

Vertica supports a number of \d commands, which return information on different categories of database objects. For a full list, see \d Reference below.

Syntax

Unless otherwise noted, \d commands generally conform to the following syntax:

\dCommand [ [schema.]pattern ]

Arguments

You can supply most \d commands with a string pattern argument, which filters the results that the command returns. The pattern can optionally be qualified by a schema name.

schema

Valid for most \d commands, specifies to return only database objects in schema. For example, the following \dp command obtains privileges information for all V_MONITOR tables that contain the string resource:

=> \dp V_MONITOR.*resource*
                Access privileges for database "dbadmin"
 Grantee | Grantor | Privileges |  Schema   |            Name
---------+---------+------------+-----------+----------------------------
 public  | dbadmin | SELECT     | v_monitor | resource_rejections
 public  | dbadmin | SELECT     | v_monitor | disk_resource_rejections
 public  | dbadmin | SELECT     | v_monitor | resource_usage
 public  | dbadmin | SELECT     | v_monitor | resource_acquisitions
 public  | dbadmin | SELECT     | v_monitor | resource_rejection_details
 public  | dbadmin | SELECT     | v_monitor | resource_pool_move
 public  | dbadmin | SELECT     | v_monitor | host_resources
 public  | dbadmin | SELECT     | v_monitor | node_resources
 public  | dbadmin | SELECT     | v_monitor | resource_queues
 public  | dbadmin | SELECT     | v_monitor | resource_pool_status
(10 rows)
pattern

Returns only the database objects that match the specified string. Pattern strings can include one or more of two wildcards:

Wildcard character Represents‚Ķ
* (asterisk) Zero or more characters
? (question mark) Any single character

For example, the following \dt command returns tables that start with the string store:

=> \dt store*
                     List of tables
 Schema |       Name        | Kind  |  Owner  | Comment
--------+-------------------+-------+---------+---------
 public | store_orders      | table | dbadmin |
 public | store_orders_2018 | table | dbadmin |
 public | store_overseas    | table | dbadmin |
 store  | store_dimension   | table | dbadmin |
 store  | store_orders_fact | table | dbadmin |
 store  | store_sales_fact  | table | dbadmin |
(6 rows)

\d Reference

Command Description
\d

Unqualified by a pattern argument, returns all tables with their schema names, owners, and comments. If qualified by a pattern argument, \d returns all matching tables and all columns in each table, with details about each column, such as data type, size, and default value.

\df Returns all function names, the function return data type, and the function argument data type. Also returns the procedure names and arguments for all procedures that are available to the user.
\dj Returns all projections showing the schema, projection name, owner, and node. The returned rows include superprojections, live aggregate projections, Top-K projections, and projections with expressions.
\dn Returns the schema names and schema owner.
\dp Returns a summary of privileges on all objects in system table V_CATALOG.GRANTS: grantee, grantor, privileges, schema, and object name (equivalent to \z).
\dS

Unqualified by a pattern argument, returns all V_CATALOG and V_MONITOR system tables. To obtain system tables for just one schema, qualify the command with the schema name, as follows:

\dS { V_CATALOG | V_MONITOR }.*
\ds Returns sequences and their parameters.
\dT

Returns all data types that Vertica supports.

\dT returns no results if qualified with a pattern argument.

\dt Unqualified by a pattern argument, returns the same information as an unqualified \d command. If qualified by a pattern argument, \dt returns matching tables with the same level of detail as an unqualified \dt command.
\dtv Returns tables and views.
\du Returns database users and whether they are superusers.
\dv

Unqualified by a pattern argument, returns all views with their schema names, owners, and comments. If qualified by a pattern argument, \dv returns all matching views and the columns in each view, with each column's data type and size.
