SHOW DATABASE

Displays configuration parameter values that are set for the database.

You can also get detailed information on configuration parameters, including their current and default values, by querying system table CONFIGURATION_PARAMETERS.

If the configuration parameter is set but requires a database restart to take effect, the value shown might differ from the active value.

Syntax

SHOW DATABASE db‑spec { parameter‑name[,…] | ALL }

Parameters

db‑spec

Specifies the current database, set to the database name or DEFAULT.
parameter‑name

Names of one or more configuration parameters to show. Non-superusers can only specify parameters whose settings are not masked by SHOW DATABASE…ALL, otherwise Vertica returns an error.

If you specify a single parameter that is not set, SHOW DATABASE returns an empty row for that parameter.

To obtain the names of database-level parameters, query system table CONFIGURATION_PARAMETERS.

ALL Shows all configuration parameters set at the database level. For non-superusers, Vertica masks settings of security parameters, which only superusers can access.

Privileges

  • Superuser: Shows all database parameter settings.
  • Non-superuser: Masks all security parameter settings, which only superusers can access. To determine which parameters require superuser privileges, query system table CONFIGURATION_PARAMETERS.

Examples

Show to a non-superuser all configuration parameters that are set on the database:

=> SHOW DATABASE DEFAULT ALL;
              name              | setting
--------------------------------+----------
 AllowNumericOverflow           | 1
 CopyFaultTolerantExpressions   | 1
 EnableSSL                      | 1
 GlobalHeirUsername             | ********
 MaxClientSessions              | 50
 NumericSumExtraPrecisionDigits | 0
(6 rows)

Show settings for two configuration parameters:

=> SHOW DATABASE DEFAULT AllowNumericOverflow, NumericSumExtraPrecisionDigits;
              name              | setting
--------------------------------+---------
 AllowNumericOverflow           | 1
 NumericSumExtraPrecisionDigits | 0
(2 rows)
