Overview

The SET statement lets you set specific options while the SHOW statement helps you see the current values in Oxla.

Syntax

The syntax for these functions is as follows:
  • SET
  • SHOW
SET <option> TO <value>;
For options that accept boolean values, <value> can be either ON or OFF, which correspond to TRUE or FALSE respectively
The available options that can be set and shown are:
  • extra_float_digits: by default, Oxla displays a limited number of digits, but you can set how many extra digits are displayed after the decimal point in floating-point numbers by using this option
  • application_name: sets a custom name for the application
  • timezone: determines the time zone used for date and time functions
  • client_min_messages: sets the message levels sent to the client (valid values are DEBUG5, DEBUG4, DEBUG3, DEBUG2, DEBUG1, LOG, NOTICE, WARNING and ERROR)
  • search_path: defines namespaces at which Oxla looks for tables
  • enable_fast_math: enables mathematical optimizations that trade precision for speed by utilizing faster, less accurate mathematical functions

Examples

SET Statement

  • Extra_float_digits
  • Client_min_messages
  • Enable_fast_math
To change the number of displayed digits for floating-point values, use the SET statement in a following way:
SET extra_float_digits TO 2;
SHOW extra_float_digits;
 extra_float_digits 
--------------------
 2

SHOW Statement

  • Timezone
  • Search_path
  • Enable_fast_math
To display the current timezone setting, use the following query:
SHOW timezone;
 timezone 
----------
 Etc/UTC
