SET/SHOW

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

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
