​

Overview

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

​

Syntax

SET Syntax

SET <option> TO <value>;

SHOW <option>;

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 extra_float_digits.

• 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.
