Using CASE's is great however when there are too many conditions it can get uber complicated, this solves a very specific problem I've encountered.

Input

boolif(value: true, expected: true, output: 'It works!', fallback: '')

Variable	Type	Required	Description
value	boolean	Yes	Boolean value from the database.
expected	boolean	Yes	The expected boolean value in order to return the output.
output	varchar	Yes	Will be returned when value and expected are a match.
fallback	varchar	Optional	Will return NULL unless set to a specific fallback when value and expected do not match.

Installation

By default it will be added to the public schema.

Usage

With default fallback:

• SELECT boolif(true, true, 'It works!'); returns 'It works!'
• SELECT boolif(false, true, 'It works!'); returns NULL

With custom fallback:

• SELECT boolif(true, true, 'It works!', 'Oh yeah!'); returns 'It works!'
• SELECT boolif(false, true, 'It works!', 'Oh yeah!'); returns 'Oh yeah!'
