Logic

if

if(condition,yesValue,noValue)

Controls conditional branching.

For example if(1=2,'a','b') will get b

multi_if

multi_if(condition1, then1, condition2, then2.. ,else) An easier way to write if/self or case/when.

sleep

sleep(seconds)

Not necessary as a logic function, but it is a function that can be used to pause the execution for a specified number of seconds.

For example select sleep(2) will pause the execution for 2 seconds.
