Set & Let

[qlikview979]

Hi friends,

What is Set & Let  where we use Set & Let?

[sebastianlettner · Accepted solution]

Hi,

with SET you just can assign a value, with LET you can make a calculation and assign the outupt.

SET varS=1+1;     // varS = '1+1'

LET varL=1+1;     // varL = 2

Hi

SET simply assigns what is after the equal to operator whereas let evaluates what is after the equal to operator.

Example:

2*2

Using SET the result will be 2*2

Using LET the result will be 4

Thanks

SET variable name =string;

it can be only used in script

and  with Set only assign the value .

LET:

Let evaluates the expression

it can be created through script/UI.

Let variable name=Expression

It can be used in Chart calculations passing values inside the expression.
