Variables ?

[#1]

Hi All,

I know variables are created by using SET & LET..

How the Variables are created in that , & what are the differnet ways of creation,

how we can use in Set Analysis, how we can use in charts for various conditions...

how they are used in Date functions..? based on various dates ?

Can any one explain me with Some more examples & documents only Variables Part..

Hi

Variables play a vital role everywhere.

Let me give some examples like it is used in set date format(SET DateFormat='M/D/YYYY'), set qvd path etc.

It can also be used in dashboard to store some value in it on some action and as soon it's value gets set we can display objects conditionally depending on it's value and can cause trigger on it's value to perform other action.

Like-(if(vAllProduct='Yes',1,0)), so my chart will display only when I click  on All Product button which sets its value in Actions Tab.

Similarly, I use it in conditions in colors(if(vPremium='No',RGb(255,255,255),RGB(216,228,188)))

And variables can be created in dashboard too, in variable overview in settings.

For more uses, you will have to understand concepts like sets analysis, scripting, conditions because they use it, there is no separate topic on variables.

I hope it will help.
