How can I set right expression?

Thu, 20 Apr 2017 21:50:58 GMT

Hi guys,

Tell me please, How can I set expression with an exeption parameter?

For example: I have 3000 location, but 1700 is active and I need them.

Attribute: is location doesn't active "Pairing precession = -1"

This expression doesn't work:

( {<[Pairing precession]=[Pairing precession]-{'-1'}>} [Location])

Many thanks,

Yuriy

Pretty close. Something like this:

Count( {<[Pairing precession]= - {-1}>} [Location])

You need some sort of an Aggregation function (Count, Only, or anything else) in order to host your Set Analysis expression.

Not clear what you are trying to do. Can you elaborate and give us more info for below?

Attribute: is location doesn't active "Pairing precession = -1"

This expression doesn't work:

( {<[Pairing precession]=[Pairing precession]-{'-1'}>} [Location])

are you doing a set analysis with Pairing precession as -1.

May be you want to try like

= Sum( {< [Pairing precession] -= {'-1'} >} [Location])

Yes, of course. For example, I have:

ID location Pairing Precession

1	8:00:00
2	14:00:00
3	13:00:00
4	11:00:00
5	12:00:00
6	-1
7	11:00:00
8	11:00:00
9	11:00:00
10	-1
11	11:00:00
12	-1
13	11:00:00
14	-1

I want to see:

1	8:00:00
2	14:00:00
3	13:00:00
4	11:00:00
5	12:00:00
7	11:00:00
8	11:00:00
9	11:00:00
11	11:00:00
13	11:00:00

How can I do it? help me, please.

Many thanks,

Yuriy

if you have only one value for one ID then

Only({<Pairing Precession = Pairing Precession - {-1}>} Pairing Precession)

if your not successful then do this,

in your load script

Load

ID location ,

Pairing Precession,

if(Pairing Precession = -1, 0,1) as Flag;

use this in set analysis

Only({<Flag-={0}>} Pairing Precession)

You want this in the script or in the Front end?

Try like in your Straight table Dimension

= If([Pairing Precession] <> -1, [ID Location])

= Aggr(Only({< [Pairing Precession] = {'<>1'}>}), [ID Location])

Then supress Null Values.

Expr:

= [Pairing Precession]

You can use simple any one of below

Only({<[Pairing Precession] -= {'-1'}>} [Pairing Precession])

Only({<[Pairing Precession] = E({<[Pairing Precession] = {'-1'}>}[Pairing Precession])>} [Pairing Precession])
