If statement in a variable of type LET

hariprasadqv — Thu, 28 May 2015 05:01:29 GMT

Hi All,

LOAD * INLINE [

F1, F2, F3

A, 23, 18

B, 24, 12

C, 25, 34

];

lET VT1=SUM(F2);

lET vT2=SUM(F3);

Let vt= if([F1]="A",VT1,vT2);

What is the wrong with the if statement;

for the first part consider the script below. The if statement cant work as a variable can only store one value at a time.

Data:
LOAD * INLINE [
    F1, F2, F3
    A, 23, 18
    B, 24, 12
    C, 25, 34
];


sumtab:
LOAD
sum(F2) as F2sum,
sum(F3) as F3sum
Resident Data;

LET VT1 = Peek('F2sum');
LET VT2 = Peek('F3sum');

Field names are cannot use directly in the variables either it could use Peek or FieldValue

I hope your intention is different. Let me know whether below script helps you

LOAD * INLINE [

F1, F2, F3

A, 23, 18

B, 24, 12

C, 25, 34

];

T1:

Load F1, If(F1='A', Sum(F2), Sum(F3)) AS VT

Resident T

Group By F1;

Hi Daniel,

I want to pick only one value. And I have to display it in a Text Object.

please find attached a revised version

Data:
LOAD * INLINE [
    F1, F2, F3
    A, 23, 18
    B, 24, 12
    C, 25, 34
];


sumtab:
LOAD
sum(F2) as F2sum,
sum(F3) as F3sum
Resident Data;

LET VT1 = Peek('F2sum');
LET VT2 = Peek('F3sum');

Result:
LOAD
sum(if([F1]='A', $(VT1),$(VT2))) as Result
Resident Data;

LET vt = Peek('Result');

You don't need variables in script. Try this expr in Text box

=If(Max(Aggr(Max(If(F1='A',1,0)),F1)) = 1,Sum(F2),Sum(F3))
