Read formula from Excel file and apply in script

[sjhussain]

I have an excel sheet in which i have defined formulas for each of the CODE as follows:

CODE, THRESHOLD

AJS,AGE>15

AJSS, AGE<3

AGE is a column name in the same table

How can i use the THRESHOLD as a formula and then use it to define a dimension.  Something as below

if (applymap('MAP_THRESHOLD',CODE,null()),1,0) 

The applymap will return the formula and then i can apply it in the if condition.  Is there a way to use it?

Check this,

I am not still clear, what your'e trying to achieve.

MAP_THRESHOLD:
Mapping LOAD * INLINE [
    THRESHOLD, CODE
    AGE>15, AJS
    AGE<3, AJSS
];

Age:
Load *,
If (Len(applymap('MAP_THRESHOLD',Age_Bucket))>=1,1,0) as Dimension,
applymap('MAP_THRESHOLD',Age_Bucket,'#NA') as CODE;
LOAD *,
If(Age>15,'AGE>15',
IF( Age<3, 'AGE<3')) as Age_Bucket
INLINE [
    Age
    1
    2
    66
    16
    7
];

hirishv7,

Thanks for the response.

Actually what I want is to have an kind of formula as a text in the field (AGE was just an example)

CODE, FORMULA

AJS, SALES>100

AJSS, SALES <50

I want to read the formula and then apply it as a condition.  The applymap will give me the formula but how can i apply the formula as a condition.

applymap('MAP_THRESHOLD',CODE,null()) will give me the FORMULA

if(applymap('MAP_THRESHOLD',CODE,nul()),1,0) should give me the following

if(SALES>100,1,0)

but the challenge it is that it is returning text and i cannot use SALES>100 as formula.

Hope this clears.

Thanks.

Check this, using evaluate function.

Spoiler

Map:
Mapping LOAD * INLINE [
CODE, FORMULA
AJS, SALES>100
AJSS, SALES<50
];


SET vEval = Evaluate($1&$2);

Data:
LOAD *,
If($(vEval(SALES,Evaluator)),1,0) AS Validate;
LOAD *,
Mid(ApplyMap('Map',CODE),6) as Evaluator
INLINE [
CODE,SALES
AJS, 55
AJA, 89
AJS, 110
AJSS, 40
AJSS, 90
];

HTH,
