Read formula from Excel file and apply in script

sjhussain — Sat, 16 Nov 2024 03:00:55 GMT

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.

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,

PFA for ref.
