How to use a IF function containing a certain word?

[GSung]

Hi , I would like to create a new column of data (i.e. column c)  whereby if col A  does not contain the word "number", then col C = Col B*10 and if not , col C = Col B

So for example, the first row in col A contains the word number , so col C = col B(i.e. 10) ; while the second row does not contain the word "number", so Col C = col B * 10 (20* 10= 200)

Col A	Col B	Col C (would like to generate this col)
Number of XX	10	10
Amount of YY	20	200

Hello GSung,

You can create such a column C in a Prepare recipe, by adding a Formula step.

In your case, the formula would be:

---

if(contains(toLowercase(A), "number"), B, B*10)

---

I used toLowercase to ensure that the if is case insensitive, i.e. for instance Number and number within the A column would yield the same result for C.

You can learn more about the Formula language in the documentation: https://doc.dataiku.com/dss/latest/formula/index.html

Hope this helps 😊

Thanks Agathe

and how can I expand the formula if I want the condition to contain multiple words --> either contain the word "number" or "a." ?

You might want to use an or operator here (refer to the Formula documentation: https://doc.dataiku.com/dss/latest/formula/index.html#boolean-functions).

This would be something like the following:

---

if(contains(toLowercase(A), "number") || contains(toLowercase(A), "a."), B, B*10)

---
