CASE Complex statement in DAX

[Anonymous]

Hello! 🙂 

I am trying to "translate" a complex case statement in DAX. I have tried 'Switch function' and it's OK:

New field = SWITCH (

        TRUE (),

table1[Category] = "hair-color", "LUXE",

table1[Category] = "hair-care", "LUXE",

table1[Category] = "hair-style", "LUXE",

...etc

"Other"

)

What's the problem? When within the case statement I have more options for the same string:

CASE
WHEN REGEXP_MATCH(Field 1, ".*Hair-Color.*|.*Hair-Care.*|.*Hair-Style.*") THEN "Hair"
WHEN REGEXP_MATCH(Field 1, ".*Skin-Sun.*|.*Skin-Face.*|.*Skin-Body.*") THEN "Skin"

... etc

ELSE "Other"

END

How can I translate every of these options: ".*Skin-Sun.*|.*Skin-Face.*|.*Skin-Body.*"|...etc" within my Switch function in DAX?

Thanks so much in advance! 🙂

Hi @Anonymous ,

This might work?

_newField =
SWITCH(
  TRUE(),
  CONTAINSSTRING(table1[Category], "Hair"), "Hair",
  CONTAINSSTRING(table1[Category], "Skin"), "Skin",
  ...
)

@Anonymous , You can try like

New field = SWITCH (
TRUE (),
table1[Category] in ("hair-color","hair-care","hair-style"), "LUXE",
"Other"
)

But if need to search then you need use search, check

Hi Amit, 

It is throwing an error of Operator or expressions '()' is not suported in this context. 

Below ways can however work:

NEW_FIELD = SWITCH (
TRUE (),
CONTAINSSTRING(Table1[Category],"hair-color"), "LUXE",
CONTAINSSTRING(Table1[Category],"hair-care"),"LUXE",
CONTAINSSTRING(Table1[Category],"hair-style"), "LUXE"
)

and 

NEW_FIELD = SWITCH (
TRUE (),
CONTAINSSTRING(Table1[Category],"hair-color")||CONTAINSSTRING(Table1[Category],"hair-care")||
CONTAINSSTRING(Table1[Category],"hair-style"), "LUXE"
)

But I would want to see , if we can give multiple values in "IN" Statement so to avoid giving column name, using CONTAINSSTRING function again and again , like it works in Tableau by using "|" symbol and dont need to give column name repeatedly WHEN REGEXP_MATCH(Field 1, "*.Hair-Color.*|*.Hair-Care.*|.*Hair-Style.*") THEN "Hair"

Hi @Anonymous ,

You can use Amit's answer, but you need to use curly braces (not standard paretheses) around the 'IN' list, as it is a list. Amit's calculation updated would look like this:

New field =
SWITCH (
  TRUE (),
  table1[Category] IN {"hair-color", "hair-care", "hair-style"}, "LUXE",
  table1[Category] IN {"Skin-Sun", "Skin-Face", "Skin-Body"}, "SKIN",
  "Other"
)

I already suggested the CONTAINSSTRING option but Amit's method, correctly implemented, is far more performant I believe.
