DAX SWITCH Function
Clean, readable conditional branching without nested IF hell.
Syntax Definition:
SWITCH( Expression, Value1, Result1, [Value2, Result2, ...], [Else] )
Overview
SWITCH evaluates an expression against a series of values and returns the corresponding result. The SWITCH(TRUE(), ...) pattern enables powerful multi-condition branching.
Architectural Deep Dive
Instead of writing 10 nested IF statements, developers use SWITCH(TRUE(), ...) to write readable case-when logic for binning customers, evaluating scorecards, and conditional KPI color indicators.
Canonical Pattern Example:
Customer Performance Tier =
SWITCH(
TRUE(),
[Total Revenue] > 10000, "Platinum",
[Total Revenue] > 5000, "Gold",
"Silver"
)Common Anti-Patterns & Mistakes to Avoid
- •Ordering conditions incorrectly: in SWITCH(TRUE(), ...), DAX evaluates top-to-bottom and stops at the first TRUE condition.
- •Returning inconsistent data types in different branch results.
