Known Causes

3 known causes
⚠️
Missing ELSE Clause
The `CASE` statement in your SQL query lacks an `ELSE` clause, which is essential for handling situations where none of the defined `WHEN` conditions are met.
⚠️
Incomplete WHEN Conditions
The `WHEN` conditions within the `CASE` statement do not cover all possible values or states of the expression being evaluated, leaving some logical paths unaddressed.
⚠️
Unexpected Data Values
The data being processed by the query contains values that were not anticipated or explicitly handled by any of the `WHEN` clauses in the `CASE` statement.
