This SQL query is incomplete as it does not specify the table from which to select data. The `FROM` clause is missing, which is required to indicate the table or tables from which to retrieve data.
Additionally, the `CASE` statement in this query seems to be incomplete as well. It only specifies the conditions for the `WHEN` clauses but does not provide a value to return when those conditions are met.
Please provide more information about the database schema and tables involved in this query so that I can assist you better.
