Question

我有一个工作的声明：

CASE [Level 1] 
WHEN '2017' THEN '' 
WHEN '2016' THEN '' 
WHEN '2015' THEN '' 
WHEN '2014' THEN '' 
ELSE [Level 1] 
END 

我试图做这样的事情，但它不工作：如何使这个

CASE WHEN [LEVEL 1] 
LIKE 'CALENDAR MONTH%' THEN 'CALENDAR MONTH' 
LIKE 'CALENDAR WEEK%' THEN 'CALENDAR WEEK' 
LIKE 'CALENDAR QUARTER%' THEN 'CALENDAR QUARTER' 
ELSE '[LEVEL 1] 
END 

建议第二个声明工作？

Answer 1

你想是这样的：

CASE WHEN [LEVEL 1] LIKE 'CALENDAR MONTH%' THEN 'CALENDAR MONTH' 
     WHEN [LEVEL 1] LIKE 'CALENDAR WEEK%' THEN 'CALENDAR WEEK' 
     WHEN [LEVEL 1] LIKE 'CALENDAR QUARTER%' THEN 'CALENDAR QUARTER' 
     ELSE [LEVEL 1] 
    END
