SQL 2005可以在case语句中使用关键字

我需要一个允许部分匹配的case语句.我得到一个语法错误,但是我想知道是否有可能类似的事情.如果没有,我的第二个解决方案是重写为光标…
例：

SELECT CASE ColumnName
           WHEN 'value1' THEN 'answer1'
           WHEN 'value2' THEN 'answer2'
           WHEN LIKE '%TEST%' THEN 'answer3'
       END AS Answer
FROM TableName

解决方法

SELECT CASE 
           WHEN ColumnName = 'value1' THEN 'answer1'
           WHEN ColumnName = 'value2' THEN 'answer2'
           WHEN ColumnName LIKE '%TEST%' THEN 'answer3'
       END AS Answer
FROM TableName

你可以运行的例子

SELECT name,CASE 
           WHEN Name = 'sysobjects' THEN 'answer1'
           WHEN Name = 'syscols' THEN 'answer2'
           WHEN Name LIKE '%p%' THEN 'answer3'
           ELSE 'unknown'
       END AS Answer
FROM sysobjects
