上面的脚本确实有效。我的问题是为什么第二和第三个SELECT语句需要在括号内。 ()。你在我的剧本中看到任何问题吗?
如果我在下面使用,我会收到错误:
SELECT CASE s.Country WHEN 1 THEN 'One' WHEN 2 THEN 'Two'
WHEN 3 THEN 'Three' ELSE 'Your message.' END
,SELECT CASE DoYouWishToP When 0 Then 'Yes' When 1 Then 'No' END
答案 0 :(得分:3)
他们没有。将查询写为:
SELECT (CASE s.Country
WHEN 1 THEN 'One'
WHEN 2 THEN 'Two'
WHEN 3 THEN 'Three'
ELSE 'Your message.'
END),
(CASE DoYouWishToP When 0 Then 'Yes' When 1 Then 'No' END),
(CASE Housingoptions
When 'rb0' Then 'Lease'
When 'rb1' then 'im lazy'
when 'rb2' Then 'Rental'
END)
from tblSurvey s;
