您是否可以使用星号(*)过滤SQL Server 2008下WHERE子句中的列？

Question

例如

SELECT * FROM movies WHERE director=*

Answer 1

不,您需要使用LIKE运算符和%通配符:

SELECT * FROM movies WHERE director like '%';

Answer 2

你可以使用LIKE;

SELECT * FROM movies WHERE director LIKE '%' --all
SELECT * FROM movies WHERE director LIKE 'john landis' --exact
SELECT * FROM movies WHERE director LIKE 'steve%berg' --with wildcard
