[英]How to use WHERE and LIKE clause with JOIN statement
I'm trying to perform a JOIN
on two tables, which works fine by itself. 我正在尝试在两个表上执行
JOIN
,它本身可以正常工作。 But if I then try to add a WHERE x LIKE '%abc%'
, it doesn't work. 但是,如果我随后尝试添加
WHERE x LIKE '%abc%'
,则此方法将无效。
For example: 例如:
SELECT tbd.primarytitle, trd.averagerating
FROM tbd
INNER JOIN trd
ON tbd.tconst = trd.tconst
WHERE tbd.primarytitle LIKE '%A%'
I've tried going through all kinds of joins, and I've tried parenthesizing the first part and assigning to a table, then performing the WHERE
x LIKE
on that table, and no luck. 我尝试过各种连接,尝试将第一部分括起来并分配给表,然后在该表上执行
WHERE
x LIKE
,但没有运气。
How can I achieve this? 我该如何实现? I've tried looking at 6-7 articles but none of them address both
WHERE
and LIKE
after a JOIN
. 我尝试看了6到7篇文章,但是在
JOIN
之后,它们都没有同时解决WHERE
和LIKE
的问题。
The issue is the environment being used for the SQL. 问题是用于SQL的环境。 In MS Access, you have to use
*
instead of %
for wildcards. 在MS Access中,通配符必须使用
*
代替%
。 Simply switch the two and the query will return records. 只需将两者切换即可,查询将返回记录。
