没有键连接的查询查找 table

Question

我想创建一个 table 列表来查找另一个 table。例如

Table一个

AMOUNT	DESCRIPTION
1000	i want eat
2000	i want sleep

table b(查找)

SEARCH	Activity
eat	go to eat
sleep	go to sleep

预期结果

Amount	Activity
1000	go to eat
2000	go to sleep

我试过这样的查询，但还是不行

SELECT amount, IIF(description like '%(select search from table b)%',(select activity from table b), null) as activity
FROM table a

Answer 1

这是一种方法，但正如评论所说，您必须考虑如何真正“解析”A.Description

select A.Amount,B.Activity
from 
    tableA A
    inner join tableB B on B.Search = stuff(A.Description,1,7,'') -- remove first 7 chars

Answer 2

您也可以使用常规连接

SELECT a.amount, b.activity 
FROM tableA a
JOIN lookupTable b on a.description like '%' + b.search + '%'

query lookup table without key join
