一列为LIKE，另一列为IN

Question

I want to write a query where I have two columns to compare my data from but need a LIKE on one column. Something like this:

SELECT `name` , `country` 
FROM details
WHERE (`email`, `phone`)
IN (
("abc@abc.com",'%123'), ("def@def.com",'%456'), ("ghi@ghi.com",'%789') )

Please guide me on how I would write this query. Thanks!

Answer 1

You would simplify the where clause to:

WHERE phone LIKE '%302024' AND
      email in ('abc@abc.com', 'def@def.com', 'ghi@ghi.com')

EDIT:

For your revised question, you can use a series of AND and OR :

WHERE (phone like '%123' and email = 'abc@abc.com) OR
      . . .

If the list is long, you might want to put the values into a table and use a join or exists clause.

Answer 2

an IN statment as col IN ('Foo', 'Foo%') is equivalent to (col = 'FOO' OR col = 'Foo%') as you can see, that would not take into account the wildcard as in the LIKE clause, to achieve your requirements, you will need to divide your where clause as the following:

SELECT name, country 
  FROM details
 WHERE (phone LIKE '%123' OR phone LIKE '%456' OR phone LIKE '%789')
   AND email IN ('abc@abc.com', 'def@def.com', 'ghi@ghi.com')

Answer 3

Since one email can have multiple phone numbers but one search, you will need (or probably already have) a table with emails. In that you will need to add the search string and then do a locate instead of a like.

create table emaildetails (email char(20), phonesearch char(15))

insert into emaildetails values ("abc@abc.com", "302024")
insert into emaildetails values ("def@def.com", "024")
insert into emaildetails values ("ghi@ghi.com", "15")

select d.*,ed.* from details d, emaildetails ed
where d.email in ('abc@abc.com', 'ghi@ghi.com')
and d.email = ed.email
and locate(ed.phonesearch, d.phone)>1
