Select using case shows all results - sql

Question

Two fields in the table articles:
title and body
Two records:
meow bark | 1234 5678 and bird snake | 8596 2952
Where meow bark is under title and 1234 5678 is under body, etc...
SQL Query:
SELECT *,
CASE WHEN title = 'meow' then 1 else 0 end + CASE WHEN title = 'bark' then 1 else 0 end AS matches
FROM articles
ORDER BY matches DESC
Returns both rows. Please help me understand what's wrong with my syntax. I am expecting it to return only rows where the title matches what is in the query. Unless I do not understand how CASE works, if title in the above example matches meow or bark, it should display - else, do not display.
The goal is to return results based on most matches. Take at fiddle look here: http://sqlfiddle.com/#!3/13b33/10
I modified it slightly, didn't think enough to break it though.

Answer 1

Unsure what you want to achieve ...what would you like to be returned
This might be a bit closer to what you want
SELECT *,
matches = CASE WHEN title LIKE '%meow5' THEN 1 ELSE 0 END + CASE WHEN title LIKE '%bark5' THEN 1 ELSE 0 END
FROM articles
ORDER BY matches desc
EDIT after OP has been updated
Try using the WHERE clause if you only want some of the records to be returned:
SELECT *
FROM articles
WHERE title LIKE '%meow%'
OR
title LIKE '%bark%'
ORDER BY matches desc

Try this fiddle
In case Fiddle goes out of date here is the script:
CREATE TABLE YourTable (FieldToSearch varchar(max));
INSERT INTO YourTable
VALUES
('If there were a dog'),
('If there was a dog'),
('If that dog died!'),
('I''d be happy with cat');
SELECT x.*
FROM (
SELECT FieldToSearch,
CASE WHEN ' ' + FieldToSearch + ' ' like '% if %' then 1 else 0 end
+ CASE WHEN ' ' + FieldToSearch + ' ' like '% there %' then 1 else 0 end
+ CASE WHEN ' ' + FieldToSearch + ' ' like '% was %' then 1 else 0 end
+ CASE WHEN ' ' + FieldToSearch + ' ' like '% a %' then 1 else 0 end
+ CASE WHEN ' ' + FieldToSearch + ' ' like '% dog %' then 1 else 0 end AS matches
FROM YourTable
)x
WHERE x.matches >0
ORDER BY x.matches DESC;

Answer 2

You need to put that in a WHERE clause rather than the SELECT clause if you want to exclude rows.
Also, the comparisons you are using are for equivalence. This will not "match" if the column contains your search value, as you seem to think, but only if the column has exactly the same text and nothing else (with some small allowances for collation).

Answer 3

you dont have where clause mentioned in the query, it will fetch all the records unless you filter them using where condition
