Topic: Using OR and AND together

[mapleleaf]

I am trying to get this to work:
SELECT * FROM articles WHERE (SELECT * FROM articles WHERE theme_id = 10 OR FIND_IN_SET(9, second_theme)) AND name = 'john' AND deleted = 'No'

My error is:
Operand should contain 1 column(s)

What is the way around this?
This query is dynamic in that multiple ANDS are sometimes added.

SELECT * FROM articles WHERE theme_id = 10 AND name = 'John' AND deleted = 'No' AND find_in_set(9, second_theme) is not null

[mapleleaf]

Getting an odd error with this.
SELECT * FROM articles WHERE FIND_IN_SET(32, second_theme) AND deleted = 'No'
//gives 16 rows

SELECT * FROM articles WHERE theme_id = 34 AND deleted = 'No'
//gives 13 rows

SELECT * FROM articles WHERE theme_id = 34 OR find_in_set(32, second_theme) AND deleted = 'No'
//gives 32 rows because 3 of the rows have 'Yes' for deleted.
SELECT * FROM articles WHERE theme_id = 34 AND find_in_set(32, second_theme) IS NOT NULL AND deleted = 'No' 
//gives 13 rows so basically excludes all the second_theme



I want to to be able to do the OR and then the AND conditions should be applied the results of the OR.

SELECT * FROM articles WHERE (theme_id = 34 OR find_in_set(32, second_theme)) AND deleted = 'No';

Is what I needed.
