Question

An example for data in my table

post_id|post_title|post_status

1       i         1

2       love      0

3       sof       0

i’ve problem with (OR)

i am trying this condition

WHERE post_status = '1' AND post_id = '1' OR post_title = 'i';
//it should return with i
// but it returned with love,sof

The problem is caused because of (OR) at the end in the condition

it has been disabled the earlier part of the condition

So, How i can use OR properly?

i want search in posts by both columns, post_id and post_title

NOTE:

i can’t move post_status='1' to the end of the condition for some reason, it should be in begain

Answer 1

You just need to group logically with (), otherwise, the OR condition, whenever true, will supercede the required condition post_status = 1 regardless of whether it is matched.

WHERE post_status = '1' AND (post_id = '1' OR post_title = 'i');

You should always be thinking about logical groups and precedence when constructing multipart WHERE clauses, but especially when making use of the logical OR, as it can quickly derail the rest of your clause.
