Mysql - Simple select query returns duplicate values?

This is how the query looks like: (simplified)

SELECT * FROM posts WHERE user='37' ORDER BY date DESC

I currently only ave one row in that table, but still for some reason it returns two rows that are exactly the same. At first i thought i messed up with the loop, but i tried printing the returned array out with print_r() and it actually returns two rows.

I tried searching, but i didn't find any similar issues. I do however remember that a friend of mine had the same issue at school, so i'm sure we aint the only ones. I probably just didn't use the right sear开发者_StackOverflow中文版ch terms, heh.

If you have only one record (verify this), it has to be application logic that is duplicating the returned values.

Are you sure you only have one row in the table? If so, it seems like the problem must be happening outside of SQL.

What are you doing outside of this query? That seems like the likely source of the issue. You mention a loop: could you be adding the query result to your array twice? Or is the array persisting between calls without being reinitialized (in other words, the result of a previous query is remaining in the array when you don't expect it to)?

limit 1 is your friend :)

Try adding it to the end of your query.
