What I'm trying to do is pull up profile info w/ the profile's comments. I get everything as expected. No error returned, array is formatted perfectly. My concern is the queries that are run. It runs one query for each ID to get its photo (the start of the query is noted in comments in the code below). I guess this is the only way to get...
I have 2 database tables: Teams and Games. For the purpose of this question, we are dealing with football (soccer) teams and games. Each Game has exactly 2 teams, generally a home team and an away team although occasionally both teams can be neutral. My question is whether I should represent this data relationship using 2 foreign keys...

Hello all, this is a simple question. There are some queries on our site that take too many seconds to complete (like 15 seconds!). For anonymous traffic they get a cached .html file, but for logged in users it's too slow. The query looks like this: SELECT node.nid, votingapi_cache_vote_percent_average.value AS votingapi_cache_vote_...
Hello, Is there any way, when using Doctrine, to create a table like another? I know in MySQL there is a function to do so: CREATE TABLE user2 LIKE user; and tables user and user2 will be identical. Can this be done in Doctrine? ...

I'm still somewhat new to Java and trying to insert data into a database. I'm getting an error when inserting a string containing 's so my end result would be to escape the apostrophe. How can I accomplish? ...
We have a pile of old databases in archives that have a column named RANGE in one of the tables. These database could have been created in MySQL 4.1 or 5.0. In MySQL 5.1+, RANGE is apparently a keyword for the query language. So now we have to change our schema for that table or we won't have any data at all. Just to be clear, its not...

Is there a way to select multiple values with prepared statements in (My-)SQL? I'm trying to select a couple of rows from a table with the IN-keyword, something like: SELECT * FROM table where id IN (1, 2, 3) The "1, 2, 3" should be passed as a parameter of the statement. Is this possible with PHP/PDO or do I have to concaterate...
I'm trying to find out if a row exists in a table. Using MySQL, is it better to do a query like this: SELECT COUNT(*) AS total FROM table1 WHERE ... and check to see if the total is non-zero or is it better to do a query like this: SELECT * FROM table1 WHERE ... LIMIT 1 and check to see if any rows were returned? In both queries, ...
Mysql's Innodb has concepts of page, extent, segment, tablespace but I don't know how they interact with each other. How are they related? What does it mean a tablespace has 16K of pages? How does this relate to the physical rows and is 'pages' something in the memory? I would assume that Oracle might have the same concept but I'm not s...

I'm currently exploring if a custom MySQL engine could fulfill my needs. I've been looking at http://forge.mysql.com/wiki/MySQL_Internals_Custom_Engine. One thing I wonder is: can I create an engine using an already existing (binary) file? If yes, I guess(?) there is no "CREATE TABLE..." so, how does MySQL know about this table? EDITED...
My delete.php is sending the selected item to the db as dead as it should, but the blog is still staying on the page that its deleted from.
