PDO include table name prefixes in FETCH_ASSOC

Many of my MySQL tables have columns with the same name. I want to have
PDO include table names in named result sets. For example:

$sth = $dbh->prepare("SELECT * FROM table0, table1");
$result = $sth->fetchAll(PDO::FETCH_ASSOC);


I want $result to be organized like:

echo $result["table0.column0"];
echo $result["table0.column1"];
echo $result["table1.column0"];
echo $result["table1.column1"];


Or, alternatively:

echo $result["table0"]["column0"];
echo $result["table0"]["column1"];
echo $result["table1"]["column0"];
echo $result["table1"]["column1"];


Any ideas? Thanks!

The data coming from the server dictates the column names, not PDO.

If you need to identify the names, then use aliases in the SQL.

Sounds like you want to UNION two SELECTs
http://dev.mysql.com/doc/refman/5.0/en/union.html

(SELECT col1, col2, col4 FROM table1 WHERE ... ORDER BY ...)
UNION
(SELECT col1, col2, col4 FROM table2 WHERE ... ORDER BY ...)

Re: PDO include table name prefixes in FETCH_ASSOC

Thanks for the advise. I wanted a more automatic method of prefixing
column names, but I ended up just aliasing them all.

I know I could always just issue multiple SELECTs, but I wish MySQL
would support this sort of functionality natively. I'd really like to
reference my results as $result["table0"]["column0"] from a single SELECT.

Anyways, thanks all.

I use MS SQL and have used other DBs. I've never seen the table name
as part of the column name in a result set on any of them.
