If you use a database name with the table name you get an error in the driver.  It does not matter if this name is remote, local or the current database.  I have seen this in different drivers including pdo_odbc and pdo_informix.  They all behave the same way.

Reproduce code:
        $conn = new PDO('odbc:SAMPLE', 'uname', 'pass');
        $conn->exec('CREATE TABLE test (id INT)');
        $conn->exec('INSERT INTO test(id) VALUES (1)');
        $sql  = "SELECT id FROM SAMPLE:test";
        $stmt = $conn->query($sql);
        $num  = $stmt->fetch( PDO::FETCH_BOTH );
        print "Counted $num rows after $action: $num[0].\n";

Expected result:
Counted Array rows after : 1.

Actual result:
Fatal error: Call to a member function fetch() on a non-object in ~/b.php on line 9

Wouldn't standard SQL be:

  $sql  = "SELECT id FROM SAMPLE.test";

(period rather than colon)

We thought that the issue is the delimiter that PDO is using for param passing.  For example, "SELECT * FROM dbname:table" would be parsed into "SELECT * FROM dbname".  Let me know if I am wrong in my thoughts.  

Also, Informix uses the following syntax: dbname:owner.table

Any update on the issue on why the SELECT query is being parsed incorrectly?

Informix has the ability to select data from tables that are not in the current database.  The Informix syntax for a distributed query looks like :-


or if the database is within the same Informix instance 


The problem is that ':' is used to denote a binding param in PDO . PDO will rewrite the above statment to look like :-


which is incorrect and generates a syntax error from Informix even thou the initial syntax ( SELECT * FROM DBNAME:TABNAME ) is valid.

Is any more info required ?

Maybe the query re-writing within PDO should just do param replacement after the WHERE clause . 



Currently PDO re-writes the above as
