Uncaught PDOException when using åäö - sql-server

Question

I use to use sqlsrv_connect but changed it to PDO.
Now i got this syntax error when using åäö.
When i used sqlsrv_connect i could do this:
SELECT Order, [Benämning], [Vår ref] FROM table
and it worked.
Now i'm trying to figure out how to do it with PDO.
So i tried:
SELECT Order, [Benämning], Antal FROM table
And got this error:
Operand type clash: text is incompatible with float
And i tried:
SELECT Order, Benämning, Antal FROM table
And i got error:
Incorrect syntax near '�'.
In the connection i added utf8:
$sql = new PDO("odbc:Driver=$driver;server=$serverName,$port;Database=$database;ConnectionPooling=0", $uid, $pwd,
array(
PDO::ATTR_PERSISTENT => true,
PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8"
)
);
Now, when pasting this i can se: PDO::MYSQL_ATTR_I... I'm connecting to SQL.. not MYSQL. Can this be the problem?
If i remove the "Benämning" column and just select columns without åäö or space the select works just fine.
UPDATE
I got åäö to work with sqlsrv instead of odbc.

You simply need to use the same driver (PHP Driver for SQL Server) and the same connection options when you create the PDO instance.
<?php
...
try
$sql = new PDO("sqlsrv:Driver=$driver;server=$server,$port;Database=$database", $uid, $pwd);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
...
} catch( PDOException $e ) {
...
}
try {
$sql = "SELECT [Vår ref], ... FROM ...";
$stmt = $conn->prepare($sql);
$stmt->execute();
} catch( PDOException $e ) {
...
}
?>
Some additional notes:
You need to quote the column name ([Vår ref]) to make the string literal a valid SQL Server identifier.
Use driver specific PDO connection attributes (PDO::SQLSRV_xxx) to add driver specific features. The PDO::MYSQL_ATTR_INIT_COMMAND option is useful if you connect to MySQL instance.
