PHP, ODBC, and nvarchar
I stumbled upon an odd error using PHP's ODBC functions to query a SQL Server 2005 database. I was doing a basic SELECT statement to get the description of something when I encountered the following error:
Warning: odbc_exec() [function.odbc-exec]: SQL error: [unixODBC][FreeTDS][SQL Server]Unicode data in a Unicode-only collation or ntext data cannot be sent to clients using DB-Library (such as ISQL) or ODBC version 3.7 or earlier., SQL state in SQLExecDirect in /home/web/file.php on line 4
It turns out that the PHP ODBC functions have a hard time pulling "nvarchar" data. Here's the ugly solution to getting nvarchar data:
SELECT CAST(CAST([DetailedDescription] AS VARCHAR(8000)) AS TEXT) AS ad FROM mytable WHERE active = 1
Not pretty but making it function is what counts.

THANKS!!!
muchas gracias.. ahora puedo seguir trabajando tranquilo.. justamante estaba teniendo problemas con un campo nvarchar.
Casting to varchar limits you to 8000 characters in a field.
I found just casting to text works better, like so:
print("SELECT CAST([column_name] AS TEXT) AS column_0 FROM table_name");Thanks , nice solve problem from sql server
Cast did the job ….
Nice post !!!
not work!

Thank you very very much!
And here is how to write value:

$value = 'ŽČŘĚÝÁÖ'; $value = iconv('UTF-8', 'UTF-16LE', $value); //convert into native encoding $value = bin2hex($value); //convert into hexadecimal $query = 'INSERT INTO some_table (some_nvarchar_field) VALUES(CONVERT(nvarchar(MAX), 0x'.$value.'))';thanks a lot. i was not shure what was the problem. In the sql management studio the data looks fine and in php is not. my first impresion was user rights for the data .. but after 1 hour of hair pulling :) i wandered if culd be the odbc … and like this i found your post
thanks again
