Re: [PHP-DB] mssql - unable to read large text fields From: Andrew Hill (ahill <email protected>)

Your ODBC driver is treating nvarchar like varchar, which allows overloading
to 255+ characters, but only returns 255 if the driver is strict.

Either change/upgrade your ODBC driver, or use a TEXT datatype.

Best regards,
