Notes

Note: Note to Windows Users

Due to a limitation in the underlying API used by PHP (MS DBLib C API), the length of VARCHAR fields is limited to 255. If you need to store more data, use a TEXT field instead.

there are same problem with VARBINARY, if you are forced to use existing database with such fields you can do it like this:

SELECT CAST(master.dbo.fn_varbintohexstr(VARBINARYFIELD) AS TEXT) FROM table;

You can also work around this limitation with the following:

   -- for example, with MyVarCharField VARCHAR(1000)
   SELECT CAST(MyVarCharField AS TEXT) FROM MyTable
