Description:
------------
I used ODBC Unified using a MyODBC driver version 3.51.11 and connected to a table with a varchar and a TEXT  column. Then I created a query like this:

$sql="SELECT Title FROM tbllibrarymaterials"

.. the odbc_exec function does good. It provides a non-false result. but if I have to get the rows by using odbc_fetch_row,  this function returns false and I could not get a record.

But...

If I defined another column along with the query:

$sql="SELECT Title, Call_Number FROM tbllibrarymaterials"

...I get the expected results.

[PHP.INI]
odbc.longreadlen=65535 
odbc.binmode=1

I set this because it may be the problem with long columns. But this settings did not change anything.

Reproduce code:
---------------
To reproduce the bug, you must create a table called "tbllibmaterials" (or any name) in MySQL with a varchar(50) for the Call_Number and TEXT column for the Title, and use odbc_fetch_row running the query:

$sql="SELECT Title FROM tbllibrarymaterials"

Expected result:
----------------
No records can be retrieved.

Actual result:
--------------
No records can be retrieved.
