Description:
------------
odbc_fetch_array() reports error: SQL error: [Microsoft][SQL Server Native Client 11.0]Invalid Descriptor Index, SQL state S1002 in SQLGetData in ...

It is related to Bug #73725, that has been partially solved, but it remains by this circumstances:

This error occurs on reading result with two conditions at the same time.
First condition:
- SQL syntax contains more than one command (select or execute)
OR
- SQL command contains anything extra, f.e. "set nocount on execute ..."
OR
- SQL command contains any comment, f.e. "/* any comment */ select ..."
OR
- SQL command calls a procedure that returns more than one result

Second condition:
- one of sql results contains column type text or not empty varchar(max)


If one condition is not true, then it works OK.
There are differences between drivers "SQL Server" and "SQL Server Native Client". One doesn't like text type if it is not the last column, another driver doesn't like not empty varchar(max).
My example contains both features, so it gives an error regardless used driver.


Test script:
---------------
<?php
	header("Content-Type: text/html; charset=utf-8");
	$con=odbc_connect("Local64bit","any_user","his_pwd");
	$res1=odbc_do($con,"create procedure #p as
		select convert(text,'text 1') converted_to_text, 1 i, convert(varchar(max),'text 1') converted_to_varchar_max
		select convert(text,'text 2') converted_to_text, 1 i, convert(varchar(max),'text 2') converted_to_varchar_max
	  ");
	$res2=odbc_do($con,"execute #p");
	while($r=odbc_fetch_array($res2))
		print_r($r);
?>


Expected result:
----------------
Array
(
    [converted_to_text] => text 1
    [i] => 1
    [converted_to_varchar_max] => text 1
)


Actual result:
--------------
