Sorry, but your problem does not imply a bug in PHP itself. For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system
is not the
appropriate forum for asking support questions. Due to the volume
of reports we can not explain in detail here why your report is not
a bug. The support channels will be able to provide an explanation
for you.
Thank you for your interest in PHP.
Thanks for the additional info. In this case, it is an inappropriate configuration. Forward-only
cursors shouldn't be used, if the rowset size >= 1. It is documented here https://msdn.microsoft.com/en-us/library/ms715441(v=vs.85).aspx
Thanks.

Meanwhile after doing some additional testing, I noticed that I only have this error when a table
has columns defined as "ntext" or "varchar(max)" or "nvarchar(max)"
fields. If I remove these columns from my sql statement, the query runs fine again.
When I create a dummy table like this:
CREATE TABLE [dbo].[jg_test](
[id] [int] IDENTITY(1,1) NOT NULL,
[test1] [int] NULL,
[test2] [varchar](50) NULL,
[test3] [varchar](max) NULL,
[test4] [nvarchar](max) NULL,
[test5] [int] NULL
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
just add some dummy data to it (in my case the varchar fields only contain "test").
use this code to access it:
$user = "username";
$pwd = "password";
$dsn = "Driver={SQL Server Native Client
11.0};Server=myserver;Database=mydb;MARS_Connection=Yes;";
ini_set ('odbc.default_cursortype',SQL_CURSOR_FORWARD_ONLY);
$dbhandle = odbc_connect($dsn,$user,$pwd,SQL_CUR_USE_DRIVER);
$result = odbc_exec($dbhandle, "select * from dbo.jg_test");
while( $row = odbc_fetch_array($result)) {
var_dump($row);
}
odbc_free_result($dbhandle);
odbc_close($dbhandle);
This will result in the error message:
Warning: odbc_fetch_array(): SQL error: [Microsoft][SQL Server Native Client 11.0]Invalid Descriptor
Index, SQL state S1002 in SQLGetData
I know it's a different error message then the one posted before, but I'm sure that these
are related to each other.

Description:
------------
I'm currently running PHP 5.5.12 and use the odbc functions to retrieving data from MS SQL
Server databases. I've a query which runs fine (produces the expected result)when using this
PHP version.
However I would like to upgrade PHP from 5.5.12 to 5.6.23. Installation went smoothly and all
existing code seems to run fine on it except one db query, which now produces the error "[ODBC
Cursor Library] Result set was not generated by a SELECT statement, SQL state SL004 in SQLGetData
...".
I've no idea what's causing it. It runs fine when using the old version of PHP, but with
the latest one, it always fails. I also tried PHP 7.0.8, but it also produces the same error.
Test script:
---------------
$odbcmgt_dsn = "Driver={SQL Server};Server=MYSERVER;Database=MYDATABASE;";
$dbhandle = odbc_connect($odbcmgt_dsn,$odbcmgt_user,$odbcmgt_pwd,SQL_CUR_USE_ODBC);
$result = odbc_exec($dbhandle, $sql);
while( $row = odbc_fetch_array($result)) {
// data procession code
}
odbc_free_result($result);
odbc_close($dbhandle);
Expected result:
----------------
+/- 6000 rows of data
Actual result:
--------------
Error message: Warning: odbc_fetch_array(): SQL error: [Microsoft][ODBC Cursor Library] Result set
was not generated by a SELECT statement, SQL state SL004 in SQLGetData in ....
