Edit report at https://bugs.php.net/bug.php?id=72503&edit=1 ID: 72503 Updated by: ab@php.net Reported by: jgeert1 at its dot jnj dot com Summary: [ODBC Cursor Library] Result set was not generated by a SELECT statement, SQL s Status: Not a bug Type: Bug Package: ODBC related Operating System: Windows Server 2008 R2 PHP Version: 5.6.23 Block user comment: N Private report: N New Comment: Typo - "if the row set size > 1". Thanks. Previous Comments: ------------------------------------------------------------------------ [2016-07-06 09:55:09] ab@php.net 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. ------------------------------------------------------------------------ [2016-07-04 13:47:46] jgeert1 at its dot jnj dot com 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. ------------------------------------------------------------------------ [2016-07-01 11:22:28] ab@php.net Please provide the full reproduce way with table creaton, data, and all the necessary things.

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 .... ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=72503&edit=1
