Created Unassigned: Cannot use transactions if there are any open recordsets [22420]

luisdev — Fri, 07 Jun 2013 11:09:11 GMT

It seems that SQL Server does not allow more than one recordset to be opened at the same time. So any code doing the something like this will fail:
- open recordset
- open recordset

To solve that limitation the "Multiple Active Result Sets" mode (MARS) was created and the combination above started to work.

But the MARS mode has some limitations about what can and what cannot be done. One of these is that we cannot use transactions if there are any open recordsets. That means that any code doing the following will fail:
- open recordset
- start transaction

Is there any way to get around this?

Commented Issue: Cannot backup a database and retrieve multiple results in one statement [22419]

MaxiWheat — Tue, 11 Dec 2012 15:29:36 GMT

In our application, we need to be able to backup a database from PHP and also retrieve data from SELECTs in the same statement. Actually, we run all this code in a Stored Procedure in SQL Server 2008 but we were able to reproduce the same exact problem with a simple query. Our application is made to work in UTF-8 and display html using this encoding. What happens here is that PHP is crashing in this particular case, which is very bad. We found out that if we remove 'CharacterSet' => 'UTF-8', the issue is gone, the database gets backed up and data is returned (but I guess utf-8 strings are messed up if any) and we think it has something to do with UTF-8 encoding of error messages, as reported in a Stackoverflow question here (which I also commented) : http://stackoverflow.com/questions/9621858/sqlsrv-php-driver-and-utf-8-encoding-issue-with-error-messages

Here is the source code to reproduce the error :

<?php
sqlsrv_configure('WarningsReturnAsErrors', 0);

$result = array();

$connInfo = array(
"Database"=>"myDB",
"UID"=>"sa", // using sa to demonstrate it's not a permission issue
"PWD"=>"saPassword",
'APP' => 'MyApp',
'LoginTimeout' => 5,
'MultipleActiveResultSets' => true,
'ReturnDatesAsStrings' => true,
'CharacterSet' => 'UTF-8'
);

$conn = sqlsrv_connect('myserverhost', $connInfo);

$query = "BACKUP DATABASE [SomeDB]
TO DISK = 'C:\\Backup\\test_backup.bak'
WITH
NOFORMAT,
INIT,
NAME = 'super backup',
NOREWIND,
NOUNLOAD,
SKIP;
SELECT 1;
SELECT 2;";

$stmt = sqlsrv_prepare($conn, $query);

sqlsrv_execute( $stmt );

// Fetch first result set
while($row = sqlsrv_fetch_array( $stmt, SQLSRV_FETCH_ASSOC)) {
$result[] = $row;
}

// Fetch all next result sets
while($rs = sqlsrv_next_result($stmt)) {
$result[] = sqlsrv_fetch_array( $stmt, SQLSRV_FETCH_ASSOC);
}

sqlsrv_free_stmt($stmt);
sqlsrv_close($conn);
?>

If more details are needed I can provide them.

Hope the issue gets resolved soon
Comments: Here is what is returned by sqlsrv_client_info : Array ( [DriverDllName] => sqlncli11.dll [DriverODBCVer] => 03.80 [DriverVer] => 11.00.2100 [ExtensionVer] => 3.0.3421.0 ) And this is what comes from sqlsrv_server_info : Array ( [CurrentDatabase] => myDB [SQLServerVersion] => 10.00.5500 [SQLServerName] => myserverhost) Yes I know that messages are not retrieved by sqlsrv_fetch_array, and I'm not really interested in retrieving them, but what happens here, is that it makes PHP crash. What makes PHP actually crash is the second call to sqlsrv_next_result (in the while loop) and we don't really explain it, so we think it's a bug. We run Zend Server 5.6 (PHP 5.3.14) on Windows Server 2008 R2 Standard Edition Service Pack 1

Comments: What version of the driver are you using? I tried something similar to your code in Japanese, German, Russian and English and they all worked, with the correct encoding, and with your SELECT statements at the end. Do you know that the sqlsrv warning messages are *not* retrieved using sqlsrv_fetch_array? If you need more help, please ask a question on the forum: http://social.msdn.microsoft.com/Forums/en-US/sqldriverforphp/threads There is a post in the forum about how to do a plain backup: http://social.msdn.microsoft.com/Forums/da/sqldriverforphp/thread/e0908b2f-4afa-4626-830d-9683486186c8

Commented Issue: Problem with sqlsrv_next_result/lastinsertid after insert on table with trigger [22418]

lordlamer — Thu, 06 Dec 2012 08:45:55 GMT

Hi, i have a table with an insert trigger defined. I made an insert on this table and want to get the inserted id. So i made this: $sql = 'INSERT INTO "content" ("parent", "name", "content", "created_by", "changed_by", "create_date", "change_date") VALUES (?, ?, ?, ?, ?, ?, ?) SELECT SCOPE_IDENTITY() as Current_Identity'; $params = array(1, 'TTTTTTTTTTTTT', 'TTTTTTTTTTTTT', 0, 0, '20121128 20:01:57', '20121128 20:01:57'); $stmt = sqlsrv_query( $conn, $sql, $params); To get the Current_Identity i need to make two sqlsrv_next_result. If i delete the trigger it works with only one sqlsrv_next_result. This sounds like a bug for me. Attached is an example script. I used php 5.4 with sqlsrv 3.0.1 regards, Frank

Closed Issue: Encoding Hash Table - Zend Hash Table error [21609]

icosahedron — Tue, 30 Oct 2012 17:59:33 GMT

The following errors are occuring when at least two users tries to query a SQL Server 2005 database using sqlsrv (php_sqlsrv_52_ts_vc6.dll) with php 5.2.9 and apache 2.2 AT THE SAME TIME (same functionality). Sometimes it works, sometimes it breaks...

- An error occurred creating or accessing a Zend hash table
- Fatal: Error retrieving encoding from encoding hash table
Comments: Closing since the user found a solution. The problem was likely related to their usage of SQL Server itself.

Created Issue: PHP sqlsrv 3.0.1 Driver: sqlsrv_field_metadata returns column name as char*, so unicode column names can't be fetched correctly [22417]

WRead — Tue, 25 Sep 2012 20:17:27 GMT

Customer uses unicode column names:

CREATE TABLE Greek
(
[γεια σας κόσμο] [nvarchar](100) NOT NULL,
[привет мир] [nvarchar](100) NOT NULL,
[こんにちは世界] [nvarchar](100) NOT NULL
);

calling sqlsrv_field_metadata converts names to ANSI char strings:

Result 3 Row 2:Array
(
[0] => hello world
[?e?a sa? ??s�?] => hello world
[1] => hello world
[?????? ???] => hello world
[2] => hello world
[???????] => hello world
)

Here are some of the source code changes we would need to make to fix this:

Core_sqlsrv.h:

sqlsrv_malloc_auto_ptr<SQLCHAR> field_name;

…change to:

sqlsrv_malloc_auto_ptr<SQLWCHAR> field_name;

core_stmt.cpp:

meta_data->field_name = static_cast<SQLCHAR*>( sqlsrv_malloc( SS_MAXCOLNAMELEN + 1 ));

try {

core::SQLDescribeCol( stmt, colno + 1, meta_data->field_name.get(), SS_MAXCOLNAMELEN, &field_name_len,

…change to:

meta_data->field_name = static_cast<SQLWCHAR*>( sqlsrv_malloc( SS_MAXCOLNAMELEN + 1 ));

try {

core::SQLDescribeColW( stmt, colno + 1, meta_data->field_name.get(), SS_MAXCOLNAMELEN, &field_name_len,

stmt.cpp:

core::sqlsrv_add_assoc_string( *stmt, field_array, FieldMetaData::NAME,

reinterpret_cast<char*>( core_meta_data->field_name.get() ), 0 TSRMLS_CC );

…change to:

core::sqlsrv_add_assoc_string( *stmt, field_array, FieldMetaData::NAME,

reinterpret_cast< wchar_t*>( core_meta_data->field_name.get() ), 0 TSRMLS_CC );

Pdo_stmt.cpp:

// Set the name

column_data->name = reinterpret_cast<char*>( core_meta_data->field_name.get());

…change to:

column_data->name = reinterpret_cast< wchar_t*>( core_meta_data->field_name.get());

Commented Issue: PDOStatement execute error [22416]

jguerin — Mon, 21 May 2012 15:01:32 GMT

I am using PHP 5.4 (zend 5.6), IIS 7.5, and SQLSRV-PHP driver on my development machine. I tried inserting some data into SQL2008R2 database using the new driver but to my surprise every time i run execute(), it inserts the same record twice. Below is my code:

$pdo = new PDO("sqlsrv:server=(local);database=devDb;");
$sql = "insert into tblTest (name,ts) values(:name, :ts)";
$stmt = $pdo->prepare($sql);
$args = array(':name'=>'Some Value',':ts'=>microtime(true));
if( $stmt->execute($args) ){
.....
}

When i run and check the db, it creates 2 records with a difference in the ts field of some few micro seconds. On my production system which is running PHP5.3, that is not an issue.
Could it be a problem in the driver or PHP itself

Closed Issue: bindValue() is not accepting non-english chars [22415]

I cannot put non english chars as params in bindValue(), like à.

Please see this code: http://pastebin.com/QBahEFBG

It triggers this exception:

Database::DataTable: IMSSP - SQLSTATE[IMSSP]: An error occurred translating string for input param 1 to UCS-2: No mapping for the Unicode character exists in the target multi-byte code page.

Please note that enabling the commented-out line (setAttribute) doesn't help.
Any idea?

Excuse me, I created the file under Linux in UTF-8. Then I copied it in Windows and updated db params with notepad++, which changed the encoding.

The issue does not exist and can be closed.

Is your source file UTF-8 encoded, or have you tried something like this?:

I am using the 1.1 driver on PHP 5.3, SQL Server 2000.
Comments: ** Comment from web user: tomkraw1 **

Last year I released an application using PHP SQL driver v 2. It works on IIS 6, FCGI, PHP 5.3 and SQL 2000. Everything works well except those parametrized queries mensioned by @michalkocarek.

SQL 2000 works with this driver and PHP 5.3 if you have "Microsoft SQL Server 2005 Backward Compatibility Components" installed and SNAC.

@AshayC if you could suggest where is the probblem I will test it.
