SQLSTATE[IMSSP]: The active result for the query contains no fields.

[dipens]

I have this very simple stored procedure execution on my server setup (SQL Server 2012 on a Windows Server connected to Ubuntu 16.04 running Symfony 3.3 on PHP 7.1 using these drivers ofcourse)

$connection = $em->getConnection()->getWrappedConnection();
$stmt = $connection->prepare('StoredProcedureName @a= :a, @b= :b, @c= :c');
$stmt->execute(array(
    'a'=> 'a',
    'b'=> 'b',
    'c'=> 'c',
));
$stmt->nextRowset();
$result = $stmt->fetchAll();

This works fine when there are records being returned. but sometimes depending on the parameters, the stored procedure returns no records. That's when I get this error:

SQLSTATE[IMSSP]: The active result for the query contains no fields.

I have already looked into here, here, here, and in issues here too but couldn't find a solution. I have already set SET NOCOUNT ON in the beginning of the stored procedure.

Is there anything I am missing here or is this a bug?

Hi @dipens, could you provide a complete repro script for this error, the stored procedure you are using, and parameters that trigger the error? Thanks

[dipens]

Sure @david-puglielli and I apologize for the delay in my reply. Here is the complete repro.

CREATE  PROCEDURE [dbo].StoredProcedureName @a int, @b nvarchar(50),@c nvarchar(50)
AS
SET NOCOUNT ON

DECLARE @d nvarchar(30), @f int, @e INT, @h INT
SELECT @d=d,@e=e, @f=f FROM tblA WHERE a=@a

If @d='d'
BEGIN

	DECLARE @g INT

	UPDATE tblA set 
	AStatus = 1,
	Where a = @a
		
	exec [dbo].AnotherStoredProcedure @a=@a

	exec [dbo].YetAnotherStoredProcedure @a=@a OUTPUT,@j='j'

	Update tblb set bStatus='b' where b=@b

	UpDate tblc set cStatus='c' WHERE c=@c

	exec [dbo].OneMoreStoredProcedure @g=@g,@f=@f,@e=@e,@h=@h OUTPUT,@b=@b,@c=@c,@j='j'

	SELECT @g as newPK, @h as hPK

END
ELSE
BEGIN
	UPDATE tblA set 
	AStatus = 1,
	Where a = @a
END
GO

The PHP script is the same as mentioned above.

As you can see in the stored procedure, there is an IF...ELSE condition in which the first IF returns one record at the end. This is where the method is working fine and everything is being returned as it should. However in the second part, there is nothing being returned except for the simple UPDATE statement.

Please let me know if any other information is required. Thank you for your time.

Hi @dipens, I am having trouble reproducing this issue, and I suspect it's because I'm not using the correct table design. Could you please provide the table schema for the tables referenced in the stored procedure? Thanks.

[dipens]

Hello @david-puglielli I have tried this with a very basic test table as well and the issue still exists so I doubt its the table design that's causing this.

However, I do realize now that I posted code which was relevant to PHP but not Symfony (where I am facing this). This is my Symfony version of the code: (I apologize for this)

$rsm = new ResultSetMapping();
$rsm->addScalarResult('u', 'newPK', 'newPK');
$rsm->addScalarResult('u', 'PK', 'PK');
$query = $em->createNativeQuery('StoredProcedureName @a= :a, @b= :b, @c= :c', $rsm);
$query->setParameter('a', 'a');
$query->setParameter('b', 'b');
$query->setParameter('c', 'c');
$result = $query->getArrayResult();
var_dump($result);

And nevertheless, as requested, I am also providing you table design with the very barebone Stored Procedure:

Stored Procedure:

CREATE PROCEDURE [dbo].[TestStoredProc] @a nvarchar, @b nvarchar(50),@c nvarchar(50)
AS
SET NOCOUNT ON
DECLARE @d nvarchar(30)
SELECT @d=d FROM tblA WHERE a=@a
BEGIN
	If @d='d'
	BEGIN
			SELECT 1 as newPK, 1 as PK
	END
	ELSE
	BEGIN
		UPDATE tblA set 
		AStatus = 'a'
		Where a = @a
	END
END
GO

Table Structure:

CREATE TABLE [dbo].[tblA](
	[a] [nvarchar](50) NULL,
	[d] [nvarchar](50) NULL,
	[AStatus] [nvarchar](50) NULL,
	[id] [int] IDENTITY(1,1) NOT NULL,
 CONSTRAINT [PK_tblA] PRIMARY KEY CLUSTERED 
(
	[id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO

I have tried with this barebone structure and I am able to reproduce the issue.

Please let me know if any more information is required. Thank you for your time and I apologize for the confusion above.

[david-puglielli]

Thank you @dipens, I have one more question for you. Does the issue occur without symfony? For example using the PHP snippet you provided in the first post?

Without using symfony, I am getting a different error, using the following:

$connection = new PDO( "sqlsrv:Server=$server;database=$db;" , $uid, $pwd);
$stmt = $connection->prepare('StoredProcedureName @a= :a, @b= :b, @c= :c');
$stmt->execute(array(
    'a'=> 'a',
    'b'=> 'b',
    'c'=> 'c',
));
print_r($stmt->errorInfo());
$stmt->nextRowset();
$result = $stmt->fetchAll();
print_r($result);

The output is the following:

Array
(
    [0] => 42000
    [1] => 8114
    [2] => [Microsoft][ODBC Driver 13 for SQL Server][SQL Server]Error converting data type nvarchar to int.
)
Array
(
)

The error message is from the print_r($stmt->errorInfo()); statement, and the empty array is the $result. Does this error message occur for you?

[dipens]

Hello @david-puglielli, I tried this and this is what I got:

Array
(
    [0] => 00000
    [1] => 
    [2] => 
)
Array
(
)

for both type of inputs (in the if loop I used @d='d' and @d = 'b' for the else part) which means no output was returned what so ever.

However while testing this if I removed the line $stmt->nextRowset(); it did return me the records for the if part correctly like this:

Array
(
    [0] => 00000
    [1] => 
    [2] => 
)
Array
(
    [0] => Array
        (
            [newPK] => 1
            [0] => 1
            [shipPK] => 1
            [1] => 1
        )

)

However when I tried to run the else part, it threw the same error again:

SQLSTATE[IMSSP]: The active result for the query contains no fields.

Could this line $stmt->nextRowset(); be the reason I am getting into this problem?

[david-puglielli]

Since there is only one row in the result set, calling nextRowset() is not expected to return anything, but I still cannot reproduce the error message SQLSTATE[IMSSP]: The active result for the query contains no fields. I can reproduce all your other results however.

Could you let us know what version of the PHP drivers are you using, and what version of the ODBC driver too?

[dipens]

Here is the driver information:

msodbcsql/xenial,now 13.0.1.0-1 amd64 [installed]
mssql-tools/xenial,now 14.0.1.246-1 amd64 [installed]
unixodbc-dev-utf16/xenial,now 2.3.1-2 amd64 [installed]
unixodbc-utf16/xenial,now 2.3.1-2 amd64 [installed,automatic]

[david-puglielli]

Curiously, I can get the error message when hitting the 'else' part of the procedure, but only if I do not call nextRowset.

What version of the PDO_SQLSRV driver are you using? You can find out by running php --ri pdo_sqlsrv.

[dipens]

Extension 'pdo_sqlsrv.' not present.

Not sure how that happened. All I did was follow instructions from here

However in my phpinfo() I get this version:

4.0.8.0

[david-puglielli]

I think you accidentally left the period at the end - php --ri pdo_sqlsrv

[dipens]

Sorry you are right.

This is the result

pdo_sqlsrv

pdo_sqlsrv support => enabled
ExtensionVer => 4.0.8.0

Directive => Local Value => Master Value
pdo_sqlsrv.log_severity => 0 => 0
pdo_sqlsrv.client_buffer_max_kb_size => 10240 => 10240

[david-puglielli]

Ah, I see you are using an old version. Your version does not include more recent changes to the behaviour when fetching result sets. Please download the latest preview release here or the latest production release here.
