使用TSQL和PHP从存储过程返回值

Question

Is it possible to get data returned from a Stored procedure in PHP using SQLSRV connecting to a windows server DB. At the moment, the code I have commits the query succesfully but doesn't return anything. The loop where the rows output does not run even once (ie the object is empty)

Here's the PHP

/* Set up and execute the first query. */
$sql1 = "
USE CRDCMS2PublicDevelopment
EXEC SearchForXML6b 
@SessionID = 973543,
@LineID = 892245,
@SortOrder = 'YearPublished DESC, SortTitle ASC',
@PageNumber = 1,
@RecordsPerPage = 20
";
$params1 = array( $orderId, $qty, $productId );
$stmt1 = sqlsrv_query( $conn, $sql1/*, $params1*/ );

/* Display the value of the output parameters. */   
while ( $obj = sqlsrv_fetch_object( $stmt1 ) ) {       
    //SET PARAMETERS - SET TERMS    
    echo 'loop';  
    echo $obj->listingXML;
}

/* If both queries were successful, commit the transaction. */
/* Otherwise, rollback the transaction. */
if( $stmt1 ) {
     sqlsrv_commit( $conn );
     echo "Transaction committed.<br />";
} else {
     sqlsrv_rollback( $conn );
     echo "Transaction rolled back.<br />";
}

Here's the Stored procedure

USE [ my db name ]
GO
/****** Object:  StoredProcedure [dbo].[ SPROC name ]    Script Date: 12/08/2013 14:45:37 ******/
SET ANSI_NULLS ON

        SET @PageNumber = 1

        SET @RecordsPerPage = 20

    DECLARE @sql nvarchar(max)
    set @sql = '

        DECLARE @startRow int
        DECLARE @endRow int
        SET @startRow = '+STR(((@PageNumber-1) * @RecordsPerPage)) + '

        DECLARE @total int

        DECLARE @t TABLE (RowNumber int IDENTITY, AccessionNumber bigint not null, SortTitle nvarchar(450), YearPublished int, DatabaseID int, RecordTypeID int, Selected int NULL, Source nvarchar(450))'



        SET @sql = @sql + '
  DECLARE @hits varchar(max)

  SELECT @hits = Hits from UserHitTemp where LineID = ' + LTRIM(RTRIM(STR(@lineID))) + '  

        insert into @t ( AccessionNumber, SortTitle , YearPublished , DatabaseID , RecordTypeID , Source)
            SELECT C.AccessionNumber, SortTitle, YearPublished, DatabaseID, RecordTypeID, ISNULL((select top 1 FieldText from SearchField where AccessionNumber = C.accessionNumber and SearchTag = ''SO''),'''') as Source 
            FROM dbo.SplitAccessionList(@hits) H
            JOIN CRDDocument C on C.AccessionNumber = H.AccessionNumber ORDER BY ' + @SortOrder



    SET @sql = @sql + '
        set @total = @@ROWCOUNT

        DECLARE @xml XML
        SET @xml = (
        SELECT TOP 1 @total as "@RecordCount",
            0 as "@SelectedCount",
            '+LTRIM(RTRIM(STR(@SessionID)))+' as "@SearchSessionID",
            '+LTRIM(RTRIM(STR(@PageNumber)))+' as "@PageNumber",
            '+LTRIM(RTRIM(STR(@RecordsPerPage)))+' as "@RecordsPerPage",
            '+LTRIM(RTRIM(STR(@LineID)))+' as "@LineID",
            ''advanced)'' as "@SearchType",

            (   SELECT dbo.GetRecordForListingXML(AccessionNumber, RowNumber,ISNULL(Selected,0)) 
                FROM @t T
                WHERE T.RowNumber > @startRow and T.RowNumber < @endRow

                FOR XML PATH(''''), ELEMENTS, TYPE
            )
            FOR XML PATH(''listing''), ELEMENTS
        )

        SELECT @XML as listingXML'

    -- ----------------------------------------------------------------------------------------------
    -- Run the SQL to extract the results as XML
    -- ----------------------------------------------------------------------------------------------

    PRINT @sql

    EXEC sp_executesql @sql

END

Please note: if i copy and paste the exact sql used in the php ($sql1) it returns one row correctly in SQL server management studio. I think what I'm trying can be done, is this the right way?

Thanks.

It looks like all the stored-procedure is doing is building the variable @sql.

Try adding this at the bottom of the stored-procedure:

EXEC @sql
