Retrieving output parameter from SQL server stored procedure

Recommended Posts

 How to retrieve a table output parameter from sql server stored procedure to php variable? 

 

I've the following code that returns a table from the query. The table needs to be retrieved in PHP and formatted before being printed onto a file. 

 

## Stored Procedure: 

 

 @query1 has a table from select statement that is pivoted. 

 

       EXEC SP_EXECUTESQL @query= @query1, @params= N'@queryO NVARCHAR(MAX) OUTPUT', @queryO= @queryO OUTPUT; 

 
       declare @getProducts NVARCHAR(MAX) 
 
       select @getProducts= @queryO; 
 
## The PHP code follows: 

   

    $stmt2 = sqlsrv_query($conn, $tsql_createSP);
 
    if( $stmt2 === false )
    {
    echo "Error in executing statement 2.\n";
    die( print_r( sqlsrv_errors(), true));
    }
 
   $getProducts="ABCD";
 
  $params = array(
  array($chrom_set,SQLSRV_PARAM_IN),
  array($getProducts,SQLSRV_PARAM_OUT)
  );
 
  $tsql_callSP = "{call spGetPivot( ?,? OUTPUT)}";
 
  $stmt3 = sqlsrv_query($conn,$tsql_callSP,$params);
 
 
  if ( $stmt3 === false) { echo "Error in executing statement 3.\n";
        die( FormatErrors( sqlsrv_errors() ) );}
 
  $productCount = 0;     
 
  function cleanData($str)
  {
    $str = preg_replace("/\t/", "\\t", $str);
    $str = preg_replace("/\r?\n/", "\\n", $str);
    $str=str_replace("\\n","",$str);
    if(strstr($str, '"')) $str = '"' . str_replace('"', '""', $str) . '"';
  }
 
 // file name for download
  
  $filename = "NAM_data_" . date('YmdHis') ."_pg".".txt";
 
  header("Content-Disposition: attachment; filename=\"$filename\"");
  header("Content-Type: text/plain");
 
  $flag = false;
 
  while( $row = sqlsrv_fetch_array( $getProducts, SQLSRV_FETCH_ASSOC)){
    
  if(!$flag){
      // display field/column names as first row
 
      array_walk($row, 'cleanData');
      echo implode("\t", array_keys($row)) . "\r\n";
      $flag = true;
    }
    array_walk($row, 'cleanData');
    echo implode("\t", array_values($row)). "\r\n";
  } 
  
   sqlsrv_free_stmt( $stmt1);
   sqlsrv_free_stmt( $stmt2);
   sqlsrv_free_stmt( $stmt3);
   sqlsrv_close( $conn);
 
I'm not able to retrieve the output with this code. The query works well in this format in SSMS.
