sqlsrv_fetch

SQL Server 2008 R2

Makes the next row of a result set available for reading. Use sqlsrv_get_field to read fields of the row.

sqlsrv_fetch( resource $stmt[, row[, ]offset])

$stmt: A statement resource corresponding to an executed statement.

Note Note

A statement must be executed before results can be retrieved. For information on executing a statement, see sqlsrv_query and sqlsrv_execute.

row [OPTIONAL]: One of the following values, specifying the row to access in a result set that uses a scrollable cursor:

  • SQLSRV_SCROLL_NEXT

  • SQLSRV_SCROLL_PRIOR

  • SQLSRV_SCROLL_FIRST

  • SQLSRV_SCROLL_LAST

  • SQLSRV_SCROLL_ABSOLUTE

  • SQLSRV_SCROLL_RELATIVE

For more information on these values, see Specifying a Cursor Type and Selecting Rows.

offset [OPTIONAL]: Used with SQLSRV_SCROLL_ABSOLUTE and SQLSRV_SCROLL_RELATIVE to specify the row to retrieve. The first record in the result set is 0.

If the next row of the result set was successfully retrieved, true is returned. If there are no more results in the result set, null is returned. If an error occurred, false is returned.

The following example uses sqlsrv_fetch to retrieve a row of data containing a product review and the name of the reviewer. To retrieve data from the result set, sqlsrv_get_field is used. The example assumes that SQL Server and the AdventureWorks database are installed on the local computer. All output is written to the console when the example is run from the command line.

<?php
/*Connect to the local server using Windows Authentication and
specify the AdventureWorks database as the database in use. */
$serverName = "(local)";
$connectionInfo = array( "Database"=>"AdventureWorks");
$conn = sqlsrv_connect( $serverName, $connectionInfo);
if( $conn === false )
{
     echo "Could not connect.\n";
     die( print_r( sqlsrv_errors(), true));
}

/* Set up and execute the query. Note that both ReviewerName and
Comments are of SQL Server type nvarchar. */
$tsql = "SELECT ReviewerName, Comments 
         FROM Production.ProductReview
         WHERE ProductReviewID=1";
$stmt = sqlsrv_query( $conn, $tsql);
if( $stmt === false )
{
     echo "Error in statement preparation/execution.\n";
     die( print_r( sqlsrv_errors(), true));
}

/* Make the first row of the result set available for reading. */
if( sqlsrv_fetch( $stmt ) === false)
{
     echo "Error in retrieving row.\n";
     die( print_r( sqlsrv_errors(), true));
}

/* Note: Fields must be accessed in order.
Get the first field of the row. Note that no return type is
specified. Data will be returned as a string, the default for
a field of type nvarchar.*/
$name = sqlsrv_get_field( $stmt, 0);
echo "$name: ";

/*Get the second field of the row as a stream.
Because the default return type for a nvarchar field is a
string, the return type must be specified as a stream. */
$stream = sqlsrv_get_field( $stmt, 1, 
                            SQLSRV_PHPTYPE_STREAM( SQLSRV_ENC_CHAR));
while( !feof( $stream ))
{ 
    $str = fread( $stream, 10000);
    echo $str;
}

/* Free the statement and connection resources. */
sqlsrv_free_stmt( $stmt);
sqlsrv_close( $conn);
