sqlsrv_fetch - Makes the next row in a result set available for reading

SYNOPSIS
mixed sqlsrv_fetch (resource $stmt, [int $row], [int $offset]) DESCRIPTION
Makes the next row in a result set available for reading. Use sqlsrv_get_field(3) to read the fields of the row. PARAMETERS
o $stmt - A statement resource created by executing sqlsrv_query(3) or sqlsrv_execute(3). o $row - The row to be accessed. This parameter can only be used if the specified statement was prepared with a scrollable cursor. In that case, this parameter can take on one of the following values: oSQLSRV_SCROLL_NEXT oSQLSRV_SCROLL_PRIOR oSQLSRV_SCROLL_FIRST oSQLSRV_SCROLL_LAST oSQLSRV_SCROLL_ABSOLUTE oSQLSRV_SCROLL_RELATIVE o $offset - Specifies the row to be accessed if the row parameter is set to SQLSRV_SCROLL_ABSOLUTE or SQLSRV_SCROLL_RELATIVE. Note that the first row in a result set has index 0. RETURN VALUES
Returns TRUE if the next row of a result set was successfully retrieved, FALSE if an error occurs, and NULL if there are no more rows in the result set. EXAMPLES
Example #1 sqlsrv_fetch(3) example The following example demonstrates how to retrieve a row with sqlsrv_fetch(3) and get the row fields with sqlsrv_get_field(3). <?php $serverName = "serverNamesqlexpress"; $connectionInfo = array( "Database"=>"dbName", "UID"=>"username", "PWD"=>"password"); $conn = sqlsrv_connect( $serverName, $connectionInfo); if( $conn === false ) { die( print_r( sqlsrv_errors(), true)); } $sql = "SELECT Name, Comment FROM Table_1 WHERE ReviewID=1"; $stmt = sqlsrv_query( $conn, $sql); if( $stmt === false ) { die( print_r( sqlsrv_errors(), true)); } // Make the first (and in this case, only) row of the result set available for reading. if( sqlsrv_fetch( $stmt ) === false) { die( print_r( sqlsrv_errors(), true)); } // Get the row fields. Field indeces start at 0 and must be retrieved in order. // Retrieving row fields by name is not supported by sqlsrv_get_field. $name = sqlsrv_get_field( $stmt, 0); echo "$name: "; $comment = sqlsrv_get_field( $stmt, 1); echo $comment; ?> SEE ALSO
