sqlsrv_fetch_array — Returns a row as an array


Описание

array sqlsrv_fetch_array ( resource $stmt [, int $fetchType [, int $row [, int $offset ]]] )

Returns the next available row of data as an associative array, a numeric array, or both (the default).


Список параметров

stmt -

A statement resource returned by sqlsrv_query or sqlsrv_execute.

fetchType -

A predefined constant specifying the type of array to return. Possible values are SQLSRV_FETCH_ASSOC, SQLSRV_FETCH_NUMERIC, and SQLSRV_FETCH_BOTH (the default).

A fetch type of SQLSRV_FETCH_ASSOC should not be used when consuming a result set with multiple columns of the same name.

row -

Specifies the row to access in a result set that uses a scrollable cursor. Possible values are SQLSRV_SCROLL_NEXT, SQLSRV_SCROLL_PRIOR, SQLSRV_SCROLL_FIRST, SQLSRV_SCROLL_LAST, SQLSRV_SCROLL_ABSOLUTE and, SQLSRV_SCROLL_RELATIVE (the default). When this parameter is specified, the fetchType must be explicitly defined.


Возвращаемые значения

Returns an array on success, NULL if there are no more rows to return, and FALSE if an error occurs.


Примеры

Пример #1 Retrieving an associative array.
$serverName = "serverName\instanceName";
$connectionInfo = array( "Database"=>"dbName", "UID"=>"username", "PWD"=>"password");
$conn = sqlsrv_connect( $serverName, $connectionInfo );
if( $conn === false ) {
    die( print_r( sqlsrv_errors(), true));
}
$sql = "SELECT FirstName, LastName FROM SomeTable";
$stmt = sqlsrv_query( $conn, $sql );
if( $stmt === false) {
    die( print_r( sqlsrv_errors(), true) );
}
while( $row = sqlsrv_fetch_array( $stmt, SQLSRV_FETCH_ASSOC) ) {
      echo $row['LastName'].", ".$row['FirstName']."<br />";
}
sqlsrv_free_stmt( $stmt);

Пример #2 Retrieving a numeric array.
$serverName = "serverName\instanceName";
$connectionInfo = array( "Database"=>"dbName", "UID"=>"username", "PWD"=>"password");
$conn = sqlsrv_connect( $serverName, $connectionInfo );
if( $conn === false ) {
    die( print_r( sqlsrv_errors(), true));
}
$sql = "SELECT FirstName, LastName FROM SomeTable";
$stmt = sqlsrv_query( $conn, $sql );
if( $stmt === false) {
    die( print_r( sqlsrv_errors(), true) );
}
while( $row = sqlsrv_fetch_array( $stmt, SQLSRV_FETCH_NUMERIC) ) {
      echo $row[0].", ".$row[1]."<br />";
}
sqlsrv_free_stmt( $stmt);


Примечания

Not specifying the fetchType or explicity using the SQLSRV_FETCH_TYPE constant in the examples above will return an array that has both associative and numeric keys.

If more than one column is returned with the same name, the last column will take precedence. To avoid field name collisions, use aliases.

If a column with no name is returned, the associative key for the array element will be an empty string ("").
