sqlsrv_fetch_array — Returns a row as an array

说明

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

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

参数

stmt

A statement resource returned by sqlsrv_query or sqlsrv_prepare.

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.

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.

返回值

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

范例

Example #1 Retrieving an associative array.

<?php
$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);
?>

Example #2 Retrieving a numeric array.

<?php
$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);
?>

注释

Not specifying the fetchType or explicitly 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 ("").
