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

说明

sqlsrv_fetch ( resource $stmt [, int $row [, int $offset ]] ) : mixed

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

参数

stmt

A statement resource created by executing sqlsrv_query() or sqlsrv_execute().

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:

• SQLSRV_SCROLL_NEXT
• SQLSRV_SCROLL_PRIOR
• SQLSRV_SCROLL_FIRST
• SQLSRV_SCROLL_LAST
• SQLSRV_SCROLL_ABSOLUTE
• SQLSRV_SCROLL_RELATIVE

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 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.

范例

Example #1 sqlsrv_fetch() example

The following example demonstrates how to retrieve a row with sqlsrv_fetch() and get the row fields with sqlsrv_get_field().

<?php$serverName = "serverName\sqlexpress";$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( $stmt ) === false) {     die( print_r( sqlsrv_errors(), true));}// Get the row fields. Field indices start at 0 and must be retrieved in order.// Retrieving row fields by name is not supported by sqlsrv_get_field.$name = sqlsrv_get_field( $stmt, 0);echo "$name: ";$comment = sqlsrv_get_field( $stmt, 1);echo $comment;?>
