mssql_query — Send MS SQL query

说明

mixed mssql_query ( string $query [, resource $link_identifier [, int $batch_size = 0 ]] )

mssql_query() sends a query to the currently active database on the server that's associated with the specified link identifier.

参数

query

An SQL query.

link_identifier

A MS SQL link identifier, returned by mssql_connect() or mssql_pconnect().

If the link identifier isn't specified, the last opened link is assumed. If no link is open, the function tries to establish a link as if mssql_connect() was called, and use it.

batch_size

The number of records to batch in the buffer.

返回值

Returns a MS SQL result resource on success, TRUE if no rows were returned, or FALSE on error.

范例

Example #1 mssql_query() example


<?php
// Connect to MSSQL
$link = mssql_connect('KALLESPCSQLEXPRESS', 'sa', 'phpfi');

if (!$link || !mssql_select_db('php', $link)) {
    die('Unable to connect or select database!');
}

// Do a simple query, select the version of 
// MSSQL and print it.
$version = mssql_query('SELECT @@VERSION');
$row = mssql_fetch_array($version);

echo $row[0];

// Clean up
mssql_free_result($version);
?>

注释

Note:

If the query returns multiple results then it is necessary to fetch all results by mssql_next_result() or free the results by mssql_free_result() before executing next query.
