mssql_query — Send MS SQL query

Warning

This function was REMOVED in PHP 7.0.0.

Alternatives to this function include:

- PDO::query()
- sqlsrv_query()
- odbc_exec()

### 说明

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

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('KALLESPC\SQLEXPRESS', '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.
