Exporting 10 million records to a flat file and processing that is unlikely to be faster than just doing it in SQL, at least if the relevant columns are indexed. Have you checked your query with explain plan or similar to see if you can optimise it at all?

mssql_query
MSSQL_QUERY(3) MSSQL_QUERY(3)
mssql_query - Send MS SQL query
SYNOPSIS
mixed mssql_query (string $query, [resource $link_identifier], [int $batch_size])
DESCRIPTION
mssql_query(3) sends a query to the currently active database on the server that's associated with the specified link identifier.
PARAMETERS
o $query
- An SQL query.
o $link_identifier
- A MS SQL link identifier, returned by mssql_connect(3) or mssql_pconnect(3). 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(3) was called, and use it.
o $batch_size
- The number of records to batch in the buffer.
RETURN VALUES
Returns a MS SQL result resource on success, TRUE if no rows were returned, or FALSE on error.
EXAMPLES
Example #1
mssql_query(3) 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);
?>
NOTES
Note
If the query returns multiple results then it is necessary to fetch all results by mssql_next_result(3) or free the results by
mssql_free_result(3) before executing next query.
SEE ALSO
mssql_select_db(3), mssql_connect(3).
