rowid is not an indexed column - it is a "pseudocolumn'.
By definition, rowids are the physical address of each row, thus it is also an index.

It is also important to note that the database server does not assign rowids to rows
in fragmented tables.

mssql_fetch_row - Get row as enumerated array

SYNOPSIS
array mssql_fetch_row (resource $result) DESCRIPTION
mssql_fetch_row(3) fetches one row of data from the result associated with the specified result identifier. The row is returned as an array. Each result column is stored in an array offset, starting at offset 0. Subsequent call to mssql_fetch_row(3) would return the next row in the result set, or FALSE if there are no more rows. PARAMETERS
o $result - The result resource that is being evaluated. This result comes from a call to mssql_query(3). RETURN VALUES
Returns an array that corresponds to the fetched row, or FALSE if there are no more rows. EXAMPLES
Example #1 mssql_fetch_row(3) example <?php // Connect to MSSQL and select the database $link = mssql_connect('MANGOSQLEXPRESS', 'sa', 'phpfi'); mssql_select_db('php', $link); // Query to execute $query = mssql_query('SELECT [id], [quote] FROM [quotes] WHERE [id] = '42'', $link); // Did the query fail? if (!$query) { die('MSSQL error: ' . mssql_get_last_message()); } // Fetch the row $row = mssql_fetch_row($query); // Print the 'quote' echo 'Quote #' . $row[0] . ': "' . $row[1] . '"'; ?> The above example will output something similar to: Quote #42: "The answer to everything..." NOTES
