<p>
As an example, consider following index on integer attributes.

<tt>SQL&gt;create index X on T (A, B, C) nologging;</tt>

Single range scan means that bounds are set on

For example following scans are supported (the last 2 not via NDB ODBC).
<p>
<tt>SQL&gt;select * from T where A = 1;</tt>
<br>
<tt>SQL&gt;select * from T where A = 1 and B = 10 and C = 20;</tt>
