Tips:
The USING statement can also be useful even for simple DATA
statements, if you are doing map queries. It was previously recommended to add
an index on the oid column of tables used in query-able layers, in order to
speed up the performance of map queries. However, with the USING clause, it is
possible to tell mapserver to use your table’s primary key as the identifier for
map queries, and then it is no longer necessary to have an additional
index.
