<div class="">You don’t need a variable if you don’t
care about the return value of the function you are
calling.</div>
<div class=""><br class="">
</div>
<div class="">To be clear, your problem with the
badmatch is due to Db2 already having a value assigned
which is not equal to the atom ‘ok’.</div>
<div class=""><br class="">
</div>
<div class="">Try this at the shell to see what that
value is:</div>
<div class=""><br class="">
</div>
<div class=""> <span class="Apple-converted-space"> </span>Db2.
% don’t forget the period there</div>
<div class=""><br class="">
</div>
<div class="">More than likely it is set to {ok}, which
is what you previously had db:destroy/1 returning.</div>
<div class=""><br class="">
</div>
<div class="">Since erlang is a single-assignment
language, you cannot simply assign a different value
to Db2 once it is bound.</div>
<div class=""><br class="">
</div>
<div class="">You *can* use syntax that appears just
like an assignment and have that work, provided the
value returned from the function matches exactly the
value currently bound to the variable on the left-hand
side of the “=“.</div>

<div class=""><br class="">
</div>
<div class="">Here’s what’s going on there:</div>
<div class=""><br class="">
</div>
<div class="">1. I bound the value {ok} to the variable
Db2</div>
<div class=""><br class="">
</div>
<div class="">2. I check the value of Db2</div>
<div class=""><br class="">
</div>
<div class="">3. I “assign” Db2 the same value — this
isn’t really an assignment now, it is a match, and in
this case both the left-hand side and right-hand side
have same value, so match succeeds</div>
<div class=""><br class="">
</div>
<div class="">4. I attempt to assign Db2 a different
value—since Db2 was bound to {ok} and the right-hand
side now has ‘ok’, that match fails—thus the match
error</div>
<div class=""><br class="">
</div>
<div class="">5. I “assign” Db2 the original value —
again, this isn’t really an assignment, it is a match,
which again succeeds for same reason as (3) above</div>
<div class=""><br class="">
</div>
<div class="">6. I use the f() function at the shell to
“forget” about the value previously bound to Db2,
effectively making Db2 unbound to any value (and as
such it can now be assigned any value)</div>
<div class=""><br class="">
</div>
<div class="">7. I assign a different value, this time
‘ok’, to Db2 — no errors that time, because it was an
assignment, not a match</div>
<div class=""><br class="">
</div>
<div class="">8. I attempt to match Db2 with the
previous value—and there’s that match error again</div>
<div class=""><br class="">
</div>
<div class="">9. I “assign” Db2 the new value again—now
it is a match, and the match is good so no error</div>
<div class=""><br class="">
</div>
<div class=""><br class="">
</div>
<div class="">Does that make sense now?</div>
