<P>
A custom Velocity directive to create a PreparedStatement parameter text. There are the
following possible invocation formats inside the template:
<pre>
#bind(value) - e.g. #bind($xyz)
#bind(value jdbc_type_name) - e.g. #bind($xyz 'VARCHAR'). This is the most common and useful form.
#bind(value jdbc_type_name, scale) - e.g. #bind($xyz 'VARCHAR' 2)
</pre>
<p>
Other examples:
</p>
<p>
<strong>Binding literal parameter value:</strong>
</p>
<p>
<code>"WHERE SOME_COLUMN > #bind($xyz)"</code> produces
<code>"WHERE SOME_COLUMN > ?"</code> and also places the value of the "xyz" parameter
in the context "bindings" collection.
</p>
<p>
<strong>Binding ID column of a DataObject value:</strong>
</p>
<p>
<code>"WHERE ID_COL1 = #bind($helper.cayenneExp($xyz, 'db:ID_COL2'))
AND ID_COL2 = #bind($helper.cayenneExp($xyz, 'db:ID_COL2'))"</code> produces <code>"WHERE ID_COL1 = ? AND ID_COL2 = ?"</code> and also places the
values of id columns of the DataObject parameter "xyz" in the context "bindings"
collection.
