-</div><h3 id="BookInOnePage-Treatmentofthemessagebody">Treatment of the
message body</h3><p>The SQL component tries to convert the message body to an
object of <code>java.util.Iterator</code> type and then uses this iterator to
fill the query parameters (where each query parameter is represented by a
<code>#</code> symbol (or configured placeholder) in the endpoint URI). If the
message body is not an array or collection, the conversion results in an
iterator that iterates over only one object, which is the body
itself.</p><p>For example, if the message body is an instance of
<code>java.util.List</code>, the first item in the list is substituted into the
first occurrence of <code>#</code> in the SQL query, the second item in the
list is substituted into the second occurrence of <code>#</code>, and so
on.</p><p>If <code>batch</code> is set to <code>true</code>, then the
interpretation of the inbound message body changes slightly – instead of
an iterator of parameters, the compon
ent expects an iterator that contains the parameter iterators; the size of the
outer iterator determines the batch size.</p><h3

id="BookInOnePage-Treatmentofthemessagebody">Treatment of the message
body</h3><p>The SQL component tries to convert the message body to an object of
<code>java.util.Iterator</code> type and then uses this iterator to fill the
query parameters (where each query parameter is represented by a <code>#</code>
symbol (or configured placeholder) in the endpoint URI). If the message body is
not an array or collection, the conversion results in an iterator that iterates
over only one object, which is the body itself.</p><p>For example, if the
message body is an instance of <code>java.util.List</code>, the first item in
the list is substituted into the first occurrence of <code>#</code> in the SQL
query, the second item in the list is substituted into the second occurrence of
<code>#</code>, and so on.</p><p>If <c
ode>batch</code> is set to <code>true</code>, then the interpretation of the
inbound message body changes slightly – instead of an iterator of
parameters, the component expects an iterator that contains the parameter
iterators; the size of the outer iterator determines the batch size.</p><h3
