><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 <cod

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 component expects an iterator that contains the
parameter iterators; the size of the outer iterator determines the batch
size.</p><p>From Camel 2.16 onwards you can use the
option <span>useMessageBodyForSql that allows to use the message body as
the SQL statement, and then the SQL parameters must be provided in a header
with the key SqlConstants.SQL_PARAMETERS. This allows the SQL component to
work more dynamic as the SQL query is from the message body.</span></p><h3

>id="BookComponentAppendix-Treatmentofthemessagebody">Treatment o
f 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 component expects an iterator that contains the
parameter iterators; the
size of the outer iterator determines the batch size.</p><p>From Camel 2.16
onwards you can use the option <span>useMessageBodyForSql that allows to
use the message body as the SQL statement, and then the SQL parameters must be
provided in a header with the key SqlConstants.SQL_PARAMETERS. This allows
the SQL component to work more dynamic as the SQL query is from the message
body.</span></p><h3 id="BookComponentAppendix-Resultofthequery">Result of the
query</h3><p>For <code>select</code> operations, the result is an instance of
<code>List<Map<String, Object>></code> type, as returned by the <a

rel="nofollow">JdbcTemplate.queryForList()</a> method. For <code>update</code>
operations, the result is the number of updated rows, returned as an
<code>Integer</code>.
</p><p>By default, the result is placed in the message body.  If the
outputHeader parameter is set, the result is placed in the header.  This
is an alternative to using a full message enrichment pattern to add headers, it
provides a concise syntax for querying a sequence or some other small value
into a header.  It is convenient to use outputHeader and outputType
together:</p><div class="code panel pdl" style="border-width: 1px;"><div
