Build a JDBCBlob object.
 

1 blob

<blob>
    <blob /> ?
</blob>

Improving

After the upgrade it is possible to directly add a file, without using blob.append.

Before:

Copy
<set name='my_blob'><blob/></set>
<blob.append><my_blob/><file name='my_file' /></blob.append>

Now:

Copy
<set name='my_blob'><blob><file name='my_file' /><blob></set>
Example
Copy
<xsql-script>
    <body>
        <set name='m_blob'><blob /></set>
        <foreach>
           
            <select prefix='m_'>
                <columns>
                    apps_sfa_task_resl_bytes.ask_code, apps_sfa_task_resl_bytes.response_content_type, apps_sfa_task_resl_bytes.response_chunk, apps_sfa_task_resl_bytes.response_bytes
                </columns>
                <from table='apps_sfa_task_resl_bytes' />
                <where>
                    apps_sfa_task_resl_bytes.assign_user   = 'android'    AND
                    apps_sfa_task_resl_bytes.assign_type   = 0            AND
                    apps_sfa_task_resl_bytes.assign_number = 83           AND
                    apps_sfa_task_resl_bytes.task_code     = 'TEST_BYTES' AND
                    apps_sfa_task_resl_bytes.ask_code      = 'PR2'
                </where>
                <order>ask_code, response_chunk</order>

                <blob.append><m_blob/><m_response_bytes /></blob.append>
            </do>

        </foreach>

      <println>
          LENGTH = <blob.length><m_blob /></blob.length> <m_response_content_type />
