Need help in webservice to JDBC scenario

Question

Hi All,
My scenario is a synchronous webservice to JDBC scenario. The SOAP request contains two fields one is ID & the other field is Date which is an optional field. I need to perform a SELECT statement on JDBC based on ID & Date. SOAP request will always contain ID field & Date may or maynot be there in the request. If Date present then search should be based on ID & Date , if Date not present search should be based on ID only. How to achieve this with the help of standard JDBC reciever structure or is there any other way to achieve this?
Thanks
Navin

Answer 1

You can create your target structure as shown below and check the existence of DATE field in the source(using standard function "Exists" ) and then only create the target DATE node.
<StatementName>
          <dbTableName action=u201DSELECTu201D>
              <table>realDbTableName</table>
              <access>
                  <col1/>
                 <col2/>
                 <col3/>
              </access>
              <key1>
                 <DATE/>
                 <ID/>
              </key1>
          </dbTableName>
   </StatementName>
