The data retrieval response document has a format similar to the data load response document—as explained in Load Request Document Format—but it is easier to parse. The general format of a retrieval response document looks as follows:
<rowsets>tag: This is the root element of a retrieval response document. Its children are:<rowset>tag: One<rowset>tag for each<free-query>tag sent in the request<error>tag
<rowset>tag: Each<rowset>tag gets the same ID as the<free-query>tag in the retrieval request document to indicate to which query this rowset replies.<error>tag: This tag contains a complete description of the error. It is a required tag indicating whether a problem has occurred on rowset level. Errors on rowset level mostly point out problems in the RDBMS.
