SQL XML Document format - Sequence of excecution for the sentences

Question

Hi, I am using XML SQL Document format to send actions to an Oracle database.
My concern is this:  I need to insert several invoice header lines then after that I need to insert the Invoice position lines and then, at the end, i need to excecute an store procedure.
If I do all that in one message, each sentence is treated by the DB in order  ? or is it treated  in paralel?
It is possible to excecute StatementName1 StatementName2 and StatementName3 in that exact order?
An example of the xml message is this...
<Message>
<StatementName1>
<dbTableName action=u201DINSERTu201D>
<table>TABLE1</table>
<access>
<col1>val1</col1>
<col2>val2</col2>
</access>
<access>
<col1>val11</col1>
</access>
</dbTableName>
</StatementName1>
<StatementName2>
<dbTableName action=u201DINSERTu201D>
<table>TABLE2</table>
<access>
<col1>val1</col1>
<col2>val2</col2>
</access>
<access>
<col1>val11</col1>
</access>
</dbTableName>
</StatementName2>
<StatementName3>
<storedProcedureName action=u201D EXECUTEu201D>
<table>realStoredProcedureeName</table>
<param1 [isInput=u201Dtrueu201D] [isOutput=true] type=SQLDatatype>val1</param1>
</storedProcedureName >
</StatementName3>
</Message>

Answer 1

I just want to clarify I need to execute the sentences serially, also i am using a JDBC adapter in XI to do the connection.
On the other hand I believe the order of excecution has relation with the DB and not with the SAP program, because once the message is received by de DB, how it treats it is a responsability of the DB.
