JDBC adapter to SAP: select & join from multiple tables ???

Question

Hello,
I have a task to get an aggregating information from two tables and send it into SAP.
I use XI JDBC sender adapter to access to MSSQL DB.
I know how to construct SQL quiery:
(something like that)
SELECT  table1.Date  SUM(table1.sum) from table1
INNER JOIN table2
ON table1.Number = table2.Number
But I don't understand how to construct  Data Type for this complex select operator?
How does it look like?
Where to store and how to map the selected data?
Please give me an example or an advice.
Thank You.

Hi,
Use your structure like this.
<StatementName4>
<dbTableName action=”SELECT”>
<table>realDbTableName</table>
<access>
<col1/>
<col2/>
<col3/>
</access>
<key1>
<col2>val2old</col2>
<col4>val4</col4>
</key1>
<key2>
<col2>val2old2</col2>
</key2>
</dbTableName>
</StatementName4>
action=SELECT
Statements with this action cause existing table values to be selected. Therefore, the statement corresponds to an SQL SELECT statement.
The <access> block contains the column names to be selected, a <key> element contains the columns whose values must be identical with the specified value to get the new column values. The name of the <key> element is arbitrary. Column values within a <key> element are combined with a logical AND; different <key> elements are combined with a logical OR.
A statement with the action SELECT must have exactly one <access> element. The number of <key> elements with arbitrary names is not restricted.
The corresponding SQL statement for StatementName4 in the example above is as follows:
SELECT col1,col2,col3 FROM dbTableName WHERE ((col2=’val2old’ AND col4=’val4’) OR (col2=’val2old2’))
If there is no <key> element, or if there is a <key> element but it is empty, then no condition is specified and the entire table is to be selected. This may not be permitted by the configuration of the JDBC adapter for security reasons and will therefore result in an error during message processing and an appropriate error message.
The response document contains the result of the action in XML format as follows:
<row>
<column1>value11</column1>
<column2>value12</column2>
</row>
<row>
<column1>valueN1</column1>
<column2>valueN2</column2>
</row>
This will help you.
