Reg: SQL select Query in BPEL process flow

Question

<p>
Hi,
I am suppose to execute a SQL select query (in BPEL Process flow) as mention below in JDeveloper using Database adapter.
</p>
<p>
SELECT LENGTH, WIDTH, HEIGHT, WEIGHT,
</p>
<p>
LENGTH*WIDTH* HEIGHT AS ITEM_CUBE
</p>
<p>
FROM CUBE
</p>
<p>
WHERE ITEM= &lt;xyz&gt;
</p>
<p>
AND OBJECT= (SELECT CASE_NAME FROM CUBE_SUPPLIER WHERE ITEM=&lt;xyz&gt; AND SUPP_IND = &lsquo;Y')
<strong>Now my question is:
1.</strong> What does this "*" refer to in the query and how can I retrieve the value of LENGTH*WIDTH* HEIGHT from the query where LENGTH,WIDTH and HEIGHT are the individual field in the table.
2.What does this " AS" refer to? If " ITEM_CUBE " is the alies for the table name "ITEM" to retrieve the value, then query shoud be evaluated as
</p>
<p>
SELECT LENGTH, WIDTH, HEIGHT, WEIGHT,
</p>
<p>
LENGTH*WIDTH* HEIGHT AS ITEM_CUBE
</p>
<p>
FROM CUBE
</p>
<p>
WHERE <strong>ITEM_CUBE.ITEM</strong>= &lt;xyz&gt;
</p>
<p>
AND <strong>ITEM_CUBE.OBJECT</strong>= (SELECT CASE_NAME FROM CUBE_SUPPLIER WHERE ITEM=&lt;xyz&gt; AND SUPP_IND = &lsquo;Y')
Is my assumption correct?
Please suggest asap.
Thanks...

Answer 1

Hi
Thank for your reply!
I have a nested select query which performs on two different table as shown below:
<p>
SELECT LENGTH, WIDTH, HEIGHT, WEIGHT,
</p>
<p>
LENGTH*WIDTH* HEIGHT AS ITEM_CUBE
</p>
<p>
FROM CUBE
</p>
<p>
WHERE ITEM= &lt;abc&gt;
</p>
<p>
AND OBJECT= (SELECT NAME FROM SUPPLIER WHERE ITEM=&lt;Item&gt; AND SUPP_IND = &lsquo;Y')
I am using DB adapter of Oracle JDeveloper in BPEL process flow, where I can able to select only one master table in DB adapter say SUPPLIER and its attributes at a time.But as per my requirment I need to select both the table (CUBE and SUPPLIER) in a single adapter to execute my query.
It can be achievable by using two DB adapter , One to execute the nested query and another to execute the main qyery considering value of nested query as a parameter.But I want to achieve it by using a single one.
Am I correct with my concept?
Please suggest how to get it ?
</p>
