Issue with DB Adapter involving multiple tables

Question

Hi,
Am facing an issue with DB Adapter with multiple tables. Here are the details.
I have 4 tables. Header, Details,Products and Devices. The relationship is defined as follows:
Header has 1:M relationship with Details.
Details has 1:M relationship with Products.
Products has 1:M relationship with Devices.
I want to select the details from all the tables for a particular header_id and detail_id. Defined 2 parameters and query is created with parameters.
SELECT DISTINCT t0.FILE_NAME, t0.UNIQUE_SEQUENCE_NUMBER, t0.HEADER_COUNT, t0.TOTAL_DEVICE_COUNT, t0.FILE_DATE, t0.FILE_SEQ_NUMBER, t0.DEVICE_COUNT, t0.PHONE_TYPE, t0.PHONE_OWNERSHIP, t0.TRANSACTION_TYPE, t0.PURCHASE_ORDER_NUMBER, t0.CUSTOMER_ID, t0.CUSTOMER_DEST_SUFFIX, t0.LOCATION_DESTINATION, t0.MASTER_FACTORY_ORDER, t0.MASTER_FACTORY_ORDER_LINE_NUM, t0.ENT_ORDER_NUMBER, t0.DELIVERY_IDENTIFICATION_NUM, t0.UEDF_REVISION_NUM, t0.STATUS, t0.INBOUND_BPEL_INSTANCE_ID, t0.ERROR_DESCRIPTION, t0.INBOUND_FILE_VERSION, t0.CREATED_BY, t0.CREATION_DATE, t0.UPDATED_BY, t0.UPDATE_DATE FROM EDF_HEADER_STG_INT t0, EDF_DETAILS_STG_INT t1 WHERE (((t0.FILE_NAME = #file_name) AND (t1.EDF_SERIAL_TYPE = #prod_type)) AND (t1.UNIQUE_SEQUENCE_NUMBER = t0.UNIQUE_SEQUENCE_NUMBER))
I expect the DB Adapter to retrieve the records for the parameters passed. i.e only those records from details table which matches with the parameter I passes in (t1.EDF_SERIAL_TYPE = #prod_type) . But I see that the DB Adapter retrieves all records from the details table for a particular unique_sequence_number(unique_sequence_number is primary key for headers table and foreign key for details table). Could you pls tell me how can I retrieve only selected records from the details table?

Answer 1

Yes. When I run this query in DB, I get one record . While defining DB Adapter, I have imported 4 tables and also defined the relationship between the tables. In my case, column unique sequence number is primary key of headers table and foreign key of details table.The above select query is generated by the DB Adapter for the parameters I have passed in.
My data is as follows:
Headers table:
file_name uniq_seq_num
file_1.xml 220
Details table
product_id unique seq num edf_prod_type
111 220 A
112 220 B
113 220
Now, I call DB Adapter with parameters 'file_1.xml' (file_name)and 'A'(prod_type). I expect the DB adapter to retrieve only one record with product_id 111 in the detailscollection. But I see that the adapter retrieves all records from the details table without considering the value of prod_type.
