Can I use custom query in DB Adapter with Polling

Question

Hi All,
I am getting problem while using db adapter with polling. Can I use custom query in db adapter with polling.
I am using 2 tables; table 1 and table2
Structure of table1 is as:
File_name
Batch_id
Creation_date
Status
Structure of table2 is as:
Batch_id
Employee_ID
Last_Name
First_Name
Middle_Name
Group_ID
Site_ID
Dept_Num
Report_id
I have to use below query while polling to table1
Select count(*) as NOSEXP, Report_id
from table1, table2
where table2.batch_id =
table2.batch_id
and table1.Status= 0
group by Report_id;
I mean, when I use DB adapter to poll table1, I have to use above query.
Can you Please suggest on this.
Thanks in advance.

Answer 1

I will check for existance not based on Primary key but based on three other fields in the table. I think , by default DB adapter configured for MERGE checks for existance based on PK. Can we change the Primary Key in the mapping file after the DB adapter is configured. In that case , will it check for existance based on the fields , I mention.
