Limiting the Fetch Size

[Ram Chhabra]

Hi,

I need to check that does something exist in some specified table or not. For that i can run query like

  select * from mytable  

... but my problem is that mytable consist 10 Lakhs of records.

I only need to check that is any single record exist or not.... Can i use setFetchSize() or something else... can you please suggest what policy should i opt to improve performance

Thanks

Why not limit your results set by specifying conditions in a where or having clause?

(also, what's a Lakh?)

Thanks for your answer. After putting where clause also i am having 1 million of records. Then how to restrict.

How about choosing conditions that limit your result set to a smaller size?

If I remember correctly lakh = 100,000.
