Howard Chu writes "Hi there,
I'm writing the search engine... the select result returns n records. However, I just want each subset of the result at the time. How can I slice and just get a piece of the result with lower range and upper range
For example:
Result returns 500 rows.
I want the page display 20 rows at a time.
First, I just want to have the first 20 rows (1-20).
Then if user click Next, I run the query again and want to have the next 20 rows (21-40)
I can do slice in my script... but it's costly to transfer all the time 500 rows while I need only 20 rows
In Oracle, I used 'row_number' and 'between'.... Is there any equivalent in SQL
Thanks,
-Howard" |
