It can also work in SQL Server. PL/SQL Bulk Collect With LIMIT Clause In Oracle Database. where ROWNUM <= : MAX_ROW_TO_FETCH) where rnum >= : MIN_ROW_TO_FETCH; (Copied from specified AskTom-article): Starting with Oracle 12c (12.1) there is a syntax available to limit rows or start at offsets. For example, the following statement gets the top five employees with the highest salaries. It’s a bit more complicated, as you’ll need to use RANK as an analytic function, but the query works. Oracle SQL: select first n rows / rows between n and m (top n/limit queries) At times, it's necessary to select the first n rows or the rows between n and m (paging) from a table or query.

Limit; bind variables passed to a program unit. Returning a large number of records can impact on performance. This is why we use a subquery such as an inline view. Script Name How to Terminate Loop with FETCH BULK COLLECT LIMIT; Description Many Oracle Database developers are used to executed "EXIT WHEN my_cursor%NOTFOUND" immediately after their fetch inside a loop.
