SELECT columns FROM table OFFSET start_row ROWS FETCH FIRST num_rows ROWS ONLY

SELECT columns FROM table ROWS start_row TO end_row

All versions

SELECT FIRST num_rows SKIP start_row columns FROM table

• SELECT FIRST num_rows columns FROM table
• SELECT columns FROM table OFFSET start_row FETCH {FIRST|NEXT} num_rows ROWS ONLY

SELECT columns FROM table FETCH FIRST num_rows
SELECT columns FROM table LIMIT start_row, num_rows
(rows are numbered from 0)

• SELECT columns FROM table OFFSET start_row ROWS FETCH { FIRST | NEXT } num_rows ROW[S] ONLY
• Simple version (when start_row = 0):

SELECT TOP num_rows columns FROM table

SELECT columns FROM table LIMIT num_rows OFFSET start_row

All versions

SELECT columns FROM table LIMIT start_row, num_rows

-- Notice: Will not work, if start_row > 1, since the first row will return false, and the cursor will terminate.
SELECT columns FROM table WHERE rownum >= start_row AND rownum <= end_row

This works fine without specifying start_row:

SELECT columns FROM table WHERE rownum <= end_row

This also works, but suffix num column in resultset:

SELECT * FROM (
  SELECT temp.*, rownum num FROM table ORDER BY columns
  ) WHERE num >= start_row and num <= end_row

Since 12.1, similar to standards:

SELECT columns FROM table FETCH FIRST num_rows ROWS ONLY
SELECT columns FROM table OFFSET start_row ROWS FETCH FIRST num_rows ROWS ONLY

Full syntax: (Can have OFFSET, or FETCH, or both clauses)

SELECT column [, column2 …] FROM table [ORDER BY column2] 
[OFFSET start_row ROWS] 
[FETCH [FIRST|NEXT] [num_rows|percent PERCENT] ROWS [ONLY|WITH TIES]]

or: The SQL standard syntax.

SELECT TOP num_rows columns FROM table
SELECT TOP skip_rows,num_rows columns FROM table
