Get block_size for a datafile

admin — Fri, 01 May 2009 11:06:54 +0000

You may need to get the block size of a datafile before running dbv (DBVERIFY) on it. The following will do this in sqlplus:

set wrap off
select t.name tablespace, file#, d.name datafile, block_size BS from v$datafile d join v$tablespace t using (ts#);

Equivalent of mysql limit clase for sqlplus

admin — Tue, 18 Nov 2008 03:13:31 +0000

SELECT a, b, c
FROM
( SELECT a, b, c, ROWNUM rn
  FROM
  ( SELECT a, b, c FROM RECORD
    WHERE AVAIL='Y"
    ORDER BY DATE DESC
  )
  WHERE ROWNUM <= 25
)
WHERE rn >= 21;

This clunky code is the equivalent of mysql's elegant:
select a,b,c from record limit 5 offset 4;
