Hi all,
I am checking Row-Chaining in one of Production
Environment. But at the end I am not able to reconcile
my results. I would appreciate if someone help me doing
that......
After analyzing one table I see that it has 4202 Chained Rows.
Then I run following SQL
SQL> select value
2 from v$sysstat
3 where name = 'table fetch continued row';
VALUE
----------
951
SQL> Select my.value
2 From v$mystat my,
3 V$sysstat sys
4 Where my.statistic# = sys.statistic#
5 And sys.name = 'table fetch continued row';
VALUE
----------
0
Now I do
SQL> select * from prasanta.tdpsv ;
After this I run following queries again,
SQL> Select my.value
2 From v$mystat my,
3 V$sysstat sys
4 Where my.statistic# = sys.statistic#
5 And sys.name = 'table fetch continued row'
VALUE
----------
0
SQL> select value
2 from v$sysstat
3 where name = 'table fetch continued row'
VALUE
----------
960
Shouldn't the above two values be 4202 and 5153, as per
description of 'table fetch continued row' ?? Am I
missing something????
TIA,
Rajesh
