Hi,
I understand that when a table contains only a few rows it is better to
do a sequence scan than an index scan. But is this also for a table with
99 records?
A table contains
id integer (primary key)
name varchar(70)
parent integer
comment text
owner integer
inheritAccess integer
defaultAccess integer
sequence bigint
contentsinheritaccessmove integer
contentsinheritaccessadd integer
explain select * from tblFolders where id=90;
QUERY PLAN
-----------------------------------------------------------
Seq Scan on tblfolders (cost=0.00..3.24 rows=1 width=50)
Filter: (id = 90)
(I have analyze table bit still a sequence scan).
With how manys rows it is ok to do an index scan or sequence scan? How
is this calculated in pg?
Regards
Jer
