hi
I would like to know how many rows will fit into a data block of size 4k. Given that there are 5 columns in a table. The datatypes are
number
varchar(50)
varchar(500)
date
char(10)
There are initially 20000 rows and increasing at the rete of 20000 rows per day.
Assume that this is the only table in the tablespace.
bye

Easiest way is to get the free copy of TOAD from

http://www.toadsoft.com

Go to 'tuning/estimate table size' and use enter the no of records you are expecting.

Good luck.

NUMBER, DATE, and CHAR are static but VARCHAR2 isn't. Your best bet is to analyze the table with COMPUTE and look at AVG_ROW_LEN in DBA_TABLES for that table.
