Use sql override

Query goes like this, If I Take Table name as AS EMP, then....

SELECT * FROM  EMP

WHERE ROWNUM<=(SELECT COUNT(*) FROM EMP) MINUS

SELECT * FROM EMP WHERE ROWNUM<=(SELECT COUNT(*)-n FROM EMP);

N=NUMBER IN EMP TABLE WE HAVE 14 TABLES IF U GIVE N AS 3 THEN IT WILL GIVE U LAST 3 ROWS. OK

hi,connect a sequence generator next to source qualifier into the expression.Use the filter trans to filter rows like where nextval>500.

We can go with sequence generator but if u want to increase the session performance go for SQL Override

Hi,

If the source is flatfile we can't use sql override. 

Better go for sequence generator,conn.. the s.g o/p to expression trns..

inside the expr.. trns.. we can write condition like 

sequence no.>=500 and sequence no.<=1000.

sequence no. are what you are getting from s.g.

You should set sequence trns.. in reset mode, then only you can get same no. for every exec..

hi  the above condition holds good in case of static loading,

say, I have 10000 recs in my source to load, but while loading it fails say at 6887th record,

how can i reload just the remaining record 3313 records alone :-)

thanks in advance. infoseeker

u can load 500 records, then we can use Transaction control transformation, give the condition for 500 records out of 1000.

SELECT *
FROM (select * from source_table ORDER BY rownum DESC) Source
WHERE rownum <= 501
