Help in wriring an sql

Question

Hi gurus,
just wondering whether this sql works fine.
Insert into contact_history@demo (narrative) select substrb(narrative,1,4000) from CONTACT_HISTORY
where I in (select i from missing_ivalue)
where demo is a dblink for source and the target database and narrative is a column name which is varchar2(4000)
contact_history@demo is a target table.
i actually need to insert complete record which has missing i value with the substrb(narrative,1,4000)
any suggestion is highly apprciated
Thanks

toccontact_history@demo is a target table.As per your post,the above insert statement will absolutely work fine,unless if you have insert permission for toccontact_history table,to your present schema,where you are executing the insert statement.Also you need to have db link created to access the tables,created in other schema.
Check the db_link created by using the query
select * from user_db_linksIts always suggested to post a sample data to understand your requirement cleary and we can try to provide you a solution to your problem.
Hope this helps.
