SQL to return records in m,n sequence

I want my SQL to return only records from 101 to 200. See below options which would do the required.. Select * from (Select rownum rownumber,employee.* from employee) Where rownumber between 101 and 200; -- Using rownum label in oracle Select * from (Select employee.*, row_number() over (order by emp_id desc) Rownumber from employee) where Rownumber between 101 and 200; --Using the analytical function row_number Select * from (Select employee.*, row_number() over (order by emp_id desc) Rownumber from employee) where Rownumber between :Fromnumber and :tonumber; -- lets user decide the recordset chunk... Hope this is helpful!!!!!!

This is where you declare Variables that you are going to use it in PLSQL block ............ Data types are chosen based on requirement.

What happens when you create tables with the existing SYNONYM names

See below snippets: Select * from dba_synonyms where synonym_name='DUAL'; OWNER SYNONYM_NAME TABLE_OWNER TABLE_NAME DB_LINK PUBLIC DUAL SYS DUAL (NULL) We know that DUAL table is accessible by users. Lets create a table named DUAL under our schema (USER). CREATE TABLE dual AS SELECT * FROM dual; Select * from dual; insert into dual values('Y'); commit; Select * from dual; DUMMY ---------- X Y The Synonym is not referred unless the Synonym name is not used by any object under the USER/SCHEMA... So , When creating tables in your schema, take a look at SYNONYMs declared as PUBLIC and try not to use them.
