Hi all, Let's say I have the canonical employee table. Let's say I have a dept_id field. Let's say that there are 1000+ employees in each department. Can it be done via sql that I need to see, say 10 employees from each department? select emp_last_name, dept_id from employee (but only fetch 10 employees for each department and I do want all departments selected). Hope that makes sense. TIA, Sashi |

Hope that makes sense. TIA, Sashi Yes, it is possible. *Take a look at the following example:http://hoopercharles.wordpress.com/2...ing-generating... If you read through that example, take a close look at what is shown for the output of the first SELECT SQL statement. *If you were to slide that SQL statement into an inline view, you could then add a WHERE clause like this to retrieve the first 10 employees sorted by name from each of the departments: * WHERE * * RN <= 10 Charles Hooper Co-author of "Expert Oracle Practices: Oracle Database Administration from the Oak Table"http://hoopercharles.wordpress.com/ IT Manager/Oracle DBA K&M Machine-Fabricating, Inc. |
