The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

The same record might exist in both databases.
How do I merge Employee2 into Employee1 but I don't want it merged if the emailaddress is a duplicate?

select * from Employee1
union All
select * from Employee2

save the query as UnionQuery

 create a new table and set the field email with no duplicates
then run this query

insert into NewEmployee
select  UnionQuery.*
from UnionQuery

In the employee1 database, link to the table in Employee2 database.

Do the tables in the two databases have the same table name? If so when you link to it, it will have a 1 added to the table name.

Create a append query, From the Employee2 table into the Employee1 table. Add the Employee2 and Employee1 table into the query, with a join between the two tables on email address. Set the join condition to include all the Employee2 records. Set a where condition on Employee1 table email address to be were is Null.

Once you have the database linked in, the following query will do what you are asking, adjust the tablenames and paste it into SQL view of a new query.

Hope this helps.

So if two different people share the same Email address, which one?

I think I posed the question incorrectly.  I'm sorry.  Here I go again:
I have 2 database files: Employee1 and Employee2.  I want to compare Employee2 to Employee1.  If the record exist in Employee2, then I want it deleted in Employee1.

better if you have a recordid field from both table.

delete *
from employee1,employee2
where employee1.recordID in(select recordid from employee2)

or

delete *
from employee1,employee2
where employee1.EmailAddress in(select EmailAddress from employee2)

or

delete *
from employee1,employee2
where employee1.EmailAddress & employee1.firstname & employee1.lastName in(select EmailAddress & firstname & lastname from employee2)

Accepted Solution
