This seems like a pretty straight forward query. Can you show us what you've tried and where you are stuck?

As John said above, this looks pretty straight-forward

I will give you some hints to get you started though

1. Have a look at INNER JOIN's and LEFT OUTER JOIN's in BOL or Google and use one of these in the below steps as required

2. Perform a JOIN between Log Table and employee table to get FullName of From User ID

3. Perform another JOIN between the same set of tables to get FullName of To User ID

4. Perform a JOIN between Log Table and Materials to get the Serial #

Let us know if you have any troubles in following the steps and we will be glad to help.

select * from (select * from log_table where from_user_id in (select userid from employee_table)

union

select * from log_table where to_user_id in (select userid from employee_table)) a where logid in (select logid from materials_table)

Bala,

user wants to produce the results of below fields

FullName of From User ID | Full Name of To User ID| Serail # |date |

your query will not produce proper results.
