You're looking at it backwards. You're not excluding rows that meet certain conditions, you're SELECTING rows that meet certain conditions. That's why the command is called SELECT.

"I want to select unique records from same Name ___if "CanAccess" is true___ for any of them."

Does this not conflict with your sample Output where
Inventory ===== 0
Finance ===== 0

?

No. It's does not conflict with my solution. Based on the sample data you provided, aggregation is not necessary. A simple select statement will suffice. Of course, there may be something you're not telling us, but we can't just divine that by praying to a large rock in the back yard to seek guidance.

Solution 1

SQL

select name from [mytablenmame] where CanAccess=1

[EDIT]
Given the OP's sample data, where there are only TWO records for a given name, and EACH of them having a different value for CanAccess, aggregation is not required to get the results he claims to be after. Stop 1-voting my answer.

No mate, please see the updated question.

How does my solution not give him the results he wants. Without seeing his data and understanding WHY he has two records for the same name with different values for CanAccess, we cannot POSSIBLY give him the query he needs. Based on his illustrated data, and the text of his question, there is no need for anything in the query that would demand a clause that would establish "unique" records. Voting my answer a 1 was uncalled for.
