How do I bring back all records by date where one date has a certain value?

Question

0.00/5 (No votes)

See more:

I have a table containing Dates and a foreign key linking the date to a type.

The majority of Dates are of type 1 but every now and then one will be a type 2.

I would like an SQL query to return all records from a date if one of them is of type 2.

I am having a mental block right now so i'm posting here to see if anyone can help me out whilst i'm stuck thinking, if not i will update with an answer as soon as i manage to get it.

What I have tried:

I tried making a list of dates that match type 2 then a query to return all records for each date in the list. I'm just having trouble getting them into one DataTable, and i am sure there is a much better one query way to do it anyway.

Build the query in SQL Server, move it to a stored procedure (or build a view), and call it from your code. It will be MUCH easier that way.

Beyond that, we can't really help you without the relevant part of your table schemas and a description how the datetime is used to determine the record's type.
