Question

image this two tables:

Table: Item Columns: ItemID, Title  Table: Tag Columns: TagID, ItemID, Title 

Which is the best way (without changing table structure (yes, I don’t mind if they are not normalized)) to retrieve a list of items with all their tags attached using less possible query (i.e. not doing 11 queries to retrieve 10 items)?

Answer 1

Here’s a simple outer join. Is that what you are after?

SELECT   It.ItemID,   It.Title [ItemTitle],   Tg.TagID,   Tg.Title [TagTitle] FROM Item It LEFT OUTER JOIN Tag Tg ON It.ItemID = Tg.ItemID
