I'm having issues getting the following query to work.
"SELECT * FROM Recipe WHERE Recipe.RecipeID EXISTS (SELECT * FROM RecpCat WHERE RecpCat.RecpCatID = " & catID & ")"
catID is being passed in as a parameter (it's an ASP page).
The database structure looks like this:
Table: Recipe
RecipeID (INT)
...
Table: RecpCat
RecipeID (INT)
RecpCatID (INT)
The RecpCat table implements a many-to-many relationship for the recipes (a recipe can be in multiple categories).
The error I'm getting is:
Incorrect syntax near the keyword 'EXISTS'.
If there's a better way to do this, please let me know; I'm not proud... 🙂
Thanks,
Brandon

How about (I'm using @catID to represent the parameter... here's the basic SQL query):
SELECT
R.*
FROM Recipe R
JOIN RecpCat RC
ON R.RecipeID = RC.RecipeID
WHERE
RC.RecpCatID = @catID

Actually, I figured out why I was getting an error. I was doing a SELECT * instead of only returning one column from the subquery.
I changed the SQL statement to read like below and it works perfectly.
"SELECT * FROM Recipe WHERE Recipe.RecipeID EXISTS (SELECT RecipeID FROM RecpCat WHERE RecpCat.RecpCatID = " & catID & ")"
