Question

I have a list of record Id’s that I want to retrieve from Sql Server. I’m trying to figure out what the most performant way doing this would be. For example in code I have this:

var recordsToFind = new List<long>{ 12345, 12346, 45756, 42423 ... }

I want to create a stored proc that does this:

Select * From Puzzles where ID = {any of the integers passed in}

I know there are several options like, table value parameters, converting the list into a comma seperated string and using CharIndex, created a temp table and splitting the string etc…

What would be the best approach keeping in mind this will be used A LOT!

Thanks!

Several must read articles about this can be found here: http://www.sommarskog.se/arrays-in-sql.html Performance considerations are addressed in those articles.
