Question

I have a pretty big table where I want to get certain rows by Id. To save data I need to send a list of Ids, which can be up to a few thousands. I’ve tried the way to send the ids by commaseperated string to a stored procedure, but to convert the string back to a selectable list took a few minutes.
Now I’ve tried with Contains on a view, but I always get an error, that I used too many parameters.

Is there a best practice way to solve my problem? Thanks in advance – hope you know what I mean.

With direct C# and SQL, you can use table value parameters – it’s a way to pass an in memory table to a sproc.

I don’t believe Linq supports it. But, I found this article concerning using TVPs via Linq with a workaround (haven’t tried it):

Hope that helps.
