How to write stored procedures to accept a collection to delete rows using IN operation? [duplicate]

Answer 1

One method is to use a Table type parameter, and a JOIN. Assuming ENTRY_ID is an int:

CREATE TYPE dbo.EntryList AS TABLE (Entry_ID int NOT NULL);
GO

CREATE PROC dbo.DeleteListEntry @Entries dbo.EntryList READONLY AS
BEGIN

    DELETE LI
    FROM LIST_ITEMS LI
         JOIN @Entries E ON LI.ENTRY_ID = E.Entry_ID ;
END;

Then you can call the SP by doing:

DECLARE @Entries dbo.EntryList;
INSERT INTO @Entries
VALUES(1),(2),(3);

EXEC dbo.DeleteListEntry @Entries;
