SQL Server 2005 では、テーブルにプロパティを設定せずにカスケード削除を実行できますか?

あなたのアドバイスとオンラインで見つけたスクリプトを組み合わせて、 ON DELETE CASCADE に関係なくカスケード削除を実行するために実行できる SQL を生成する手順を作成しました .かなりの時間の無駄だったかもしれませんが、書いてよかったです。この方法の利点は、 GO を配置できることです。 各行間のステートメントであり、1 つの大きなトランザクションである必要はありません。元の手順は再帰的な手順でした。これは再帰をスタック テーブルに展開します。

create procedure usp_delete_cascade (
    @base_table_name varchar(200), @base_criteria nvarchar(1000)
)
as begin
    -- Adapted from http://www.sqlteam.com/article/performing-a-cascade-delete-in-sql-server-7
    -- Expects the name of a table, and a conditional for selecting rows
    -- within that table that you want deleted.
    -- Produces SQL that, when run, deletes all table rows referencing the ones
    -- you initially selected, cascading into any number of tables,
    -- without the need for "ON DELETE CASCADE".
    -- Does not appear to work with self-referencing tables, but it will
    -- delete everything beneath them.
    -- To make it easy on the server, put a "GO" statement between each line.
