sql - ケース内の SQL Server 2008 Update

Question

顧客の通話を発信者に割り当てるためのストアド プロシージャを作成しようとしています。変数 @team_id で識別されるコーラーのチームがいくつかあります。私がやりたいことは、顧客 (@code) に誰かが割り当てられているかどうかを確認することです。もしそうなら、その人のIDを返してください。そうでない場合は、割り当て先を決定する THEN ステートメントを実行し、レコードをその発信者に更新して、その発信者の ID を返します。これが私が持っているものですが、選択内で更新を実行できません。可能であれば、毎回テーブルを更新する (ストアド プロシージャの最後に update 句を追加する) ことは避けたいと思います。

最初に更新してから、最初の IF ステートメント内で選択しないでください。同じ条件付きロジックを update ステートメントに適用できます。

編集：ここにコードがあります。ただし、テストされていません....
