select ステートメント ( 5000 レコード) を作成するストアド プロシージャがあります。select ステートメント内で、テーブル値関数を呼び出します。テーブル値関数は、いくつかの集計計算を実行します
結果を返すのに 1 分以上かかる
ここに集計関数コードがあります
ALTER FUNCTION [dbo].[GetParticipationEvaluation](@Participation_ID int)
RETURNS @TabEvaluation TABLE (
JudgeCount int NOT NULL,
JudgeEvaluationCount int NOT NULL,
Evaluation float
)
AS
BEGIN
declare @JudgeCount int
declare @JudgeEvaluationCount int
declare @Evaluation float
SELECT
@JudgeCount=COUNT(*),@Evaluation= AVG(Evaluation) from Judge_Participation where Participation_ID=@Participation_ID and Sys_Is_Active=1
and status_ID =2
SELECT
@JudgeEvaluationCount=COUNT(*),@Evaluation= AVG(Evaluation) from Judge_Participation where Participation_ID=@Participation_ID and Sys_Is_Active=1
INSERT INTO @TabEvaluation (JudgeCount, JudgeEvaluationCount, Evaluation)
select @JudgeCount,@JudgeEvaluationCount,@Evaluation
RETURN;
END;
