openquery passing dateパラメータの変換に失敗しました。

Question

SSRS内でデータセットを作成するために、次のストアドプロシージャを作成しました。しかし、SSRSでクエリを実行すると、文字列から日付を変換するときに変換エラーが発生します。私はそれが構文か可変の問題であると確信しています。何か案は？

ALTER PROCEDURE [dbo].[usp_r_pcdh_counts] 
    @START datetime, 
    @END datetime 
     AS 
     BEGIN 
     SET NOCOUNT ON; 
    DECLARE @START1 datetime= @START 
    DECLARE @END1 datetime = @END 
    DECLARE @sql nvarchar (4000) 
    SET @sql= 'SELECT * 
    FROM OPENQUERY(MR_UNI,''select 
       count(case when event_audit_type_key in ("1346","1038") then 1 else null end) as outsuccessful, 
       count(case when event_audit_type_key = "1531" then 1 else null end) as outunsuccessful, 
       count(case when event_audit_type_key in ("1040") then 1 else null end) as outdocsfound, 
       count(case when event_audit_type_key in ("1532") then 1 else null end) as outdocsnotfound, 
       count(case when event_audit_type_key in ("1042") then 1 else null end) as outdocsretrieved, 
       count(case when event_audit_type_key in ("1580") then 1 else null end) as outdocsnotretrieved, 
       count(case when event_audit_type_key in ("1048") then 1 else null end) as insuccess, 
       count(case when event_audit_type_key in ("1048") and success_code = "12" then 1 else null end) as infailure, 
       count(case when event_audit_type_key in ("1050") then 1 else null end) as indocsretrieved 
      from public.event_audit ea 
      where ea.event_date >= convert(date,''''' + @START1+ ''''', 110) 
        and ea.event_date < convert(date, '''''+ @END1+ ''''', 110) 
        AND event_audit_key >= (SELECT MAX(event_audit_key) - 100 
         FROM reports.event_audit_index 
         WHERE event_date <= convert(date, '''''+ @START1+ ''''', 110)) 
        AND event_audit_key <= (SELECT MIN(event_audit_key) + 100 
         FROM reports.event_audit_index 
          WHERE event_date >= convert(date, '''''+ @END1+''''', 110))'')' 
    EXEC @sql 
    END

動的SQL（DSQL）をダブルネストしていますが、これはバットの痛みです。トリックはになります。ダイナミックロジックのレイヤーに簡単なprintステートメントを付けて、そのレベルの構文をチェックします。これにより、この種の問題のトラブルシューティングに役立ちます。

かかわらず、これはあなたが探している与えるべきである：

ALTER PROCEDURE [dbo].[usp_r_pcdh_counts]

    @END datetime 
    AS 
    BEGIN 
    SET NOCOUNT ON;

DECLARE @END1 datetime = @END 
DECLARE @sql nvarchar (4000) 
SET @sql= 'SELECT * 
FROM OPENQUERY(MR_UNI,''select 
      count(case when event_audit_type_key in (1346,1038) then 1 else null end) as outsuccessful, 
      count(case when event_audit_type_key = 1531 then 1 else null end) as outunsuccessful,

--PRINT @sql 
EXEC @sql 
END
