このエラーが発生する理由がわかりません。他の誰かがエラーを見つけるのを手伝ってくれますか? 一時テーブルにマージしようとしていますが、エラーが発生します

整数として入力された推測に基づいてProviderBibDateAdded、日時をそれに詰め込もうとしています。更新ステートメントを次のように変更してみてください。

UPDATE
    SET ProviderCustNum      = pt.ProviderCustNum,
        ProviderDivID        = pt.ProviderDivID,
        ProviderBibDateAdded = Cast(pt.ProviderBibDateAdded as Integer),
        ProviderQtyOwned     = pt.ProviderQtyOwned

これへの挿入ステートメント：

INSERT (KTSID, FLRID, SiteShelfID, SiteCustNum, SiteDivID, 
        SiteBibDateAdded, SiteQtyOwned, ProviderShelfID, 
        ProviderCustNum, ProviderDivID, ProviderBibDateAdded, 
        ProviderQtyOwned)
VALUES (pt.KTSID, pt.FLRID, pt.SiteShelfID, pt.SiteCustNum, 
        pt.SiteDivID, NULL, NULL, pt.ProviderShelfID, 
        pt.ProviderCustNum, pt.ProviderDivID, 
        cast(pt.ProviderBibDateAdded as Integer), 
        pt.ProviderQtyOwned)

これが実際に問題である場合は、何かを挿入する前に、明示的なデータ型を使用して一時テーブルを作成することをお勧めします。

Declare @TitleData (
     KTSID integer not null,
     FLRID integer not null,
     SiteShelfID integer not null,
     SiteCustNum varChar(??),
     SiteDivID integer not null,
     SiteBibDateAdded Datetime not null,
     SiteQtyOwned smallInt,
     ProviderShelfID integer not null,
     ProviderCustNum varChar(??) Null,
     ProviderDivID Integer null,
     ProviderBibDateAdded Datetime null,
     ProviderQtyOwned null)

Insert @TitleData (KTSID, FLRID, SiteShelfID, 
    SiteCustNum, SiteDivID, SiteBibDateAdded,
    SiteQtyOwned, ProviderShelfID)
SELECT BookID, ResourceID, ls.ID,
   ls.CustomerNumber, ls.DivisionID,
   st.DateCreated, st.TotalCopies,
   ls.ParentLibraryShelfID
From dapadmin.ShelfTitle st
    JOIN dapadmin.LibraryShelf ls 
       ON st.LibraryShelfID = ls.ID
    JOIN #TitlesToInclude tti     
       ON st.ID = tti.ShelfTitleId
