SQL Server存儲過程錯誤。無效標識符

Question

我有一個存儲過程，但是當我從我的前端執行它，我得到這個錯誤：

The name 'CREATE TABLE tmp_148_58 (affili_item_id varchar(250),academic_id varchar(250),college_id varchar(250),item_value_quantity_college_entry varchar(250),item_value_notes_college_entry varchar(250),college_enter_on varchar(250),college_enter_by varchar(250),affili_category_colleges_autoid varchar(20))' is not a valid identifier.

我的程序代碼：

ALTER PROCEDURE [dbo].[SpPortal_AppForAffi_Upd_Both_Lbl_And_Vals1] 
    (@columnList TEXT 
    ,@insScript nvarchar(1000) 
    ,@collegeId INT 
    ,@LoginId BIGINT)

     @effectCount INT = 0, 
     @effectCountTotal INT = 0, 
     @ExeQuery nvarchar(1000), 
     @InsertQuery nvarchar(1000) 

    SET @tmpTableName = CONCAT('#tmp_',@collegeId,'_',@LoginId); 

    SET @ExeQuery = CONCAT('DROP TABLE IF EXISTS ', @tmpTableName);    

    EXECUTE @ExeQuery ; 

    -- create temp table.. --

    EXECUTE @ExeQuery;  

    declare @te int=0 

    SET @ExeQuery = CONCAT ('SELECT COUNT(tem.affili_item_id) INTO @te 
    FROM ',@tmpTableName,' tem INNER JOIN affili_items afi ON tem.affili_item_id = afi.affili_item_id AND afi.is_label <> 1 
    WHERE afi.active_status = 1 ') ; 

    EXECUTE @ExeQuery; 

    SET @effectCount=0; 
    SET @effectCount = @te ; 

     IF(@effectCount>0) 
     BEGIN 

     SET @effectCountTotal= @effectCount+1; 

     END 

    -- SET param_sp_success = effectCountTotal; 
IF(@@TRANCOUNT>0) 
     BEGIN 
      COMMIT TRANSACTION 
     END 
    ELSE 
     BEGIN 
      ROLLBACK TRANSACTION 
     END 
    END TRY 

    BEGIN CATCH 
     ROLLBACK TRANSACTION 
    END CATCH 

END 

誰能幫我解決它？我將上面的查詢從mysql轉換爲SQL Server。

Answer 1

首先 - 我真的不知道爲什麼你使用這一切動態創建的報表。正如我從腳本中看到的 - 唯一的原因是您創建臨時表的唯一名稱。

但是，您並不需要臨時表具有唯一的名稱，因爲此表僅在存儲過程的創建範圍內可見（並且也位於從該存儲過程調用的「子」過程的範圍內）。

此外，根據您的錯誤，它看起來像您的腳本試圖創建真實的，而不是臨時表 - 請參閱CREATE TABLE tmp_148_58 - 表的名稱不包含#。因此，您可能無權在運行sp的帳戶下創建真實的表格。

我建議你重寫你的代碼沒有這種混亂的動態和錯誤應該消失;）
