SQL Server的比較兩個查詢的結果應該是相同的

Question

我稍微修改SQL Server 2005的存儲過程的表現，我想快點確保舊的存儲過程和新的返回完全相同的結果（列是相同的，我想確保行是相同的）。

有一個簡單的辦法在SQL Server 2005中做到這一點？

Answer 1

可以使用除了構建兩個查詢之間的匹配。

select * from (select * from query1) as query1 
except 
select * from (select * from query2) as query2 

編輯：

然後反向查詢，以找到QUERY2作爲驅動差異：

select * from (select * from query2) as query2 
except 
select * from (select * from query1) as query1 

Answer 2

創建兩個臨時表，一個用於每個過程。 運行該過程將行插入適當的表。

然後選擇*從一減SELECT * FROM其他，反之亦然

Answer 3

create table #OldProcResults (
    <Blah> 
) 

create table #NewProcResults (
    <Blih> 
) 

insert into #OldProcResults 
    exec MyOldProc 

insert into #NewProcResults 
    exec MyNewProc 

然後用刺戳的回答這兩個表進行比較。

Answer 4

的存儲過程下面將比較的2個存儲過程，或2條語句的輸出結果集。這裏的關鍵是SP 並不需要知道結果的結構或模式設置，因此，你可以隨意測試任何SP。如果輸出相同，它將返回0行。該解決方案在SQL Server中使用openrowset命令。 這裏是存儲過程

DECLARE @SQL_SP1 VARCHAR(MAX) 
DECLARE @SQL_SP2 VARCHAR(MAX) 

-- Compare results of 2 Stored Procs 
SET @SQL_SP1 = 'EXEC SomeDB.dbo.[usp_GetWithTheProgram_OLD] 100, ''SomeParamX''' 
SET @SQL_SP1 = 'EXEC SomeDB.dbo.[usp_GetWithTheProgram_NEW] 50, ''SomeParamX''' 
EXEC utlCompareStatementResults @SQL_SP1, @SQL_SP2 

-- Compare just 2 SQL Statements 
SET @SQL_SP1 = 'SELECT * FROM SomeDB.dbo.Table1 WHERE CreatedOn > ''2016-05-08''' 
SET @SQL_SP1 = 'SELECT * FROM SomeDB.dbo.Table1 WHERE CreatedOn > ''2016-06-11''' 
EXEC utlCompareStatementResults @SQL_SP1, @SQL_SP2 

的一些示例使用的SP需要以下前提條件，這可能不是理想的生產環境，但對於當地QA，開發和測試的環境是非常有用的。它在代碼中使用openrowset。

EXEC sp_configure 'show advanced options', 1 
EXEC sp_configure 'ad hoc distributed queries', 1 
EXEC sp_serveroption @@SERVERNAME, 'DATA ACCESS', TRUE 

這裏是存儲過程的代碼。

================================================================================== 
    --== SUMMARY utlCompareStatementResults 
    --== - requires sp_configure 'show advanced options', 1 
    --== - requires sp_configure 'ad hoc distributed queries', 1 
    --== - maybe requires EXEC sp_serveroption @@SERVERNAME, 'DATA ACCESS', TRUE 
    --== - requires the RecordSet Output to have Unique ColumnNames (no duplicate columns) 
    --== - requires references in straight SQL to be fully qualified [dbname].[schema].[objects] but not within an SP 
    --== - requires references SP call to be fully qualifed [dbname].[schema].[spname] but not objects with the SP 
    --== OUTPUT 
    --== Differences are returned 
    --== If there is no recordset returned, then theres no differences 
    --== However if you are comparing 2 empty recordsets, it doesn't mean anything
