％SQL Server中的Rowtype等效項目

Question

我即將將存儲過程從pl/sql轉換爲SQL Server。該過程使用遊標循環查詢select的結果。是否存在與ORACLE rowtype構造相同的SQL Server？

Answer 1

使用遊標的SQL方法如下所示

DECLARE @colA varchar(50), @colB varchar(50) 

DECLARE myCursor CURSOR FOR 
Select columnA, columnB From table 

OPEN myCursor 

FETCH NEXT FROM myCursor INTO @colA, @colB 

WHILE @@FETCH_STATUS = 0 
BEGIN 

--do something with @colA and @colB 

FETCH NEXT FROM myCursor INTO @colA, @colB 

END 

CLOSE myCursor 
DEALLOCATE myCursor

Answer 2

這是一個巨大的原因相比，甲骨文的時候不喜歡的SQL Server。

我很失望SS沒有％TYPE和％ROWTYPE。這樣可以在最初編寫代碼時節省數小時的工作時間，並且在列的類型需要更改的情況下，無需返回並重新處理所有代碼。

在Oracle我以前寫的東西，如：

DECLARE @MyRowVar AS ATable％ROWTYPE;

在SQL Server中，我不得不寫這本：

DECLARE @External_ID    AS BIGINT = NULL; 
DECLARE @PlatformID     AS INT = NULL; 
DECLARE @ActorIDOfReseller   AS INT = NULL; 
DECLARE @ActorIDOfClient   AS INT = NULL; 
DECLARE @ActorIDOfExtension   AS INT = NULL; 
DECLARE @CallType     AS NCHAR (10) = NULL; 
DECLARE @CallInitiatedDate   AS DATE = NULL; 
DECLARE @CallInitiatedTimeHH24MI AS TIME (0) = NULL; 
DECLARE @TimePeriodID    AS INT = NULL; 
DECLARE @CallAnswered    AS DATETIME = NULL; 
DECLARE @CallAnsweredYN    AS BIT = NULL; 
DECLARE @CallDispositionID   AS INT = NULL; 
DECLARE @CountryID     AS INT = NULL; 
DECLARE @CallPrefixID    AS INT = NULL; 
DECLARE @FromNumber     AS VARCHAR (32) = NULL; 
DECLARE @ToNumber     AS VARCHAR (80) = NULL; 
DECLARE @CallDuration    AS INT = NULL; 
DECLARE @CallCostToExtension  AS DECIMAL (10, 6) = NULL; 
DECLARE @CallCostToClient   AS DECIMAL (10, 6) = NULL; 
DECLARE @CallCostToReseller   AS DECIMAL (10, 6) = NULL; 
DECLARE @CallCostToAdmin   AS DECIMAL (10, 6) = NULL; 
DECLARE @Flow      AS VARCHAR (3) = NULL; 
DECLARE @CallStart     AS DATETIME = NULL; 
DECLARE @MoneyUnit     AS VARCHAR (32) = NULL; 
DECLARE @Prefix      AS VARCHAR (32) = NULL; 
DECLARE @External_CallID   AS VARCHAR (255) = NULL; 

這讓我很傷心。
