如何在SQL中的两个单独的表上打印奇数和偶数？

Question

我的SQL代码中已经有了这么多。我很难根据奇数和偶数将我的数据打印在两个单独的表中。提前感谢您的意见。我真的很感激。

DECLARE
  @empNM CHAR(15),
  @empID INT,
  @reportsTO INT
DECLARE
  emp CURSOR dynamic FOR 
SELECT Employee_NM, Employee_ID, ReportsTo
    FROM employeetable
    ORDER BY Employee_ID ASC
OPEN emp
FETCH NEXT
  FROM emp
  INTO @empNM, @empID, @reportsTO;
PRINT 'name           id          boss'

WHILE (@@fetch_status <> -1)
IF (@empID % 2 = 0)
BEGIN
  SET @empNM = CONVERT(CHAR,CAST(@empNM AS VARCHAR),1)
  PRINT CAST(@empNM AS VARCHAR)+CAST(@empID AS VARCHAR)+SPACE(11)+CAST(@reportsTO AS varCHAR)


  FETCH NEXT
    FROM emp
    INTO @empNM, @empID, @reportsTO;
END;
ELSE 

BEGIN
 SET @empNM = CONVERT(CHAR,CAST(@empNM AS VARCHAR),1)
  PRINT CAST(@empNM AS VARCHAR)+CAST(@empID AS VARCHAR)+SPACE(11)+CAST(@reportsTO AS varCHAR)
  FETCH NEXT
    FROM emp
    INTO @empNM, @empID, @reportsTO;
END;
CLOSE emp;
DEALLOCATE emp;

这是理想的结果......

您没有使用C＃循环数据。使用SQL，您必须处理整个数据集，因此没有游标。 （在大多数情况下）

您必须为每个表执行1次插入：

Insert Into TOdd(Name, Id, Boss) Select Name, Id, Boss From T Where id % 2 = 1
Insert Into TEven(Name, Id, Boss) Select Name, Id, Boss From T Where id % 2 = 0
