sql-server - SQL server Increment dates in a loop? or otherwise?

Question

    select 
            pm.pmnum,
        dateadd(MONTH,pm.frequency,pm.nextdate) as calcNEXTDATE
    from pm

...

Can someone help me increment the results of the above, until lets say calcNEXTDATE = 2014-31-12?

如果这是您要查找的内容，您可以创建一个 while 循环来增加天数并添加到表中。因为你的问题包括循环、日期和增量的标签，所以你可以这样

CREATE TABLE #TestTable1
(
Col DATETIME
);


DECLARE @VarDate Datetime = GETDATE()

WHILE @VarDate <= '2014-12-31 00:00:00.000'
BEGIN
        INSERT INTO #TestTable1(Col)
        VALUES (@VarDate)
  SET @VarDate = DATEADD(DAY, 1, @VarDate)
END
