1 Can you use a batch SQL or store procedure to calculating the Number of Days in a Month?I am trying to find a way to calculate the total number of days in each month.I am trying to avoid using a case statement, as it fails for February on leap years. 理解题意，也想到了使用DateDiff这样的日期处理函数。 但是由于传入的参数是整数而非日期类型，当传入参数错误时缺乏对异常的捕获和控制处理。 例如： exec sp_DayOfthisMonth 2006, 13 exec sp_DayOfthisMonth 2006, -1 将会发生数据类型转换错误。 并且由于在计算下一月份时没有使用DateAdd函数，而是简单的让@month加1， 当传入月份参数为12时将会出错，也即该存<img src ="aggbug/1634122.aspx" width = "1" height = "1" />Fri, 01 Jun 2007 21:40:00
