光标内存储过程中的DateTime转换错误

Question

当我尝试将日期时间字符串（yyyy-MM-dd HH：mm TT）转换为Cursor内存储过程中的SQL DateTime时，我面临如下错误。

  

从字符串转换日期和/或时间时转换失败。

我在下面粘贴了我的商店程序，并在INSERT语句中的第131行错误抛出，转换了2个变量@var1＆amp; @var2到DATETIME。

SQL Server版本：

测试变量值：

@Log = "8/6/2015 1:37:00 PM"
@stBreakTimeStart = "1:00 PM"
@stBreakTimeEnd = "2:00 PM"

近似@var1＆amp; @var2测试值：

@var1 = "2015-08-06 1:00 PM"
@var2 = "2015-08-06 2:00 PM"

我的商店程序：
