如果包含转换为Char（10）的日期时间，则T-SQL Raiserror会丢失消息

declare @TmsString  char(10),
        @TmsLast    datetime,
        @UserMsg    varchar(500)

select @TmsLast = getdate()

select  @TmsString = ltrim(rtrim(convert(char(10), @TmsLast, 101)))
select  @UserMsg = '*' + ltrim(rtrim(cast(@TmsString as char))) + '*'

raiserror (@UserMsg, 12, 1)
return
