常用函数的使用

/*cast()类型转换函数*/
/*datepart()取部分日期函数*/
/*getdate()取当前服务器日期*/
example:
select cast(datepart(year,getdate()) as varchar)+'年' as year,cast(datepart(month,getdate()) as varchar)+'月' as month,cast(datepart(day,getdate()) as varchar)+'日' as day

/*查看当前服务器版本 */
print @@version
select serverproperty('productversion'),serverproperty('productlevel'),serverproperty('edition')
select serverproperty('EngineEdition')
