查詢當天數據

select    now() ->yyyy-MM-dd hh:mm:ss   當下年月日時分秒
select    CURRENT_DATE                  當下年月日

如果查詢出數據字段爲null的話,我們爲它賦值一個數字,這樣的話在程序中也不用再去做判斷了

	SELECT IFNULL('字段',0)   
    如果查詢出該字段在數據庫中爲null,則我們爲它賦值爲0

縱轉橫

註釋：例如,我在查詢時對某個(班級)字段進行分組了,那麼這個班級是不是有多個學生？那麼我怎麼將這幾個學生統統歸在一行呢？

例如我要展示的是這樣的

班級(class) 學生(students)

1年級李四,張三,李廣

2年級李明,思思

SQL寫法如下：

//GROUP_CONCAT -函數作用就是將學生字段縱轉橫  以逗號往後疊加
//如果是計算總成績 就是  sum（student）~~~~
select class,GROUP_CONCAT(ts.student SEPARATOR ',') as 'students' from table_name group by class
