14. Using each of the tables created for the PRESCHOOL database:
Create SQL function for table attribute (Create Function)?
Create a table corresponding to the topic and create a trigger function to control the updating of data in it?

3 < subquery
If subquery returns count that is less than 3 then select query will return some result.
If subquery returns count that is greater than or equal to three than select query result will be blank

Little example: SELECT FROM cale WHERE from <= ‘yyyy-mm-dd’ AND end >= ‘yyyy-mm-dd’ AND DAY(from) <= DAY(‘yyyy-mm-dd’) AND DAY(to) >= DAY(‘yyyy-mm-dd’);
Abbici 2022-05-28 00:04:05
SELECT FROM cale WHERE from <= ‘yyyy-mm-dd’ AND end >= ‘yyyy-mm-dd’ AND MONTH(from + month*fre) <= MONTH(‘yyyy-mm-dd’) AND MONTH(to + month*fre) >= MONTH(‘yyyy-mm-dd’);

Good afternoon.I am a newbie of MySql. Two hours ago while I was testing my database I got a problem and I cannot find the reason.I create a table and added some rows in that table. I want to delete one of them which have been written in the table and I got an error message but when I try to delete the row that not recorded the DBMS didn’t show me any error message. I have tried to find out at google but I got nothing.Could anybody tell me the reason ? My English is poor , sorry for that.
