如何从mysql databse php获取单个记录的时间戳？

Question

Currently working with database and my client was confused with the db.

I have a table with three columns named

'fname' | 'lname' | 'email'

• now i have inserted 50 records on 8 april
• i have inserted 30 records and updated 10 record of 8 april on 9 april
• i have inserted 20 records on 10 april

Now i want to fetch the records that were inserted or updated on particular date.

for example: i need a query such that i can fetch the records i play with on 9 april.(ie 30 inserted records and 10 updated records.). So i can fetch the 40 rows.

I'm not sure how to do this.

Answer 1

Impossible to do. You need two more columns with a datetime type to store the created date and the updated date

Answer 2

您需要在表中添加诸如create_dt之类的列，该列将在表中插入新行时存储当前日期
