Question

I have a database with several tables. Each of these tables has a column ‘created’ which contains time-stamps of when that particular row was created in the database.

Now, I want to create a MySQL script that checks once every week if there is data coming into these tables. So, there should be data coming everyday. How do I create a MySQL script that allows me to do this for all the tables in the database?

Note: Remember I want to do this for all the tables in the database with a single script. That’s the main thing I want to know.

i use this approach for a table called call, with a column of timestamp type called systemdate:

SELECT * FROM `call` WHERE DATE(`systemdate`) = DATE(NOW());

mysql DATE() statement gets the datepart of a datetime or timestamp field.

Sorry, just noticed that you want to check if atleast there is an entry for each of the days in the previous week.

you can use this query to check the prevous days individually:

yesterday:

SELECT * FROM `call` WHERE DATE(`systemdate`) = DATE(NOW()) - 1;

before yesterday:

SELECT * FROM `call` WHERE DATE(`systemdate`) = DATE(NOW()) - 2;

Or you can check the whole week at once:

SELECT * FROM `call` WHERE DATE(`systemdate`) > DATE_SUB(CURDATE(), INTERVAL 7 DAY)  GROUP BY DATE(`systemdate`);

This will return one result for each day, so if you have 7 results you’ll know at least an entry was made on each day.
