Before you can read something from the table, you need to put that something there in the first place, right? To create a record in SQL you use
insert into `user` (`name`, `email`, `password`, `registered`) values ('Silvia', 'firstname.lastname@example.org', 'silvia1990', '2019-05-12');
Query OK, 1 row affected (0.06 sec)
We've specified a table name where we're going to insert data into. After that we've enumerated column names which values we're going to insert. And finally, we've put their corresponding data values. Those values should have the same order as column names in the statement before
values keyword. They don't have to match the order of columns in the table. Order of names and values should match within the same
insert statement only.
You can insert multiple records within the same
insert into `user` (`name`, `email`, `password`, `registered`) values ('Angel', 'email@example.com', '1PzIjSWmj3', '2020-02-07'), ('Carolina', 'firstname.lastname@example.org', 'funnybunny95', '2020-06-12'), ('Michael', 'email@example.com', '84738257342', '2020-09-24');
Query OK, 3 rows affected (0.12 sec) Records: 3 Duplicates: 0 Warnings: 0
In real life database you shouldn't keep user's passwords in an unencrypted way. We'll discuss how to do this properly some later.
Alright, the records has been inserted into the table. Now it's time to learn how to read them.
