(1) Always use backticks ````` for column names ONLY

(2) Create tables:

create table [tableName](
`column 1` int ,
`column 2` double,
...

primary key(`column 1`)
);

(3) Show columns from tables

show COLUMNS from table;
OR
show columns from table from database;

(4) insert data into tables

insert into tableName(
`column 1`,
`column 2`,
...)
values
(
"value for column 1",
"value for column 2",
...
);

(5) delete rows from table (example)

delete from tableName
where id = 1;
