What does * mean in sql?

I am providing you answer by seperating each part of code.

SELECT == It orders the computer to include or select each content from the database name(table ) .

(*) == means all {till here code means include all from the database.}

FROM == It refers from where we have to select the data.

example_table == This is the name of the database from where we have to select data.

the overall meaning is :

include all data from the databse whose name is example_table.

thanks.
