11. Video: SELECT & FROM
SELECT & FROM Statements
Here you were introduced to the SQL command that will be used in every query you write: SELECT … FROM ….
- SELECT indicates which column(s) you want to be given the data for.
- FROM specifies from which table(s) you want to select the columns. Notice the columns need to exist in this table.
If you want to be provided with the data from all columns in the table, you use "*", like so:
- SELECT * FROM orders
Note that using SELECT does not create a new table with these columns in the database, it just provides the data to you as the results, or output, of this command.
You will use this SQL SELECT statement in every query in this course, but you will be learning a few additional statements and operators that can be used along with them to ask more advanced questions of your data.
