Join Bill Weinman for an in-depth discussion in this video Selecting rows, part of MySQL Essential Training (2014).
…The Select statement is used for most data retrieval in SQL.…Here, I have the SID application open in my browser and I'm going to choose the…world database and, I'm going to enter a simple Select statement, select and…a single quote Hello, World and a closing single quote and a semicolon and…I'll press the go button here and you see the result is Hello, World.…The select statement is used for queries that…will return a value or a set of values.…
And select is used to display the result of any query.…In this case, the query is a literal string with the words Hello, World in it.…But it's still a query.…It just doesn't come from the database.…You could just as easily say select 1 plus 2.…I still have the semi-colon there and you see…that the query is 1.2 and the result is 3.…So now let's get some rows from a table in the database.…If I say select asterisk from and the table name is country,…like that, semi-colon and we get all the rows from the country table.…
You notice the status display says 239 rows…returned and it took 13.5 milliseconds to do that.…
