MySQL - SELECT Statement

The SELECT statement is used to select or retrieve the data from one or more tables.

The SELECT statement is used to retrieve all the rows from a table or as well as to retrieve only those rows that satisfy a certain condition


Syntax : SELECT Column


SELECT column1, column2, column3, ...
FROM table_name;  

Here, column1, column2, column3, ... are the field names of the table you want to select data.

If you want to select all the fields available in the table, use the following syntax:


Syntax : SELECT All


SELECT * FROM table_name;  

Let's put these statements into real use.

We've a table named Students in our database that contains the following records:

ROLL_NO NAME SUBJECT
1 Will C++
2 SAM Python
3 Sara HTML
4 Rim Java
5 Micheal SQL
6 Lara



Example : SELECT Column


SELECT ROLL_NO, NAME FROM Students;

The above SELECT statement selects two columns(ROLL_NO and NAME) from the above Students table.

Result

ROLL_NO NAME
1 Will
2 SAM
3 Sara
4 Rim
5 Micheal
6 Lara

Now we will select all the fields available in the table.


Example : SELECT All


SELECT * FROM Students;

The above SELECT statement selects all columns from the Students table.

Result

ROLL_NO NAME SUBJECT
1 Will C++
2 SAM Python
3 Sara HTML
4 Rim Java
5 Micheal SQL
6 Lara
