Select Statement or Select Query in SQL Explained with Examples

Select Statement

The SELECT statement is used for the selection of data from a database. This statement is widely used both by the database administrators as well as developers.


SELECT col_name_1, col_name_2, …, col_name_n

FROM tbl_name;

In the above syntax, SELECT keyword is a command understood by DBMS to fetch data. Col_name_1 and col_name_2 upto col_name_n are the columns to be retrieved. Next, the keyword FROM is a command to specify the source Table and finally, tbl_name is the target table, from where the records are to be fetched.

Another syntax that is quite common in use, is:


FROM tbl_name;

Here too, the SELECT keyword is a command to fetch data, FROM keyword is a command to specify the source table and tbl_name is the target table. The new element is * which is a wildcard and that refers to the selection of all the columns residing within the target table.


SELECT ID, C_Name, Status FROM Customers
