SQL Tutorial will guide us another arithmetic function is COUNT. This allows us to COUNT up the number of row in a certain table. The syntax for this key work COUNT statement is as under.

Syntax for SQL Cont Statement

SELECT COUNT("column_name")
FROM "table_name"

For example, if we want to find the number of employees entries in our table,

Table Employees

FirstName	LastName	Email	DOB	Phone
Austin	Hennery	austin.it@gamail.com	24/11/1978	446 102-2222
Creston	Narvon	narvon_crest@hotmail.com	22/04/1976	443 325-4545
Kate	Bladen	kbladen@usa.net	01/05/1980	326 503-3232
Angela	Hennery	julieee@yahoo.co.uk	11/12/1977	326 323-8888
Bobbi	Ferguson	bobi123@kiwibox.com	10/02/1970	506 252-9875
Cute	Alfa	cafa@gmail.com	19/05/1972	506 272-4566

SELECT COUNT(FirstName)
FROM Employees

Result of SQL Count Statement:

Count(store_name)
6

SQL COUNT and DISTINCT Statements can be used together in a statement to fetch the number of distinct entries in a table. For example, if we want to find out the number of distinct employees Last Name, we'd type,

Example of SQL Count and Distinct Statements

SELECT COUNT(DISTINCT LastName)
FROM Employees

Result of SQL Count and Distinct statements:

Count(DISTINCT LastName)
5

Because the Last name of two employees Austin and Angela are same that's whey the last result is 5 even we have 6 records in our table of Employees the SQL Distinct key word show the unique recodes in a table. Hope this section of SQL Tutorial coves the all needs for learning SQL Count And SQL Distinct Statements.
