MySQL Select Record

The SELECT statement in MySQL is used to fetch data from one or more tables. We can retrieve records of all fields or specified fields that match specified criteria using this statement. It can also work with various scripting languages such as PHP, Ruby, and many more.

It is the most commonly used SQL query. The general syntax of this statement to fetch data from tables are as follows:

SELECT field_name1, field_name 2,... field_nameN   
FROM table_name1, table_name2...  
[WHERE condition]  
[GROUP BY field_name(s)]  
[HAVING condition]   
[ORDER BY field_name(s)]  
[OFFSET M ][LIMIT N];
