Syntax:

>=

MySQL Version: 8.0

Example: MySQL greater than or equal operator

The following MySQL statement will fetch those publishers from the publisher table who have more than or equal to 10 branch offices.

Sample table: publisher


Code:


-- This query selects specific columns from the 'publisher' table where the number of branches is 10 or more.
SELECT pub_name, country, pub_city, no_of_branch
-- This statement specifies the columns to be retrieved: 'pub_name', 'country', 'pub_city', and 'no_of_branch'.
FROM publisher
-- This part of the query specifies the table from which data is being retrieved, which is 'publisher'.
WHERE no_of_branch >= 10;
-- This clause filters the rows to include only those where the 'no_of_branch' column is greater than or equal to 10.

Explanation:

  • The purpose of this SQL query is to retrieve information about publishers that have 10 or more branches.

  • SELECT pub_name, country, pub_city, no_of_branch: This part of the query specifies the columns to be selected from the 'publisher' table. It includes the publisher's name (pub_name), country (country), city (pub_city), and the number of branches (no_of_branch).

  • FROM publisher: This part specifies the table from which the data is being selected, which is the 'publisher' table.

  • WHERE no_of_branch >= 10: This clause filters the results to include only those rows where the no_of_branch column is greater than or equal to 10. This ensures that only publishers with a significant number of branches are included in the results.

Output:

mysql> SELECT pub_name,country,pub_city,no_of_branch       
    -> FROM publisher           
    -> WHERE no_of_branch>=10;
