In SQL, you can count the number of columns with the same value by utilizing the COUNT() function combined with a GROUP BY clause. This allows you to group the rows based on a specific column and count the occurrences of the same value within that column. Here’s how you can do it:<\/p>\n

    <\/p>\n
  1. Write a SELECT statement to specify the columns you want to display.<\/li>\n

    <\/p>\n

  2. Use the COUNT() function in combination with the column you want to count.<\/li>\n

    <\/p>\n

  3. Include a GROUP BY clause to group the rows based on a specific column.<\/li>\n

    <\/p>\n

  4. Execute the query and review the results.<\/li>\n

    \n<\/ol>\n

    Here’s an example to illustrate the process. Let’s say you have a table called “employees” with columns “name” and “department”. You want to count the number of employees in each department:<\/p>\n

    SELECT department, COUNT(name)
    \nFROM employees
    \nGROUP BY department;
    \n<\/code><\/pre>\n
    The above query will display the department names and the number of employees in each department. For instance, if you have two employees in the “Marketing” department, three employees in the “Sales” department, and one employee in the “Finance” department, the result will be:<\/p>\n
    +------------+--------------+
    \n| department | COUNT(name)  |
    \n+------------+--------------+
    \n| Marketing  |      2       |
    \n| Sales      |      3       |
    \n| Finance    |      1       |
    \n+------------+--------------+
    \n<\/code><\/pre>\n
