How can you select specific columns from a table?

To select specific columns from a table in SQL, you need to specify the column names you want in the SELECT statement.

Here's the basic syntax to select specific columns from a table:

SELECT column1, column2, ... 
FROM table_name;
  • column1, column2, etc.: Replace these placeholders with the names of the columns you want to retrieve.
  • table_name: Replace this with the name of the table from which you want to select the specified columns.

For example, if you have a table named "Employees" with columns "EmployeeID," "FirstName," and "LastName," and you want to retrieve only the "FirstName" and "LastName" columns, your SQL query would look like this:

SELECT FirstName, LastName 
FROM Employees;

Executing this query will return only the specified columns ("FirstName" and "LastName") from the "Employees" table, and all rows will include these columns' data.
