From requires either one or three arguments

Query: from requires either one or three arguments

Explanation:

The from keyword in SQL is used to specify the table(s) from which data is selected. It is usually used in conjunction with the SELECT statement. The from keyword requires either one argument (table name) or three arguments (table name, join type, and join condition).

If only one argument is provided, the from clause specifies the table from which to select data. For example:

    SELECT * FROM customers;
  

In the above example, the from clause has one argument (customers). It retrieves all rows from the customers table.

If three arguments are provided, the from clause specifies joining multiple tables together. For example:

    SELECT * FROM orders
    JOIN customers ON orders.customer_id = customers.id;
  

In the above example, the from clause has three arguments (orders, JOIN, and the join condition). It retrieves data from the orders table by joining it with the customers table using the common customer_id column.

So, to fix the error “from requires either one or three arguments,” ensure you provide the correct number of arguments and use the appropriate syntax depending on your query’s purpose.
