Answer 1

Answer:

"From, where, select ,order by" is the correct answer for the above question.

Explanation:

• When a user creates a query in comparison of "SELECT, FROM, WHERE ORDER BY", then the query will execute in the "From, where, select, order by" order.
• Firstly form clause will execute because it holds the name of the table which defined the address of the data which needs to fetch.
• Then the where clause will execute which is used to filter the data. It states the correct location of the data in the table.
• Then the select clause is executed because it works to fetch the data and gives the output to the user.
• Then the order by clause is executed because it states the data in ascending or descending order.
