Question

I have two columns in my MySQL table total and dollars. I need to convert my dollars into rupees and store it in my total field. Can I multiply live dollar rates and store the result?

I need a SQL query for a mathematical function which is like this:

total = dollars * current_dollar_rate_in_rupees

Can I make this conversion dynamic? If so how and what would be my SQL query?

Answer 1

Multiplying Two Columns in SQL Server

So just store the value that is giving by this query in your database as ‘total’

SELECT dollars * current_dollar_rate_in_rupees from tablename
