For every invoice, display the invoice number, invoice date and the total dollar amount for all products purchased in the invoice, ordered by invoice number in descending order and then by invoice date in ascending order. Here you will use an aggregate SUM(x,y) function in your SELECT clause to calculate the total dollar amount (a calculated field – name it TOTAL). Don’t forget to join on the tables as well. [hint: you should have 8 rows of output ordered properly]. My code is as follows: select inv_number, inv_date, sum(line_price) as 'total' from invoice, line where invoice.inv_number = line.inv_number order by inv_number desc, inv_date asc ; I am getting this error: ORA-00923: FROM keyword not found where expected Any recommendations on what I am doing wrong?
SQL
SQL stands for Structured Query Language, is a form of communication that uses queries structured in a specific format to store, manage & retrieve data from a relational database.
Queries
A query is a type of computer programming language that is used to retrieve data from a database. Databases are useful in a variety of ways. They enable the retrieval of records or parts of records, as well as the performance of various calculations prior to displaying the results. A search query is one type of query that many people perform several times per day. A search query is executed every time you use a search engine to find something. When you press the Enter key, the keywords are sent to the search engine, where they are processed by an algorithm that retrieves related results from the search index. Your query's results are displayed on a search engine results page, or SER.
