Write a query to arrange a column in descending order
The resultset can be sorted using one or more columns too. Most of the database systems sort the records in ascending order by default if not specified. Here we'll see how to write order by query in codeigniter framework to sort the database records. The method takes up two parameters, first one is the table column name and second one is optional and specifies if the column values should be sorted in ascending or decending order. Also note that the query doesn't specify if 'BookName' should be sorted in ascending or descending order. This codeigniter order by query explicitly specifies to sort the resultset using 'Author' column in ascending order.

In most cases, the SQL server returns records in the same order they are added to the database. There is no guarantee that records are returned in a specific order when you don't use sorting options in SQL. In addition to sorting, you also use filtering options to return only specific records that match your requirements. You can sort records in ascending or descending order, and you can sort records based on multiple columns. SQL lets you sort alphabetically, numerically or chronologically.
When you use the SELECT statement to query data from a table, the order which rows appear in the result set may not be what you expected. In some cases, the rows that appear in the result set are in the order that they are stored in the table physically. However, in case the query optimizer uses an index to process the query, the rows will appear as they are stored in the index key order.
By default, the rows in the resulting dataset of query are not necessarily arranged in any specific order. You can sort the rows in the dataset in ascending or descending order by one or more selected columns in the query. For example, if the query retrieves the quantity of items in sales orders for each customer, then you could sort the results in alphabetical order by the customer name, or you could sort the results by the quantity of items from the highest value to the lowest value. To sort query results, you modify the OrderBy Property of the query object. In the development environment, on the Tools menu, choose Object Designer.
