I guess, if I use ASC or DESC in queries, I should add them to index. Where is info about how I should use them I cant find it.
So, there are three options: no-sort, ASC, DESC when creating index.
Let’s take look at some examples of sorting result sets using the ORDER BY clause. specifies the results in descending order. Each column name or expression can be followed by one of the 'ASC' or 'DESC' keywords to indicate sort order. You can sort by one column in ascending order and another column in descending order. To sort multiple columns, you just need to specify additional columns in the ORDER BY clause. In addition, every order clause can specify whether NULL. If you don’t specify any keyword explicitly, the ORDER BY clause sorts the result set in ascending order by default. Given a table Employee having columns empName and empId, what will be the result of the SQL query below select empName from Employee order by 2 asc. The ORDER BY clause sorts the rows on the sorting criteria in either ascending or descending order. To sort a result set in ascending order, you use ASCkeyword, and in descending order, you use the DESCkeyword. SQLite ORDER BY clause is used to sort the data in an ascending or descending order, based on one or more columns. It enables users to arrange the data frame in descending or ascending order depending solely on a single. The ORDER BY clause allows you to sort the result set by a column or an expression with a condition that the value in the column or the returned value of the expression must be sortable i.e., the data type of the result must be the character, numeric or date-time. The ORDER BY command is a SQL query that sorts records.
