Milliseconds DESC Code language: SQL (Structured Query Language) ( sql ) In this case, you need to add the Milliseconds column to the ORDER BY clause as follows: SELECT name, Suppose you want to sort the sorted result (by AlbumId) above by the Milliseconds column in descending order. SQLite uses ASC by default so you can omit it in the above statement as follows: SELECT The result set now is sorted by the AlbumId column in ascending order as shown in the screenshot. Suppose you want to sort the result set based on AlbumId column in ascending order, you use the following statement: SELECT name,Īlbumid ASC Code language: SQL (Structured Query Language) ( sql ) The SELECT statement that does not use ORDER BY clause returns a result set that is not in any order. Tracks Code language: SQL (Structured Query Language) ( sql ) Suppose, you want to get data from name, milliseconds, and album id columns, you use the following statement: SELECT name, Let’s take the tracks table in the sample database for the demonstration. You can sort the result set using a column that does not appear in the select list of the SELECT clause. Then, it sorts the sorted rows using the second column, and so on. In other words, the ORDER BY clause sorts the rows using the first column in the list. The ORDER BY clause sorts rows using columns or expressions from left to right. In case you want to sort the result set by multiple columns, you use a comma (,) to separate two columns. In other words, it sorts the result set in the ascending order by default. If you don’t specify the ASC or DESC keyword, SQLite sorts the result set using the ASC option. In this syntax, you place the column name by which you want to sort after the ORDER BY clause followed by the ASC or DESC keyword. It allows you to sort the result set based on one or more columns in ascending or descending order. The ORDER BY clause comes after the FROM clause. To sort the result set, you add the ORDER BY clause to the SELECT statement as follows: SELECTĬolumn_2 DESC Code language: SQL (Structured Query Language) ( sql ) If you use the SELECT statement to query data from a table, the order of rows in the result set is unspecified. It means that the rows in the table may or may not be in the order that they were inserted. SQLite stores data in the tables in an unspecified order.

Subquery can be used in conjunction with the DELETE statement like with any other statements mentioned above.įollowing example deletes records from COMPANY table for all the customers whose AGE is greater than or equal to 27.Summary: in this tutorial, you will learn how to sort a result set of a query using SQLite ORDER BY clause. This would impact two rows and finally COMPANY table would have the following records − WHERE AGE IN (SELECT AGE FROM COMPANY_BKP
#SQLITE STUDIO ORDER BY MULTIPLE UPDATE#
Either single or multiple columns in a table can be updated when using a subquery with the UPDATE statement.Īssuming, we have COMPANY_BKP table available which is a backup of COMPANY table.įollowing example updates SALARY by 0.50 times in COMPANY table for all the customers, whose AGE is greater than or equal to 27. The subquery can be used in conjunction with the UPDATE statement. To copy the complete COMPANY table into COMPANY_BKP, following is the syntax − INSERT INTO table_name ) ]Ĭonsider a table COMPANY_BKP with similar structure as COMPANY table and can be created using the same CREATE TABLE using COMPANY_BKP as the table name. The selected data in the subquery can be modified with any of the character, date, or number functions.įollowing is the basic syntax is as follows − The INSERT statement uses the data returned from the subquery to insert into another table.
Subqueries can also be used with INSERT statements. Subqueries can be used with the SELECT, INSERT, UPDATE, and DELETE statements along with the operators such as =,, >=, SELECT * A Subquery or Inner query or Nested query is a query within another SQLite query and embedded within the WHERE clause.Ī subquery is used to return data that will be used in the main query as a condition to further restrict the data to be retrieved.
