How to sort JavaScript Object arrays by specified attributes and sorting directions? javascript Array Introduction In a data-centric Information System, it is common to present data in the form of tables. Sorting data is essential. Sorting can be divided into sorting by a single field and sorting by multiple fields in different sorting directions. Single-field sorting has many limitations and cannot meet users' requirements for changing data concerns. Multi-field sorting can make up for this def

SQL-92 syntax. Use left Outer Join Assume that the authors table and the publishers table are joined in the city column. The results only show the author of the publisher's city (Abraham Bennet and Cheryl Carson in this example ). To include all authors in the results, regardless of whether the publisher lives in the same city, use the SQL-92 to connect left out. The following are the query results of the left Outer Join of transact-SQL: Use pubs Select a. au_fname, A. au_lname, P. pub_nam

The so-called subquery is the embedding of several small queries within a query.
