If you want to know how to learn SQL queries, you must first have a basic understanding of the SQL language and SQL statements. Database administrators use specific codes to filter out the information they want. Queries allow database users to filter large amounts of data, which is stored within a database, by a specific set of criteria.
For example, Select statements are used to identify the files you want to search, From statements identify the tables to search and Where statements identify the specific field within the table to search. Queries can be filtered further by using additional codes, such as Or statements, In statements, Between statements and Like statements. Administrators also can specify how the results are displayed with codes like Order by statements and Desc (descending) statements.
