Aprašymas

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A HAVING clause in SQL specifies that an SQL SELECT statement should only return rows where aggregate values meet the specified conditions. It was added[when?] to the SQL language because the WHERE keyword could not be used with aggregate functions. SQL (officially pronounced /¿¿skjü¿¿l/ like "S-Q-L" but often pronounced /¿si¿kw¿l/ like "sequel"), often referred to as Structured Query Language, is a database computer language designed for managing data in relational database management systems (RDBMS), and originally based upon relational algebra. Its scope includes data insert, query, update and delete, schema creation and modification, and data access control.
