SQL is a special-purpose programming language designed for managing data in a relational database, and is used by a huge number of apps and organizations. Learn for free about math, art, computer programming, economics, physics, chemistry, biology, medicine, finance, history, and more Unlike standard SQL, BigQuery uses the comma as a UNION ALL operator rather than a CROSS JOIN operator. This is a legacy behavior that evolved because historically BigQuery did not support CROSS JOIN and BigQuery users regularly needed to write UNION ALL queries. In standard SQL, queries that perform unions are particularly verbose SQL functions are built into Oracle Database and are available for use in various appropriate SQL statements. Do not confuse SQL functions with user-defined functions written in PL/SQL. If you call a SQL function with an argument of a datatype other than the datatype expected by the SQL function, then Oracle attempts to convert the argument to. Spark SQL is developed as part of Apache Spark. It thus gets tested and updated with each Spark release. If you have questions about the system, ask on the Spark mailing lists.
