Aprašymas

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A Common Table Expression, or CTE, (in SQL) is a temporary named result set, derived from a simple query and defined within the execution scope of a SELECT, INSERT, UPDATE, or DELETE statement. CTEs can be thought of as alternatives to derived tables (subquery), views, and inline user-defined 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 (however, there is some debate about its expansion), 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.
