What is a an SQL query block?

An SQL query block is a distinct section of a SQL statement that performs a specific function, such as selecting, updating, or deleting data. It typically includes clauses like SELECT, FROM, WHERE, and ORDER BY, and can be nested within other query blocks to form complex queries. Each block operates independently but can reference results from other blocks, allowing for structured and efficient data manipulation. Query blocks are essential for organizing SQL commands and enabling more advanced database operations.
