How to update specific date parts (year month day hour) in ClickHouse ®

In ClickHouse, Date and DateTime values are immutable, meaning direct modification of components like year, month, or day isn't possible; instead, new values are generated using specialized functions for date manipulation. The guide covers a wide array of these functions, such as addYears, addMonths, addDays, and addHours, which allow for arithmetic manipulation of dates, alongside toStartOfInterval functions for resetting specific components to their starting values. It also addresses timezone considerations and edge cases like leap years, emphasizing the importance of handling these factors in data manipulation. The text outlines practical applications of these functions, including time-series analytics and API development with Tinybird, showcasing how to dynamically adjust and normalize temporal data for real-time analytics. Additionally, it highlights the performance benefits and differences between various functions, such as addX functions for arithmetic shifts and toStartOfX functions for normalization, and discusses the operational aspects of running ClickHouse at scale with Tinybird's managed services.
