Understanding Date and Time Extraction in MS SQL Server

MS SQL Server, a powerful RDBMS, facilitates complex data management and analysis. This guide highlights key methods for extracting date and time from datetime values, employing the CONVERT and CAST functions for efficient data manipulation.

Key Methods for Date and Time Extraction

Extracting datetime values is essential for data analysis. The SELECT getdate(); query fetches current date and time. The CONVERT function, with queries like SELECT CONVERT(date, getdate());, extracts the date part, while SELECT CONVERT(VARCHAR, getdate(), 108); gets the time. Additionally, the CAST function, through SELECT CAST(getdate() AS date);, also facilitates date extraction from datetime values.

Streamlined FAQs

• How does CONVERT work? It changes data types and helps in extracting specific parts from datetime values.

• What's the role of CAST in datetime extraction? CAST alters the expression's data type, useful in isolating date or time from datetime.
