MS SQL Server offers robust features for structured data management. This article introduces efficient techniques for extracting date and time from the datetime function, focusing on the CONVERT and CAST functions.
Simplified Date and Time Extraction Techniques
The datetime data type in MS SQL Server holds date and time together. To fetch the current datetime, use SELECT getdate();. For date extraction, CONVERT is handy, e.g., SELECT CONVERT(date, getdate()); extracts just the date. For time, SELECT CONVERT(VARCHAR, getdate(), 108); yields the time in hh:mm:ss format. The CAST function also plays a crucial role, with SELECT CAST(getdate() AS date); isolating the date from datetime.
Concise FAQs
- How is CONVERT used? It's used for data type conversion and datetime value extraction.
- Utilizing CAST for datetime extraction? It changes the data type of an expression, facilitating the extraction of either date or time from datetime.
