What is the difference between SQL Server's ISNULL() and the standard COALESCE()?
Article Introduction:Both ISNULL() and COALESCE() can replace NULL values, but there are key differences. ISNULL() is a SQLServer-specific function that accepts only two parameters, and the result type is determined by the first parameter; COALESCE() is a SQL standard function that supports multiple parameters, returns the first non-NULL value, and determines the result type based on the data type priority. In terms of purpose, COALESCE() should be selected when cross-database or multi-column checking is required, while ISNULL() can be used for simple replacement in SQLServer. Performance-wise, the two are usually similar, but COALESCE() is more stable in subqueries and complex expressions. In addition, COALESCE() is more important when dealing with nested logic

How to get the first day and last day of a month in SQL?
Article Introduction:The method of getting the first and last day of a month in SQL varies from database system to database system, but the core logic is consistent. The idea of ??getting the first day is to adjust the date to the 1st of the month, which can be implemented through DATE_TRUNC (PostgreSQL), DATE_FORMAT (MySQL), DATEADD and DATEDIFF (SQLServer); for the last day, you can use built-in functions such as LAST_DAY (MySQL), EOMONTH (SQLServer), or through the general method of "add one month and reduce one day"; in addition, you need to pay attention to time zone conversion, avoid implicit type conversion, and optimize query performance, such as using range query instead of function processing fields.
