Exists and Between Operators in Sql Server

EXISTS Operator :
In SQL Server, the EXISTS operator is used to check for the existence of rows returned by a subquery within the main query. It returns a Boolean value of TRUE if the subquery returns any rows, and FALSE if the subquery does not return any rows.
The subquery can be any valid SQL query that returns a result set. The main query will execute and return rows only if the subquery returns at least one row.

BETWEEN Operator :
In SQL Server, the BETWEEN operator is used to filter data within a specified range. It allows you to retrieve rows where a particular column's value is within a given range of values, inclusively. The BETWEEN operator is commonly used with numerical, date, and time data types.

It's important to note that the BETWEEN operator can be used with various data types, including numerical, date, and time types. However, when dealing with date and time data, make sure the format is consistent and correctly interpreted by SQL Server to avoid unexpected results.

Additionally, be cautious with inclusive/exclusive boundaries when working with date and time data types. If you need to include or exclude the upper or lower boundary, you may need to adjust your query accordingly.
