What are aggregate function in sql explain any 5 aggregate function with example?

Aggregate FunctionsMINreturns the smallest value in a given columnMAXreturns the largest value in a given columnSUMreturns the sum of the numeric values in a given columnAVGreturns the average value of a given columnCOUNTreturns the total number of values in a given columnCOUNT(*)returns the number of rows in a tableAggregate functions are used to compute against a "returned column of numeric data" from your SELECT statement. They basically summarize the results of a particular column of selected data. We are covering these here since they are required by the next topic, "GROUP BY". Although they are required for the "GROUP BY" clause, these functions can be used without the "GROUP BY" clause. For example:SELECT AVG(salary)FROM employee;This statement will return a single result which contains the average value of everything returned in the salary column from the employee table.Another example:SELECT AVG(salary)FROM employee;WHERE title = 'Programmer';This statement will return the average salary for all employees whose title is equal to 'Programmer'Example:SELECT Count(*)FROM employees;This particular statement is slightly different from the other aggregate functions since there isn't a column supplied to the count function. This statement will return the number of rows in the employees table

Why do piecewise functions have restrictions on the x-value?

Piecewise functions have restrictions on the x-values to define specific intervals or conditions under which each piece of the function is applicable. These restrictions ensure that the function is well-defined and behaves consistently within those intervals, allowing for different expressions or rules to apply based on the input value. By segmenting the domain, piecewise functions can model complex behaviors that may not be captured by a single expression.

Function that performs a mathematical function against a group of records?

You can create a function in a programming language like Python or SQL that takes a group of records as input and performs a mathematical operation on them. This function would iterate through the records, apply the specified mathematical operation, and return the result. For example, in SQL you can use aggregate functions like SUM, AVG, MAX, MIN, etc. to perform calculations on groups of records.
