The HAVING Clause is almost typically used in conjunction with the GROUP BY Clause. The HAVING Clause limits the amount of data that can be stored on group records rather than individual entries. In a single query, both WHERE and HAVING can be utilised.
In a SELECT statement, the SQL Aggregate BY clause is used to collect data from numerous records and group the results by one or more columns. A clause in a SELECT statement that separates the query result into groups of rows, usually so that one or more aggregations can be performed on each group.
You can use GROUP BY at the conclusion of a SELECT query to group the selected columns by a certain column value. This is frequently used in conjunction with aggregate functions, such that the output shows the result of an aggregation function for rows with specific column values.
The HAVING clause is similar to the WHERE clause in that it applies to entire groups (that is, the rows in the result set that represent groups), whereas the WHERE clause applies to individual rows. A query can have both a WHERE and a HAVING clause, but they cannot be used interchangeably.
The clause "SELECT" cannot be used without the clause "FROM."
