The HAVING clause can include aggregate functions and logical operators to filter out groups that meet specific conditions. Its syntax is as follows:<\/p>\n<pre class=\"post-pre\"><code>SELECT column1, column2, ...\r\nFROM table\r\nGROUP BY column1, column2, ...\r\nHAVING condition;\r\n<\/code><\/pre>\n<p>Condition is an expression used to filter the grouped results. This expression can combine aggregate functions (such as COUNT, SUM, AVG, etc.) and logical operators (such as AND, OR, NOT, etc.) to determine the groups that meet the condition.<\/p>\n<p>For example, let&#8217;s say we have a product table that includes product names and prices. We want to find products with prices greater than 100. We can use the following SQL query:<\/p>\n<pre class=\"post-pre\"><code>SELECT product_name, SUM(price) as total_price\r\nFROM products\r\nGROUP BY product_name\r\nHAVING SUM(price) &gt; 100;\r\n<\/code><\/pre>\n<p>This query first groups items by their names, then calculates the total price for each group. It then filters out groups with a total price greater than 100 using the HAVING clause, and finally returns the names of the items and their total prices that meet the condition.<\/p>\n<p>In summary, the HAVING clause in Oracle is used to filter the grouped results, and conditions can be defined using aggregate functions and logical operators.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In Oracle, the HAVING clause is used to filter the results of grouped data after the GROUP BY clause.
