If you enter a Connection name that already exists, the Database Engine 3.0 doesn't establish a new connection. By default, the Database Engine 3.0 uses the DSN value as connection name. Name of the connection that you want to open. The Module TBox DB Open Connection has the following ModuleAttributes: The Database Engine 3.0 uses the most recently established connection for your tests.Īlternatively, you can specify a different connection with the Module Current Connection. You can open multiple database connections. The Module TBox DB Open Connection allows you to open a connection to a database. If you use the Database Engine 3.0 Module to open a connection, you must perform your database operations and then close the connection with Database Engine 3.0 Modules. The Database Engine 3.0 does not support mixed TestCases. You can view EDUCBA’s recommended articles for more information.The folder TBox XEngines ->Database in the Standard subset contains Modules that perform specific tasks for the Database Engine 3.0. We hope that this EDUCBA information on “SQL Order by Count” was beneficial to you. ORDER BY count(DISTINCT salesperson) DESC, count(product_id) ASC SELECT store_state,Ĭount( DISTINCT salesperson) as "total_salespeople" ORDER BY COUNT() statement with more than one count() functions Example #5įind the number of sales and unique salespersons for each store location, arranged from highest to lowest count of salespersons and from lowest to highest by number of sales in case of a tie. In this specific case, even though there are 11 product_ids, the count only includes 9 unique ones. When we use the DISTINCT keyword with COUNT, it returns the count of unique records in the specified column. SELECT salesperson, count( DISTINCT product_id) Example #4įind the number of different products each salesperson sells, arranged from lowest to highest. ORDER BY COUNT() statement with COUNT(DISTINCT field_name) function. Example #3įind the number of sales made in each store location, arranged from lowest to highest. To sort a given result set in descending order, we use the DESC keyword. Example #2įind the number of sales each salesperson makes and arrange the result from highest to lowest. The query first groups the results by salesperson then counts the number of product_ids corresponding to each group and finally sorts the result set according to the value returned by the count() function. SQL queries to illustrate the basic functionality of ORDER BY COUNT() Example #1įind the number of sales each salesperson makes and arrange from lowest to highest. The COUNT() function returns the total number of rows in the result set. Now we are all set to discuss a few examples based on ORDER BY COUNT() with the help of the product_details table.īasic functionality of COUNT() function SELECT COUNT(*) Product_id, sale_date, sale_amount, salesperson, store_state) Let’s insert the following values in it to work with. Store_state character varying(255) NOT NULL, Salesperson character varying(255) NOT NULL, We can use the following CREATE TABLE statement to create the table. This table contains details about sales, such as product_id, sale_date, etc., for a departmental store. To illustrate the working of the ORDER BY COUNT() statement, let us create a dummy table named “product_details”. Now that we have learned the syntax and parameters for writing ORDER BY clauses, let’s explore a few examples to gain a better understanding of the concept.
