- PATHS is a table that contains information about paths on a number line. The structure of PATHS is as follows, where x1 and x2 represent that there is a path from Coordinate x1 to Coordinate x2 (You can't move from Coordinate x2 to Coordinate x1 ). NAME ΤΥΡE NULLABLE X1 INT FALSE X2 INT FALSE Problem Please write an SQL statement that returns the beginning and end point of each path in PATHS . Sort them by the value of the beginning point in ascending order. Constraints • In the case where a direct path from Coordinate a to Coordinate b is available, no path from Coordinate b to Coordinate a will be given. |x1-x2| = 1 • No path will overlap with one another. Example Suppose that PATHS is as follows: x1 x2 1 2 2 3 4 7 7 6 This table can be visualized as follows: START END END START 7 8. 9 Therefore, your SQL statement must return the following: start end 1 4 8 6//trying to make recursive SQL statement to get the days of the week , can you tell me what does not work in this query: WITH cte_number (counter, weekday) AS(SELECT 0, Datename(DW,0) UNION ALLSELECTcounter+1, Datename(DW, counter+1)FROM cte_numberwhere counter<6) select weekday from cte_number; //thanks for you assistanceIf I have a table in sql database phpmyadmin the table's column : ID Name Salary City 1 John 200 London 2 Eric 300 Paris 3 Michael 450 Milan in php we have to create dropdown menu show the names coming from the database when the user choose a name from the menu will show the salary for this person . one more thing there is no sumbit button , I mean when the user choose a name from the dropdown menu will show the salary without any click. would you help to create php code and javascript if it's needed.
- Database: https://www.w3schools.com/sql/trysql.asp?filename=trysql_select_allSQL A table Products have: a name (TEXT) a description (TEXT) a unit cost stored in cents (INTEGER) and of course we also add an id column to identify them. Separately, we'd like to track the number of items in stock for each product. To do so we'll have a store and an inventory table. Stores have just an id and a name. Then, our inventory table should combine stores and products, listing how much of each product each store has in stock. a product_id (INTEGER) a store_id (INTEGER) a quantity (INTEGER) in stock Now we can insert some stores, products and inventory into our database. There are 2 stores -- one called NY and one called NJ. There are 2 products we are concerned with. Their names are sneakers, costing $220 (remember this is dollars!) and boots costing $350. Use any description for each that you'd like. NY has 4 sneakers in stock and 3 boots. NJ has 5 sneakers in stock and no boots. Insert the above data into the tables you have created.PL/SQL Question I need to build pl/sql block that prompts a user for the number of visitors each day for the past 5 days and then displays the average number of visitors per day. For example; day 1: 19 day 2: 21 day 3: 23 ... The avg number of visitors is: ___ like this.
- A cake shop named "Whisk" has an online presence. It has multiple flavors of cakes supplied by various vendors. The manager wants to know the cost of the available quantity.
