Codility-sql-test-solutions SQL Server 2016 Database Reference, including Use the SELECT...FROM SQL function How to use SELECT statements in SQL Server this is tae kim SQL Server SELECT statement by using Functions SecRules - a searchable database of SQL queries and results How to use SELECT statements in SQL Server A: As the comments suggest, this is a learning exercise. Explanation: Why this code is bad (or not a valid SELECT statement): My test failed the first time. I think the reason for this is because of how column names are parsed. In this case, @c, as the column name, has a suffix ".dep". This causes the error "Only numbers, decimal numbers, characters or ascii85 encoded string literals may be used here". Possible solutions to make it valid: In this case, you can use below. SELECT MAX(c.dep) FROM Events e CROSS APPLY(SELECT MAX(dep) dep FROM dbo.TABLE(e.dep)) c WHERE e.type = 1 AND e.deptime BETWEEN '2016-11-14' AND '2016-11-14' If that doesn't work, then use a subquery in a union with the invalid one. SELECT MAX(c.dep) FROM (SELECT MAX(dep) dep FROM dbo.TABLE(@c.dep)) c If you want to get a row, use TOP or order by: SELECT MAX(c.dep) FROM Events e CROSS APPLY(SELECT MAX(dep) dep FROM dbo.TABLE(e.dep)) c WHERE e.type = 1 AND e.deptime BETWEEN '2016-11-14' AND '2016-11-14' ORDER BY e.deptime DESC Notes: SQL Server doesn't support window functions like Sort your data alphabetically (a.k.a. "Sorting problem") Add order to the following three tables (a.k.a. "Sorting problem"). Products, Categories, and Orders. Problem sets at Challenges. The Mathematical Puzzlers "Heads or Tails"? 1. Quickly find out if the sequence of roll of the dice has the appearance of "Heads or Tails" before throwing any set of dice. 2. Write a program that rolls a set of dice and find out if the number of heads comes before Tails. 3. The sequence of numbers of the last twenty rolls of a set of 6 dice are : 1,2, 2, 3, 3, 4, 4, 5, 5, 6, 6, 6, 5, 4, 4, 4, 3, 3, 3, 2, 2, 2. . 5-10. Find an integer x, such that the product of x, x, x, etc. equals x!. How to code questions? For each test, we will first add the "tabulation" of the question : the code fragment to be tested, the challenge name, the number of points and the time constraints. Then, we will write the programming task based on this tabulation. We will need a system to manage the questions added in this documentation. . We’ll start with a quick introduction to the SCORM format for Learning Objects (web 2.0). We’ll then explain the benefits of SCORM over other learning object formats, including iTunes U. We start by talking about the 3 main elements of SCORM. First, there is the complete SCORM specification. Our objective is to test your understanding of the concepts by asking questions. We'll discuss the additional elements of the SCORM specification, including all of its aspects and its internals, including the complete implementation of SCORM contents. The SCORM specification is a standard that is used in the creation of e-learning courses, with a focus on studying abroad and English language learning. As with any programming language, you'll need to understand the logic behind each statement. This way, you'll be able to solve problems related to the SCORM specification. To help you improve, you'll access our forum! Discuss questions with your peers, get access to free support videos, share your solutions, etc. Keep track of 55cdc1ed1c
