Да, так изучаем и что-то понимаем?) Передача знаний по SQL! Одна из задач тестировщика любого грейда! Больше про задачи и подготовку, присоединяйтесьи смотрите шапку профиля @protestinginfo рассмотрим операторы SELECT, WHERE , DISTINCT Хочу напомнить, что данный язык запросов можно изучить на сайте https://www.sql-ex.ru Оператор SELECT осуществляет выборку из базы данных Команда DISTINCT позволяет выбирать только уникальные значения из базы данных Команда WHERE задает условие, по которому будут выбираться строки из базы данных. SELECT * FROM имя_таблицы SELECT * FROM имя_таблицы WHERE условие SELECT поле1, поле2... FROM имя_таблицы WHERE условие При выборке: SELECT DISTINCT поле FROM имя_таблицы WHERE условие При подсчете: SELECT COUNT(DISTINCT поле) FROM имя_таблицы WHERE условие При суммировании: SELECT SUM(DISTINCT поле) FROM имя_таблицы WHERE условие В запросе можно задавать следующие условия: • сравнение текста; • сравнение численных значений; • логические операции AND (и), OR (или) и NOT (отрицание). #тестировщик #тестированиепо#qa #тестирование #войтивit

Most important Sql interview questions with answer💡 1. What is the difference between UNION and UNION ALL in SQL? Ans - UNION combines and returns distinct rows from multiple SELECT statements, while UNION ALL includes all rows, including duplicates. 2. Explain the difference between a clustered index and a non-clustered index. Ans - A clustered index determines the physical order of data in a table and is generally created on the primary key. A non-clustered index is a separate structure that provides a sorted order of data without altering the physical order of the table. 3. What is a correlated subquery in SQL? Ans- A correlated subquery is a subquery that depends on the outer query for its values. It executes once for each row of the outer query and is usually used for filtering or computing values based on the outer query’s result. 4. What is the purpose of the SQL CASE statement? Ans- The CASE statement allows conditional logic in SQL queries. It evaluates a series of conditions and returns a result based on the first condition that is met, similar to an if-else statement. 5. What is a recursive SQL query? Ans- A recursive SQL query is a query that refers to its own table within the query. It is commonly used to perform hierarchical or self-referencing queries, such as traversing a tree structure or computing recursive aggregates. 6. What are SQL stored procedures, and what are their advantages? Ans- SQL stored procedures are precompiled and stored in a database. They encapsulate a series of SQL statements and are executed by calling the procedure name. Advantages include code reusability, improved performance, enhanced security, and reduced network traffic. 7. What is the difference between a view and a table in SQL? 8. What is a self-join in SQL? 9. What are SQL stored procedures, and what are their advantages? 10. What is the difference between a view and a table in SQL?

SQL లో duplicate values తీసేయడం చాలా సులభం! DISTINCT keyword వాడి ఒకే value ఒక్కసారి మాత్రమే చూపించవచ్చు bro! Topic Notes: DISTINCT keyword SQL లో duplicates values తీసేయడానికి వాడతాం. SELECT query లో DISTINCT వాడితే, same values ఒక్కసారే చూపబడతాయి. Example: ఒక students table లో duplicate ID numbers ఉంటే, DISTINCT వాడి unique ID numbers ని మాత్రమే select చేయవచ్చు. Syntax: SELECT DISTINCT column_name FROM table_name; Hashtags: #SQL #SQLTips #LearnSQL #ChimtuBro Keywords: SQL, DISTINCT, Remove Duplicates, ID Number
