SQL Basics for Beginners: Must-Know Concepts 1. What is SQL? SQL (Structured Query Language) is a standard language used to communicate with databases. It allows you to query, update, and manage relational databases by writing simple or complex queries. 2. SQL Syntax SQL is written using statements, which consist of keywords like SELECT, FROM, WHERE, etc., to perform operations on the data. - SQL keywords are not case-sensitive, but it's common to write them in uppercase (e.g., SELECT, FROM). 3. SQL Data Types Databases store data in different formats. The most common data types are: - INT (Integer): For whole numbers. - VARCHAR(n) or TEXT: For storing text data. - DATE: For dates. - DECIMAL: For precise decimal values, often used in financial calculations. 4. Basic SQL Queries Here are some fundamental SQL operations: - SELECT Statement: Used to retrieve data from a database.
     SELECT column1, column2 FROM table_name;
     
- WHERE Clause: Filters data based on conditions.
     SELECT * FROM table_name WHERE condition;
     
- ORDER BY: Sorts data in ascending (ASC) or descending (DESC) order.
     SELECT column1, column2 FROM table_name ORDER BY column1 ASC;
     
- LIMIT: Limits the number of rows returned.
     SELECT * FROM table_name LIMIT 5;
     
5. Filtering Data with WHERE Clause The WHERE clause helps you filter data based on a condition:
   SELECT * FROM employees WHERE salary > 50000;
   
You can use comparison operators like: - =: Equal to - >: Greater than - <: Less than - LIKE: For pattern matching 6. Aggregating Data SQL provides functions to summarize or aggregate data: - COUNT(): Counts the number of rows.
     SELECT COUNT(*) FROM table_name;
     
- SUM(): Adds up values in a column.
     SELECT SUM(salary) FROM employees;
     
- AVG(): Calculates the average value.
     SELECT AVG(salary) FROM employees;
     
- GROUP BY: Groups rows that have the same values into summary rows.
     SELECT department, AVG(salary) FROM employees GROUP BY department;
     
7. Joins in SQL Joins combine data from two or more tables: - INNER JOIN: Retrieves records with matching values in both tables.
     SELECT employees.name, departments.department
     FROM employees
     INNER JOIN departments
     ON employees.department_id = departments.id;
     
- LEFT JOIN: Retrieves all records from the left table and matched records from the right table.
     SELECT employees.name, departments.department
     FROM employees
     LEFT JOIN departments
     ON employees.department_id = departments.id;
     
8. Inserting Data To add new data to a table, you use the INSERT INTO statement:
   INSERT INTO employees (name, position, salary) VALUES ('John Doe', 'Analyst', 60000);
   
9. Updating Data You can update existing data in a table using the UPDATE statement:
   UPDATE employees SET salary = 65000 WHERE name = 'John Doe';
   
10. Deleting Data To remove data from a table, use the DELETE statement:
    DELETE FROM employees WHERE name = 'John Doe';

If youโ€™re a Data Analyst, chances are you use ๐’๐๐‹ every single day. And if youโ€™re preparing for interviews, youโ€™ve probably realized that it's not just about writing queries it's about writing smart, efficient, and scalable ones. 1. ๐๐ซ๐ž๐š๐ค ๐ˆ๐ญ ๐ƒ๐จ๐ฐ๐ง ๐ฐ๐ข๐ญ๐ก ๐‚๐“๐„๐ฌ (๐‚๐จ๐ฆ๐ฆ๐จ๐ง ๐“๐š๐›๐ฅ๐ž ๐„๐ฑ๐ฉ๐ซ๐ž๐ฌ๐ฌ๐ข๐จ๐ง๐ฌ) Ever worked on a query that became an unreadable monster?

Use them when you want to filter based on results of another query or isolate logic step-by-step before joining with the big picture. 4. ๐ˆ๐ง๐๐ž๐ฑ๐ž๐ฌ & ๐๐ฎ๐ž๐ซ๐ฒ ๐Ž๐ฉ๐ญ๐ข๐ฆ๐ข๐ณ๐š๐ญ๐ข๐จ๐ง Query taking forever? Look at your indexes. Index the columns you use in JOINs, WHERE, and GROUP BY.

Learn how to join a table to itself or use recursive CTEs to navigate parent-child relationships effectively. You donโ€™t need to memorize 100 functions. You need to understand 10 really well and apply them smartly. These are the concepts I keep going back to not just in interviews, but in the real world where clarity, performance, and logic matter most.

1. What is the difference between the RANK() and DENSE_RANK() functions? The RANK() function in the result set defines the rank of each row within your ordered partition. If both rows have the same rank, the next number in the ranking will be the previous rank plus a number of duplicates. If we have three records at rank 4, for example, the next level indicated is 7. The DENSE_RANK() function assigns a distinct rank to each row within a partition based on the provided column value, with no gaps. If we have three records at rank 4, for example, the next level indicated is 5. 2. Explain One-hot encoding and Label Encoding. How do they affect the dimensionality of the given dataset? One-hot encoding is the representation of categorical variables as binary vectors. Label Encoding is converting labels/words into numeric form. Using one-hot encoding increases the dimensionality of the data set. Label encoding doesnโ€™t affect the dimensionality of the data set. One-hot encoding creates a new variable for each level in the variable whereas, in Label encoding, the levels of a variable get encoded as 1 and 0. 3. What is the shortcut to add a filter to a table in EXCEL? The filter mechanism is used when you want to display only specific data from the entire dataset. By doing so, there is no change being made to the data. The shortcut to add a filter to a table is Ctrl+Shift+L. 4. What is DAX in Power BI? DAX stands for Data Analysis Expressions. It's a collection of functions, operators, and constants used in formulas to calculate and return values. In other words, it helps you create new info from data you already have. 5. Define shelves and sets in Tableau? Shelves: Every worksheet in Tableau will have shelves such as columns, rows, marks, filters, pages, and more. By placing filters on shelves we can build our own visualization structure. We can control the marks by including or excluding data. Sets: The sets are used to compute a condition on which the dataset will be prepared. Data will be grouped together based on a condition. Fields which is responsible for grouping are known assets. For example โ€“ students having grades of more than 70%.
