What is the SQL equivalent of VLOOKUP?

As an experienced tutor registered on UrbanPro.com, specializing in Microsoft Excel Training & Coaching, let's explore the SQL equivalent of VLOOKUP and understand how this knowledge can enhance your data retrieval skills.

**1. Understanding VLOOKUP in Excel:

Overview:

• VLOOKUP is a powerful function in Excel used for vertical data lookup.

Key Features:

• Searches for a specific value in the first column of a table.
• Retrieves related information from the same row in a specified column.

**2. Introducing SQL JOINs:

Overview:

• In SQL, the equivalent of VLOOKUP is achieved through the use of JOIN operations.

Key Features:

• JOINs combine rows from two or more tables based on related columns.
• Different types of JOINs, such as INNER JOIN, LEFT JOIN, and RIGHT JOIN, provide flexibility.

**3. Main SQL JOIN Types:

INNER JOIN:

• Retrieves rows from both tables where there is a match between the specified columns.

  sql

• SELECT * FROM table1 INNER JOIN table2 ON table1.column = table2.column;

LEFT JOIN (Equivalent of VLOOKUP):

• Retrieves all rows from the left table and the matched rows from the right table.

  sql

• SELECT * FROM table1 LEFT JOIN table2 ON table1.column = table2.column;

RIGHT JOIN:

• Retrieves all rows from the right table and the matched rows from the left table.

  sql

• SELECT * FROM table1 RIGHT JOIN table2 ON table1.column = table2.column;

FULL JOIN:

• Retrieves all rows when there is a match in either the left or the right table.

  sql

• SELECT * FROM table1 FULL JOIN table2 ON table1.column = table2.column;

**4. Choosing the Right JOIN Type:

Considerations:

• INNER JOIN:

  • Suitable when you only want matching rows from both tables.

• LEFT JOIN:

  • Similar to VLOOKUP, retrieves all rows from the left table and matched rows from the right table.

• RIGHT JOIN:

  • Retrieves all rows from the right table and matched rows from the left table.

• FULL JOIN:

  • Retrieves all rows when there is a match in either the left or the right table.

**5. Transitioning from VLOOKUP to SQL JOINs:

Guidance:

• Understand the key columns linking the tables (equivalent to the VLOOKUP criteria).
• Identify the desired information to be retrieved from both tables.
