python-mysqlHow can I join two tables in MySQL using Python?

Joining two tables in MySQL using Python can be done using the JOIN command in a SELECT statement. The syntax for joining two tables is as follows:

SELECT table1.column1, table2.column2
FROM table1
JOIN table2
ON table1.column1 = table2.column2;

This statement will return all rows from both tables where the column1 of table1 matches the column2 of table2.

For example, if table1 is a table of student IDs and table2 is a table of student grades, the following statement can be used to join the two tables:

SELECT table1.student_id, table2.grade
FROM table1
JOIN table2
ON table1.student_id = table2.student_id;

## Output example

student_id  grade
1   A
2   B
3   C
4   D

Code explanation

• SELECT table1.column1, table2.column2: This part of the statement is used to specify which columns should be returned by the statement. In this example, column1 from table1 and column2 from table2 are specified.
• FROM table1: This part of the statement is used to specify which table should be used as the primary source of data. In this example, table1 is specified.
• JOIN table2: This part of the statement is used to specify which table should be joined to the primary table. In this example, table2 is specified.
• ON table1.column1 = table2.column2: This part of the statement is used to specify the condition that should be used to join the two tables. In this example, column1 of table1 is compared to column2 of table2.
