Intersect Operator in MariaDB

Examples of Intersect Operator in MariaDB

The Intersect operator is an operator that is used to retrieve the common records from two or more tables. It works by comparing the result sets of two or more queries and returning only the rows that appear in all result sets. It makes the intersect a useful operator for finding common elements between datasets.

Syntax:

The syntax for using the Intersect operator in MariaDB is straightforward:

SELECT col1, col2, ... FROM table1 INTERSECT SELECT col1, col2, ... FROM table2;

Explanation:

SELECT column1, column2, … specifies the columns you want to retrieve from the tables.
FROM table1 specifies the first table or query whose result set you want to compare.
INTERSECT is the Intersect operator.
SELECT column1, column2, … specifies the columns you want to retrieve from the second table or query.
FROM table2 specifies the second table or query.

It’s important to note that the number of columns and their data types in the SELECT queries must match for the Intersect operator to work correctly.
