MySQL INTERSECT Operator
INTERSECT operator is used in MySQL to retrieve records from two or more SELECT statements only where these records are in common. It executes table union and presents only the row that appears in all SELECT statements of the queries. It summarizes information to help find the common points that are accurate and not altered in several data sets.
Syntax:
The syntax for using INTERSECT in MySQL is as follows:
SELECT column1, column2, ...
FROM table1
INTERSECT
SELECT column1, column2, ...
FROM table2;
Here, table1 and table2 denote the tables where data is selected and column1, column2, … refer to the columns which are used. While INTERSECT ensures that only the rows that are in both SELECTs are added to the result set, OUTER JOIN contains all the rows from the first SELECT and ONLY the rows corresponding to the rows in the second SELECT.
