Identifying Overlapping Data: Extracting Common Records from Tables Without Using JOINs

 

To select common records from two tables without using joins, you can use the INTERSECT operator in SQL. The INTERSECT operator returns rows that are common to both tables. Here's the basic syntax:

SELECT column1, column2, ...

FROM table1

INTERSECT

SELECT column1, column2, ...

FROM table2;

This query will return the common records that exist in both table1 and table2. If a row appears in both tables, it will be included in the result set.

Keep in mind that the INTERSECT operator works with columns of the same data type and in the same order in both SELECT statements.
