Answer 1

An equijoin is typically an INNER JOIN which displays rows with matching values in a common column from two or more tables.

Step-by-step explanation:

The most common type of join which joins two or more tables together based upon the tables having equivalent data values in a common column is known as an equijoin. the correct answer to the question is b) INNER JOIN. An INNER JOIN is a type of equijoin where the result set includes all rows from both the participating tables where the key column's data matches. If the key data does not match then that combination of rows is not included in the result set. It is the default type of join in SQL if you don't specify the kind of join in your query.
