Answer:
False.
Step-by-step explanation:
An equi-join is a type of join in which the join condition is based on equality between values in the specified columns in the two tables being joined.
In an equi-join, duplicate columns are not eliminated in the result table. Instead, the result table will contain all the columns from both tables being joined, including any duplicate columns. To eliminate duplicate columns, you would need to explicitly specify which columns to include in the SELECT statement, or use a different type of join such as a natural join or inner join with USING clause.
