The MINUS function in Oracle database is used to subtract all rows that appear in the second query results from the first query results, returning only unique rows in the result set. Use cases for the MINUS function include:<\/p>\n

    \n
  1. To find the differences between two tables, you can use the MINUS function to search for rows that exist in the first table but not in the second table.<\/li>\n
  2. To find rows that do not meet a certain condition, you can use the MINUS function to subtract rows that meet the condition from the first query result.<\/li>\n
  3. To find the difference between two query results: You can use the MINUS function to find the rows that exist in the first query result but not in the second.<\/li>\n
