All replies. Combines the results of two or more queries into a single result set that includes all the rows that belong to all queries in the union. The UNION operation is different from using joins that combine columns from two tables. The following are basic rules for combining the result sets of two queries by using UNION:. Left outer join produces a complete set of records from Table A, with the matching records (where available) in Table B. If there is no match, the right side will contain null. SELECT * FROM TableA LEFT OUTER JOIN TableB ON TableA.name = TableB.name WHERE TableB.id IS null. id name id name. 2 Monkey null null. The mutating joins add columns from y to x, matching rows based on the keys: inner_join (): includes all rows in x and y. left_join (): includes all rows in x. right_join (): includes all rows in y. full_join (): includes all rows in x or y. If a row in x matches multiple rows in y, all the rows in y will be returned once for each matching row. Inner joins mean getting the common fields or entries of multiple database tables into a single table. However, Outer join focuses on the dissimilar as well as common data from tables.
