The type of join that is used to combine complete data from multiple tables is called an Outer Join.

Here's a step-by-step explanation:

1. An Inner Join returns only the rows from both tables where there is a match based on the specified condition. If there is no match, the result is NULL on either side.

2. A Left Join returns all the rows from the left table, and the matched rows from the right table. If there is no match, the result is NULL on the right side.

3. A Right Join returns all the rows from the right table, and the matched rows from the left table. If there is no match, the result is NULL on the left side.

4. An Outer Join, however, returns all rows from both tables, regardless of whether there is a match or not. If there is no match, the result is NULL on either side. This is why it's used to combine complete data from multiple tables.

The type of join that is used to combine complete data from multiple tables is called an Inner Join.

Here's a step-by-step explanation:

1. An Inner Join is a type of join in SQL (Structured Query Language) that is used to combine rows from two or more tables based on a related column between them.

2. It creates a new result table by combining column values of two tables (table1 and table2) based upon the join-predicate. The query compares each row of table1 with each row of table2 to find all pairs of rows which satisfy the join-predicate.

3. When the join-predicate is satisfied, column values for each matched pair of rows of table1 and table2 are combined into a result row.

4. The result of the Inner Join includes only the rows from both tables where there is a match based on the specified condition. If there is no match, the result is NULL.

5. Therefore, an Inner Join returns only the rows where there is a match in both tables. It does not return the rows from the left table (table1) if there is no match in the right table (table2), and vice versa.

6. This is why it is said that an Inner Join is used to combine complete data from multiple tables.
