Final answer:
A Cartesian join between a table with 5 records and another with 10 records results in 50 records, as each row from the first table joins with each from the second.
Step-by-step explanation:
The student has asked how many rows are returned in a Cartesian join between one table having 5 records and a second table having 10 records. A Cartesian join, also known as a cross join, results in a Cartesian product of the two tables. This means each row from the first table is joined with each row from the second table.
To calculate the number of rows returned, you multiply the number of rows in the first table by the number of rows in the second table. In this case, 5 records from the first table multiplied by 10 records from the second table equals 50 records in the resulting Cartesian join. Therefore, the join would return a total of 50 rows.
A Cartesian join, also known as a cross join, is a type of join in database management systems that combines every row from one table with every row from another table. In this case, we have one table with 5 records and a second table with 10 records. To find the number of rows returned in the Cartesian join between these two tables, we need to multiply the number of records in each table.
Therefore, the number of rows returned in the Cartesian join would be 5 * 10 = 50 rows.
