Given the above data for a recipe database, how many records would be included in the result set for the following query?
SELECT RecipeName, IngredientName FROM Recipe CROSS JOIN Ingredient;
a) 8
b) 6
c) 4
d) 2

Answer 1

The result set of a CROSS JOIN between the provided ingredients list and recipes cannot be determined precisely without the number of recipes. However, for each recipe, there would be 4 results, one for each ingredient.

Step-by-step explanation:

The question refers to performing a CROSS JOIN operation in a database containing recipes and ingredients. A CROSS JOIN combines all rows from the first table with all rows from the second table, resulting in every possible combination of rows between the two tables. Considering there are 4 ingredient records, if we assume there is at least 1 recipe, the result of the CROSS JOIN would include a record for every combination of the recipe(s) with each ingredient.

Without the exact number of recipes, the answer cannot be determined precisely from the given data. However, if we assume there is only one recipe in the Recipe table, the query would return 4 records (1 recipe × 4 ingredients). For multiple recipes, this number would be multiplied by the number of recipes.
