Question at position 12 What does the following SQL statement do? SELECT * From Customer WHERE Cust_Type = "Best"Selects all the fields from the Customer table for each row with a customer labeled "*" Selects all the fields from the Customer table for each row with a customer labeled "Best"Selects the "*" field from the Customer table for each row with a customer labeled "Best" Selects fields with a "*" in them from the Customer table

Question restatement: The query given is SELECT * FROM Customer WHERE Cust_Type = "Best". This means the database will return all columns for those rows in the Customer table where the Cust_Type column exactly equals Best.

Option 1: "Selects all the fields from the Customer table for each row with a customer labeled \"*\"". This would imply the label or value of * is being used to filter, which is not the case in the query. The WHERE clause uses Cust_Type = "Best", not a wildcard or * value, so this option incorrectly interprets both the label and the wildcard usage.

Option 2: "Selects all the fields from the Customer table for each row with a customer labeled \"Best\"". This aligns with the actual SQL: the asterisk means all columns are selected, the table is Customer, and the filter Cust_Type = "Best" selects only rows where the customer is labeled Best. This option correctly captures the two main components: selecting all fields and applying the Best filter.

Option 3: "Selects the \"*\" field from the Customer table for each row with a customer labeled \"Best\"". The query does not select a column named \"*\"; the asterisk is a shorthand for all columns in the result set, not a literal column name. Therefore this interpretation is incorrect.

Option 4: "Selects fields with a \"*\" in them from the Customer table". This suggests filtering based on asterisks appearing in field values or column names, which does not reflect the SQL syntax used here. The query does not search for fields containing asterisks; it selects all fields for rows meeting a type condition, so this is inaccurate.

Putting it together, the correct interpretation is that the query returns every column for rows in the Customer table where Cust_Type equals Best, rather than filtering by a literal star, selecting a column named star, or scanning for stars within field values. The evaluation of each option shows why the other three diverge from the actual semantics of SELECT * ... WHERE Cust_Type = "Best".
