What values for Countryld do the suppliers Sugarplum and Periwinkle have after the UPDATE statement executes

The Correct Answer and Explanation is :

Without access to the specific UPDATE statement and the initial data in the Supplier table, it’s challenging to determine the exact CountryId values for the suppliers ‘Sugarplum’ and ‘Periwinkle’ after the UPDATE statement executes. The outcome depends on the conditions specified in the UPDATE statement and the initial CountryId values for these suppliers.

In SQL, the UPDATE statement is used to modify existing records in a table. The general syntax is:

UPDATE table_name
SET column1 = value1, column2 = value2, ...
WHERE condition;

The WHERE clause specifies which records should be updated. If the WHERE clause matches the records for ‘Sugarplum’ and ‘Periwinkle’, their CountryId values will be updated accordingly. If there’s no WHERE clause, all records in the table will be updated.

For example, consider the following UPDATE statement:

UPDATE Supplier
SET CountryId = 2
WHERE CountryId = 1;

This statement updates the CountryId to 2 for all suppliers whose current CountryId is 1. If ‘Sugarplum’ and ‘Periwinkle’ initially had a CountryId of 1, their CountryId would be updated to 2. If their initial CountryId was not 1, they would remain unchanged.

Therefore, to determine the exact CountryId values for ‘Sugarplum’ and ‘Periwinkle’ after the UPDATE statement executes, we need to know:

1. The specific UPDATE statement executed.
2. The initial CountryId values for ‘Sugarplum’ and ‘Periwinkle’.

Without this information, it’s not possible to provide a definitive answer.
