Final Answer:
To correctly insert "Oshkosh Bgosh" into the Supplier table, the following SQL statement should be used:
```sql
INSERT INTO Supplier (CompanyName, ContactName, CountryId) VALUES ('Oshkosh Bgosh', 'YourContactName', YourCountryId);
```
Step-by-step explanation:
The SQL `INSERT` statement is used to add new records to a table. In this case, the Supplier table has columns CompanyName, ContactName, and CountryId. To insert "Oshkosh Bgosh," we need to provide values for these columns.
The SQL query specifies the columns (CompanyName, ContactName, CountryId) and their corresponding values. Replace 'YourContactName' and YourCountryId with the actual contact name and country ID for Oshkosh Bgosh. For example:
```sql
INSERT INTO Supplier (CompanyName, ContactName, CountryId) VALUES ('Oshkosh Bgosh', 'John Doe', 1);
```
This query inserts a new record with the CompanyName set to 'Oshkosh Bgosh', ContactName set to 'John Doe', and CountryId set to 1. Adjust the ContactName and CountryId values based on your specific data.
It's important to note that you should replace 'YourContactName' and YourCountryId with the actual values you want to insert into the Supplier table, ensuring that the CountryId value corresponds to a valid entry in the Country table since CountryId is a foreign key referencing the CountryId column in the Country table.
