2,614 PointsFOREIGN KEY CONSTRAINT IN SQL LITE
To add foreign key constraint in SQL Lite do you add REFERENCE table name (ID)?
Now recreate the MEMBERS table with the new FAVORITE_ROCK_ID column, and make sure it has a foreign key constraint to the ID column of the ROCKS table. The columns should now be: ID, FIRST_NAME, LAST_NAME, and FAVORITE_ROCK_ID.
CREATE TABLE MEMBERS ( ID INT PRIMARY KEY, FRIST_NAME VARCHAR(255), LAST_NAME VARCHAR(255), FAVORITE_ROCK_ID REFERENCE ROCKS(ID) );
BUMMER; Don't forget to add a foreign key constraint to the FAVORITE_ROCK_ID column.

- "FRIST_NAME" instead of "FIRST_NAME"
- "REFERENCE" instead of "REFERENCES"
