Then follow the instructions.
The sql file scholardb-schema.sql
contains the database schema and sample data. To create the database, run the following command:
mysql -u root -p < scholardb-schema.sql
or in MySQL:
source scholardb-schema.sql
The sql file scholardb-data.sql
contains sample data. To populate the database, run the following command:
mysql -u root -p < scholardb-data.sql
or in MySQL:
source scholardb-data.sql
To use foreign key constraints in SQLite, run the following command:
PRAGMA foreign_keys = ON;
- The sql file

- The sql file
scholardb-data.sql
contains sample data. To populate the database, run the following command:
sqlite3 scholardb.db < scholardb-data.sql
or in SQLite:
.read scholardb-data.sql
