How to load data from another sql file into a main sql file? - MYSQL
POSSIBILITY #1
You need to check the table to see if it is damaged or corrupt
Please run the following:
USE bh576
SHOW TABLES LIKE 'AIRLINE';
SHOW CREATE TABLE AIRLINE \G

The first 2 Lines will verify the presence of AIRLINE.frm
The SHOW CREATE TABLE AIRLINE \G will reach out and attempt to retrieve AIRLINE.frm metadata. If this command complains by giving you that error
ERROR 1146 (42S02): Table 'bh576.AIRLINE' doesn't exist

Then, the table is broken in terms of its attachment to the InnoDB data dictionary.
If you get this to work in MySQL Workshop every time, then a corrupt table is not the problem.
POSSIBILITY #2
You need to make sure you are standing in a database.
It may be possible that the target database is not set in the dbcreate_f.sql script.
Before running the scripts, run this:
mysql&gt; SELECT database();

This should return the name of the database you are loading.
If this comes back as NULL just change to the target database before running
USE mydb
source dbcreate_f.sql
source dbload_f.sql
