When I type the above in Shell, it produces the following.

I hope you notice there is a table "testTB" and 2 records in the quote above.

I like to restore the database "testDB" above.

So I made a database "testDB" like the following.
mysql> create database testDB

And I did the following.
$ mysqldump -u root -p testDB < testDB1.sql
Enter password:
As I enter the password correctly.
It says the following.

But there is not a table "testTB" and its 2 records in the just above.

How can I restore a table "testTB" and its 2 records?

you export it on "testDB.sql "
but you import "testDB1.sql "

?
you can check the testDB1.sql first
 
$ mysqldump -u root -p testDB < testDB1.sql

This is not the proper was to restore a DB. "mysqldump" commands prints a dump file. You are trying to feed it with the content of the testDB1.sql file, but this command doesnt care about what you type at all. See http://www.tldp.org/LDP/abs/html/io-redirection.html for explanations.

Use the following command to restore the DB from the file :
Code:
$ mysql -u root -p testDB < testDB1.sql
