mysqldump exports only one table

try this. There are in general three ways to use mysqldump—

in order to dump a set of one or more tables,

shell> mysqldump [options] db_name [tbl_name ...]

a set of one or more complete databases

shell> mysqldump [options] --databases db_name ...

or an entire MySQL server—as shown here:

shell> mysqldump [options] --all-databases

• Exporting the Table

To export the table run the following command from the command line:

mysqldump -p --user=username dbname tableName > tableName.sql

This will export the tableName to the file tableName.sql.

• Importing the Table

To import the table run the following command from the command line:

mysql -u username -p -D dbname < tableName.sql

The path to the tableName.sql needs to be prepended with the absolute path to that file. At this point the table will be imported into the DB.
