DB: MySQL Workbench

Exporting DDL

Within MySQL Workbench, go to

Server > Data Export

and select the schema of interest:

I generally prefer to select the checkbox which states "Skip Table Data (no-data)".

This will dump the DDL only to a series of *.sql files:

Importing DDL

Open MySQL Workbench, and go to Data Import/Restore:

Importing DDL (terminal session)

Assumption: I have a schema named soundex, and a username/password with identical values.

This simple python script creates a table for each alpha character:

import string

f = open('tables.ddl','w')

f.write("use soundex;")
for letter in string.ascii_lowercase:  
 f.write("CREATE TABLE tb" + letter + " ( id SMALLINT NOT NULL AUTO_INCREMENT, PRIMARY KEY(id), k varchar(256) not null, v varchar(256) not null );\n")
f.close()

I run this script using

$ python generate-ddl.py

And the output looks like this:

CREATE TABLE tba ( id SMALLINT NOT NULL AUTO_INCREMENT, PRIMARY KEY(id), k varchar(256) not null, v varchar(256) not null );
CREATE TABLE tbb ( id SMALLINT NOT NULL AUTO_INCREMENT, PRIMARY KEY(id), k varchar(256) not null, v varchar(256) not null );
CREATE TABLE tbc ( id SMALLINT NOT NULL AUTO_INCREMENT, PRIMARY KEY(id), k varchar(256) not null, v varchar(256) not null );
CREATE TABLE tbd ( id SMALLINT NOT NULL AUTO_INCREMENT, PRIMARY KEY(id), k varchar(256) not null, v varchar(256) not null );
CREATE TABLE tbe ( id SMALLINT NOT NULL AUTO_INCREMENT, PRIMARY KEY(id), k varchar(256) not null, v varchar(256) not null );
CREATE TABLE tbf ( id SMALLINT NOT NULL AUTO_INCREMENT, PRIMARY KEY(id), k varchar(256) not null, v varchar(256) not null );
CREATE TABLE tbg ( id SMALLINT NOT NULL AUTO_INCREMENT, PRIMARY KEY(id), k varchar(256) not null, v varchar(256) not null );
CREATE TABLE tbh ( id SMALLINT NOT NULL AUTO_INCREMENT, PRIMARY KEY(id), k varchar(256) not null, v varchar(256) not null );
CREATE TABLE tbi ( id SMALLINT NOT NULL AUTO_INCREMENT, PRIMARY KEY(id), k varchar(256) not null, v varchar(256) not null );
CREATE TABLE tbj ( id SMALLINT NOT NULL AUTO_INCREMENT, PRIMARY KEY(id), k varchar(256) not null, v varchar(256) not null );
CREATE TABLE tbk ( id SMALLINT NOT NULL AUTO_INCREMENT, PRIMARY KEY(id), k varchar(256) not null, v varchar(256) not null );
CREATE TABLE tbl ( id SMALLINT NOT NULL AUTO_INCREMENT, PRIMARY KEY(id), k varchar(256) not null, v varchar(256) not null );
CREATE TABLE tbm ( id SMALLINT NOT NULL AUTO_INCREMENT, PRIMARY KEY(id), k varchar(256) not null, v varchar(256) not null );
CREATE TABLE tbn ( id SMALLINT NOT NULL AUTO_INCREMENT, PRIMARY KEY(id), k varchar(256) not null, v varchar(256) not null );
CREATE TABLE tbo ( id SMALLINT NOT NULL AUTO_INCREMENT, PRIMARY KEY(id), k varchar(256) not null, v varchar(256) not null );
CREATE TABLE tbp ( id SMALLINT NOT NULL AUTO_INCREMENT, PRIMARY KEY(id), k varchar(256) not null, v varchar(256) not null );
CREATE TABLE tbq ( id SMALLINT NOT NULL AUTO_INCREMENT, PRIMARY KEY(id), k varchar(256) not null, v varchar(256) not null );
CREATE TABLE tbr ( id SMALLINT NOT NULL AUTO_INCREMENT, PRIMARY KEY(id), k varchar(256) not null, v varchar(256) not null );
CREATE TABLE tbs ( id SMALLINT NOT NULL AUTO_INCREMENT, PRIMARY KEY(id), k varchar(256) not null, v varchar(256) not null );
CREATE TABLE tbt ( id SMALLINT NOT NULL AUTO_INCREMENT, PRIMARY KEY(id), k varchar(256) not null, v varchar(256) not null );
CREATE TABLE tbu ( id SMALLINT NOT NULL AUTO_INCREMENT, PRIMARY KEY(id), k varchar(256) not null, v varchar(256) not null );
CREATE TABLE tbv ( id SMALLINT NOT NULL AUTO_INCREMENT, PRIMARY KEY(id), k varchar(256) not null, v varchar(256) not null );
CREATE TABLE tbw ( id SMALLINT NOT NULL AUTO_INCREMENT, PRIMARY KEY(id), k varchar(256) not null, v varchar(256) not null );
CREATE TABLE tbx ( id SMALLINT NOT NULL AUTO_INCREMENT, PRIMARY KEY(id), k varchar(256) not null, v varchar(256) not null );
CREATE TABLE tby ( id SMALLINT NOT NULL AUTO_INCREMENT, PRIMARY KEY(id), k varchar(256) not null, v varchar(256) not null );
CREATE TABLE tbz ( id SMALLINT NOT NULL AUTO_INCREMENT, PRIMARY KEY(id), k varchar(256) not null, v varchar(256) not null );

And I can import this into MySQL using this command:

mysql -u soundex -psoundex -hlocalhost < tables.ddl

Within MySQL I can verify that this worked successfully:

$ mysql -u soundex -psoundex -hlocalhost
