DDL Extension for StarUML
=========================
This extension for StarUML (http://staruml.io) support to generate DDL (Data Definition Language) from ERD. Install this extension from Extension Manager of StarUML.
How to use
----------
1. Click the menu (`Tools > DDL > Generate DDL...`)
2. Select a data model that will be generated to DDL.
3. Save the generated DDL to a file.
Generation rules
----------------
Belows are the rules to convert from ERD elements to DDL.
* All entities and columns are converted to create table statements as follow:
```sql
CREATE TABLE entity1 (
col1 INTEGER,
col2 VARCHAR(20),
...
);
```
* Primary keys are converted as follow:
```sql
CREATE TABLE entity1 (
pk1 INTEGER,
pk2 VARCHAR(10),
...
PRIMARY KEY (pk1, pk2, ...)
);
```
* Not-nullable columns are converted as follow:
```sql
CREATE TABLE entity1 (
col1 VARCHAR(20) NOT NULL,
...
);
```
* Unique columns are converted as follow:
```sql
CREATE TABLE entity1 (
...
UNIQUE (col1, col2, ...)
);
```
* Foreign keys are converted as follow:
```sql
CREATE TABLE entity1 (
fk1 INTEGER,
...
);
...
ALTER TABLE entity1 ADD FOREIGN KEY (fk1) REFERENCES entity2(col1);
```
* If `Quote Identifiers` option is selected, all identifiers will be surrounded by a backquote character.
```sql
CREATE TABLE `entity1` (
`col1` INTEGER,
`col2` VARCHAR(20),
...
);
```
* If `Drop Tables` option is selected, drop table statements will be included.
(__MySQL__ selected in `DBMS` option)
```sql
SET FOREIGN_KEY_CHECKS = 0;
DROP TABLE IF EXISTS entity1;
...
SET FOREIGN_KEY_CHECKS = 1;
CREATE TABLE entity1 (...);
...
```
(__Oracle__ selected in `DBMS` option)
```sql
DROP TABLE entity1 CASCADE CONSTRAINTS;`
...
CREATE TABLE entity1 (...);
...
```
