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:

CREATE TABLE entity1 (

col1 INTEGER,

col2 VARCHAR(20),

...

);

Primary keys are converted as follow:

CREATE TABLE entity1 (

pk1 INTEGER,

pk2 VARCHAR(10),

...

PRIMARY KEY (pk1, pk2, ...)

);

Not-nullable columns are converted as follow:

CREATE TABLE entity1 (

col1 VARCHAR(20) NOT NULL,

...

);

Unique columns are converted as follow:

CREATE TABLE entity1 (

...

UNIQUE (col1, col2, ...)

);

Foreign keys are converted as follow:

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.

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)

SET FOREIGN_KEY_CHECKS = 0;
