Generér fra kode

Kopiér de færdige kodeeksempler på denne side og indsæt dem i letdraws Generate from Code-værktøj for at producere et diagram på sekunder. Værktøjet auto-detekterer formatet; for detaljer, se siden Generér fra kode.

Sådan bruger du det: åbn More tools (⋯) -> Generate from Code i den nederste værktøjslinje, kopiér kodeblokken fra et af eksemplerne nedenfor, indsæt den, og tryk på Add. Det lille skema over hvert eksempel er en forhåndsvisning af den struktur, koden producerer; når du kopierer, skal du kun kopiere kodeblokken under det.

Alle eksemplerne er bygget op omkring det samme e-handels (shopping)-scenarie.

SQL (PostgreSQL-skema)

Forvandler CREATE TABLE-sætninger og deres foreign key-relationer til et ER (entity-relationship)-diagram.

Den struktur, denne kode producerer:

Customers

         └─< OrderDetails >─ Products >─ Categories

( ─<  one-to-many relationship (1 → N) ;  >─  foreign key (N → 1) )
