🗂️ Support Export Database to SQL Server
We're excited to share that Export DBML Schema to SQL Server is now supported !
Now you can quickly design and visualize your database schema and export to SQL Server.

We heard you! dbdiagram.io now supports auto-increment!
Our DBML sample code:
Table users {
id integer [pk, increment]
name varchar [not null]
}
When in PostgreSQL:
CREATE TABLE "users" (
"id" SERIAL PRIMARY KEY,
"name" varchar NOT NULL
)
When in MySQL:
CREATE TABLE `users`
(
`id` integer PRIMARY KEY AUTO_INCREMENT,
`name` varchar(255) NOT NULL
)

Hi dbdiagram.io users, it's been a great journey with you! To have a better focus on our engagement, we are proud to announce: We have moved our forum from Holistics forum to the new site at https://community.dbdiagram.io/!
New categories will be created and we hope this will allow you to quickly obtain answers for all your queries 😉
Index with single field (with index name):
CREATE INDEX Date on users (created_at)
Index with multiple fields (composite index):
CREATE INDEX on users (created_at, country)
Index with an expression:
CREATE INDEX ON users (lower(name))
(bonus) Composite index with expression:
CREATE INDEX ON users ( country, (lower(name)) )
Indexes {
created_at [name: "Date"]
(created_at, country)
`lower(name)`
(country,`lower(name)`)
(country) [unique]
booking_date [type: btree]
}
type
: type of index (btree, gin, gist, hash depending on DB), we only accept type Btree and Hash for now.name
: name of indexunique
: unique indexUsers can define single or multi-column indexes. Example 2 shows a multi-column index.
Table products {
id int [pk]
name varchar
merchant_id int [not null]
price int
status varchar
created_at datetime [default: `now()`]
Indexes {
(merchant_id, status) [name:"product_status"]
id [unique]
}
}

dbdiagram.io now allows default value to your columns! For example, when creating BOOLEAN columns, we commonly give the column a default value (TRUE or FALSE, whatever is appropriate) and make the column NOT NULL. This means, if no other value is given, you can be confident that the column will have a set appropriate value.
default: 123
or default: 123.456
default: 'some string value'
default: `now() - interval '5 days'`
default: false
Table users {
id integer [primary key]
username varchar(255) [not null, unique]
full_name varchar(255) [not null]
gender varchar(1) [default: 'm']
created_at timestamp [default: `now()`]
rating integer [default: 10]
}
Enum job_status {
created
running
done
failure
}
Table jobs {
id integer
status job_status [note: 'Status of a job', default: 'created']
}
