ORM

Attributes

Structs

• [table: 'name'] sets a custom table name

Fields

• [primary] sets the field as the primary key
• [unique] sets the field as unique
• [unique: 'foo'] adds the field to a unique group
• [skip] field will be skipped
• [sql: type] sets the type which is used in sql (special type serial)
• [sql: 'name'] sets a custom column name for the field

Usage

struct Foo {
    id   int    [primary; sql: serial]
    name string [nonull]
}

Create

sql db {
    create table Foo
}

Drop

sql db {
    drop table Foo
}

Insert

var := Foo{
    name: 'abc'
}

sql db {
    insert var into Foo
}

Update

sql db {
    update Foo set name = 'cde' where name == 'abc'
}

Delete

sql db {
    delete from Foo where id > 10
}

Select

result := sql db {
    select from Foo where id == 1
}

result := sql db {
    select from Foo where id > 1 limit 5
}

result := sql db {
    select from Foo where id > 1 order by id
}
