Struct fields are mapped to Toql and database by default in a predictable way:

1. Table names are UpperCamelCase.
2. Column names are snake_case.
3. Toql fields are lowerCamelCase, dependend structs are separated with an underscore.

To adjust the default naming to an existing database scheme use the toql attributes tables and columns on the struct. Possible values are

• CamelCase
• snake_case
• SHOUTY_SNAKE_CASE
• mixedCase

# #![allow(unused_variables)]
#fn main() {
#[derive(Toql)]
#[toql(tables="SHOUTY_SNAKE_CASE", columns="UpperCase")]
  struct UserRef {
        user_id: u32
        full_name: String,
}
#}

is translated into

SELECT UserId, FullName FROM USER_REF;

Or use table an the struct and column on the fields.

# #![allow(unused_variables)]
#fn main() {
#[derive(Toql)]
#[toql(table="User")]
  struct UserRef {
    #[toql(column="id")]
        user_id: u32
        full_name: String,
}
#}

is translated into

SELECT id, full_name FROM User

Toql fields on a struct are always mixed case, while dependencies are separated with an unserscore.

# #![allow(unused_variables)]
#fn main() {
#[derive(Toql)]
#[toql(table="User")]
  struct UserRef {
    #[toql(column="id")]
        id: u32
        full_name: String,
        #[toql(self="counry_id", other="id")]
        county: Country
}
#}

is referred to as

id, fullName, country_id

To exclude fields from the query annotate it with skip.
