</>

pub fn epilog(select slct: Select, epilog eplg: String) -> Select

Appends an Epilog to the Select query.

fragment

</>

pub fn fragment(fragment frgmt: Fragment) -> SelectValue

Creates a SelectFragment off a Fragment.

from_query

  sub_query sb_qry: ReadQuery,
  alias als: String,

Gets the Comment from the Select query.

get_epilog

</>

pub fn get_epilog(select slct: Select) -> Epilog

Gets the Epilog from the Select query.

get_from

</>

pub fn get_from(select slct: Select) -> From

Gets the FROM clause of the Select query.

get_having

</>

pub fn get_having(select slct: Select) -> Where

GetsHAVING in the Select query.

See function having on details why this returns a Where.

get_order_by

</>

pub fn get_order_by(select slct: Select) -> OrderBy

Gets the OrderBy from the Select query.

get_select

</>

pub fn get_select(select slct: Select) -> Selects

Gets the SelectValues of the Select query.

group_by

</>

pub fn group_by(
  select slct: Select,
  group_by grpb: String,
) -> Select

Sets or appends GroupBy a single into an existing GroupBy.
