Struct SelectStatement

#[non_exhaustive]
pub struct SelectStatement<From, Select = DefaultSelectClause<From>, Distinct = NoDistinctClause, Where = NoWhereClause, Order = NoOrderClause, LimitOffset = LimitOffsetClause<NoLimitClause, NoOffsetClause>, GroupBy = NoGroupByClause, Having = NoHavingClause, Locking = NoLockingClause> {
    pub select: Select,
    pub from: From,
    pub distinct: Distinct,

}

Available on crate feature i-implement-a-third-party-backend-and-opt-into-breaking-changes only.

This type represents a select query

Using this type directly is only meaningful for custom backends that need to provide a custom QueryFragment implementation

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

from: From

The from clause of the query

distinct: Distinct

where_clause: Where
