Expand description

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)§

This struct is marked as 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.
§select: Select

The select clause of the query

§from: From

The from clause of the query

§distinct: Distinct

The distinct clause of the query

§where_clause: Where

The where clause of the query

§order: Order

The order clause of the query

§limit_offset: LimitOffset

The combined limit/offset clause of the query

§group_by: GroupBy

The group by clause of the query

§having: Having

The having clause of the query

§locking: Locking

The locking clause of the query
