Module diesel::query_builder [−] [src]

Contains traits responsible for the actual construction of SQL statements

Reexports

pub use self::bind_collector::BindCollector;

IncompleteInsertStatement	The structure returned by `insert`. The only thing that can be done with it is call `into`.
IncompleteUpdateStatement	The type returned by `update`. The only thing you can do with this type is call `set` on it.
UpdateStatement

AsChangeset	Types which can be passed to `update.set`.
AsQuery	Types that can be converted into a complete, typed SQL query. This is used internally to automatically add the right select clause when none is specified, or to automatically add `RETURNING *` in certain contexts
Changeset	Apps should not need to concern themselves with this trait.
IntoUpdateTarget
Query	A complete SQL query with a return type. This can be a select statement, or a command such as `update` or `insert` with a `RETURNING` clause. Unlike `Expression`, types implementing this trait are guaranteed to be executable on their own.
QueryBuilder	Apps should not need to concern themselves with this trait.
QueryFragment	An untyped fragment of SQL. This may be a complete SQL command (such as an update statement without a `RETURNING` clause), or a subsection (such as our internal types used to represent a `WHERE` clause). All methods on `Connection` that execute a query require this trait to be implemented.
