Module diesel::query_builder
source · [−]Expand description
Contains traits responsible for the actual construction of SQL statements
The types in this module are part of Diesel’s public API, but are generally only useful for implementing Diesel plugins. Applications should generally not need to care about the types inside of this module.
Modules
Types related to managing bind parameters during query construction.
Structs
The primary type used when walking a Diesel AST during query execution.
i-implement-a-third-party-backend-and-opt-into-breaking-changesThis type represents a batch insert clause, which allows to insert multiple rows at once.
i-implement-a-third-party-backend-and-opt-into-breaking-changesA boxed variant of LimitOffsetClause
A struct that implements fmt::Display and fmt::Debug to show the SQL
representation of a query.
Represents a SQL DELETE statement.
The structure returned by insert_into.
A fully constructed insert statement.
i-implement-a-third-party-backend-and-opt-into-breaking-changesA query node representing a limit clause
i-implement-a-third-party-backend-and-opt-into-breaking-changesA helper query node that contains both limit and offset clauses
i-implement-a-third-party-backend-and-opt-into-breaking-changesThis type represents a not existing from clause
i-implement-a-third-party-backend-and-opt-into-breaking-changesA query node indicating the absence of a limit clause
i-implement-a-third-party-backend-and-opt-into-breaking-changesA query node indicating the absence of an offset clause
i-implement-a-third-party-backend-and-opt-into-breaking-changesA query node representing an offset clause
Represents a query with an ONLY clause.
i-implement-a-third-party-backend-and-opt-into-breaking-changesThis type represents a SQL Returning clause
The return value of sql_query.
Represents a complete UPDATE statement.
i-implement-a-third-party-backend-and-opt-into-breaking-changesThis type represents a values clause used as part of insert statements
Traits
Types which can be passed to
update.set.
Types that can be converted into a complete, typed SQL query.
A type which manages serializing bind parameters during query construction.
Interface to add information to conflict targets. Designed to be open for further additions to conflict targets like constraints
A trait used to construct type erased boxed variant of the current query node
A complete SQL query with a return type.
Constructs a SQL query from a Diesel AST.
An untyped fragment of SQL.
Uniquely identifies queries by their type for the purpose of prepared statement caching.
i-implement-a-third-party-backend-and-opt-into-breaking-changesSpecialised variant of Expression for select clause types
Indicates that a type is a SELECT statement.
i-implement-a-third-party-backend-and-opt-into-breaking-changesMarker trait to indicate that no additional operations have been added to a record for insert.
Functions
Takes a query QueryFragment expression as an argument and returns a type
that implements fmt::Display and fmt::Debug to show the query.
Type Definitions
A DELETE statement with a boxed WHERE clause
An UPDATE statement with a boxed WHERE clause.
A specialized Result type used with the query builder.
Represents the return type of diesel::insert_or_ignore_into
Represents the return type of diesel::replace_into
Represents a complete INSERT OR IGNORE statement.
Represents a complete INSERT OR REPLACE statement.
