Module query_builder

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.

Re-exports

• pub use self::bind_collector::BindCollector;

Modules

• bind_collector
  Types related to managing bind parameters during query construction.

Structs

• AstPass
  The primary type used when walking a Diesel AST during query execution.
• DebugQuery
  A struct that implements fmt::Display and fmt::Debug to show the SQL representation of a query.
• DeleteStatement
  Represents a SQL DELETE statement.
• IncompleteInsertStatement
  The structure returned by insert_into.
• InsertStatement
  A fully constructed insert statement.
• SqlQuery
  The return value of sql_query.
• UpdateStatement
  Represents a complete UPDATE statement.
• UpdateTarget
• ValuesClause

Traits

• AsChangeset
  Types which can be passed to update.set.
• AsQuery
  Types that can be converted into a complete, typed SQL query.
• IntoUpdateTarget
  A type which can be passed to update or delete.
• Query
  A complete SQL query with a return type.
• QueryBuilder
  Constructs a SQL query from a Diesel AST.
• QueryFragment
  An untyped fragment of SQL.
• QueryId
  Uniquely identifies queries by their type for the purpose of prepared statement caching.
• SelectQuery
  Indicates that a type is a SELECT statement.
• UndecoratedInsertRecord
  Marker trait to indicate that no additional operations have been added to a record for insert.

Functions

• debug_query
  Takes a query QueryFragment expression as an argument and returns a type that implements fmt::Display and fmt::Debug to show the query.

Type Aliases

• BoxedDeleteStatement
  A DELETE statement with a boxed WHERE clause
• BoxedUpdateStatement
  An UPDATE statement with a boxed WHERE clause.
• BuildQueryResult
  A specialized Result type used with the query builder.
• IncompleteUpdateStatementDeprecated
  The type returned by update. The only thing you can do with this type is call set on it.
