Struct diesel::query_builder::BatchInsert

pub struct BatchInsert<V, Tab, QId, const STABLE_QUERY_ID: bool> {
    pub values: V,
    /* private fields */
}

This type represents a batch insert clause, which allows to insert multiple rows at once.

Custom backends can specialize the QueryFragment implementation via SqlDialect::BatchInsertSupport or provide fully custom ExecuteDsl and LoadQuery implementations

Fields

values: V

List of values that should be inserted

impl<V: Debug, Tab: Debug, QId: Debug, const STABLE_QUERY_ID: bool> Debug for BatchInsert<V, Tab, QId, STABLE_QUERY_ID>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<Tab, DB, V, QId, const HAS_STATIC_QUERY_ID: bool> QueryFragment<DB> for BatchInsert<V, Tab, QId, HAS_STATIC_QUERY_ID>

where DB: Backend, Self: QueryFragment<DB, DB::BatchInsertSupport>,

fn walk_ast<'b>(&'b self, pass: AstPass<'_, 'b, DB>) -> QueryResult<()>

Walk over this QueryFragment for all passes.

fn to_sql(&self, out: &mut DB::QueryBuilder, backend: &DB) -> QueryResult<()>

Converts this QueryFragment to its SQL representation.

Serializes all bind parameters in this query.

fn is_safe_to_cache_prepared(&self, backend: &DB) -> QueryResult<bool>

Is this query safe to store in the prepared statement cache?

fn is_noop(&self, backend: &DB) -> QueryResult<bool>

Does walking this AST have any effect?

impl<Tab, DB, V, QId, const HAS_STATIC_QUERY_ID: bool> QueryFragment<DB, PostgresLikeBatchInsertSupport> for BatchInsert<Vec<ValuesClause<V, Tab>>, Tab, QId, HAS_STATIC_QUERY_ID>

where DB: Backend + SqlDialect<BatchInsertSupport = PostgresLikeBatchInsertSupport>, DB::InsertWithDefaultKeyword: SupportsDefaultKeyword, ValuesClause<V, Tab>: QueryFragment<DB>, V: QueryFragment<DB>,

impl<V, QId: 'static, Tab: 'static, const STABLE_QUERY_ID: bool> QueryId for BatchInsert<V, Tab, QId, STABLE_QUERY_ID>

type QueryId = QId

A type which uniquely represents Self in a SQL query.

const HAS_STATIC_QUERY_ID: bool = STABLE_QUERY_ID

Can the SQL generated by Self be uniquely identified by its type?

fn query_id() -> Option<TypeId>

Returns the type id of Self::QueryId if Self::HAS_STATIC_QUERY_ID. Returns None otherwise.
