source§impl D1PreparedStatement
impl D1PreparedStatement
sourcepub fn bind(self, values: &[JsValue]) -> Result<Self>
pub fn bind(self, values: &[JsValue]) -> Result<Self>
Bind one or more parameters to the statement. Consumes the old statement and returns a new statement with the bound parameters.
D1 follows the SQLite convention for prepared statements parameter binding.
§Considerations
Supports Ordered (?NNNN) and Anonymous (?) parameters - named parameters are currently not supported.
sourcepub fn bind_refs<'a, T: IntoIterator<Item = &'a U>, U: D1Argument + 'a>(
&self,
values: T,
) -> Result<Self>
pub fn bind_refs<'a, T: IntoIterator<Item = &'a U>, U: D1Argument + 'a>( &self, values: T, ) -> Result<Self>
Bind one or more parameters to the statement. Returns a new statement with the bound parameters, leaving the old statement available for reuse.
sourcepub fn batch_bind<'a, U: IntoIterator<Item = &'a V> + 'a, T: IntoIterator<Item = U> + 'a, V: D1Argument + 'a>(
&self,
values: T,
) -> Result<Vec<Self>>
pub fn batch_bind<'a, U: IntoIterator<Item = &'a V> + 'a, T: IntoIterator<Item = U> + 'a, V: D1Argument + 'a>( &self, values: T, ) -> Result<Vec<Self>>
Bind a batch of parameter values, returning a batch of prepared statements.
Result can be passed to D1Database::batch to execute the statements.
sourcepub async fn first<T>(&self, col_name: Option<&str>) -> Result<Option<T>>where
T: for<'a> Deserialize<'a>,
pub async fn first<T>(&self, col_name: Option<&str>) -> Result<Option<T>>where
T: for<'a> Deserialize<'a>,
Return the first row of results.
If col_name is Some, returns that single value, otherwise returns the entire object.
If the query returns no rows, then this will return None.
If the query returns rows, but column does not exist, then this will return an Err.
sourcepub async fn run(&self) -> Result<D1Result>
pub async fn run(&self) -> Result<D1Result>
Executes a query against the database but only return metadata.
sourcepub async fn all(&self) -> Result<D1Result>
pub async fn all(&self) -> Result<D1Result>
Executes a query against the database and returns all rows and metadata.
sourcepub async fn raw<T>(&self) -> Result<Vec<Vec<T>>>where
T: for<'a> Deserialize<'a>,
pub async fn raw<T>(&self) -> Result<Vec<Vec<T>>>where
T: for<'a> Deserialize<'a>,
Executes a query against the database and returns a Vec of rows instead of objects.
sourcepub async fn raw_js_value(&self) -> Result<Vec<JsValue>>
pub async fn raw_js_value(&self) -> Result<Vec<JsValue>>
Executes a query against the database and returns a Vec of JsValues.
sourcepub fn inner(&self) -> &D1PreparedStatementSys
pub fn inner(&self) -> &D1PreparedStatementSys
Returns the inner JsValue bindings object.
