where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Query the database with the given SQL statement and parameters, returning a Result of SendableRecordBatchStream.

fn execute<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, sql: &'life1 str, params: &'life2 [&'static (dyn ToSql + Sync)], ) -> Pin<Box<dyn Future<Output = Result<u64, GenericError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Execute the given SQL statement with parameters, returning the number of affected rows.

impl DbConnection<Connection, &'static (dyn ToSql + Sync)> for SqliteConnection

fn as_any(&self) -> &dyn Any

fn as_any_mut(&mut self) -> &mut dyn Any

fn as_async( &self, ) -> Option<&dyn AsyncDbConnection<Connection, &'static (dyn ToSql + Sync)>>

impl SchemaValidator for SqliteConnection

type Error = Error

Available on crate features sqlite or duckdb or postgres only.

fn is_data_type_supported(data_type: &DataType) -> bool

Available on crate features sqlite or duckdb or postgres only.

fn unsupported_type_error(data_type: &DataType, field_name: &str) -> Self::Error

Available on crate features sqlite or duckdb or postgres only.

fn is_field_supported(field: &Arc<Field>) -> bool

Available on crate features sqlite or duckdb or postgres only.

fn is_schema_supported(schema: &SchemaRef) -> bool

Available on crate features sqlite or duckdb or postgres only.

fn handle_unsupported_schema( schema: &SchemaRef, unsupported_type_action: UnsupportedTypeAction, ) -> Result<SchemaRef, Self::Error>

Available on crate features sqlite or duckdb or postgres only.

For a given input schema, rebuild it according to the UnsupportedTypeAction. Implemented for a specific connection type, that connection determines which types it supports. If the UnsupportedTypeAction is Error/String, the function will return an error if the schema contains an unsupported data type. If the UnsupportedTypeAction is Warn, the function will log a warning if the schema contains an unsupported data type and remove the column. If the UnsupportedTypeAction is Ignore, the function will remove the column silently.
