Required Methods§

Source

fn execute_batch<'life0, 'life1, 'async_trait>( &'life0 mut self, query: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<(), SqlMiddlewareDbError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Executes a batch of SQL queries (can be a mix of reads/writes) within a transaction. No parameters are supported.

Source

fn execute_select<'life0, 'life1, 'life2, 'async_trait>( &'life0 mut self, query: &'life1 str, params: &'life2 [RowValues], ) -> Pin<Box<dyn Future<Output = Result<ResultSet, SqlMiddlewareDbError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Executes a single SELECT statement and returns the result set.

Source

fn execute_dml<'life0, 'life1, 'life2, 'async_trait>( &'life0 mut self, query: &'life1 str, params: &'life2 [RowValues], ) -> Pin<Box<dyn Future<Output = Result<usize, SqlMiddlewareDbError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Executes a single DML statement (INSERT, UPDATE, DELETE, etc.) and returns the number of rows affected.
