Struct PgPrepared 

pub struct PgPrepared { /* private fields */ }

Obtain via oxisql_core::Connection::prepare on a crate::PgConnection.

The statement is compiled once by the server and re-used for every subsequent execution, avoiding repeated parse/plan cycles.

Trait Implementations

impl PreparedStatement for PgPrepared

fn execute<'life0, 'life1, 'life2, 'async_trait>( &'life0 mut self, params: &'life1 [&'life2 dyn ToSqlValue], ) -> Pin<Box<dyn Future<Output = Result<u64, OxiSqlError>> + Send + 'async_trait>>

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

Execute the prepared statement (DML/DDL) and return the row count.

fn query<'life0, 'life1, 'life2, 'async_trait>( &'life0 mut self, params: &'life1 [&'life2 dyn ToSqlValue], ) -> Pin<Box<dyn Future<Output = Result<Vec<Row>, OxiSqlError>> + Send + 'async_trait>>

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

Execute the prepared statement as a SELECT and return all rows.

fn sql(&self) -> &str

Return the original SQL text this statement was compiled from.
