pub enum OwnedDbConn {
    Sqlx(PoolConnection<Any>),
    SeaOrm(DatabaseConnection),
    Diesel(DieselBlockingPool),
}

An acquired handle, decoupled from the pool’s lifetime so it can be held across .await points and moved into transactions.

impl OwnedDbConn

pub async fn execute(&mut self, sql: &str) -> Result<u64, DataError>

Execute a statement (INSERT/UPDATE/DELETE/DDL); returns affected rows.

pub async fn execute_bind( &mut self, sql: &str, binds: &[&str], ) -> Result<u64, DataError>

Execute a parameterized statement; returns affected rows. Placeholder syntax follows the backend (? sqlite/mysql, $1… pg).

pub async fn fetch_one_i64(&mut self, sql: &str) -> Result<i64, DataError>

Fetch a single scalar i64 (e.g. SELECT COUNT(*) …).

pub async fn fetch_one_i64_bind( &mut self, sql: &str, binds: &[&str], ) -> Result<i64, DataError>

Fetch a single scalar i64 with positional binds.

pub async fn fetch_one_string( &mut self, sql: &str, binds: &[&str], ) -> Result<String, DataError>

Fetch a single scalar string with positional binds.
