Struct tiberius::ExecuteResult

pub struct ExecuteResult { /* fields omitted */ }

A Stream of counts of affected rows resulting from an INSERT, UPDATE or DELETE query. The ExecuteResult needs to be polled empty before sending another query to the Client, failing to do so causes a flush before the next query, slowing it down in an undeterministic way.

If executing multiple queries, the resulting counts will be come separately, marking the rows affected for each query.

let stream = conn
    .execute(
        "INSERT INTO #Test (id) VALUES (@P1); INSERT INTO #Test (id) VALUES (@P2, @P3)",
        &[&1i32, &2i32, &3i32],
    )
    .await?;

let result: Vec<u64> = stream.into_iter().collect();
assert_eq!(vec![1, 2], result);

Implementations

impl<'a> ExecuteResult

pub fn total(self) -> u64

Aggregates all resulting row counts into a sum.

let rows_affected = conn
    .execute(
        "INSERT INTO #Test (id) VALUES (@P1); INSERT INTO #Test (id) VALUES (@P2, @P3)",
        &[&1i32, &2i32, &3i32],
    )
    .await?;

assert_eq!(3, rows_affected.total());
