fn send<'e, 'q>(
&'e mut self,
command: &'q str
) -> Pin<Box<dyn Future<Output = Result<(), Error>> + 'e + Send>> where
'q: 'e,
&'e mut self,
command: &'q str
) -> Pin<Box<dyn Future<Output = Result<(), Error>> + 'e + Send>> where
'q: 'e,
Send a raw SQL command to the database.
This is intended for queries that cannot or should not be prepared (ex. BEGIN
).
Does not support fetching results.
fn execute<'e, 'q>(
&'e mut self,
query: &'q str,
args: <Self::Database as Database>::Arguments
) -> Pin<Box<dyn Future<Output = Result<u64, Error>> + 'e + Send>> where
'q: 'e,
&'e mut self,
query: &'q str,
args: <Self::Database as Database>::Arguments
) -> Pin<Box<dyn Future<Output = Result<u64, Error>> + 'e + Send>> where
'q: 'e,
Execute the query, returning the number of rows affected.
fn fetch<'e, 'q>(
&'e mut self,
query: &'q str,
args: <Self::Database as Database>::Arguments
) -> Pin<Box<dyn Stream<Item = Result<<Self::Database as Database>::Row, Error>> + 'e + Send>> where
'q: 'e,
&'e mut self,
query: &'q str,
args: <Self::Database as Database>::Arguments
) -> Pin<Box<dyn Stream<Item = Result<<Self::Database as Database>::Row, Error>> + 'e + Send>> where
'q: 'e,
Executes the query and returns a [Stream] of Row.
fn describe<'e, 'q>(
&'e mut self,
query: &'q str
) -> Pin<Box<dyn Future<Output = Result<Describe<Self::Database>, Error>> + 'e + Send>> where
'q: 'e,
&'e mut self,
query: &'q str
) -> Pin<Box<dyn Future<Output = Result<Describe<Self::Database>, Error>> + 'e + Send>> where
'q: 'e,
Analyze the SQL query and report the inferred bind parameter types and returned columns.
Provided methods
fn fetch_optional<'e, 'q>(
&'e mut self,
query: &'q str,
args: <Self::Database as Database>::Arguments
) -> Pin<Box<dyn Future<Output = Result<Option<<Self::Database as Database>::Row>, Error>> + 'e + Send>> where
'q: 'e,
&'e mut self,
query: &'q str,
args: <Self::Database as Database>::Arguments
) -> Pin<Box<dyn Future<Output = Result<Option<<Self::Database as Database>::Row>, Error>> + 'e + Send>> where
'q: 'e,
Executes the query and returns up to resulting record.
- crate::Error::FoundMoreThanOne will be returned if the query produced more than 1 row.
fn fetch_one<'e, 'q>(
&'e mut self,
query: &'q str,
args: <Self::Database as Database>::Arguments
) -> Pin<Box<dyn Future<Output = Result<<Self::Database as Database>::Row, Error>> + 'e + Send>> where
'q: 'e,
&'e mut self,
query: &'q str,
args: <Self::Database as Database>::Arguments
) -> Pin<Box<dyn Future<Output = Result<<Self::Database as Database>::Row, Error>> + 'e + Send>> where
'q: 'e,
Execute the query and return at most one resulting record.
