Struct Statement 

pub struct Statement<'c> { /* private fields */ }

A prepared statement; an SQL statement that SQLite has compiled and made ready to bind and execute.

Implementations

impl<'c> Statement<'c>

pub fn prepare( connection: &'c Connection, query: impl AsRef<str>, options: PrepareOptions, ) -> Result<Self, (ErrorMessage, Option<ErrorLocation>)>

Compile SQL query text into a prepared statement that SQLite can execute.

See PrepareOptions for the flags prepare understands. By default, SQLite will prepare the statement transiently, using limited memory that SQLite uses for short-lived operations (“lookaside allocator”). Use PrepareOptions::persistent() if the statement will be executed again over the program run.

pub fn binding(&mut self) -> Binding<'c, '_>

pub fn bind<'s, P>(&'s mut self, parameters: P) -> Result<Binding<'c, 's>>

where P: Parameters<'s>,

pub fn query<'s, P>(&'s mut self, parameters: P) -> Result<Execution<'c, 's>>

where P: Parameters<'s>,

pub fn execute<P>(&mut self, parameters: P) -> Result<isize>

where P: for<'a> Parameters<'a>,

pub fn insert<P>(&mut self, parameters: P) -> Result<Option<RowId>>

where P: for<'a> Parameters<'a>,

pub fn columns<'s>(&'s self) -> StatementColumns<'c, 's>

Inspect the columns returned by this statement.

pub fn parameters<'s>(&'s self) -> StatementParameters<'c, 's>

Inspect the parameters declared by this statement.

pub fn finalize(self) -> Result<(), ()>

Finalize (i.e., destroy) the prepared statement.
