Enum Query 

pub enum Query<D: Driver> {
    Raw(String),
    Prepared(D::Prepared),
}

Executable query: raw SQL or prepared statement.

Variants

Raw(String)

Unprepared SQL text.

Prepared(D::Prepared)

Driver prepared statement.

Implementations

impl<D: Driver> Query<D>

pub fn is_prepared(&self) -> bool

Returns true when this Query contains a backend-prepared statement.

pub fn clear_bindings(&mut self) -> Result<&mut Self>

Clear all bound values.

pub fn bind(&mut self, value: impl AsValue) -> Result<&mut Self>

Append a bound value. It results in an error if the query is not prepared.

pub fn bind_index( &mut self, value: impl AsValue, index: u64, ) -> Result<&mut Self>

Bind a value at a specific index. It results in an error if the query is not prepared.
