pub struct Statement {
    pub sql: String,
    pub values: Option<Values>,
    pub db_backend: DatabaseBackend,
}

Defines an SQL statement

Fields

sql: String

The SQL query

values: Option<Values>

The values for the SQL statement’s parameters

db_backend: DatabaseBackend

The database backend this statement is constructed for. The SQL dialect and values should be valid for the DbBackend.

Implementations

impl Statement

pub fn from_string<T>(db_backend: DatabaseBackend, stmt: T) -> Statement

where T: Into<String>,

Create a Statement from a crate::DatabaseBackend and a raw SQL statement

pub fn from_sql_and_values<I, T>( db_backend: DatabaseBackend, sql: T, values: I, ) -> Statement

where I: IntoIterator<Item = Value>, T: Into<String>,

Create a SQL statement from a crate::DatabaseBackend, a raw SQL statement and param values

Trait Implementations

impl Clone for Statement

fn clone(&self) -> Statement

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Statement

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Display for Statement

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for Statement

fn eq(&self, other: &Statement) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
