Struct Returning 

pub struct Returning {
    pub columns: Vec<ReturningColumn>,
    pub operation: ReturnOperation,
}

RETURNING clause specification.

Fields

columns: Vec<ReturningColumn>

Columns to return.

operation: ReturnOperation

Operation type (for MSSQL OUTPUT).

Implementations

impl Returning

pub fn all(operation: ReturnOperation) -> Self

Create RETURNING all columns.

pub fn columns<I, S>(operation: ReturnOperation, columns: I) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

Create RETURNING specific columns.

pub fn to_postgres_sql(&self) -> String

Generate PostgreSQL RETURNING clause.

pub fn to_sqlite_sql(&self) -> String

Generate SQLite RETURNING clause.

pub fn to_mssql_sql(&self) -> String

Generate MSSQL OUTPUT clause.

pub fn to_sql(&self, db_type: DatabaseType) -> QueryResult<String>

Generate SQL for database type.

Trait Implementations

impl Clone for Returning

fn clone(&self) -> Returning

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Returning

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Returning

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Returning

fn eq(&self, other: &Returning) -> 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.

impl Serialize for Returning

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Returning
