Struct View

pub struct View { /* private fields */ }

Represents an entire View, which may be Part of a wider Schema or used standalone. Can be converted into an SQL Statement via the SQLStatement Methods. It is an Error for the name to be empty (Error::EmptyViewName) or the Select to be empty (Error::EmptyViewSelect).

Implementations

impl View

pub fn new( name: String, temp: bool, columns: Vec<ViewColumn>, select: String, ) -> Self

pub fn new_default(name: String, select: String) -> Self

pub fn add_column(self, column: ViewColumn) -> Self

pub fn set_name(self, name: String) -> Self

pub fn set_temp(self, temp: bool) -> Self

pub fn set_select(self, select: String) -> Self

Trait Implementations

impl Clone for View

fn clone(&self) -> View

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for View

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

Formats the value using the given formatter.

impl PartialEq for View

fn eq(&self, other: &Self) -> 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 SQLStatement for View

fn len(&mut self, transaction: bool, if_exists: bool) -> Result<usize>

Calculates the exact length of the statement as it is currently configured. Any change to the configuration invalidates previously calculated lengths. Parameters are the same as in SQLStatement::build.

fn build(&mut self, transaction: bool, if_exists: bool) -> Result<String>

Builds the SQL Statement as a String.
