Struct FuncLastInsertId 

pub struct FuncLastInsertId;

The LAST_INSERT_ID() function expression (MySQL-specific).

Returns the first automatically generated value that was set for an AUTO_INCREMENT column by the most recent INSERT statement. This is primarily used to retrieve auto-increment IDs after insertion on MySQL, which doesn’t support RETURNING clauses.

Behavior

• Returns the first auto-increment ID from the most recent INSERT
• When multiple rows are inserted, returns the ID of the first row
• Subsequent row IDs can be calculated by adding row offsets (first_id + 1, first_id + 2, etc.)
• Returns 0 if no AUTO_INCREMENT value was generated

Trait Implementations

impl Clone for FuncLastInsertId

fn clone(&self) -> FuncLastInsertId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FuncLastInsertId

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

Formats the value using the given formatter.

impl Default for FuncLastInsertId

fn default() -> FuncLastInsertId

Returns the “default value” for a type.

impl From<FuncLastInsertId> for Expr

fn from(value: FuncLastInsertId) -> Expr

Converts to this type from the input type.

impl From<FuncLastInsertId> for ExprFunc

fn from(value: FuncLastInsertId) -> ExprFunc

Converts to this type from the input type.

impl PartialEq for FuncLastInsertId

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