Struct WhereNode 

pub struct WhereNode {
    pub childs: Vec<NodeType>,
}

Represents a where node in py_sql. It’s used to dynamically build the WHERE clause of a SQL query. It will automatically prepend WHERE if needed and remove leading AND or OR keywords from its content.

Example

PySQL syntax:

SELECT * FROM table
where:
  if id != null:
    AND id = #{id}
  if name != null:
    AND name = #{name}

This would result in SELECT * FROM table WHERE id = #{id} AND name = #{name} (if both conditions are true), or SELECT * FROM table WHERE id = #{id} (if only id is not null), or SELECT * FROM table WHERE name = #{name} (if only name is not null). If no conditions are met, the WHERE clause is omitted entirely.

Fields

childs: Vec<NodeType>

Trait Implementations

impl Clone for WhereNode

fn clone(&self) -> WhereNode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WhereNode

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

Formats the value using the given formatter.

impl Name for WhereNode

fn name() -> &'static str

impl PartialEq for WhereNode

fn eq(&self, other: &WhereNode) -> 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 ToHtml for WhereNode

fn as_html(&self) -> String

impl Eq for WhereNode
