Struct sqlx_models_parser::ast::Case

pub struct Case {
    pub operand: Option<Box<Expr>>,
    pub conditions: Vec<Expr>,
    pub results: Vec<Expr>,
    pub else_result: Option<Box<Expr>>,
}

CASE [<operand>] WHEN <condition> THEN <result> ... [ELSE <result>] END

Note we only recognize a complete single expression as <condition>, not < 0 nor 1, 2, 3 as allowed in a <simple when clause> per https://jakewheat.github.io/sql-overview/sql-2011-foundation-grammar.html#simple-when-clause

Fields

operand: Option<Box<Expr>>

conditions: Vec<Expr>

results: Vec<Expr>

else_result: Option<Box<Expr>>
