Struct UnpivotStatement 

pub struct UnpivotStatement {
    pub source: Box<TableFactor>,
    pub on: Vec<Expr>,
    pub into: Option<UnpivotInto>,
}

DuckDB statement-form UNPIVOT: UNPIVOT <source> ON <expr>[, …] [INTO NAME <ident> VALUE <ident>[, …]]

The query counterpart to TableFactor::Unpivot; see PivotStatement. https://duckdb.org/docs/stable/sql/statements/unpivot.

Fields

source: Box<TableFactor>

The relation being unpivoted (table name, table function, or subquery).

on: Vec<Expr>

ON — the columns collapsed into name/value rows.

into: Option<UnpivotInto>

INTO NAME … VALUE … — the name/value output columns. None uses DuckDB’s defaults (name/value).
