Struct SelectQuery 

pub struct SelectQuery {
    pub table_name: String,
    pub table_alias: Option<String>,
    pub joins: Vec<JoinClause>,
    pub projection: Projection,
    pub selection: Option<Expr>,
    pub order_by: Option<OrderByClause>,
    pub limit: Option<usize>,
    pub distinct: bool,
    pub group_by: Vec<String>,
}

A parsed, simplified SELECT query.

Fields

table_name: String

table_alias: Option<String>

Optional AS alias on the leading FROM table. The executor’s scope resolver treats alias.unwrap_or(table_name) as the qualifier name.

joins: Vec<JoinClause>

SQLR-5 — JOIN clauses in source order. Empty = single-table SELECT, the existing fast path.

projection: Projection

selection: Option<Expr>

Raw sqlparser WHERE expression, evaluated by the executor at run time.

order_by: Option<OrderByClause>

limit: Option<usize>

distinct: bool

SELECT DISTINCT.

group_by: Vec<String>

GROUP BY a, b — bare column names. Empty = no GROUP BY.
