JsonConstructorExpr: a SQL/JSON constructor.

Fields

kind: JsonCtorKind

args: Vec<Expr>

func: Option<Expr>

The expression that gives the value of JSON_OBJECTAGG, JSON_ARRAYAGG and JSON_ARRAY with a subquery.

format: JsonFormat

The FORMAT clause of the subquery of JSON_ARRAY.

returning: JsonReturning

The RETURNING clause, or the type that the analyzer gives when the call has no clause.

unique: bool

WITH UNIQUE KEYS.

absent_on_null: bool
