Enum JsonTableColumn

pub enum JsonTableColumn {
    Named(JsonTableNamedColumn),
    ForOrdinality(Ident),
    Nested(JsonTableNestedColumn),
}

Expand description

A single column definition in MySQL’s JSON_TABLE table valued function.

See

SELECT *
FROM JSON_TABLE(
    '["a", "b"]',
    '$[*]' COLUMNS (
        name FOR ORDINALITY,
        value VARCHAR(20) PATH '$',
        NESTED PATH '$[*]' COLUMNS (
            value VARCHAR(20) PATH '$'
        )
    )
) AS jt;

Variants§

Named(JsonTableNamedColumn)

A named column with a JSON path

ForOrdinality(Ident)

The FOR ORDINALITY column, which is a special column that returns the index of the current row in a JSON array.

Nested(JsonTableNestedColumn)

A set of nested columns, which extracts data from a nested JSON array.
