Enum LoadDataFieldOrVar 

pub enum LoadDataFieldOrVar {
    Column {
        name: Ident,
        meta: Meta,
    },
    Variable {
        name: Ident,
        meta: Meta,
    },
}

One entry of a LoadDataStatement target list (mysql sql_yacc.yy field_or_var): a destination column name, or a user variable (@name) that captures the raw field value for use in the SET clause. A spanned enum so each spelling round-trips its own form and a column is never confused with a variable.

Variants

Column

A destination column (simple_ident_nospvar).

Fields

name: Ident

The column name.

meta: Meta

Source location and node identity.

Variable

A user variable (@name) capturing the field’s raw value; the name is held without the @ sigil, its quote style preserved for round-trip.

Fields

name: Ident

The user-variable name (without the @ sigil).

meta: Meta

Source location and node identity.
