MySQLInsertValue

Enum MySQLInsertValue 

Source
pub enum MySQLInsertValue<'a, V: SQLParam, T> {
    Omit,
    Null,
    Value(ValueWrapper<'a, V, T>),
}
Expand description

One field of a generated insert model: left out, NULL, or a value.

You rarely build this directly. The with_* setters and new on a generated InsertX model convert their arguments into it.

Variants§

§

Omit

Leave the column out of the INSERT so the database default applies.

§

Null

Insert SQL NULL.

§

Value(ValueWrapper<'a, V, T>)

Insert a value, placeholder, or typed SQL expression.
