ViewOptions

Struct ViewOptions 

Source
pub struct ViewOptions {
    pub algorithm: Option<ViewAlgorithm>,
    pub definer: Option<Box<Definer>>,
    pub sql_security: Option<SqlSecurityContext>,
}
Expand description

The MySQL view definition-option prefix [ALGORITHM = …] [DEFINER = …] [SQL SECURITY …], shared verbatim by CreateView and AlterView — the two statements name the same options in the same fixed source order, immediately before the VIEW keyword.

Each option is independently optional; the source order (algorithm, then definer, then SQL security) is engine-required — a permutation (DEFINER before ALGORITHM, SQL SECURITY before either) is ER_PARSE_ERROR. All-None is the ordinary view with no prefix (every non-MySQL dialect, and a bare MySQL CREATE/ALTER VIEW). The Definer reuses the shared routine/event account reference; the SqlSecurityContext reuses the routine security tag. This is a non-spanned bundle — Definer carries its own span, and the two Copy tags ride the owning statement’s span, so the prefix needs no meta of its own.

Fields§

§algorithm: Option<ViewAlgorithm>

The optional ALGORITHM = … processing algorithm; None when omitted.

§definer: Option<Box<Definer>>

The optional DEFINER = <user> account; None when omitted. Boxed like the routine definer (a rare fat field paying only a null pointer when absent).

§sql_security: Option<SqlSecurityContext>

The optional SQL SECURITY { DEFINER | INVOKER } privilege context; None when omitted.
