Enum InstallStatement 

pub enum InstallStatement<X: Extension = NoExt> {
    Plugin {
        name: Ident,
        soname: Literal,
        meta: Meta,
    },
    Component {
        urns: ThinVec<Literal>,
        set: ThinVec<InstallComponentSetElement<X>>,
        meta: Meta,
    },
}

A MySQL INSTALL server-administration statement (gated by UtilitySyntax::plugin_component_statements) — one of the two forms of sql_yacc.yy install_stmt. The inverse UninstallStatement shares the same plugin_component_statements gate (an install/uninstall pair, like ATTACH/DETACH).

Generic over X because the COMPONENT form’s optional SET tail carries Exprs. MySQL grammar-accepts every well-formed shape but cannot prepare the COMPONENT forms over the binary protocol (ER_UNSUPPORTED_PS 1295) — a bind-time verdict the parse layer does not model; the PLUGIN form does prepare.

Variants

Plugin

INSTALL PLUGIN <name> SONAME <soname> — load a single plugin from a shared-library file. The name is a bare/back-quoted Ident (a quoted-string name is ER_PARSE_ERROR on mysql:8), the SONAME a required string Literal. Exactly one plugin — a comma list is rejected.

Fields

name: Ident

The plugin name (ident, not a quoted string).

soname: Literal

The SONAME shared-library file, a string literal.

meta: Meta

Source location and node identity.

Component

INSTALL COMPONENT <urn> [, <urn> …] [SET <var-assignment> [, …]] — load one or more components by URN, with an optional SET tail of scoped configuration-variable assignments. Each URN is a string Literal (TEXT_STRING_sys_list); the list is non-empty.

Fields

urns: ThinVec<Literal>

The component URNs, a non-empty list of string literals.

set: ThinVec<InstallComponentSetElement<X>>

The optional SET tail, empty when none was written; see InstallComponentSetElement.

meta: Meta

Source location and node identity.
