Struct InstallComponentSetElement 

pub struct InstallComponentSetElement<X: Extension = NoExt> {
    pub scope: Option<InstallComponentSetScope>,
    pub name: ObjectName,
    pub assignment: SetAssignment,
    pub value: InstallComponentSetValue<X>,
    pub meta: Meta,
}

One assignment in an INSTALL COMPONENT … SET tail (sql_yacc.yy install_set_value): [GLOBAL | PERSIST] <name> {= | :=} <value>. A strictly narrower grammar than the general MySQL SET — the scope is only the install_option_type set (GLOBAL/PERSIST, default GLOBAL; SESSION/LOCAL/PERSIST_ONLY and @/@@ sigils are ER_PARSE_ERROR on mysql:8), and the value is only install_set_rvalue (ON or an Expr; DEFAULT and the other SET sentinels reject). The name and assignment operator do reuse the general SET machinery (lvalue_variable, SetAssignment).

Fields

scope: Option<InstallComponentSetScope>

The scope keyword, or None for the implicit default (which MySQL treats as GLOBAL); see InstallComponentSetScope.

name: ObjectName

The variable name (lvalue_variable: a one- or two-part name[.name]).

assignment: SetAssignment

The = / := assignment operator (the two are synonyms).

value: InstallComponentSetValue<X>

The assigned value; see InstallComponentSetValue.

meta: Meta

Source location and node identity.
