func (*RangerContext) Detach

func (r *RangerContext) Detach(staticExprCtx exprctx.BuildContext) *RangerContext

Detach detaches this context from the session context.

NOTE: Though this session context can be used parallelly with this context after calling it, the `StatementContext` cannot. The session context should create a new `StatementContext` before executing another statement.
