DistSQLContext provides all information needed by using functions in `distsql`
func (*DistSQLContext) AppendWarning ¶
func (dctx *DistSQLContext) AppendWarning(warn error)
AppendWarning appends the warning to the warning handler.
func (*DistSQLContext) Detach ¶
func (dctx *DistSQLContext) Detach() *DistSQLContext
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.
