Function currentStatement

backend/plugin/parser/tidb/completion.go:549–556

currentStatement returns the statement containing byte position pos within statement, along with pos translated to an offset within that statement. It uses omni's splitter so completion sees only the caret's statement, not table references from earlier statements in the buffer.
