        Verify the usage restrictions of each placeholder:

        1. Non-window triggers cannot use _twstart, _twend, _twduration, _twrownum.
        2. Non-sliding triggers cannot use _tcurrent_ts, _tprev_ts, _tnext_ts.
        3. Only timed triggers can use _tprev_localtime, _tnext_localtime.
        4. %%trows can only be used in the FROM clause.
        5. Other placeholders can only be used in the SELECT and WHERE clauses.
        6. The range of values for n in %%n.
        7. Misspelled placeholders.
        8. INSERT or other statements that do not return a result set are not allowed.
