Answer 1

You can concatenate the bind variable with the wildcard % characters:

EXECUTE IMMEDIATE
  'SELECT COUNT(*) FROM ' || t.owner || '.' || t.table_name ||
  ' WHERE '||t.column_name||' LIKE ''%'' || :1 || ''%'''
  INTO match_count
  USING 'ALERT';

Note that the single quotes have to be escaped by doubling them up.

Change it to

EXECUTE IMMEDIATE
  'SELECT COUNT(*) FROM ' || t.owner || '.' || t.table_name ||
  ' WHERE '||t.column_name||' like :1'
  INTO match_count
  USING '%ALERT%';
