我希望能够只显示最低选项之一。例如'Andy Aardverk'购买'Avarice is Good'并且可以以更低的价格从'CARP'或'YRB Bronze'购买它。我只想要一个人展示它可能是'CARP'或'YRB Bronze'而不是两者。
我尝试在'名称，头衔，年份，价格，俱乐部，价格'上使用'group by'，但是出现了这个错误：
'SQL0119N An expression starting with "LOWEST_CLUB" specified in a SELECT
clause, HAVING clause, or ORDER BY clause is not specified in the GROUP BY
clause or it is in a SELECT clause, HAVING clause, or ORDER BY clause with a
column function and no GROUP BY clause is specified. SQLSTATE=42803'
