LAST模式下需要设置两个sortcolumn列
create table dfs://jq.trade_days(trade_day DATETIME [comment="交易日期"]), sortColumns=["trade_day"], keepDuplicates=LAST => Usage: createTable(dbHandle, table, tableName, [compressMethods], [sortColumns], [keepDuplicates=ALL]). Can't use duplicate policy LAST or FIRST when the number of sort keys is less than 2.
请问创建表格时,这个报错是什么意思呢
