我如何加入两个不同的表，例如
all_order_ask:([]ask:();ask_qty:();exchange_name_ask:())
all_order_bid:([]bid:();bid_qty:();exchange_name_bid:())
并得到 =====>
final_order:ask:();ask_qty:();exchange_name_ask:();bid:();bid_qty:();exchange_name_bid:()
两个表的行数相同
您可以使用 uj： https: //code.kx.com/q/ref/uj/
all_order_ask uj all_order_bid
ask ask_qty exchange_name_ask bid bid_qty exchange_name_bid

q)
如果您的表格看起来类似如下：
all_order_ask
ask ask_qty exchange_name_ask
