Python DolphinDB数据库中的连接表

用于连接表的DolphinDB函数是什么，例如Python中的concat（）？DolphinDB的SQL连接函数都是关于合并表，而不是连接表

请使用功能

unionAll

。这是一个例子

t1 = table( 1 2 3 as id, `IBM`MSFT`GOOG as sym)
t2 = table( 4 5 as id, `ORCA`C as sym)
unionAll(t1, t2)

如果需要连接多个表：

t1 = table( 1 2 3 as id, `IBM`MSFT`GOOG as sym)
t2 = table( 4 5 as id, `ORCA`C as sym)
t3 = table(6 7 as id, `BIDU`BABA as sym)
unionAll([t1, t2, t3], false)
