重命名子表后 DolphinDB 无法写入流

Question

代码如下并执行

share streamTable(10000:0,`timestamp`temperature, [TIMESTAMP,DOUBLE]) as pubTable
share streamTable(10000:0,`ts`temp, [TIMESTAMP,DOUBLE]) as subTable1
share streamTable(10000:0,`ts`temp, [TIMESTAMP,DOUBLE]) as subTable2
topic1 = subscribeTable(, "pubTable", "actionName1", -1, subTable1, true)
topic1 = subscribeTable(, "pubTable", "actionName2", -1, myhandler, true)
vtimestamp = 1..10  
vtemp = 2.0 2.2 2.3 2.4 2.5 2.6 2.7 0.13 0.23 2.9
tableInsert(pubTable,vtimestamp,vtemp)

然后执行下面的代码

share streamTable(10000:0,`ts`temp, [TIMESTAMP,DOUBLE]) as subTable1
share streamTable(10000:0,`ts`temp, [TIMESTAMP,DOUBLE]) as subTable2
tableInsert(pubTable,vtimestamp,vtemp)

发现没有写入数据

为什么？

Answer 1

share streamTable(10000:0,`ts`temp, [TIMESTAMP,DOUBLE]) as subTable1
share streamTable(10000:0,`ts`temp, [TIMESTAMP,DOUBLE]) as subTable2

上面的代码重新定义了这两个表：subTable1和subTables。所以这两个订阅者找不到原来的表。
