Timo Walther created FLINK-4270:
-----------------------------------
Summary: 'as' in front of join does not work
Key: FLINK-4270
URL: https://issues.apache.org/jira/browse/FLINK-4270
Project: Flink
Issue Type: Bug
Components: Table API & SQL
Reporter: Timo Walther
The following example passes the validation but fails during toRexNode phase:
{code}
val customers = getCustomerDataSet(env).toTable(tEnv)
.as('id, 'mktSegment)
val orders = getOrdersDataSet(env).toTable(tEnv)
.as('orderId, 'custId, 'orderDate, 'shipPrio)
val items =
orders.join(customers)
.where('custId === 'id)
items.printOnTaskManager("ok")
{code}
Leads to
{code}
Exception in thread "main" java.lang.IllegalArgumentException: field [custId]
not found; input fields are: [id, mktSegment, id0, mktSegment0]
