---------------------------------
Component/s: Table SQL / Client
Affects Version/s: 1.10.0
Description:
When I was testing tpcds quries with sqlClient, but it reported the following
failure when one query was submitted repeatedly.
{code:java}
[ERROR] Could not execute SQL statement. Reason:
org.apache.flink.table.api.ValidationException: Table 'default: WITH
customer_total_return AS
( SELECT
sr_customer_sk AS ctr_customer_sk,
sr_store_sk AS ctr_store_sk,
sum(sr_return_amt) AS ctr_total_return
FROM store_returns, date_dim
WHERE sr_returned_date_sk = d_date_sk AND d_year = 2000
GROUP BY sr_customer_sk, sr_store_sk)
SELECT c_customer_id
FROM customer_total_return ctr1, store, customer
WHERE ctr1.ctr_total_return >
(SELECT avg(ctr_total_return) * 1.2
FROM customer_total_return ctr2
WHERE ctr1.ctr_store_sk = ctr2.ctr_store_sk)
AND s_store_sk = ctr1.ctr_store_sk
AND s_state = 'TN'
AND ctr1.ctr_customer_sk = c_customer_sk
ORDER BY c_customer_id
LIMIT 100' already exists. Please choose a different name.{code}
I checked the code, it seems that it will always create a new table and
registerTableSink, and caused the failure.
I think we can do some work here to fix it.
Summary: SqlClient throws exception 'Table already exists' when
