Create Sink to Clickhouse table

[reidlai]

Describe the bug

I tried to create a sink pointing to Cllickhouse table with ReplacingMergeTree but seems cannot see the table.

E.g. I create the table xxx using clickhouse client

(base) ➜ ~ clickhouse client --host localhost --port 9000 --user clickhouse --password
ClickHouse client version 24.7.3.42 (official build).
Password for user (clickhouse):
Connecting to localhost:9000 as user clickhouse.
Handling connection for 9000
Connected to ClickHouse server version 24.8.4.

ClickHouse client version is older than ClickHouse server. It may lack support for new features.

Warnings:

• Delay accounting is not enabled, OSIOWaitMicroseconds will not be gathered. You can enable it using echo 1 > /proc/sys/kernel/task_delayacct or by using sysctl.

)

SETTINGS index_granularity = 8192

1 row in set. Elapsed: 0.002 sec.

Then I tried to create sink as below:

) ;

, Error: Failed to run the query

hi
can you run
select distinct database,name from system.tables where name = 'organization_geolocationhierarchy'
in your clickhouse

[reidlai]

xxx.xxx.svc.cluster.local :) select distinct database,name from system.tables where name = 'organization_geolocationhierarchy'

SELECT DISTINCT
database,
name
FROM system.tables
WHERE name = 'organization_geolocationhierarchy'

Query id: f1873292-dccf-4fb2-830b-60c9b24d7c6c

Ok.

0 rows in set. Elapsed: 0.003 sec.

[reidlai]

after i move the table to another database , the query can show:

:) SELECT DISTINCT
database,
name
FROM system.tables
WHERE name = 'organization_geolocationhierarchy'

SELECT DISTINCT
database,
name
FROM system.tables
WHERE name = 'organization_geolocationhierarchy'

Query id: fffa00a9-6fa1-4372-851a-76029591a49c

┌─database─┬─name──────────────────────────────┐

1. │ <db_name_was_hided> │ organization_geolocationhierarchy │
   └──────────┴───────────────────────────────────┘

1 row in set. Elapsed: 0.003 sec.

But Risingwave still cannot see the table

Hi, could you make sure your sink info is ok, the problem is because rw is running this query and not getting the data.
I'll try it with your version as well, may be a setup item error or compatibility issue

[xxhZs]

Hello, testing your version works fine. Can you check if the databases and tables in your rw sink are the same as the ones found in the ck?
