[jira] [Created] (FLINK-21494) Could not execute statement 'USE
`default`' in Flink SQL client
Zheng Hu created FLINK-21494:
--------------------------------
Summary: Could not execute statement 'USE `default`' in Flink SQL client
Key: FLINK-21494
URL: https://issues.apache.org/jira/browse/FLINK-21494
Project: Flink
Issue Type: Bug
Components: Table SQL / Client
Affects Versions: 1.12.1
Reporter: Zheng Hu
Fix For: 1.12.2, 1.13.0
I have two databases in my iceberg catalog, one is `default`, another one is `test_db`. While I cannot switch to use the `default` database because of the Flink SQL parser bug:
{code}
Flink SQL> show databases;
default
test_db
Flink SQL> use `default`;
[ERROR] Could not execute SQL statement. Reason:
org.apache.flink.sql.parser.impl.ParseException: Incorrect syntax near the keyword 'USE' at line 1, column 1.

It's OK to switch to use `test_db`.

Flink SQL> use `test_db`;
Flink SQL> show tables;
[INFO] Result was empty.
