-----------------------------------
hi, [~jark] the exception is like this, I tracked the code and found that it
seems to be a calcite parsing error
{code:java}
Flink SQL> create database `mod`;
[INFO] Database has been created.
Flink SQL> show databases;
db
default
iceberg_db
mod
Flink SQL> use `mod`;
[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.
Was expecting one of:
"ABS" ...
"ALTER" ...
"ARRAY" ...
"AVG" ...
"CALL" ...
"CARDINALITY" ...
"CASE" ...
{code}
> can not use `use` command to switch database
