  1. why need rename test.array -> test.array_table ? Because Array standard a data type in newer H2. So H2 throws:
An exception or error caused a run to abort: Syntax error in SQL statement "CREATE TABLE TEST.ARRAY[*] (AR INTEGER ARRAY) AS SELECT ARRAY[1, 2, 3]"; expected "identifier"; SQL statement:
CREATE TABLE test.array (ar Integer ARRAY) AS SELECT ARRAY[1, 2, 3] [42001-202]
  1. Why need add INTEGER ? Because ARRAY need identify data type in newer H2. otherwise:
An exception or error caused a run to abort: Syntax error in SQL statement "CREATE TABLE TEST.ARRAY_TABLE (AR ARRAY[*]) AS SELECT ARRAY[1, 2, 3]"; expected "IDENTITY, data type"; SQL statement:
CREATE TABLE test.array_table (ar ARRAY) AS SELECT ARRAY[1, 2, 3] [42001-202]
  1. Why need change '(1, 2, 3)' to ARRAY[1, 2, 3]? Because cannot convert it to ARRAY in newer H2.
An exception or error caused a run to abort: Data conversion error converting "'(1, 2, 3)' (ARRAY_TABLE: ""AR"" INTEGER ARRAY)"; SQL statement:
CREATE TABLE test.array_table (ar Integer ARRAY) AS SELECT '(1, 2, 3)' [22018-202]

The data type is CHAR(20). ref: https://github.com/apache/spark/blob/0819210f7a88a77efb20e8c786ba01b30f2b9b05/sql/core/src/test/scala/org/apache/spark/sql/jdbc/JDBCSuite.scala#L149
It seems the newer H2 append the other space.

Yes, new result is correct. It's nice to have this update.

H2 older version will throws:

org.h2.jdbc.JdbcSQLException: Column "_ROWID_" not found; SQL statement:
CREATE FORCE VIEW PUBLIC._0 AS
SELECT
    _ROWID_
FROM TEST.PEOPLE [42122-195]

But, it OK in newer version.

Can you look into the commit history and see the original purpose of adding this test?

OK seems properties.setProperty("rowId", "false") doesn't work for h2 2.0 anymore. I think we can remove this test now, as well as properties.setProperty("rowId", "false") in the test setup.
