Preload static code blocks. To facilitate testing, a Druid connection pool is used in this example.
static {
Map<String, String> map = new HashMap<String, String>();
map.put("url", "jdbc:oceanbase://xxx.xxx.xxx.xxx:1521/");
map.put("driverClassName", "com.oceanbase.jdbc.Driver");
map.put("username", "a****");
map.put("password", "******");
try {
Class.forName(map.get("driverClassName"));
jdbcTemplate = new JdbcTemplate(DruidDataSourceFactory.createDataSource(map));
// These statements avoid errors. Without these two statements, errors may occur.
jdbcTemplate.execute("set transaction_isolation = 'READ-COMMITTED';");
jdbcTemplate.execute("set tx_isolation = 'READ-COMMITTED';");
} catch (Exception e) {
e.printStackTrace();
}
}@Test
public void createByOrcTypeDate(){

"CAR_SPEED NUMBER(3),"+
"CAP_DATE TIMESTAMP WITH LOCAL TIME ZONE," +
"DEV_CHNID VARCHAR2(50) not null," +
"TRSFMARK NUMBER(1) default 0," +
"CREATE_TIME DATE default sysdate" +

jdbcTemplate.execute(sql);
