H2运行测试

测试代码：

@Test
public void test_h2_mem() throws SQLException
{
JdbcConnectionPool ds = JdbcConnectionPool.create("jdbc:h2:mem:test2", "sa", "");
//      JdbcConnectionPool ds = JdbcConnectionPool.create("jdbc:h2:E:/test2", "sa", "");
ds.setMaxConnections(1000);

Connection conn = ds.getConnection() ;
Statement stat = conn.createStatement();
// insert data (ddl)
String createTableSql = "";
createTableSql += "create table userInfo(                               ";
createTableSql += "    id int(4) not null primary key auto_increment,   ";
createTableSql += "    name char(20) not null,                          ";
createTableSql += "    sex int(4) not null default '0',                 ";
createTableSql += "    degree double                                    ";
createTableSql += ");                                                   ";

stat.execute( createTableSql );
//        stat.execute("CREATE TABLE TEST_TABLE(NAME VARCHAR)");

stat.execute("CREATE INDEX IDXNAME ON userInfo(NAME)");
stat.execute("INSERT INTO userInfo(name,sex,degree) VALUES('Hello World_0','0',23)");
stat.execute("INSERT INTO userInfo(name,sex,degree) VALUES('Hello World_1','1',23)");
stat.execute("INSERT INTO userInfo(name,sex,degree) VALUES('Hello World_2','2',23)");
stat.execute("INSERT INTO userInfo(name,sex,degree) VALUES('Hello World_3','3',23)");

// use data
System.err.println(" select begin ");
ResultSet result = stat.executeQuery("select id,name,sex,degree from userInfo where name like '%Hello World%'");
System.err.println(" select end ");
while (result.next()) {
System.out.println( result.getInt("id")+"|" + result.getString("name")+"|" + result.getInt("sex")+ "|" + result.getDouble("degree"));
}
result.close();
stat.close();
conn.close();

}
