I am failing at doing some basic JDBC which happens to be with h2. I
am using h2-1.2.138.jar
Basic Junit test, it is basically something as challenging as a hello
world program except in this case its JDBC
Connection conn = DriverManager.getConnection("jdbc:h2:mem:");
Statement statement = null;
statement = conn.createStatement();
statement.execute("CREATE TABLE sample_table (sample_table_id
INTEGER, x_cord INTEGER, y_cord INTEGER);\n");
System.out.println("Table update count:" +
statement.getUpdateCount());
statement.close();
statement = conn.createStatement();
statement.execute("INSERT INTO sample_table (sample_table_id,
x_cord, y_cord) VALUES (0, 0, 0);\n");
System.out.println("Insert update count:" +
statement.getUpdateCount());
statement.close();
statement = conn.createStatement();
statement.execute("SELECT * from sample_table;\n");
System.out.println("Select update count:" +
statement.getUpdateCount());
System.out.println("Select more results:" +
statement.getMoreResults());
System.out.println("Select results:" + statement.getResultSet());
statement.close();
conn.close();
The output is:
Table update count:0
Insert update count:1
Select update count:-1
Select more results:false
Select results:null
I was trying to read the results of my select statement. But h2 is
telling me there are none. Obviously I am doing something wrong I
just don't know what.
