This section describes how to connect JdbcRowSet objects to database servers through JDBC drivers.
There are a number of ways you can connect a JdbcRowSet object to a database server through a JDBC driver:
1. Auto-connecting with DriverManager. A JdbcRowSet object is created without a connection object. But you provide a connection URL
before executing any SQL statements as shown below:
JdbcRowSet jrs = new JdbcRowSetImpl();
jrs.setUrl("connection_url");
jrs.setCommand("SQL_statement");
jrs.execute();
jrs.next();
String val = jrs.getString(1)
2. Predefined Connection object. A JdbcRowSet object is created with a predefined Connection object. See the sample statements below:
Connection con = DriverManager.getConnection("connection_url");
JdbcRowSet jrs = new JdbcRowSetImpl(con);
jrs.setCommand("SQL_statement");
jrs.execute();
jrs.next();
String val = jrs.getString(1)
3. Predefined ResultSet object. A JdbcRowSet object is created with a predefined ResultSet object. See the sample statements below:
Connection con = DriverManager.getConnection("connection_url");
Statement sta = con.createStatement();
ResultSet res = sta.executeQuery("SQL_statement");
JdbcRowSet jrs = new JdbcRowSetImpl(res);
jrs.next();
String val = jrs.getString(1)
4. DataSource name lookup. A JdbcRowSet object is created without any connection object. But a DataSource name is provided.
The JdbcRowSet object will do a JNDI lookup to obtain a DataSource object and create a Connection object when excute() method is called.
See the sample statements below:
JdbcRowSet jrs = new JdbcRowSetImpl();
jrs.setDataSourceName("DataSource_name");
jrs.setCommand("SQL_statement");
jrs.execute();
jrs.next();
String val = jrs.getString(1)
