在执行以下代码时，我收到错误 java.sql.SQLException: ResultSet is closed
公共类 SavePoints {
public void extract(ResultSet rs)
{
int c;
try {
while(rs.next())
{
c = rs.getInt("id");
String d=rs.getString("name");
String e=rs.getString("city");
String f=rs.getString("state");
String g=rs.getString("country");
//Displaying values
System.out.println("ID is:"+c+"\tName is:"+d+"\tCity is:"+e+"\tState is:"+f+"\tCountry is:"+g);
}
} catch (SQLException e1) {
e1.printStackTrace();
}
}
public static void main(String[] args) {
SavePoints spobj=new SavePoints();
try {
Connection con=DriverManager.getConnection("jdbc:odbc:Divya", "SYSTEM", "tiger");
Statement st=con.createStatement();
ResultSet rs=st.executeQuery("select * from publishers");
spobj.extract(rs);
//DatabaseMetaData databaseMetaData = con.getMetaData();
//System.out.println(databaseMetaData.getDriverMajorVersion());
//Savepoint sp=con.setSavepoint("Deleting Rows");
st.execute("delete from publishers where id=104");
//con.rollback(sp);
spobj.extract(rs);
} catch (SQLException e) {
e.printStackTrace();
}
}
}
