Get a record count with a SQL StatementTag(s): JDBC
Statement s = conn.createStatement();
ResultSet r = s.executeQuery("SELECT COUNT(*) AS rowcount FROM MyTable");
r.next();
int count = r.getInt("rowcount") ;
r.close() ;
System.out.println("MyTable has " + count + " row(s).");
JDBC 2.0 provides a way to retrieve a rowcount from a ResultSet without
having to scan through all the rows or issue a separate SELECT COUNT(*).
Statement s = conn.createStatement( ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_READ_ONLY);
ResultSet r = s.executeQuery
("SELECT * FROM employee WHERE id_emp LIKE '1%'");
r.last();
int count = r.getRow();
r.beforeFirst();
