示例1: addJoinOnColumns
import com.taobao.tddl.optimizer.core.ast.query.JoinNode; //導入方法依賴的package包/類
private void addJoinOnColumns(IFilter ifilter, JoinNode joinNode) {

// 比如出現 A.id = B.id And ( A.id = 1 or A.name = 3)
// 這裏的or條件可直接做為other join filter
// 如果出現 A.id = B.id OR A.name = B.name，那就是一個未知情況了
