示例2: TableNode
import com.taobao.tddl.optimizer.core.ast.query.JoinNode; //导入方法依赖的package包/类
@Test
public void test_两表join_orderby_groupby_limit条件() {
TableNode table = new TableNode("TABLE1");
JoinNode join = table.join("TABLE2", "ID", "ID");
join.select(OptimizerUtils.createColumnFromString("TABLE1.ID AS JID"),
OptimizerUtils.createColumnFromString("CONCAT(TABLE1.NAME,TABLE1.SCHOOL) AS JNAME"));
join.orderBy("JID");
join.groupBy("JNAME");
join.having("COUNT(JID) > 0");
IQueryTree qc = (IQueryTree) optimizer.optimizeAndAssignment(join, null, extraCmd);
Assert.assertTrue(qc instanceof IMerge);
Assert.assertEquals(QUERY_CONCURRENCY.CONCURRENT, ((IMerge) qc).getQueryConcurrency());// 串行
