示例1: testUpdate

import com.taobao.tddl.optimizer.core.plan.dml.IUpdate; //導入依賴的package包/類
@Test
public void testUpdate() {
    String sql = "UPDATE TABLE1 SET NAME = ? WHERE ID = ?";

    Map<Integer, ParameterContext> currentParameter = new HashMap<Integer, ParameterContext>();
    ParameterContext p1 = new ParameterContext(ParameterMethod.setObject1, new Object[] { 2 });
    currentParameter.put(1, p1);

    Parameters parameterSettings = new Parameters();
    parameterSettings.getCurrentParameter().put(1,
        new ParameterContext(ParameterMethod.setObject1, new Object[] { 1, "hello1" }));
    parameterSettings.getCurrentParameter().put(2,
        new ParameterContext(ParameterMethod.setObject1, new Object[] { 2, 1 }));
    parameterSettings.addBatch();

    parameterSettings.getCurrentParameter().put(1,
        new ParameterContext(ParameterMethod.setObject1, new Object[] { 1, "hello2" }));
    parameterSettings.getCurrentParameter().put(2,
        new ParameterContext(ParameterMethod.setObject1, new Object[] { 2, 2 }));
    parameterSettings.addBatch();

    IDataNodeExecutor plan = optimizer.optimizeAndAssignment(sql, parameterSettings, null, false);
    Assert.assertTrue(plan instanceof IMerge);
    Assert.assertEquals(((IUpdate) ((IMerge) plan).getSubNodes().get(0)).getBatchIndexs(), Arrays.asList(0));
    Assert.assertEquals(((IUpdate) ((IMerge) plan).getSubNodes().get(1)).getBatchIndexs(), Arrays.asList(1));
