假定Test实体表名为T_TEST, 含有id, type, name, value, desc字段:
主键更新:
Test test = new Test(); test.setType(1); test.setId("uuid"); testService.update(test); // UPDATE T_TEST SET TYPE = 1 WHERE ID = 'uuid'; |
更新,列的值为空的更新NULL:
Test test = new Test(); test.setType(1); test.setId("uuid"); // UPDATE T_TEST SET TYPE = 1, NAME = NULL,VALUE = NULL,DESC = NULL WHERE ID = 'uuid'; testService.update(test, true); |
更新,指定列的值为空的更新NULL:
Test test = new Test(); test.setType(1); test.setId("uuid"); // UPDATE T_TEST SET TYPE = 1, NAME = NULL,VALUE = NULL WHERE ID = 'uuid'; testService.update(test, Test.T_NAME, Test.T_VALUE); |
按条件更新(也适合无主键更新或复核主键):
Test test = new Test(); test.setType(1); // UPDATE T_TEST SET TYPE = 1 WHERE NAME = 'abc'; testService.updates(test, new Express(Test.T_NAME, "abc", ExpressionType.CDT_Equal)); |
按条件更新,列的值为空的更新NULL:
Test test = new Test(); test.setType(1); // UPDATE T_TEST SET TYPE = 1, NAME = NULL,VALUE = NULL,DESC = NULL WHERE NAME = 'abc'; testService.updatesNull(test, new Express(Test.T_NAME, "abc", ExpressionType.CDT_Equal)); |
按条件更新,指定列的值为空的更新NULL:
Test test = new Test(); test.setType(1); // UPDATE T_TEST SET TYPE = 1, VALUE = NULL WHERE NAME = 'abc'; testService.updatesNull(test, new String[]{Test.T_VALUE}, new Express(Test.T_NAME, "abc", ExpressionType.CDT_Equal)); |
