MS Access子查询

Question

下面的SQL查询需要合并，以便进一步减少结果。其中一个需要是一个子查询。我是Access的新手，我只是得到错误。最终结果应进一步过滤结果，以仅显示满足两个查询中所有条件的遭遇。这两个结果都能得到正确的结果......非常感谢您提供的任何帮助。

SELECT encounter.encounter_id，medications.encounter_id，medications.medication_id，medication_types.medication_id，medication_types.name，medication_types.class FROM medication_types INNER JOIN（遭遇INNER JOIN药物遇到.encounter_id = medications.encounter_id）ON药物_types.medication_id = medications.medication_id drug_types.class LIKE＆＃39; 抗生素＆＃39;;

SELECT encounter.encounter_id，encounter.admit_year，diseases.encounter_id，diseases.disease_id，disease_types.disease_id，disease_types.icd9cm 从遇到 INNER JOIN（disease_types INNER JOIN disease ON disease_types.disease_id = diseases.disease_id）ON encounter.encounter_iD = diseases.encounter_id 在哪里疾病_types.icd9cm IN（＆＃39; 041.3＆＃39;，＆＃39; 480.0＆＃39;，＆＃39; 480.1＆＃39;，＆＃39; 480.2＆＃39;，＆＃39; 480.3＆＃39;＆＃39; 480.8＆＃39;＆＃39; 480.9＆＃39;＆＃39; 481＆＃39;＆＃39; 482.1＆＃39;，＆＃39; 482.2 ＆＃39;＆＃39; 482.9＆＃39;＆＃39; 486＆＃39;＆＃39; V03.82＆＃39;＆＃39; V12.61＆＃39;） 和admit_week BETWEEN 5和9 AND encounter.admit_year = 2014 ORDER BY encounterters.admit_week;

如果您不需要显示药物和疾病，只需返回相遇信息，请考虑：

SELECT DISTINCT encounters.encounter_id, admit_year FROM Query2 WHERE encounters.encounter_id IN (SELECT encounters.encounter_id FROM Query1);
