Sure it is possible. Are you having a problem with such a query?

What are you trying to do?

I have write. but it shows the error ORDER BY CLAUSE (SubcategoryTbl.SubCategoryNo) conflicts with DISTINCT..


Here is the Query.

SELECT DISTINCT PatientTbl.PatientName, PatientTbl.Address, PatientTbl.Age, PatientTbl.Sex, TestMasterTbl.LabNo, TestMasterTbl.TestDate, TestMasterTbl.PatientType, CategoryTbl.Category, SubCategoryTbl.SubCategory, TestGroupMasterTbl.Group, TestListTbl.Test, TestListTbl.NormalRange, TestDetailTbl.Value
FROM (PatientTbl INNER JOIN TestMasterTbl ON PatientTbl.PatientId = TestMasterTbl.PatientId) INNER JOIN (TestListTbl INNER JOIN ((((CategoryTbl INNER JOIN TestGroupMasterTbl ON CategoryTbl.CategoryNo = TestGroupMasterTbl.CategoryNo) INNER JOIN TestDetailGroupTbl ON TestGroupMasterTbl.GroupNo = TestDetailGroupTbl.GroupNo) INNER JOIN TestDetailTbl ON TestGroupMasterTbl.GroupNo = TestDetailTbl.GroupNo) INNER JOIN (SubCategoryTbl INNER JOIN TestGroupDetailTbl ON SubCategoryTbl.SubCategoryNo = TestGroupDetailTbl.SubCategoryNo) ON TestGroupMasterTbl.GroupNo = TestGroupDetailTbl.GroupNo) ON (TestListTbl.TestNo = TestGroupDetailTbl.TestNo) AND (TestListTbl.TestNo = TestDetailTbl.TestNo)) ON TestMasterTbl.LabNo = TestDetailTbl.LabNo
WHERE (((TestMasterTbl.LabNo)=[?]))
ORDER BY SubCategoryTbl.SubCategoryNo;


Please help.

---

The ORDER BY clause can include items not appearing in the select list. However, if SELECT DISTINCT is specified, or if the SELECT statement contains a UNION operator, the sort columns must appear in the select list.

---

Add SubCategoryNo to the select list or sort by a different field.

Thanks ...
