I do not know if i got you right, anyway you said that a clearance may have a tax certificate sounds to me that you cannot make direct reference between the tax certificate and document but thru clearance table. if this is the case you will have something like this.

SELECT * 
FROM DOCUMENT INNER JOIN
CLEARANCE ON CLEARANCE.DOCUMENT_ID = DOCUMENT.ID LEFT OUTER JOIN TAX_CERTIFICATE ON TAX_CERTIFICATE.ID_CLEARANCE = CLEARANCE.ID

I may be wrong but you can show a little bit more of your table structure to give a more accurate answer.

When you say document>certificate what exactly is certificate for you here, because i do not see any certificate table?

oh fudge. sorry. it's document>clearance. :)

Ok.

SELECT *
FROM DOCUMENT INNER JOIN
CLEARANCE ON CLEARANCE.DOC_ID = DOCUMENT.DocNo LEFT OUTER JOIN
SEDULA ON SEDULA.DOC_ID = CLEARANCE.DOC_ID

Try that.

hey thanks it works. i want to display these:

SELECT Document.DocNo, Document.PersonID, Clearance.DocID, Sedula.DocID, Receipt.DocID, Officer.OfficerID,
          (Person.Givenname + SPACE(1) + Person.Middlename + SPACE(1) + Person.Lastname) AS Name,
          Person.Address, 
          CASE WHEN DATEADD(YEAR, DATEDIFF (YEAR, Person.DOB, CURRENT_TIMESTAMP), Person.DOB) > CURRENT_TIMESTAMP
               THEN DATEDIFF(YEAR, Person.DOB, CURRENT_TIMESTAMP) - 1
               ELSE DATEDIFF(YEAR, Person.DOB, CURRENT_TIMESTAMP) 
          END AS 'Age',
          Person.Status, Person.Picture, Person.Citizenship,
          Clearance.Findings, Clearance.Purpose,
          Sedula.CTCNo, Document.PlaceIssued,

		  (Officer.Givenname + SPACE(1) + Officer.Middlename + SPACE(1) + Officer.Lastname) AS Officer
		  FROM Document
			INNER JOIN CLEARANCE ON CLEARANCE.DocID = DOCUMENT.DocNo 
			INNER JOIN Receipt ON Receipt.DocID = DOCUMENT.ORNo
			LEFT OUTER JOIN Sedula ON Sedula.DocID = Clearance.CTCNo

but i get errors,

oh nevermind, it's fine now.

SELECT Document.DocNo, 
          (Person.Givenname + SPACE(1) + Person.Middlename + SPACE(1) + Person.Lastname) AS Name,
          Person.Address, 
          CASE WHEN DATEADD(YEAR, DATEDIFF (YEAR, Person.DOB, CURRENT_TIMESTAMP), Person.DOB) > CURRENT_TIMESTAMP
               THEN DATEDIFF(YEAR, Person.DOB, CURRENT_TIMESTAMP) - 1
               ELSE DATEDIFF(YEAR, Person.DOB, CURRENT_TIMESTAMP) 
          END AS 'Age',
          Person.Status, Person.Picture, Person.Citizenship,
          Clearance.Findings, Clearance.Purpose,
          Sedula.CTCNo, Document.PlaceIssued, Document.DateIssued AS CTCDIssued,
		  Receipt.ORno, Receipt.Amount, Receipt.DateIssued AS ReceiptDIssued,

		  FROM Document
			INNER JOIN CLEARANCE ON CLEARANCE.DocID = DOCUMENT.DocNo 
			INNER JOIN Receipt ON Receipt.DocID = DOCUMENT.ORNo

SELECT *
      FROM DOCUMENT INNER JOIN
      CLEARANCE ON CLEARANCE.DOC_ID = DOCUMENT.DocNo LEFT OUTER JOIN
      SEDULA ON SEDULA.DOC_ID = CLEARANCE.DOC_ID INNER JOIN PERSON ON PERSON.PersonID = DOCUMENT.PesonID INNER JOIN
OFFICER ON OFFICER.OfficerID = DOCUMENT.OfficerID

notice that in order to get information from person in officer table you have to make the links.

Ok. Glad to know.

oops. i think there's a problem

SELECT Document.DocNo, 
          (Person.Givenname + SPACE(1) + Person.Middlename + SPACE(1) + Person.Lastname) AS Name,
          Person.Address, 
          CASE WHEN DATEADD(YEAR, DATEDIFF (YEAR, Person.DOB, CURRENT_TIMESTAMP), Person.DOB) > CURRENT_TIMESTAMP
               THEN DATEDIFF(YEAR, Person.DOB, CURRENT_TIMESTAMP) - 1
               ELSE DATEDIFF(YEAR, Person.DOB, CURRENT_TIMESTAMP) 
          END AS 'Age',
          Person.Status, Person.Picture, Person.Citizenship,
          Clearance.Findings, Clearance.Purpose,
          Sedula.CTCNo, Document.PlaceIssued, Document.DateIssued AS CTCDIssued,
		  Receipt.ORno, Receipt.Amount, Receipt.DateIssued AS ReceiptDIssued,
		  (Officer.Givenname + SPACE(1) + Officer.Middlename + SPACE(1) + Officer.Lastname) AS Officer
		  FROM Document
			INNER JOIN CLEARANCE ON CLEARANCE.DocID = DOCUMENT.DocNo 
			INNER JOIN Receipt ON Receipt.DocID = DOCUMENT.ORNo
			LEFT OUTER JOIN Sedula ON Sedula.DocID = Clearance.CTCNo
			INNER JOIN Officer ON Officer.OfficerID = Document.OfficerID 
			INNER JOIN Person ON Person.PersonID = Document.PersonID

i want the code on line 10 to display the place and date issued of the sedula document

[B]Document.PlaceIssued, Document.DateIssued AS CTCDIssued,[/B]

but when i run the query, it returns the place and date issued of the clearance,not the sedula.

suggestions?

Then you cannot reference the sedula table thru the clearance table, just make the left outer join with document table. that should do it.

0

Try replacing the left outer join with this
"LEFT OUTER JOIN Sedula ON Sedula.DocID = Document.DocNo" if that does not work I think you have to go over the design again, maybe if you explain a little bit what is the relation between these three tables i can help you finding any design problem.
