Good Afternoon all.
I am trying to create a stored procedure that can pull the last date entered. The catch is that the last date entered could be in either of 4 different fields, rather than a collection where I could just Max(columnname). While this does get me most of the information I need, it gives me all of the dates, just not the latest one. I thought about going backward, if CustField #4 is null, then check #3. If #3 is Null, check #2, etc...but, I am having difficulty with the syntax.
Any help would be greatly appreciated
Here's what I have so far:
SELECT mwlLoanApp.LoanNumber,
mwlLoanApp.AppNum,
mwlBorrower.LastName,
mwlCustomField.DateValue,
mwlCustomField.CustFieldDef_ID,
mwlLoanApp.OriginatorName,
mwlLoanApp.ProcessorName,
mwlLoanApp.TransType,
mwlLoanData.LoanProgramName,
mwlLoanApp.EstCloseDate
FROM mwlLoanApp INNER JOIN
mwlBorrower ON mwlLoanApp.ID = mwlBorrower.LoanAPP_ID INNER JOIN
mwlLoanData ON mwlLoanApp.ID = mwlLoanData.ObjOwner_ID INNER JOIN
mwlCustomField ON mwlLoanApp.ID = mwlCustomField.LoanApp_ID JOIN
(
SELECT LoanApp_ID,
Max(DateValue) as DateValue
FROM mwlCustomField
GROUP BY LoanApp_ID
) AS X
ON mwlCustomField.LoanApp_ID = X.LoanApp_ID
WHERE (mwlBorrower.SequenceNum = '1')
AND (mwlCustomField.CustFieldDef_ID = '768CA20DB9CF492AB633A919DFC5EA48' /CustomField#1/
OR mwlCustomField.CustFieldDef_ID = 'CDCAE4277D10465F8960853976EAE6B6' /CustomField#2/
OR mwlCustomField.CustFieldDef_ID = 'C6B0C4C8B67D4B9589B91104BE7FCF54' /CustomField#3/
OR mwlCustomField.CustFieldDef_ID = '781DED61758C4001B24D56F971E1B4E4') /CustomField#4/
