Select single row of data for each ID in Select Statement
I have a need to select a single row of data based on a date range from field UDF_Date_Data for each ID to use as a dataset in my SSRS report. So I need the following Columns. That being said the UDF_FIELD Stores the names of the columns I need "In Bold Below" so I get multiple rows as seen in my data set for an ID so for instance I need all of ID 7482 in one row
'SHPMH.shpm_ref' , 'JoinFromHdrPKey' ,'FOB1VENDOR', 'FOB1DATE', 'FOB1AMT', 'FOB2VENDOR', 'FOB2DATE', 'FOB2AMT', 'MISC1VENDOR', 'MISC1DATE', 'MISC1AMT', 'MISC2VENDOR', 'MISC2DATE', 'MISC2AMT', 'DUTY1VENDOR', 'DUTY1DATE', 'DUTY1AMT', 'DUTY2VENDOR', 'DUTY2DATE', 'DUTY2AMT', 'INLAND1VENDOR', 'INLAND1DATE', 'INLAND1AMT', 'INLAND2VENDOR', 'INLAND2DATE', 'INLAND2AMT', 'OCN1VENDOR', 'OCN1DATE', 'OCN1AMT', 'OCN2VENDOR', 'OCN2DATE', 'OCN2AMT'

Do you know what that error message means? If not you should really learn how to deal with it (it will save you a lot of time).
In one of the queries I provided there is more than one table (or derived table) that has the column JoinFromHdrPKey and because there is more than 1 reference it is "ambiguous" if you don't specify which one of those 2 columns you want to use
, CTEraw AS (
SELECT
t.JoinFromHdrPKey
, t.UDF_FIELD
, t.UDF_Char_Data
, t.UDF_Date_Data
, t.UDF_Numeric_Data
FROM [dataKLL].[dbo].[KLL Extender UDF Values with Data] t
INNER JOIN CTEid r on t.JoinFromHdrPKey = r.JoinFromHdrPKey
)
where you see the yellow highlight is where I forgot to use a specific alias to ensure the query wasn't ambiguous
In truth production grade code should explicitly specify where all columns come from - this is a best practice sometimes missing from our proposed solutions

Understood, So I just about have this where it needs to be however I have records that do not contain any dates 16 thru 20. Why are these displaying? See sample data
DECLARE @start DATE;
DECLARE @end DATE;
SET @start = '20170307';
SET @end = '20170313';
