SSIS - Concatenating and Lookups to create a string - sql

Question

I am trying to combine many columns together to create a full string.
This is what I mean:
I have a table named QRFormats that looks like this:
| Id | Text1 | Variable1 | Text2 | Variable2 | Text3 | Variable3 |
| 1 | The Color | Color | Is designated | Description | *NULL* | *NULL* |
| 2 | The Company | Company| Is Located | Location| In Country | Country|
| 3 | The Part is | PartNumber| Work Order:| WorkOrder| *NULL* | CompanyCode |
.
.
The complete string should print the Text and lookup the Variable in completely different table using FK/PK correlations.
All the Variables are located in two possible tables called PartData and Company
PartData
| Id | PartNumber | Color | WorkOrder | Description |
| 1 | 123456789 | Blue | 111222333 | Microchip |
| 2 | 101441414 | Silver | 55556666 | Handel |
Company
| Id | Company | Location | CompanyCode | Country |
| 1 | Microsoft | Seattle | 1234 | USA |
| 2 | Apple | California | 1122 | USA |
.
Some Examples of what I am trying to do....
.
The Complete string should look as follows if my:
-QRFormats FK is a 1:
-PartDataFK is a 1:
-Company FK is a 1:
"The Color Blue Is designated Microchip"
.
The Complete string should look as follows if my:
-QRFormats FK is a 2:
-PartDataFK is a 1:
-Company FK is a 3:
"The Company Apple Is Located California In Country USA"
.
The Complete string should look as follows if my:
-QRFormats FK is a 3:
-PartDataFK is a 2:
-Company FK is a 1:
"The Part is 101441414 WorkOrder: 555566661234"
.
Thank you very much for you help, I am using SSIS in VisualStudio 2015.

This is a very interesting request. First the DML:
create table #QFR
(
Id int
, Text1 varchar(100)
, Variable1 varchar(100)
, Text2 varchar(100)
, Variable2 varchar(100)
, Text3 varchar(100)
, Variable3 varchar(100)
)
insert into #QFR
values
( 1,' The Color ','Color',' Is designated ','Description ',NULL ,NULL )
,( 2,' The Company ','Company',' Is Located ','Location',' In Country ','Country' )
,( 3,' The Part is ','PartNumber','Work Order:','WorkOrder',NULL ,'CompanyCode' )
create table #parts
(
Id int
, PartNumber varchar(100)
, Color varchar(100)
, WorkOrder varchar(100)
, Description varchar(100)
)
insert into #parts
values
(1,'123456789','Blue ','111222333',' Microchip '),
(2,'101441414','Silver ','55556666',' Handel ')
create table #company
(
Id int
, Company varchar(100),
Location varchar(100)
, CompanyCode varchar(100)
, Country varchar(100)
)
insert into #company
values
(1,' Microsoft ','Seattle ','1234',' USA ')
,(2,' Apple ','California ','1122',' USA ')
I create a CTE to flip the variable logic on its side and joined it in several times to make this work...
declare #qID int = 1
,#pID int = 1
,#cID int = 1
;with cte as
(
select Label,Value
from #parts
cross apply (values('PartNumber',PartNumber),('Color',Color),('WorkOrder',WorkOrder),('Description',Description)) as a(Label,Value)
where id =#pID
union all
select Label,Value
from #company
cross apply (values('Company',Company),('Location',Location),('CompanyCode',CompanyCode),('Country',Country)) as a(Label,Value)
where id =#cID
)
select Text1 , t1.Value , text2 , t2.Value , text3 , t3.Value
from #QFR q
left join cte t1 on q.Variable1=t1.Label
left join cte t2 on t2.Label = q.Variable2
left join cte t3 on t3.label = q.Variable3
where q.id = #qID
Changed to a function:
create function fn_BuildAsentence (#qID int
,#pID int
,#cID int)
returns varchar(max)
as
BEGIN
declare #v varchar(Max)
;with cte as
(
select Label,Value
from parts
cross apply (values('PartNumber',PartNumber),('Color',Color),('WorkOrder',WorkOrder),('Description',Description)) as a(Label,Value)
where id =#pID
union all
select Label,Value
from company
cross apply (values('Company',Company),('Location',Location),('CompanyCode',CompanyCode),('Country',Country)) as a(Label,Value)
where id =#cID
)
select #v = concat(Text1 , t1.Value , text2 , t2.Value , text3 , t3.Value)
from QFR q
left join cte t1 on q.Variable1=t1.Label
left join cte t2 on t2.Label = q.Variable2
left join cte t3 on t3.label = q.Variable3
where q.id = #qID
return #v
END
Finally, I would use a SQL Source (I presume that you are doing this in a data flow to go somewhere)
Select dbo.fn_BuildAsentence(QFR,parts,company),QFR,parts,company
from [whereever]
