Convert an Access crosstab query to T-SQL (SQL Server) - tsql

Question

I have the following crosstab query in Access:
Transform Count(1) as Count
Select Cust,[Cust#],EntryDate,CloseDate
from Tbl1,Dates
where EntryDate>=[start date]
Group by Cust,[Cust#],EntryDate,CloseDate
Order by EntryDate
Pivot Quote;
I am having difficulty converting this to T-SQL.
Should I be using SSIS for Pivot transformation in order to solve this,
or do we have an equivalent SQL Server query for this?

Answer 1

We don't really have enough information to convert that specific crosstab query, so here is a simple example that may help you achieve your goal:
For a table named [Vehicles] containing...
VehicleID VehicleMake VehicleModel VehicleType
--------- ----------- ------------ ------------
1 Ford Focus Compact car
2 Ford F-150 Pickup truck
3 Dodge RAM 1500 Pickup truck
4 Toyota Tundra Pickup truck
5 Toyota Prius Hybrid car
6 Toyota Tacoma Pickup truck
...the Access crosstab query...
TRANSFORM Count(Vehicles.VehicleID) AS CountOfVehicleID
SELECT Vehicles.VehicleType
FROM Vehicles
GROUP BY Vehicles.VehicleType
PIVOT Vehicles.VehicleMake;
...returns:
VehicleType Dodge Ford Toyota
------------ ----- ---- ------
Compact car 1
Hybrid car 1
Pickup truck 1 1 2
The following T-SQL script accomplishes the same thing
DECLARE
#ColumnList AS NVARCHAR(MAX),
#SQL AS NVARCHAR(MAX)
-- build the list of column names based on the current contents of the table
-- e.g., '[Dodge],[Ford],[Toyota]'
-- required by PIVOT ... IN below
-- ref: http://stackoverflow.com/a/14797796/2144390
SET #ColumnList =
STUFF(
(
SELECT DISTINCT ',' + QUOTENAME([VehicleMake])
FROM [Vehicles]
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)'),
1,
1,
'')
SET #SQL = '
WITH rollup
AS
(
SELECT VehicleMake, VehicleType, COUNT(VehicleID) AS n FROM [Vehicles]
GROUP BY VehicleMake, VehicleType
)
SELECT * FROM rollup
PIVOT (SUM([n]) FOR [VehicleMake] IN (' + #ColumnList + ')) AS Results'
EXECUTE(#SQL)
It returns:
VehicleType Dodge Ford Toyota
------------ ----- ---- ------
Compact car NULL 1 NULL
Hybrid car NULL NULL 1
Pickup truck 1 1 2

Answer 2

drop table #tmpT1
select distinct UserField2 into #tmpT1 from CreateExcelForm
--select * from #tmpT1
DECLARE #PivotColumnHeaders VARCHAR(MAX)
SELECT #PivotColumnHeaders =
COALESCE(
#PivotColumnHeaders + ',[' + cast(UserField2 as varchar) + ']',
'[' + cast(UserField2 as varchar)+ ']'
)
FROM #tmpT1
print(#PivotColumnHeaders)
DECLARE #PivotTableSQL NVARCHAR(MAX)
SET #PivotTableSQL = N'
SELECT *
FROM (
SELECT
* from CreateExcelForm
) AS PivotData
PIVOT (
max(StockCode)
FOR UserField2 IN (
' + #PivotColumnHeaders + '
)
) AS PivotTable
'
EXECUTE(#PivotTableSQL)
