Transact SQL :: Casting A Variable To Nested Table?
Sep 24, 2015
Is there any way to convert a bind variable, which is a list of integer or string values, to nested table in MS SQL Server. I am looking for something like
CAST in Oracle, which converts a varray type column into a nested table. Do we have something like this in SQL Server.
in Oracle:
SELECT CAST(s.addresses AS address_book_t)
FROM states s
WHERE s.state_id = 111;
I have read about Table valued Parameter, but I am looking for another solution.

I have been wrestling with the code all day to accomplish the following: I need to update a table based on values from another table. So far, I have been able to do the below:
DECLARE @LookUpTerm VARCHAR(25)
, @SearchCol VARCHAR(255)
, @LogonIDToProcess VARCHAR(50)
, @Matched CHAR
, @Cycle INT = 1
IF OBJECT_ID('tempdb..#Glossary','U') IS NOT NULL DROP TABLE #Glossary
IF OBJECT_ID('tempdb..#Employees','U') IS NOT NULL DROP TABLE #Employees

I have a parameter which should take multiple values into it and pass that to the code that i use. For, this i created a parameter and temporarily for testing i am passing some values into it.Using a dynamic SQL i am converting multiple values into multiple records as rows into another variable (called @QUERY). My question is, how to insert the values from variable into a table (table variable or temp table or CTE).OR Is there any way to parse the multiple values into a table. like if we pass multiple values into a parameter. those should go into a table as rows.

Biz talk server executes every query twice, first with FMT only to get metadata.If metadata changed, it will produce error.Now, i have query like:
SELECT col1, col2, col3 INTO #tmp FROM dbo.myTable
How SQL decide the type of column in #tmp? Does it create column of the same type as it is in dbo.myTable or its decision is based on result?For example, col1 is varchar(20), but col1 in #tmp will be varchar(200) or even nVarChar.Col2 is INT, but result is for example low number(like, 1,2,3,) - is it possible that col2 in #temp table will be smallint or tinyint even if col2 in myTable is INT.If that is true one way to overcome that will be to explicitly CAST all columns to proper data type. Is there any performance impact of casting: CAST(col1 as VARCHAR(20)) if col1 is already varchar(20) in dbo.myTable?

if I 'print' a MONEY value, or cast a MONEY variable to VARCHAR, it automatically rounds it to two decimal places. Maybe that's a built-in convenience, but I'd like to make it not do that.My workaround right now is to first cast my MONEY variabled to DECIMAL(30,4), and then cast the result to VARCHAR, but I'd like to avoid that step if possible.Consider the following
query:DECLARE @UnitCost MONEY SET @UnitCost = .0167 SELECT @UnitCost,
CAST(@UnitCost AS VARCHAR(30)),
CAST(CAST(@UnitCost AS DECIMAL(30, 4)) AS VARCHAR(30)) -
- Results in: 0.0167, 0.02, 0.0167

Condition in Where clause:
cast(isNull(tab1.Col1,'') as datetime) <> cast(isNull(tab2.col1,'') as datetime)

I need to use a nested cursor in SQL server 2005. I have never done this before. The problem here is that I need to use "@@FETCH_STATUS' twice.Once for my inner loop and once for my outer loop. If there is a way to use two different @@FETCH_STATUS variables at once, I would like to know how.
Here is my code. The inner loop is currently pseudo code and I just need to figure out how to code it.

We are trying to create a model of linear regression with nested table. We used the create mining model sintax as follow :
create mining model rate_plan3002_nested2
( CUST_cycle LONG KEY,
VOICE_CHARGES double CONTINUOUS predict,
DUR_PARTNER_GRP_1 double regressor CONTINUOUS ,
nested_taarif_time_3002 table
( CUST_cycle long CONTINUOUS,
TARIFF_TIME text key,
TARIFF_VOICE_DUR_ALL double regressor CONTINUOUS
)
) using microsoft_linear_regression
INSERT INTO MINING STRUCTURE [rate_plan3002_nested2_Structure]
(CUST_cycle ,
VOICE_CHARGES ,
DUR_PARTNER_GRP_1 ,
[nested_taarif_time_3002](SKIP,TARIFF_TIME ,TARIFF_VOICE_DUR_ALL)
)
SHAPE {
OPENQUERY([Cell],
'SELECT CUST_cycle ,
VOICE_CHARGES ,
DUR_PARTNER_GRP_1
FROM dbo.panel_anality_3002
order by CUST_cycle ')}
APPEND
({OPENQUERY([Cell],
'select CUST_cycle,
TARIFF_TIME,
CYCLE_DATE
from dbo.nested_taarif_time_3002
order by CUST_cycle,TARIFF_TIME')
}
relate CUST_cycle to CUST_cycle
) as nested_taarif_time_3002
The results we got are a model with intercept only. if we don't use the nested variable (the red line) we get a rigth model . (we had more variable ....)
Is there a way to do this regression correctly?
Thanks,

All:
I am trying to code the following SQL into an OLEDB data source but it is not allowing me to do so because I think the variables are nested in multiple SQL statements. I have seen other posts that suggest using a variable to store the SQL but I am not sure how it will work.
I would also like to mention that the OLEDB source executes from within a For Each loop that is actually passing the values for the variables, which was one of the reasons I got stumped on how I could have a variable store the SQL.
Here is the SQL:
select b.ProgramID, b.ProductCode, b.BuyerID, b.Vendor,sum(a.Ordered) As Qty_Pruchased
From SXE..POLine a INNER JOIN
(SELECT VIR_Program.ProgramID, VIR_ActiveSKU.ProductCode, VIR_ActiveSKU.BuyerID, Vendor
FROM VIR_Program INNER JOIN
VIR_ActiveSKU ON VIR_Program.ProgramID = VIR_ActiveSKU.ProgramID
INNER JOIN Vendor ON VIR_Program.VendorID = Vendor.VendorID
WHERE ProgramFreq=?) b
ON a.ProductCode = b.ProductCode
WHERE a.TransDate >=? AND
a.TransDate ?
Group By b.ProgramID, b.ProductCode, b.BuyerID, b.Vendor
Thanks!

If i change the connector to REPLPROD (which is a linked server): From REPLPROD.XUNMDTAUAI.dbo.UPPOREP UP INNER JOIN REPLPROD.XUNMDTAUAI.dbo.UKKMREP UK
I get the error:

I need to perform an update where there are multiple scenarios which determine the value that is entered. Below is a sort've psuedo code of how it needs to be.
Update MyTable SET MyColumn = CASE WHEN MyCol1 = 'Value1' Then NewValue Else
WHEN MyCol1 <> 'Value1' And MyCol2 = 'Active' Then 'Value1'
In the scenario where MyCol1 <> Value1 and MyCol2 <> 'Active' then no update would occur and the original value would remain intact.

Does fetch status in nested loops conflict?I have a script that should output a cluster record line and for each cluster record it must create a line for each household in the cluster. All the data is pulled from one table, 'LFS_APRIL_2015.dbo.LISTING'.This is the script:
--VARIABLE DECLARATION
DECLARE @CLUSTER FLOAT, @HOUSEHOLD_NUMBER FLOAT, @FULL_ADDRESS CHAR(50), @HEAD_NAME CHAR(24)--CLUSTER LOOP
DECLARE CLUSTER_CURSOR CURSOR FOR
SELECT [LFS_APRIL_2015].[dbo].[LISTING].CLUSTER
from [LFS_APRIL_2015].[dbo].[LISTING] where CLUSTER IS NOT NULL and DISTRICT = 1
OPEN CLUSTER_CURSOR
[code]...
It appears however that the clusters are being repeated.

Hi, all experts here,
Thank you very much for your kind attention.
I am trying to create a new mining structure with case table and nested table, the case table (fact table) has alread defined the relationships with the nested table(dimension table), and I can see their relationship from the data source view. But why the wizard for creating the new mining structure showed that message? Why is that? And what could I try to fix it?
Hope it is clear for your help.
Thanks a lot for your kind advices and I am looking forward to hearing from you shortly.
With best regards,
Yours sincerely,

Why would someone choose to model a problem with a case and nested table versus just using a case tables with multiple rows?
For example, a simple customer and product scenario where you could say:
Mining Model DT_CustProd
(
[Id] ,
[Gender] ,
[Age]
[Products] Predict
(
[ProductName] ,
[Quantity]
)
)
But you could also model as:
Mining Model DT_CustProd
(
[Id] ,
[Gender] ,
[Age]
[ProductName] Predict,
[Quantity] Predict
)
and just insert multiple rows per Id/Gender/Age? Is there any rule of thumb to use here when deciding to model with a nested table?
I understand that a nested table essentially pivots the data (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=408840&SiteID=1) and the data becomes an attribute, but how do you know if you want that, or you want the data as a value of an attribute?

Hi, all here,
I have a question about nested table use. I dont quite clearly see through why the nested table is very much necessary? I mean if we need information from both the current case table and nested table for mining models, we can just join both tables?
Thanks a lot in advance for any guidance and help.

Hi all,
I have been struggling with the below transact sql user defined function. I want to use a transact sql variable in an "in" statement. I don't get any results and I am not sure if I am receiving an error or not.
Code:
DECLARE @myval varchar(50),@username varchar(50)
DECLARE @rolelist varchar(2000)
SET @rolelist = ''
SET @myval = 'user a,user b'
select @myval = ''''+ replace(@myval,',',''',''') + ''''
print @myval
DECLARE User_Cursor CURSOR FOR
select distinct eusername
from euser
where eusername in (@myval)
OPEN User_Cursor
FETCH NEXT FROM User_Cursor INTO @username
SET @myval = @username
SET @rolelist = @username
WHILE @@FETCH_STATUS = 0
BEGIN
SET @rolelist =+ @rolelist + ',' + @username
FETCH NEXT FROM User_Cursor INTO @username
END
CLOSE User_Cursor
DEALLOCATE User_Cursor
print @myval
print 'rolelist' + @rolelist
GO
I am at a loss any suggestions would be greatly appreciated.

Hey gang,
I'm having some issues with nested table. This is my setup. [ProductTable] is the case table, and [CustomersTable] is a nested table. I'm trying to organize my algorithms around products.
[ProductTable]<---[CustomersTable]
[ProductTable] table only has product ID, and it is key.
[CustomersTable] table has variety of customer attributes (productID, customerID, location, demographics...) and CustomerRevenue is predict_only. ProductName is the key for the nested table.
I keep getting this error when I'm processing the mining models (Logical Regression and Neural Net).
Error (Data mining): In mining model, Estimate Neural Net, the algorithm does not allow table column as predictable.
Error (Data mining): Error validating attribute for the 'Estimate Neural Net' mining model.
When using Decision Tree, it processes OK, but the result is totally wrong. The model is empty.
Any ideas?
-Young K.
P.S. I'm trying to great a single model for multiple products. This is a label saving device that I'm trying. If this doens't work, I'll have to create a model for each product.

Hi all,
What is the equivalent for Oracle's nested table concept in SQL Server ?
Is there anything like TABLE( ) function to select from nested table as in Oracle ?
Eg in Oracle :
SELECT t.* FROM TABLE(nested_table_datatype) t;
( like the above query used in Oracle PL/SQL and 'nested_table_datatype' is a table datatype created in Oracle using 'create type ...' syntax )
Please give the equivalent for above...
Thanks,
Sam

hi all,
i have speed issue on displaying 4k line of records using temp table.. before this it works fine and fast.. but maybe when i starts joining group by it loads slower.
SELECT DISTINCT customlotno, itemid, ItemName, Ownership, TotalCTNInPlt, TotalCarton, sum(CartonPcs) AS CartonPcs, StorageID, StorageStatus ,OriginUOM, PickQtyUOM, WhsID, WhsName, LocID, Zone, Expirydate, recvDate
INTO #ByItemID
FROM (
SELECT * FROM tblItemdetail
)AS L1
GROUP BY customlotno, itemid, ItemName, ownership, TotalCTNInPlt, TotalCarton, StorageID, StorageStatus ,OriginUOM, PickQtyUOM, WhsID, WhsName, LocID, Zone, Expirydate, recvDate
SELECT *
FROM #ByItemID
ORDER BY CustomLotNo
DROP TABLE #ByItemID
----------------------------
or maybe just use something like nested SELECT like this, but cannot work:-
select customlotno, itemid, locid(
select * from tblitemdetail
where customlotno='IN28606000'
) AS T
GROUP BY customlotno, itemid, locid
~~~Focus on problem, not solution~~~

I am running the DMX below and I am getting an error we I go to train my structure. It is probably something stupid but I do not see the problem. It seems like the SKIP isn't being recognized but I am not sure. Here is the error:
INSERT INTO error: The '[MSA].[HospitalID]' nested table key column is not bound to an input rowset column.
DMX:
CREATE MINING STRUCTURE [Hospital_Structure] (
[HospitalID] LONG KEY,
[SponsorshipTypeID] LONG DISCRETE,
[GeographicTypeID] LONG DISCRETE,
[CaseMixIndex] DOUBLE CONTINUOUS,
[PercentGovtPayers] DOUBLE CONTINUOUS,
[TotalNumberInpatientCases] LONG CONTINUOUS,
[MSA] TABLE (
[HospitalID] LONG KEY,
[MSAGroupMember] TEXT DISCRETE
)
);
GO
ALTER MINING STRUCTURE [Hospital_Structure]
ADD MINING MODEL [Hospital_Model] (
[HospitalID],
[SponsorshipTypeID],
[GeographicTypeID],
[CaseMixIndex],
[PercentGovtPayers],
[TotalNumberInpatientCases],
[MSA] (
[HospitalID],
[MSAGroupMember]
)
) USING Microsoft_Clustering;
GO
INSERT INTO MINING STRUCTURE [Hospital_Structure]
(
[HospitalID],
[SponsorshipTypeID],
[GeographicTypeID],
[CaseMixIndex],
[PercentGovtPayers],
[TotalNumberInpatientCases],
[MSA] (SKIP, [MSAGroupMember])
)
SHAPE {
OPENQUERY([localhost],'
SELECT
[HospitalID],
[SponsorshipTypeID],
[GeographicTypeID],
[CaseMixIndex],
[PercentGovtPayers],
[TotalNumberInpatientCases]
FROM
[dm].[vw_HospitalClustering_Inputs]
ORDER BY
[HospitalID]') }
APPEND
(
{OPENQUERY([localhost],'
SELECT
[HospitalID],
[MSAGroupMember]
FROM
[dm].[vw_HospitalClustering_InputsNested]
ORDER BY
[HospitalID],
[MSAGroupMember]')
}
RELATE [HospitalID] TO [HospitalID]
) AS [MSA]
Thanks in advance

If your prediction join is to a SQL datasource, you can easily write a SQL query which returns a nested table like:
SELECT
Predict([Subcategories],2) as [Subcategories]
FROM
[SubcategoryAssociations]
NATURAL PREDICTION JOIN
(SELECT
(SELECT 'Road Bikes' AS Subcategory
UNION SELECT 'Jerseys' AS Subcategory
) AS Subcategories
) AS t
What about if your datasource is a cube? Is there some special MDX syntax similar to the SQL syntax above? Or do you have to utilize the SHAPE/APPEND syntax as follows?
SELECT t.*, $Cluster as ClusterName
FROM [MyModel]
PREDICTION JOIN
SHAPE {
select [Measures].[My Measure] on 0,
[My Dimension].[My Attribute].[My Attribute].Members on 1
from MyCube
}
APPEND (
{
select [Measures].[Another Measure] on 0,
NON EMPTY [My Dimension].[My Attribute].[My Attribute].Members
*[Product].[Product].[Product].Members on 1
from MyCube
}
RELATE [[My Dimension]].[My Attribute]].[My Attribute]].[MEMBER_CAPTION]]]
TO [[My Dimension]].[My Attribute]].[My Attribute]].[MEMBER_CAPTION]]]
)
AS [My Nested Table] AS t
ON [MyModel].[Product].[Product] = t.[My Nested Table].[[Product]].[Product]].[Product]].[MEMBER_CAPTION]]]
