Partitioning Column Was Not Found
Feb 14, 2008
CREATE VIEW [dbo].[pv_mainQAStatus] as
SELECT
[QAAccountID], [FunctionalAreaID],
[EvaluationStartDate], [EvaluationEndDate]
FROM
[PA_mainQAStatus]
UNION ALL
SELECT
[QAAccountID], [FunctionalAreaID],
[EvaluationStartDate], [EvaluationEndDate]
FROM
[CS_mainQAStatus]
UNION ALL
SELECT
[QAAccountID], [FunctionalAreaID],
[EvaluationStartDate], [EvaluationEndDate]
FROM
[GV_mainQAStatus]
In all the 3 tables I have QAAccountID and FunctionalAreaID as Primary key. I am getting this error when I try to insert
'UNION ALL view 'pv_mainQAStatus' is not updatable because a partitioning column was not found.'
How to over come this. I am used to writing an INSTEAD OF Trigger.

Hi,I don't know if I missed anything. I have 2 member tables and onepartition view in SQL 2000 defined as followingCREATE VIEW Server1.dbo.UTableASSELECT*FROMServer1..pTable1UNION ALLSELECT*FROMServer2..pTable2CREATE TABLE pTable1 ([ID1] [int] IDENTITY (1000, 2) NOT NULL ,[ID2] [int] NOT NULL ,...<other columns>.........CONSTRAINT [PK_tblLot] PRIMARY KEY CLUSTERED([ID1],[ID2]) ON [PRIMARY] ,CHECK ([ID2] = 1015)) ON [PRIMARY]CREATE TABLE [pTable2] ([ID1] [int] IDENTITY (1001, 2) NOT NULL ,[ID2] [int] NOT NULL ,...<other columns>.........CONSTRAINT [PK_tblLot] PRIMARY KEY NONCLUSTERED([ID1],[ID2]) WITH FILLFACTOR = 90 ON [PRIMARY] ,CHECK ([ID2] <1015)) ON [PRIMARY]SELECT is working fine. However, I got error message if I issue anupdate command such asUPDATE UTableSET somecol = somevalWhere somecol2 = somecondServer: Msg 4436, Level 16, State 12, Line 1UNION ALL view 'UTable' is not updatable because a partitioning columnwas not found.Anyone have any idea? ID2 is my partition column, why the SQL 2Kdoesn't see it. It is a part of primary key, having checkingconstrain, and no other constrain on it. Am I missing something?Thanks a lot.

We are facing few issues pertaining to creation of primary key on a non - partitioned column in sql server 2005. Herewith attaching the text file containing the detailed scenario.
Pls advice.
Pls find some of the scenario with the example given below:
We have done the following steps
1.Creating a Partition Function
CREATE PARTITION FUNCTION pf_EncounterODS_StateID (CHAR(2))
AS RANGE RIGHT FOR VALUES
(
'CA', -- CA
'MI', -- MI
'NM', -- NM
'OH', -- OH
'TX', -- TX
'UT', -- UT
'WA' -- WA
)
GO
2.Creating a Partition Schema
CREATE PARTITION SCHEME [ps_EncounterODS_StateID]
AS PARTITION pf_EncounterODS_StateID TO
(
[PRIMARY],
[ENC_DM_DATA_01], -- CA
[ENC_DM_DATA_03], -- MI
[ENC_DM_DATA_04], -- NM
[ENC_DM_DATA_05], -- OH
[ENC_DM_DATA_06], -- TX
[ENC_DM_DATA_07], -- UT
[ENC_DM_DATA_02] -- WA
)
GO
3.Creating a table using above partitioned schema
CREATE TABLE [dbo].[Fact] (
[ValidationErrorSID] [bigint] NOT NULL IDENTITY(1,1),
[ProcessID] [int] NULL ,
[StateID] [char] (2) NOT NULL ,
[ClaimID] [char] (15) NULL ,
) ON [ps_EncounterODS_StateID](StateID)
4.Creating a primary key on validationErrorSID column in the fact table
ALTER TABLE [Fact] ADD CONSTRAINT NQValidationError PRIMARY KEY CLUSTERED ([ValidationErrorSID])
Step 4 throws an error as
---------------------------------
Column 'StateID' is partitioning column of the index 'NQValidationError'. Partition columns for a unique index must be a subset of the index key.
If we include StateID along with ValidationErrorSID for index,then it works fine.But we need to have only ([ValidationErrorSID]) for indexing.

We have a database and have 6-7 growing tables. All the tables have Primary and foreign key relation. I want to do partition based on the date column.
I need 3 partitions
First partition has to hold present data
second partition need to hold the previous year data (SAS storage)
Third partition need to hold all the old data and need to be in the archive database
I understand that first we need to disable the constraints (Indexes PK & FK)
Then create partition function and partition schema
Then Create the Constraints again

I am getting an error importing a csv file both using SSIS and SSMS. The csv is comma delimited with quotes for text qualifiers. The file gets partially loaded and then gives me an error stating The column delimiter for column "MyColumn" was not found. In SSIS it gives me the data row which is apparently causing the problem but when I look at the file in a text editor at the specific row identified the file has the comma delimiter and it looks fine. I am using SQL Server 2008.

I have a requirement of table partitioning. we have 10 years of data on a table which is 30 billion up rows on 2005 server we are upgrading it to 2014. we have to keep 7 years of data. there is no keys on table or date column. since its a huge amount of data and many users its slow down the process speed. we are thinking to do partition on 7 years for Quarterly based. but as i said there is no date column on table we have to use reference table to get date. is there a way i can do the partitioning with out adding date column on table? also does partition will make query faster?
I have think three ways to do it.
1. leave as it is.
2. 7 years partition on one server
3. 3 years partition on server1 and 4 years partition on server2 (for 4 years is snapshot better?)

This is a followup to a previous question to a previous but in reverse of Find rows where value in column not found in another row
Given one table, Table1, with columns Key1 (int), Key2 (int), and Type (varchar)...
I would like to exclude any two rows where Type is equal to 'TypeA' and Key2 is Null that have a corresponding row in the table where Type is equal to 'TypeB' and Key2 is equal to Key1 from another row.
So, given the data
**KEY1** **Key2** **Type**
1 NULL TypeA
2 5 TypeA
3 1 TypeB
4 NULL TypeA
5 NULL TypeB
6 26 TypeC
7 NULL TypeD
8 NULL TypeD
I would like to return all the rows except where Key=1 and Key=3 because those rows together meet the criteria of Type='TypeA'/Key2=NULL and does have a corresponding row with Type='TypeB'/Key1=Key2.

Good morning,
I have written a package which accepts variables for the server, initial catalog & table name.
I execute sql to drop the following stored procedure, then following sql statement to create it.
================================================================
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE procedure [dbo].[SP_CreateMatchProc]
@sTable varchar(300)
as
BEGIN
SET NOCOUNT ON
declare @cmd nvarchar(2000)
set @cmd = ''''
Set @cmd = 'SELECT REPLACE(field1 + field2 + field3 + field4 + field5, '' '', '''') AS dBString '
+ 'FROM ' + @sTable + ' ORDER BY <table>_ID COLLATE Latin1_General_CI_AS'
exec (@cmd)
END
GO
================================================================
Then in the Oledb source (validateexternalmetadata = false) I use "sqlcommand from variable" with a variable value of "SP_CreateMatchProc '<tableName>'"
The package runs fine in the IDE regardless of variable values, but when I created a batch file which calls dtexec I get a failure:
Error: 2007-10-04 08:46:42.82

End Error
with the ValidateExternalMetadata set to TRUE I get
Error: 2007-10-04 09:21:35.20
Code: 0xC004706B
Source: Data Flow Task DTS.Pipeline
Description: "component "OLE DB Source" (10621)" failed validation and returned validation status "VS_NEEDSNEWMETADATA".
End Error
the most notable thing I see there is that it looks like a different ID (310) with out the validation and (10621) with it.
Any help would be greatly appreciated.

I need to check whether procedure found any matches or not. If not it has to return the column name where matching value was not found. For example, if there was no record found in the table "Addresses" column "customer" with the value @username, it should return "street". If id with value @prod_id was not found in the table "Products", the "productname" must be returned as well.
CREATE PROC sp_test
@id INT,
@username VARCHAR(50),
@prod_id INT
AS
SELECT name FROM Customers WHERE id=@id
SELECT street FROM Addresses WHERE customer=@username
SELECT productname FROM Products WHERE id=@prod_id
It is kind of check, which has to find out if users have inserted all the necessary values or not.
Thanks for any advice.

I have tried this and it doesn't work...
SELECT t1.Key1, t1.Key2, t1.Type

I've been through each step and everything looks okay. Does anyone have any idea (a) what's wrong, (b) how to localise the error or (c) get any additional information? Or do I just have to recreate the package from scratch?

I have begun my quest to become familiar with SQL 2000 table partitioning and have had some success.
I've partitioned tables according to the "rules" and guidlines of other papers and the show plans look good for all cases.
But when I went to create another demo series, I got stuck.
I've created two tables, with the appropriate CHECK constraints, and with a "union all" view.
When inserting data, it goes to the right tables.
When reading data with a where clause like:
col1=10,
the show plan shows the query getting the data from the ONE correct table.
BUT
When the where clause looks like:
where col1 between 1 and 10:
the showplan shows the query getting data from both tables, instead of the table that 1 to 10 belongs to.
Help!

Hi guys,
1) I'm about to implement SQL Table/Index Partitioning for the first time. It seems really good, no downside. Is there an "Gotcha's" I gotta be weary of?
2) My tests show a clear performance gain. Is there a performance loss in other areas?
In "Designing Partitions to Improve Query Performance" it says this:
"In this way, the SQL Server query optimizer can process the join faster, because the partitions themselves can be joined. If a query joins two tables that are not collocated or are not partitioned on the join field, the presence of partitions may actually slow down query processing instead of accelerate it."
What does that mean?
If I have:
Select A.Col1, B.Col3
from A
join B on A.Col5=B.Col6
Does that mean I have to partition A.Col5 & B.Col6 the same way else my queries will get slower?
3) Does it take up more space? Do restores take longer?
4) How much maintenance is involved?
Is there a way of automating the creation of new partitions? Or do you just create loads that you'll need in the future e.g. always have a few months' partition created ahead of time?
The "Designing Partitions to Manage Subsets of Data" article in BOL seems to indicate some manual work every month (if you have a monthly partitioning strategy).
5) Why not partition every table that has over say a million rows?
6) If I create a Yearly Partition on a table that has been around for a long time, will it automatically partition all the indexes on that table? Or do you have to re-create the indexes for that to happen?
7) Neither table can have a full-text index in a partition move. Does that mean you can't ever partition tables with full-text indexes?
8) Partitioning doesn't seem to fit well with replication. Do you have to end up choosing between the two?

I'm faced with a project that requires the caching of vacations.
Each vacation has a departure date & a price.
The amount of different vacations that will need to be cached is probably near 1 million per day.
I will then need to select the price(s) of vacations for either a single day or a date range (based on the vacation criteria).
I was considering creating a new partition (table with a date on it) every day.
This would allow me to jump into the needed table(s) based on the vacation search criteria. This would also allow me to drop tables with past dates.
I was considering running this all on 1 sql server. I was hoping I could create multiple threads for a datespan search and hit all the tables in the daterange at the same time.
Can you guys enlighten the noob on where I really need some help on this?

Hi,
I am trying to implement partitioning on a table
depending upon the fiscal_month value...
The current values are from 1-6...
Create partition function LoadDataPartitionFunction ( smallint)
as
Range for values (1,2,3,4,5,6)
-- drop partition scheme LoadDataPartitionScheme
create partition scheme LoadDataPartitionScheme
as
Partition LoadDataPartitionFunction ALL to ([PRIMARY])
CREATE TABLE Load_Data_Partition (

[Fiscal_Month] [smallint] NOT NULL,
[Fiscal_Year] [smallint] NOT NULL,

[Service] [nvarchar](100) COLLATE
) ON LoadDataPartitionScheme (Fiscal_Month)
truncate table Load_Data_old --- same schema as load_data_partition
Alter table load_data_partition switch partition 1 to Load_Data_old
-- which month's data to be moved out
alter partition function LoadDataPartitionFunction () merge range (1)
Alter partition scheme LoadDataPartitionScheme next used [primary]
-- which months data to be moved in
alter partition function LoadDataPartitionFunction () split range(7)
Select * from sys.partition_range_values
function_id boundary_id parameter_id value

65545 3 1 4
65545 4 1 5
65545 5 1 6
65545 6 1 7
Alter table [Load_Data_new] switch to [Load_Data_partition] partition 6
ALTER TABLE SWITCH statement failed. Check constraints of source table Load_Data_new' allow values that are not allowed by range defined by partition 6 on target table 'Load_Data_partition'.
Values in Load_Data_new for fiscal_month is 7
But when i try
Insert into [Load_Data_partition]
Select * from [Load_Data_new]
where fiscal_month = 7
it works fine...

hi all,
before i had a big database more than 90GB and it's growing very sharp so what i did is to create a summary database that gonna hold some aggregation and i create also three tables that gonna hold the data, on will hold the data for the last three months (very detailed information) one between 3 months and a year(less detailed) and the last one older than a year(less less detailed) these are the company requirement i'm working with.
then i transfer the data to the new tables with stored procedures.
now my question is: do i need to create a view for these three tables? and if yes how should i do it?!! cus i do not have the same columns in the three tables.

All the tables are created in datafile db1_data.mdf.
Now to improve performance I want to implement table partitioning.
Can anybody tell me howto implement it with existing strutcure.
Suppose there is table Mytable in which all update and delete actions are performed regularly.And it contains about 10,0000 records.
I want to partition the table so that it contains 5000 records.

How to partition tables in dynamic way?
I want to partion a table based on the client specific id and I want these values (client id's) to be passed dynamically to the create partition function.
I am not familiar with partitioning so it will be great if someone guides me (I am also reading some articles on partitioning, but it will be easier with some help)
The table I am trying to partition has like 80 million rows with four client's data as of now and will be more once we implement new clients.
I also think Partition will help, because before we load a client's data, we remove the data that is already out there (we flush previous qtr data before we insert this qtr data)
Any help will be appreciated.
Thanks

by default replication will replicate it to database2.table1
2. If i have database2.table1 sitting on 10 partitions
where table is partitioned on PK_x where x is divided by 10
how can i make tableX1 to be a member of database2.table1
sitting on the 7th partition. that is pk_x = 70-79

I have a table that looks like this:
ItemID TokenID WordCount

12345 3453 1
12345 546546 2
12345 242555 1
12345 556346 4
12345 346346 1
Code SnippetCREATE TABLE [dbo].[ItemTokensLink](
[ItemID] [int] NOT NULL,
[TokenID] [int] NOT NULL,
[WordCount] [int] NOT NULL DEFAULT ((1)),
CONSTRAINT [PK_ItemTokensLink_1] PRIMARY KEY CLUSTERED

[TokenID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
So this table has now reached over 22 million rows. The problem is my machine only has 1GB ram....so SQl Server tries to load up the whole table and this is ~560MB....equals zero ram for ...well anything else!
Does SQL Server load up an entire table when performing an INSERT?
Code Snippet
INSERT INTO ItemTokensLink(ItemID, TokenID, WordCount)
SELECT DISTINCT @ItemID as ItemID, t.TokenID, Count(t.TokenID) as WordCount
FROM #Tokens t
Group by TokenID
@ItemID is parameter provided
#Tokens is a temp table create with a word list
Would partitioning help here?
The table is is 80% of the time added to and the ItemID will always increase. What is the best to deal with massive tables that are inserted to frequently?
How does SQL Server decide when to load a table into memory?
TIA
