SQL Server 2008 :: No Option To Automatically Partition Table Based On Unique Values Of Column?
Jun 17, 2015
A common partitioning scenario is when the partition column has the same value for every record in the partition, as opposed to a range of values. Am I the only person who wonders why there isn't an option to automatically partition a table based on the unique values of the partition column? Instead of defining a partition function with constants, you ought to be able to just give it the column and be done. This would be particularly valuable for tables partitioned on a weekly or monthly date; when new data is added it could simply create a new partition if one doesn't already exist.
I have a question about adding a unique key column to an existing table.
what i trying to do is that: I have already created a table, now i wanna add a ID column to this table, and generate the values for ID column from 1 to the existing row number. How can I get this done?
I am pulling down out of range values from a single table on one database to a different table on a different database on a different server (one i have full access to). Basically, it looks something like this:
id1 value1 prev_value1 value2 prev_value2 date prev_date id2 value1 prev_value1 value2 prev_value2 date prev_date id3 value1 prev_value1 value2 prev_value2 date prev_date
all the "prev"'s are null. I want to do one do one query that will get me the previous values and dates for each id from the original database. how to do this.
I have a table #vert where I have value column. This data needs to be updated into two channel columns in #hori table based on channel number in #vert table.
CREATE TABLE #Vert (FILTER VARCHAR(3), CHANNEL TINYINT, VALUE TINYINT) INSERT #Vert Values('ABC', 1, 22),('ABC', 2, 32),('BBC', 1, 12),('BBC', 2, 23),('CAB', 1, 33),('CAB', 2, 44) -- COMBINATION OF FILTER AND CHANNEL IS UNIQUE CREATE TABLE #Hori (FILTER VARCHAR(3), CHANNEL1 TINYINT, CHANNEL2 TINYINT) INSERT #Hori Values ('ABC', NULL, NULL),('BBC', NULL, NULL),('CAB', NULL, NULL) -- FILTER IS UNIQUE IN #HORI TABLE
One way to achieve this is to write two update statements. After update, the output you see is my desired output
UPDATE H SET CHANNEL1= VALUE FROM #Hori H JOIN #Vert V ON V.FILTER=H.FILTER WHERE V.CHANNEL=1 -- updates only channel1 UPDATE H SET CHANNEL2= VALUE FROM #Hori H JOIN #Vert V ON V.FILTER=H.FILTER WHERE V.CHANNEL=2 -- updates only channel2 SELECT * FROM #Hori -- this is desired output
my channels number grows in #vert table like 1,2,3,4...and so Channel3, Channel4....so on in #hori table. So I cannot keep writing too many update statements. One other way is to pivot #vert table and do single update into #hori table.
Can we create the Partition on Existing Table?e.g Create table t ( col1 number(10,0), Col2 Varchar(10)) ;After the table Creation can we alter the table to partition the table.
we planning to create partitioning on existing tables. The partitioning is on date column, there should be one partition for each year.
Creating of new partitions should be automated, and also we dont have any plans of archiving old data, all we want is that new partition creation should be automated.
When you load the data into a new partition table, can it to done online without any downtime? because I have few tables that are around 250 gigs and more.
I have a comma separated field containing numerous 2 digit numbers that I would like splitting out by a corresponding unique code held in another field on the same row.
E.g
Unique Code Comma Separated Field
14587934 1,5,17,18,19,40,51,62,70
6998468 10,45,62,18,19
79585264 1,5,18
These needs to be in column format or held in an array to be used as conditional criteria.
We had a requirement that need to sum the data based on quater we will be having 12 months data in the system for an year suppose we have 12 records for 2014 year. jan month sales data should be same when we were in feb month it should sum jan+feb sales and should show in sales column whereas we were in march month it should sum jan+feb+mar sales, then same for next quater also apr month it wil be same value in may it should be apr+may in may sales value etc ....
We will be having date column values as 201401,201402,.....
How can we implement in sql sever performance should be good.
We have SharePoint list which has, say, two columns. Column A and Column B.
Column A can have three values - red, blue & green.
Column B can have four values - pen, marker, pencil & highlighter.
A typical view of list can be:
Column A - Column B red - pen red - pencil red - highlighter blue - marker blue - pencil green - pen green - highlighter red - pen blue - pencil blue - highlighter blue - pencil
We are looking to create a report from SharePoint List using SSRS which has following view:
red blue green pen 2 0 1 marker 0 1 0 pencil 1 3 0 highlighter 1 1 1
We tried Sum but not able to display in single row.
I want to concatenate the column_names with the respective values.
Create table #test1 (Id int,Name varchar(10),Country varchar(10))
insert into #test1 values ( 1,'JOHN','USA'), (2,'SAM','CANADA'), (3,'HO','CHINA'), (4,'RAM','INDIA')
select * from #test1
I have temp table with columns (Id,Name, Country). I want to concatenate column_name with their respective values; means i want column_header with every value for the column and then i want to concatenate multiple columns. I am looking for something like below:
ID values 1,NAME-john-COUNTRY-USA 2,NAME-SAM-COUNTRY-CANADA 3,NAME-HO-COUNTRY-CHINA 4,NAME-RAM-COUNTRY-INDIA
Note: This is just a sample .i am looking something dynamic because i have around 50 tables.i can do with query below but since i don't have static columns and table i am looking for something dynamic
select ID, (a+'-'+B) as Value from ( select ID,'NAME'+'-'+NAME as a,'Country'+'-'+Country as b from #test1
I've a table that has salescode(124!080) and salesamount(125.65!19.25) and I need to split the columns. Salesman(124) has commission(125.65). Here is the DDL:
USE tempdb; GO DECLARE @TEST_DATA TABLE ( DT_ID INT IDENTITY(1,1) NOT NULL PRIMARY KEY CLUSTERED , InvNoVARCHAR(10) NOT NULL , SalesCode NCHAR(80) NOT NULL , Amount NCHAR(80) NOT NULL
Deciding whether or not to use a CTE or this simple faster approach utilizing system tables, hijacking them.
SELECT s.ORDER_NUMBER, s.PRODUCT_ID, 1 AS QTY, s.VALUE/s.QTY AS VALUE FROM @SPLITROW s INNER JOIN master.dbo.spt_values t ON t.type='P' AND t.number BETWEEN 1 AND s.QTY
Just wanted to know if its okay to use system tables in a production environment and if there are any pit falls of using them ?
I don't immediately find if this is possible but hope someone can give me an answer: is it possible to make a unique constraint over 2 columns but only when 1 column has a specific value ?
Example: table (tableid, instancetype, instancename, ..) instancetype can be A or B if it is A then instancename must be unique but for B instancename is not unique as these are copies from A
only solution I can think of is to make a trigger on an insert to check what the instancetype is and do a select to see if the name already exists in the table or not..
are there other solutions to make a constraint like this ?
Below is a XML column data. How to get the Id and respective Names for "Case Manager" Dropdown ONLY in SQL server 2008. I don't want to get anything related to "Intake Staff" drop down.
My question is: How can I insert a row for each unique TemplateId. So let's say I have templateIds like, 2,5,6,7... For each unique templateId, how can I insert one more row?
I created a query that got the following result. But I expect to get the structure like, care_nbr, cust_nbr,legal_name, address_type=physical address, addr_line_1, addr_line_2, address_type-primary address, ddr_line_1, addr_line_2. That means I only need primary and physical address, and expect them to show in a row to each care_nbr. How to perform that?
I'm trying to load data from old SQL server 2000 to new SQL server 2014. I need to do a checksum to check if all the source data is loaded in the target database(SQL server 2014). I've created the insert statement for the same which works. I need to use checksum to make sure all the source rows are loaded in the target table. I haven't done checksum before.
Here is my insert statement:
INSERT INTO [Test].[dbo].[Order_tab] ([rec_id] ,[date_loaded] ,[Name1] ,[Name2] ,[Address1] ,[Address2]
I am using Access 2007 and I have 10 columns of data.
I am trying to select all the data from all 10 columns where the first column's data returns only the Unique values and the other columns return all the data from the row that is returned from the first column.
But that returns all the data in the table and all values in the Sorter column with duplicates because each row has distinct data.
I am trying to return unique values from [SFR Rates All].Sorter (the first column) and all the data from the other 9 columns that are contain the row with the unique value in Sorter.
I know that I am missing something basic but well, I can't figure it out.
I have a table Tbl1 which has 7 columns.This table will be my base table.By using our current application version ,i'll be creating record for Client1. Col1 will have value that application will generate(id).Then i'll be creating Tbl2 with same columns.Then i'll be creating same record for Client1 again ,using our new application version .Col1 will have different (id)value.I would like to compare the rest of the columns if there is any discrepancy caused by new version(columns Col2 -Col7).If there are same ,don't show me anything.
I am working with a vendor application called Cisco Unified Attendant Console - it operates on a Windows server with a SQL express database. The CUPs function of the application needs to reference a "contact" field with only the user portion of the contact's email address - generally, the contact's User ID will match the user portion of their email address, however, for this customer it does not (they use the employee number as the User ID and firstname.lastname as user portion of the email address.
Writing a script to accomplish the following:
The dbo.Contact_Properties table of the ATTCFG database has the following fields that we can work with:
- First_Name - Last_Name - Email - User_Field_2 - Contact_Unique_Ref (appears to be the field that ties all other contact tables together ?)
Is it possible to create a script that could run daily to either, combine the First_Name and Last_Name fields (with a period between) and populate the User_Field_2 field for each user, or populate the User_Field_2 field with everything before the @ symbol in the Email field for each user?
Also, by default the servers that this application is installed on does not have SQL Server Management Studio installed - is it possible to accomplish with PowerShell script triggered from the Windows Scheduler?
(idAuxiliarPF(BIGINT+PK), pf(BIGINT+FK), Data(DateTime), Descr(NVARCHAR))that has aprox. 50k rows.
I need to create a partition of the data to join to another table, the query that i have:
SELECT ROW_NUMBER() OVER (PARTITION BY pf ORDER BY Data DESC, idAuxiliarPF DESC) AS RN, pf, Data, Descr FROM dbo.PFAuxiliar WHERE Data <= GETDATE()This query takes around 40 seconds to return the results
If i remove the Descr column, the query it takes no time.
SELECT ROW_NUMBER() OVER (PARTITION BY pf ORDER BY Data DESC, idAuxiliarPF DESC) AS RN, pf, Data FROM dbo.PFAuxiliar WHERE Data <= GETDATE()I have two indexes, Clustered (idAuxiliarPF), NONClustered(pf).
I've got a large table (3mil records) with a number of columns, but currently no way to refer to any individual column. I therefore need a primary key, but does anyone know of a SQL statement I can use that will create a column (say, ID) that is automatically filled with an incrementing 'counter'? Or, instead, how can I set unique incremental values after first creating the column?
I need to write a select query that gets the values of all columns but only returns unique sites because some sites are load balanced across several servers and where this is the case I don't want the site to appear multiple times in the list.
I need to create a function that replaces the data in a column with an 'X' based on the LEN of the data in the column. I created one that does a replacement, but it fills the column based on the max data length, and not the current length of the string or integer. An example of what I'm trying to accomplish.
Original data in a varchar(30) column: thisisavalue thisisanothervalue thisisanothervalueagain shortval
replaced with xxxxxxxxxx xxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxx xxxxxxx
My current function is replacing the data like this: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
I have a table with PO#,Days_to_travel, and Days_warehouse fields. I take the distinct Days_in_warehouse values in the table and insert them into a temp table. I want a script that will insert all of the values in the Days_in_warehouse field from the temp table into the Days_in_warehouse_batch row in table 1 by PO# duplicating the PO records until all of the POs have a record per distinct value.
Example:
Temp table: (Contains only one field with all distinct values in table 1)
The objective is to identify orders where an order fee has been applied incorrectly. I have multiple orders per customer, my table contains an orderID and a customerID. Currently if the customer places additional orders before the previous orders have been closed/cancelled, then additional fees are being applied.
Let's say I'm comparing order #1 to order #2. I need to identify these rows where the following is true:-
The CustID is the same.
Order #2 has a more recent order date.
Order #2 has a FeeDate Before the CancelledDate of Order #1 (or Order #1 has no cancellation date).
So in the table the orderID:2835692 of CustID: 24643 has a valid order fee. But all the subsequently placed orders have fees which were applied before the first order was cancelled and so I want to update the FeeInvalid column with a 'Y'. The first fee will always be valid.
I think I understand why the code I am trying doesn't achieve the result I want but I can't figure out how to write it correctly. Below is one example of code I've tried and also code to create the table and insert some test data.
update t1 SET FeeInvalid = 'Y' FROM MockData t1 Join MockData t2 on t1.CustID = t2.CustID WHERE t1.CustID = t2.CustID AND t2.OrderDate > t1.OrderDate AND t2.FeeDate > t1.CancelledDate CREATE TABLE [dbo].[MockData]( [OrderID] [float] NULL,
