SQL Server 2008 :: How To Add More Partitions To Existed Table
Dec 31, 2011
I have a table that contains records of transactions with ID column is primary key
I use partition follow ID column, each partition have 1 million records.
CREATE PARTITION FUNCTION [pfTBLTRANS_ID](int) AS RANGE LEFT FOR VALUES (1000000, 2000000, 3000000, 4000000, 5000000, 6000000, 7000000, 8000000, 9000000, 10000000)
CREATE PARTITION SCHEME [psTBLTRANS_ID] AS PARTITION [pfTBLTRANS_ID] TO ([GROUP01], [GROUP02], [GROUP03], [GROUP04], [GROUP05], [GROUP06], [GROUP07], [GROUP08], [GROUP09], [GROUP10], [GROUP11])
But now I have more records with IDs that are greater than 11.000.000. So how can I add more partitions to this table ?
I am restoring a database with 10yrs worth of data which have monthly partitions but i would like to keep only 5yrs of data after the restore is done, what is the best/faster approach to delete the 5yrs data without deleting the partitions as that may cause the db in accessible.
We have a huge table with around 250 million records and have implemented SQL server 2005's new table partitioning feature. Now the data seems to be evenly spread across 20 different filegroups ( each 5 GB approx ) for the same table that was occupying 100 GB itself in the PRIMARY filegroup earlier.
Still the query response times have not come down drastically but we could see a good improvement in the execution plans now.
WE ARE USING RAID 5 IN OUR PRODUCTION ENVIRONMENT. ANY IDEA / THOUGHT ON HOW TO PLACE THE PARTITIONED FILEGROUPS AND THE LOG FILES IN THE RAID 5 (BTW , I'm very new to RAID concepts , any detailed instruction would be helpful ).
For my work I am now learning Sql server 2005 and I have been given a database that has been set up by someone else to work with. It is my job to get the database ready for use in reports.
My problem is that the current database has one huge table with almost 8GB of data. The table contains data from 2004 to present (and growing) from 14 different countries. The reports we use are mostly per country, but we also want to compare the 14 countries to eachother for say, whole 2006. At the moment the table is stored in one single file instead of using partitions.
I believe partitions can give a good performance boost when running the queries. But how do I do this? Currently the country codes are just plain text, can they be used for partitions?
We have a very huge database that stores 12 years of data(120 Million records). But our application mainly accesses past 3 years data i.e , the queries would scan the 120 million records even when it actually has to scan 30 million records alone (for 3 years).
Since few other important applications needs access to all the 12 years data, we are in a position to have 12 years data in the same database.
Right now we are looking for an approach that would help us to efficiently access the 3 years data alone and boost the performance.
1. Will SQL server table paritioning help in this scenario ?
Or
2. Indexed views would help us ? Is it possible to create indexed views based on year range and access the views in the stored procedures ?
Hi guys , assuming right now I already create partition function (PF_Date) and partition scheme (PS_Date). Let say I would like to implement the partition on the existing tables ( eg: transaction table which is in PRIMARY filegroup), how am I switch it from PRIMARY to PS_Date ? Is it I have to re-create the particular table then only able to put in the partition scheme? Hope can get any assistance here. Thanks alot.
First off, I'm not very familiar with SQL Server. I need some guidance on what the best path to take is for this as it may not even be table partitions.
I have a huge table (155 million rows) and it's gotten so large than I can't even delete a large set of rows from it (i.e. delete everything older than 6 mo, which would be ~100 million rows). When trying to run a delete like this, it just goes for a LONG time and then just eventually runs out of memory.
The current data in this table can actually be completely cleared out soon (after Feb 1st) and I plan to do this with TRUNCATE TABLE, or just DROP and recreate. Once I do this, I want to create a way to keep this table moderately sized so it never grows that large again and it seems table partitions may be the way to go for this?
I'd like to keep the last 6mo of data in it (I have a datetime column to keep track of this). Anything older I'd like automatically removed. Can I do this with table partitioning? Create 6 partitions that store the 6 most recent months of data and everything older automatically gets dropped off?
If not partitions, what do you suggest to keep this DB modest size?
SQL 2014 I've inherited a db that has several partitioned tables. They are partitioned by month. We're approaching the last partition, 11-30-2015, so we need to extend the tables. My question is how do I do this? There are Partition Schemes and Partition Functions setup at the db level. I've figured out how to ALTER those. Next I go to a table that I know is partitioned, right-click Storage and select Manage Partitions.
My only option is to "create a staging table for partition switching". Not knowing what switching is, I'm not sure if this is what I want to do. All I want to do is add new partitions to the table - and remove some of the old ones since they are empty due to archiving of data.
So, what is the proper steps to adding new partitions to a table that is already partitioned?
I have 3 columns. I would like to update a table based on job_cd and permit_nbr column. if we have same job_cd and permit_nbr, reference number should be same else it should take max(reference number) from the table +1 for all rows where reference_nbr column is null
I'm inserting from TempAccrual to VacationAccrual . It works nicely, however if I run this script again it will insert the same values again in VacationAccrual. How do I block that? IF there is a small change in one of the column in TempAccrual then allow insert. Here is my query
INSERT INTO vacationaccrual (empno, accrued_vacation, accrued_sick_effective_date, accrued_sick, import_date)
I have table having around 100 million rows.Everyday we have an ETL process in which table will be trucnated and relaoded. Will creating a partition on the table increase the inserting speed?
how to set up the partitions.I have a transaction table with 50 million records that's very hard to query. it holds data for the last 4 years but the application only ever looks at the last 6 months so i believe this is and ideal candidate for partitioning.
Would it be better to
1) create a partition based on each year for all data so would have a 2015, 2014, 2013, 2012? 2) create 1 partition based on month for this years data then 3 based on year so would have jan,feb,march,april,may..., 2014, 2013, 2012
For 1) would you have to perform some maintenance at the turn of each year for accommodating the next years data. For 2) although this would give better performance as query's are mostly in the last 6 months wouldn't this have more maintenance to move month data to year partitions come the turn of the year and then create the next years months partitions.
I created am inventory table with few columns say, Servername, version, patching details, etc
I want a tracking of the table.
Let's say people are asked to modify the base table and I want a complete capture of the details modified and the session of the user ( ) who (system_user) is actually modifying the details.
I am trying to insert bulk data into main table from staging table in sql server 2012. If any error comes, this total activity is rollbacked. I don't want that to happen. I want to know the records where ever the problem persists, and the rest has to be inserted.
I have a scenario where I have to Update a table with date when there are new records in another table
For example:
I load ODS table with the data from a file in SSIS. the file has CustomerID and other columns.
Now, when there is new record for any customerID in Ods, then Update the dbo table with the most recent record for every CustomerID(i.e. update the date column in dbo for that customerID). Also Include an Identifier that relates back to the ODS table. How do I do this?
I am looking for information/suggestions in regards to portioning data across a large SAN. The database is several TB in size, and we are looking to partition the data on a date so that the current data is always the fastest available and history can be set as read only but still be available.
If the server has 8 drive letters how can I ensure that the 4 data drives are stripped across the most physical drives for the most through-put??
Are there any specific questions I need to ask the server technicians?
I have two table 'Cal_date' and 'RPT_Invoice_Shipped'.Table cal_data has column month_no, start_date and end_date. And table RPT_Invoice_Shipped has columns Day_No, Date, Div_code, Total_Invoiced, Shipped_Value, Line_Shipped, Unit_Shipped, Transaction_Date.
I am using below insert statment to insert data in RPT_Invoice_Shipped table.
insert into [Global_Report_Staging].[dbo].[RPT_Invoice_Shipped] (Day_No, Date, Div_code, Total_Invoiced, Transaction_Date) select , CONVERT(DATE,Getdate()) as Date, LTRIM(RTRIM(div_Code)), sum(tot_Net_Amt) as Total_Invoiced, (dateadd(day, -1, convert(date, getdate()))) from [Global_Report_Staging].[dbo].[STG_Shipped_Invoiced] WHERE CONVERT(DATE,Created_date )=CONVERT(DATE,Getdate()) group by div_code
while inserting in column Day_No in RPT_Invoice_Shipped table, I have to use formula (Transaction_Date-start_date+1) where Transaction_Date from STG_Shipped_Invoiced and start_date from Cal_date table. I was using datepart (mm, Transaction_Date) so it gives month_no, and this month_no we can join with month_no of Cal_date table and fetch start_date from Cal_date table, so that we can use start_date for formula (Transaction_Date-start_date+1).
But I am getting difficulty to arrange this in above query. how to achieve this?
I am trying to replicated table A into table B withing the same server and the same database.
I am getting an error message when trying to configure the subscription: You have selected the Publisher as a Subscriber and entered a subscription database that is the same as the publishing database. Select another subscription database.
If I run an UPDATE query on a table which is partitioned by the column I am updating - will the records be moved to another partition?
ie. I have a table where Historical bit column marks whether a particular record should go to Partition1 (=0) or Partition2 (=1). Now, I update a record in that table and change the Historical column value from 0 to 1. What happens with that record?
I have a situation where a person, who created our DW, likes to go in and change table name. This person had no prior SQL xp and is at a higher level then me in the company. I need to know whenever somebody changes a table name I get notified, with the old table name and the new table name. This can be either set on the server level or the DB level. I would like to use the policy management but cant find the way to do it.
I am working on SQL SERVER schemas using a plug-in in SQL developer itself now my requirement is to generate DDL for a table which is part of SQL SERVER schema...
1. Is there any way to get the Table Row Count if we are not maintaining the count.
2. This is for Update statistics
a. Should we run update statistics in our database for all the tables? The database is highly transactional.
b. How should i calculate the sample size that will suite for all the tables.
There are some tables which gets reindex, this we will ignore. We have a job, which reorganise some tables. Now the decision need to be taken what table should we update statistics to:
Production and development servers are on different domains and they do not trust each other. How do I import data from the table t1 from a database db1 in production and load it into table t1 inside database db1 in development?
I have an sql server table which serves as a criteria table for my sql server query.
i wish to update the sql server table from the excel worksheet. The intention is to allow the end user to change the values in a specific column in the sql server table via excel.
