How To Archiv Part Of The Table Information Based On The Timestamp?
Jul 25, 2003
In my database I want to archive some rows based on the time stamp. I read that horizontal partitioning will do that. This partitioning will insert the rows from the table into some other Database - Tablename. In retrivng those rows back I need to issue separate queries and UNION the result set. Is this way is correct or there any better ways to do this? If it is I have another question. If I add a new column to the table I partitioned, what will happen to the table that I stored in other Database. Is that going to add this new column too?
If possible please give me a sample code or queries to partition the database.
What I need to do is merge the two tables into a single table based on the matching timestamp:
timestamp, servername1, servername2 as headers then values under "1/1/1-1:10:1" , "10" , "10" - as an example "1/1/1-1:20:1" , "20" , "21" - as an example "1/1/1-1:30:1" , "1" , "5" - as an example
Powershell or MSSQL 2008 queries work.
I have a powershell script atm that can create the table and then throw it back into the database but its very slow because of the amount of records.
The table is for some performance stat collection app.
Table #1 records a timestamp, the servername (which is the same over and over in the table) and the value of the performance object. Table #2 is the same collection but for a different server.
The layout in the database is terrible but this is what I get to work with.

where name comes from the info table, and number of items comes from the store table.
Query something like:
show the total number of items for all those users (in the fashion Name, Number of items)from the store table, for all those whose level=something and base=something in the auth table.
For example,
if there are 10 users whom match level=something and base=something in the auth table,
What I want displayed is: ------------------------ Name Number of Items ------------------------ user1 10 user2 15 user3 20 .... user10 30 -----------------------
which if broken up is: select name from info where aid=X select count(*) from store where aid=X ..
for all those whose base=something and level=something from auth.
Is there a way to extract the date part (11/27/2012) of a datetime/time stamp column (11/27/2012 00:00:00.000) and keep it in a date format?
The code i have below extracts the date part of a timestamp column and converts it to a char field. This becomes a problem when I joing the resultant table with a SAS dataset which contains the same column but is in a date format. The join process generates an error saying the column is in different formats.
I have a business requirement to build a tabular data model, where I need to mask information of other Agents from a given Agent but I still need to show the overall sales of the given product.
For eg: IF an Agent is in APAC region he should see APAC region sales and also should be able see the sales of the same product in other region without knowing region specific break down.
For Agent "Tom" in APAC region, the numbers will look like this APAC_Sales = 100,000 Other_Sales = 500,000
And if "John" is in NA region, then the number will look like this for him
NA_Sales = 200,000 Other_Sales = 400,000
I wanted to create "Roles" based on the Region, so all the agents belong to "APAC" region will have same view as Tom and "NA" region agents will have John's view.
I am trying to write a query that will be able to select different segments of data based on spelling of the last name.
For example, in my database of name information, I need to select anyone whose last name starts with 'AAA' to 'EJJ'
then need to select anyone whose last name starts with 'EJK' to 'JAE' and so on...
I have tried using LIKE and some other methods with the > operator, but I can't get it to work. Does anyone have any suggestions or ideas on how to select data based on the alphanumeric characters this way?

I have a transaction table having about 40 crore rows in source. It don't have timestamp and unique key columns. It have only Bill_month and Bill_Year columns. Actually for loading this table into staging I have added a new datetime column by adding default bill_date as 01. Then
* First we delete last 3 month data from staging tables. * Get last 3 months data from source table. * Load that 3 months data from source to staging table.
We do this because we only get update for last three months data. Now I have to include this transaction table as Fact table in DW. What will be the best practice for loading the fact table by picking data form staging table. Also we have to look up with dimensions for Foreign Keys.
* Should I implement the same method of deleting last 3 months records and loading them again.
I am populating oracle source in Sql Server Destination. after few rows it fails it displays this error:
[OLE DB Destination [16]] Error: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005. An OLE DB record is available. Source: "Microsoft OLE DB Provider for SQL Server" Hresult: 0x80004005 Description: "Invalid date format".
I used this script component using the following code in between the adapters, However after 9,500 rows it failed again giving the same above error:
To convert Oracle timestamp to Sql Server timestamp
If Row.CALCULATEDETADATECUST_IsNull = False Then
If IsDate(DateSerial(Row.CALCULATEDETADATECUST.Year, Row.CALCULATEDETADATECUST.Month, Row.CALCULATEDETADATECUST.Day)) Then
dt = Row.CALCULATEDETADATECUST
Row.CALCULATEDETADATECUSTD = dt
End If
End If
I don't know if my code is right . Please inform, how i can achieve this.
Is there any reason to have a row that is the PK/Identity and a rowthat is datatype Timestamp in the same table?Does this in any way help speeding up row updates?Thanks,lq
I've heard that in Oracle, tables have an implicitly column that stores the last modified timestamps for each record. Using this timestamp i can find out all the newly inserted/updated records in a table. Do we have something similar in SQL server. Or is there a method to find out newly inserted/updated/deleted records ?
I want to make a query, stored procedure, or whatever which will only display the primary key where there does no exist a foreign key in linked table.For example. If I had two tables with a one to many relationship.A [Computer] has one or more [Hard Drives]. I want to select only those computers which do not have a Hard Drive(s) associated with them. That is, show all computers where the Computer_ID field in the [Hard Drives] table does not exist. This seems simple but I'm drawing a blank here.
how you code to get a timestamps to a temp table.ex. select date from clock where name='name' and nbr='10';I want this data to be in my temp date table..
I have SSRS 2005 SP2 configured to work in Sharepoint integration. Everything works fine except that I am not able to programmatically change any property of report viewer web part (instance) that I have added on on home page of my sharepoint site. I can do same thing via sharepoint UI but not through program. When my programs runs it fetches all web parts been added on home page, then I need to iterate through each one and find report viewer web part. While iterating, as soon as I arrive to report viewer web part it is named as "Error web part" with error message as "Windows SharePoint Services cannot deserialize the Web Part. Check the format of the properties and try again"
If someone has a solution, please respond at your earlist.
There is a simple SQL table ("mytable"). Say, it has 100 rows and 5 columns. One of the columns (say "time") contains timestamps across the whole day and the data in this column has the following format: hh:mm:ssAM/PM. So, the table looks like this:
time var1 var2 var3 var4
12:00:01PM value ... 12:00:05PM value 12:00:08PM value 12:00:20PM value 12:10:12PM value ...100 rows
How to create simple SQL request for extracting data between any 2 timestamps? For example, I need sub-table of the initial table containing all data values between 12:00:05PM and 12:00:20PM:
time var1 var2 var3 var4
12:00:05PM value 12:00:08PM value 12:00:20PM value
I have been provided with a table where one of the columns is of TimeStamp data type. My question is how to insert and update data in this column through my SQL Statement? When I run my SQL statement, it gives me an error with this column name in the error.
Im trying to insert the values from this query into a table, so I can later check the history of memory usage:
SELECT [total_physical_memory_kb] / 1024 AS [Total_Physical_Memory_In_MB] ,[available_page_file_kb] / 1024 AS [Available_Physical_Memory_In_MB] ,[total_page_file_kb] / 1024 AS [Total_Page_File_In_MB] ,[available_page_file_kb] / 1024 AS [Available_Page_File_MB] ,[kernel_paged_pool_kb] / 1024 AS [Kernel_Paged_Pool_MB] ,[kernel_nonpaged_pool_kb] / 1024 AS [Kernel_Nonpaged_Pool_MB] ,[system_memory_state_desc] AS [System_Memory_State_Desc] FROM [master].[sys].[dm_os_sys_memory]
What I'm missing is a way to insert the current timestamp every time I insert to the table.My plan is to use the insert into command.
Hi, There's a nullable Timestamp data type column in all tables in Sage SQL database. When using Insert SQL query add a new record, with a NULL for the Timestamp column, into a table it seems alright. When opening the table it shows the inserted data in the Timestamp column is Binary. But when reading the record by Sage program there's an error message as the following: 'Fractional truncation: table scheme.opheadm unique_no 24969592 1'. Any idea what the problem is? Thanks, Yabing
I have a table with a column named measurement decimal(18,1). If the value is 2.0, I want the stored proc to return 2 but if the value is 2.5 I want the stored proc to return 2.5. So if the value after the decimal point is 0, I only want the stored proc to return the integer portion. Is there a sql function that I can use to determine what the fraction part of the decimal value is? In c#, I can use dr["measurement "].ToString().Split(".".ToCharArray())[1] to see what the value after the decimal is.
I created a SSIS package and creating a derived column named: Date...set datatype as DT_DBDATE....I do not want the timestamp on date...then I want to load this Date into a SQL server database table, with datatype of datetime, but it will load here with the timestamp which I do not want. Any ideas? I did change datatype of the SQL Server Destination datatype to DT_DBDATE but it will change it back to DT_DBTimestamp. thx
I have used the Microsoft code below to create a link to SQL server from access. I am using DAO not ADODB. Someone said that I should use dblib instead of ODBC in the connection string below in order to get the connection to work.
Does anyone know the correct syntax for OLE DB connection string and can it be used with DAO? I am getting an error "ISAM path not found"?? Seems I have wrong connection string syntax?? Please advise.
Thanks again for your help.

Tell me please how can I make a foreing key constraint for a table using from another not all primary key or not all data. For example, I need to link a table "subject" with primary key "dscp_num, depart" using depart as a foreing key. But there is no table with such primary key, there is only table "codif_values" where selecting records by condition "codif_num = 1" gives the relation with necesary primary key to link. Also I need to link "subject" table as a primary key table with the table "ses_curr". But this table doesn't include "depart" field. It includes field "reg_num" that is a primary key in table "students". This table include field "stgroup" as a foreing key for table "groups". The last table includes "speciality" field that is a foreing key for table "specialities". And only this table includes "depart" field. Tell me please how I can make a foreing key constraint for table "ses_curr" by table "subject".
I want to add a new column in a table. In this column I want to include a Total Value. This Total Value exists already for dates after Sept 23, 2013. For dates before Sept 23, 2013 the total can be calculated using the following math:
Total = Total(t-1) - (Resource_Name1-Resource_Name1).
The Resource_Name column contains the Total field (after Sept 23) as well as the Resource_Name1 field. There is a third column called Direction which contains the values injection or withdrawal. The Resource_Name1 differes in value depending on whether it is injection or withdrawal. How do I create a new column with Totals for the full data set?
I have a huge question, it's for my job im doing now. I have a table with the name TWO.dbo.SVC06105. I want to be able to take the word "TWO" and put that into a variable. I know this doesn't look correct, but I want to be able to do something like this:
DECLARE @GPNAME CHAR(100) SET @GPNAME = 'TWO'
SELECT * FROM @GPNAME.dbo.SVC06105
I know the SELECT statement isn't correct, but I hope that you guys understand what i'm trying to do through this example. BTW, I am new to this team so nice to meet you all. L8er
I want to join this table with itself on reg. no. But not all the rows in table must be joined.
But for example, rows with load_date 01-07-2015 to be joined with rows with load_date 02-07-2015. And the rest of the rows should not used in join (for example, rows having other load_dates)
Hi, In my Sql Sever i have added one Database "Devtools", by restoring it from .bak file. Now In my asp page I want to Display a Datagrid with data from a table "Devices". I want to Generate the Gridview dynamically. The columns in the table are dynamic they are not constant so I want to generate my Gridview dynamically. So I want to get the columns info of the table and based on that I want to dynamically add the columns to the table. So how to get the info of the table first. Is there any query where i can get the table info
