Integration Services :: Load Incremental Data Into Fact Table When Source Table Not Have Timestamp And Unique Key
Sep 24, 2015I 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.

Automatic Purge Of Transaction Log Data?
Jan 25, 2007Hello,
I have a database that I am setting up in SQL Server 2005. Initially, I am doing very large imports of data. Every time I run an import, I am having the increase the size of my transaction logs, and now they are approaching 2 GB. Should these be purging themselves? I have to keep increasing the max size of the log so that I can get my data in. While this will work for now, it is not a long term solution, because I can see the log size growing quite large and the amount of space on the server obviously isn't infinite. Is there a setting that I can change so they will automatically purge? If not, how do I purge this information myself?
Thanks so much!

Integration Services :: How To Load Data From CSV File To Dynamic Table

View 8 Replies View RelatedMassive Bulk Delete / Data Purge Problem
Jan 28, 2008I've got a large MS Sql Server 2000 database that has 15 indexes, with roughly 180 million rows representing 240 GB worth of data. Due to the massive size of the database we are trying to purge it down to a smaller dataset, about 40 million rows, in order to speed up the query performance and to be able to defrag the indexes (which are 30-50% fragmented). To complicate the matter, this table is also a publisher in a transactional replication setup, with one subscriber. Also, the system needs to be up constantly so I'm only allowed about a 3-5 hour period to take an outage a week.
So far I've tested several methods of delete following all best practices (batch deletes, using indexes in delete's where clause), and have come up with deleting/commiting 500 rows at a time. The problem is that it still takes 3-4 seconds to delete this many rows, on a 8 GB RAM, 4 processor machine that is not currently used or replicated.
I'm at a loss on a way to pare down the data with a delete as the current purge script will take 7 hours a day for about 3 months. Another option I'm considering is to do a truncate and copy the data back over from the replicated database, but again this has its own set of problems, i.e. network latency and slow inset times. Yet another option would be to create a replica of the table on the production db, copy the data to it, then rename the table.
Any one have experience with purging such a massive amount of data? Any help would be greatly appreciated.

Integration Services :: SSIS Data Transfer Says Rows Copied But Count On Table Is Less?
Sep 18, 2015I've a SSIS 2008 parent/child package solution to manage data transfers between two different data sources, so we can copy multiple tables and capture how many rows were transferred and duration for each transfer. This solution was working fine up until last week, when I made some changes to allow the package to perform a source count using standard SQL determined by an expression, or SQL provided from configuration tables, I also changed the package to Truncate or not the destination table, again controlled by configuration settings in a table. The child packages which perform the data flows have not changed!
The day after the controlling package promotion to live, I saw the bizarre behaviour of the Package log stating all rows transferred, but the actual table counts were not what the log stated, see attached file. The package solution works ok on other servers and was ok in DEV, but there were less tables and rows transferred.Re-running the package gave the same errors, but on some of the same tables and some different ones.
As it is the child packages doing the transfers and nothing has changed in them. I cannot see how the log would be able to say all rows are transferred and yet not all of the rows are actually moved?
Process output - where you can see counts and log Table transfer controller (as txt not dtsx)
An example of the data transfer child packages (as txt not dtsx)When I set the ExecuteOutOfProcess = True the package worked fine, unfortunately, this is not a good solution as SSIS 2008 does not tidy up the Dtshost.exe processes it starts and I'd be left with a memory issue after a very short time, we transfer hundreds of tables each day. ( I could write a .net script in the controlling package to kill the child processes, but that would still have hundreds of processes running before I could end them, as we have three parallel streams to allow a bit better performance.
Integration Services :: Dataflow Task Read CSV File And Insert Data To Table
Apr 29, 2015I've a dataflow task on For Each Loop container at control flow of SSIS package. This For Each Loop container reads the CSV files from the specified location one by one, and populates a variable with current file name. Note, the tables where I would like to push the data from each CSV file are also having the same names as CSV file names.On the dataflow task, I've Flat File component as a source, this component uses the above variable to read the data of a particular file.
Now, here my question comes, how can I move the data to destination, SQL table, using the same variable name?I've tried to setup the OLE DB destination component dynamically but it executes well only for first time. It does not change the mappings as per the columns of the second CSV file. There're around 50 CSV files, each has different set off columns in it. These files needs to be migrated to SQL tables using the optimum way.
Which is the best way to setup the Dataflow task for this requirement?Also, I cannot use Bulk insert task here as we would like to keep a log of corrupted rows.
Integration Services :: Check Table For Existing Record Before Data Flow Task
Jun 1, 2015Using SSIS 2012 (within Visual Studio) on Windows 7.
Before allowing my Data Flow task to fire, I'd like to check the target table (OLE DB Destination) for a specific date value in a specific field. I've seen how the Lookup Task is commonly used to check for dupes before inserting, but I'm not able to use that method because the data value I want to search the table for is contained in a Global Variable (let's say "MyVariableDate").
Is there any way to check for any records in a target table where Date1 = MyVariableDate (i.e. scanning the entire table for any occurrence of MyVariableDate in the Date1 field)?

SQL 2012 :: Count Records From Each Separate Data Table Corresponding To Feed
Nov 5, 2014I have 1 table that is just a list of feeds. A, B, C, D etc (15 rows in total) and each feed has other information attached to it such as Full name, location etc etc. I am only interested in the Feed column.
Each feed then has a corresponding data table which contains a list of records. Eg Feed A data is contained in TableA, Feed B data is contains in TableB and so on.
Basically what I need is a combined table that shows the list of Feeds in the 1st Column ( So A, B, C, D…..) and then a second column which counts the records from each separate data table corresponding to that feed.
So the end result would look something like this:
Feed------No of Records
A----------4 (from TableA)
B----------7 (from TableB)
C----------8 (from TableC)
D----------1 (from TableD)
Possible?

SQL Server 2008 :: Store Long Values To Be Used In (IN) Statement In Separate Table?
Jul 14, 2015I have several reports that are looking for a code within a certain set of codes or ranges. The specific list of codes to be including is determined by the end user. Currently my "IN" statement can be a hundred lines, listing several ranges, lists of specific codes, etc. I am constantly getting asked what codes does it include, is this code included, etc. Sometimes they'll give me a printed 10 page list of codes and want me to compare to what I have included in the report. Not ideal in the slightest.
What I'd like to do is have a table or a file of some kind somewhere where the end user can view the codes contained, add new ones, and delete ones they no longer want. Then I'd like to be able to just reference that file in my IN statement. Leaving the responsibility of listing the correct codes on them.
Produce Data -&&> Store In Table?
Sep 4, 2007Hi!
I'm quite new to T-SQL and is about to build a small reporting db using SQL.
Most of the data I can move with normal INSERT INTO ... SELECT, but there are some tables that I want to
produce using T-SQL. For example I want to build a Date table like..
Date
Year
Quarter
Month
WeekDay
...
With some precalculated values for each date.
I've searched the forum but have not found any information on how to produce table contents in a good manner. I would appreciate if someone would have the time to point me in the right direction. I do not want to do this by code in my application.
My first thought is to use some kind of Insert Cursor in a While loop...
Pseudo:
---------------------
declare cursor ex for 'Insert table ... '
while
begin
(produce data)
insert data
end
close cursor
---------------------
While browsing the net I've got the feeling that you use cursor less in SQL Server than in other db-engines...
Have a nice day!
