Hi,
I am performing data migration from a legacy sql server (2000) to a new one (SQL 2005). I am using SSIS packages to perform the migration.
The source legacy sql server is a live machine (used by the customer). Therefore, during the data transfer there would certainly be new records inserted/updated/deleted on the source legacy sql server.
Now, after the migration i wish to migrate the delta to the new sql server. how can i do this ?
Does SSIS have any provision to take care of it ?
Hi ,
i'm new to this platform and am wondering if there is an easy way to identify ADDs changes and deletes between two tables - or whether i will have to do a ror for row comparison using the business key?
Any suggestions would be greatly appreciated..
thank you George Bassili
Suppose a database server and client are separated by a low bandwidthlink such as DSL, and the client repeatedly issues a query for, say, acurrent product list.Suppose the product list is large, but only a handful of entries havetypically changed between queries. It would be nice if only the changesfrom last query to current one could be sent, saving bandwidth.Is there any way to do this?Thanks,--"Always look on the bright side of life."To reply by email, replace no.spam with my last name.

1. What is the difference between modify and modify_attribute? How does modify_attribute works at attribute level? Is it only for multivalued attributes?
2. Rather than having an extra table for Delta. If we would use the prime table itself with an extra field acting as a flag (0/1) (0=Prime Record, 1=Delta Record) and generate the delta view according to the flag. Would it be fine or we should have a different delta table only?
I'm working on a program that reads in zip codes and then does some checking on them. Occasionally, the end user typos or transposes digits. It's easy enough to identify bad zip codes, but I would like to offer up a single recommendation. The problem is that there are often multiples to choose from. Is there a function or has anyone tried to figure out the delta between two strings?
Thanks
I need to get the replacement records between the 2 tables. I have table A and table B with same structure. I have 5 fields. Table A has 50,000 records and table B has 20,000 records. I have fields id , name, address,meter_flag,end_Date.
Some of the records in Table B are just replacement records of table A. I mean for example I have records like this in Table A
id name address meter_flag end_date
23 john 1201 salt lake dr no 2011-12-28
24 tom 1222 gibson ln yes 2011-12-16
25 alex 1334 qayak dr no 2011-12-17
In Table B
23 john 1344 mc kinney st yes 2011-12-18
24 tom 1222 gibson ln yes 2011-12-16
56 gary 1335 pruitt rd no 2011-12-18
25 alex 1334 qayak dr no 2011-12-17
So here in Table B i have an update for john with id 23 in table A in address field and meter_flag has changed to yes. There is new record with id 25 in table b but that is not in table A. so I need to find all these difference records by querying these 2 table
Currently through my stored procedure, I am pulling the data from my source systems in the way Daily Truncate and loading the data in to my database table. Currently my query looks as follows,
SELECT
a.col1,a.col2,b.col3,b.col4,c.col5
FROM
a
left outer join b ON a.col1 = b.col1
left outer join c ON b.col1 = c.col1.
Now, I want to change the above one to delta process(I have updateddate field in all the tables). The requirement is any of these 3 tables has updateddate = getdate() then i need to take "a.col1,a.col2,b.col3,b.col4,c.col5" columns and push to destination
table.
I think usually delta process means we will use to consider the key table, in that table if there is an updated record will take that record and join with the other required tables to pull the updated record. But these logic seems different.how to build the query for the above delta process? Since it is an urgent requirement need to implement asap.
I have a table with the next structure:
DECLARE @MaxCountHistogram TABLE
(
MaxId INT IDENTITY PRIMARY KEY NOT NULL,
PublicationId INT NOT NULL,
ProviderId INT NOT NULL,
DateLog DATETIME NOT NULL,
Amount FLOAT NOT NULL
)
INSERT INTO @MaxCountHistogram
VALUES(432,3,'20150530',10.2564),(432,3,'20150630',13.2564),(432,5,'20150530',8),(432,5,'20150630',13),(433,3,'20150530',9),(433,3,'20150630',11),(433,5,'20150530',13),(433,5,'20150630',21)
I need to take for each Publication and Provider and getting the diferential between two different months, for example:
Period Delta Amount Provider PublicationId
20150530 10.2564 3 432
20150630 3 Result of (13.2564- 10.2564 ) 3 432
Hi all,
In an approach of building an ETL tool, we are into a situation wherein, a table has to be loaded on an incremental basis. The first run all the records apporx 100 lacs has to be loaded. From the next run, only the records that got updated since the last run of the package or newly added are to be pulled from the source Database. One idea we had was to have two OLE DB Source components, in one get those records that got updated or was added newly, since we have upddate cols in the DB getting them is fairly simple, in the next OLEDB source load all the records form the Destination, pass it onto a Merge Join then have a Conditional Split down the piple line, and handle the updates cum insert.
Now the question is, how slow the show is gonna be ? Will there be a case that the Source DB returns records pretty fast and Merge Join fails in anticipation of all the records from the destination ?
What might be the ideal way to go about my scenario.. Please advice...
Thanks in advance.
i would like to know the best practices to choose the columns which should be used for delta?.If, i consider Customer ID as part of delta.

Is there a way to capture every change made in a database? I would like to be able to audit and report on all changes made in our corp. database. Is there a system tool or function that can accomodate such a thing? Transaction Log maybe??

Hi,
We would like to capture events in our system. There seem to be
three obvious capture points for us - application, triggers, transaction
log. The latter seems to be the most attractive, since we`re looking
for a solution with minimal performance impact. In general, our
problem is similar to populating data warehouses from on-line databases.
Can anyone proffer some advice? In particular, being quite new to
SQL Server, I am not sure how difficult/possible it is to read the
transaction log in order to cull events. Some direction here would
be greatly appreciated.
Thanks,
Karl
Hi all,
Is there anyway to capture the SQL Server Error and act accordingly?
I donot want sql server to raise an error when a Primary key violation has occured. Instead i want to capture that error(number,description etc) and act
accordingly.
Whats happening is, from the application we are trapping this sql error
and raising it. Instead, if somebody inserts a record which already exists, then we want to trap that error from the sqlprocedure itself and then do an update to that record.
thanks for the help
Hi All.
I have this project that I need help with. There are 9 tables that I need to capture everything that happens to them (update, insert, delete). I was thinking of creating triggers. If someone does any of these actions against them then I need to insert into another table the date, the table name, the command that was run, and the records that are affected by it. Now I know how to do the date and table name, that's easy. My question is how do I capture the command. Once I have the command I can get the records affected.
If anyone knows how to do this, please help.
Thanks,

I've situation where I've to capture a DML executing against let say Table1 and later may at the end of the day or week I want to be able to extract all the DML executed against Table1 and execute them against similar tables on different sql server to synchronize the data. I don't want to use profiler as this is quite expensive resource for my problem niether can use any third party tool.
Is it possible to capture sql statement in the trigger?
I hope I made my question clear. Urgent help will be highly appreciated.

I have a stored procedure which will do 2 insert statements on 2 different tables. In my 2nd insert statement, I need to know how to capture the exact identity primary key value of the newly inserted record from the first insert statement. I am not sure how to get the correct key value of the new record because there may be more than one user inserting at the same time. Therefore, it is tough to capture the key value that belongs to the user doing his transaction at the time. Please help out. Thanks in advance.blumonde

Using SQL Server 2000
I have to leave a production trace running for a couple of days to track down a little bit of data corruption. I am setting the stop time and maximum file size and I am running it from another machine and writing to a file and not a table and all of that good stuff.
however since I am going to be leaving this running for a while I do not want to deal with a gigantic file to sift through I am trying to limit my trace to all of the stored procs, which can be coming from other databases, to those inserting and and updating a particular table.
I have been goofing around with the Objects:Closed and Objects:Open and the SP:Starting And SP:Completed events, but I can not seem to make this work. I skimmed through the first 5 pages of my google search and my BOL search, but came up empty.
Is this possible? I thought I had done this before.
I need to capture the logout time and login time. I can capture the login time already but I cannot capture the logout time.My logout time and login time need to be on the same entry.This is the coding in the logout button:

I also need to do in global.asax. And this is the coding:
protected void Session_End(object sender, EventArgs e)

{

}
//string emailaddress = (string)Session["emailaddress"];

One of my co-worker told me I can do this to capture errors and insert into error table but when I test it, it doesn't work. Here is what I try to accomplish. SQL 2012. In reality, I have more complicate queries than below.
1. Insert data FROM SourceEmployee INTO Employee table and capture emp_id and error msg insert into dbo.##temperror table
2. Continue on the process until no more record. Basically, skip the error records and do a while loop until end of record.
--DROP TABLE dbo.Employee;

[last_name] [varchar](20) NULL,
