My Issue is that, I have to create a package which should read from multiple table from a RDBMS Source.
Right now I have different Source adapters for each table. I want to reduce the number of source adapters.
Can I
1) Create a connection manager and set the connection string from a variable. Set the variable from a script task. Put both of these into for loop container (no of tables).
Issues
a) Most of the table has same schema, but few have different, so all tables which has same schema will work.
For different schema anyway I have to create different data source.
Is there a way to get the last read/write time of a table?
I want to have a few tables, but only allow them to exist if they have been used in the last 30 days. I want to set up a "purge" job to clear out any tables that have not been used in 30 days.
We have poor performance spikes on a drive containing our log file but this is only for reads and seems to be at a time when we run a re-index job. If this is a likely correlation as to poor performance in reading the log file, and what reads are done from a log file.
We have many users with a mobile application running SQL Mobile and using merge replication to get data back to the SQL 2008 R2 database. This has worked very well for many years.
We now have a requirement to have this data reported on using Reporting Services. This is where it gets messy.
Due to a limitation of Report Builder(see this blog) we cannot provide access to users for creating their own reports. The report database is remote from the host and there is no VPN.
We hit upon the idea of creating an almost identical publication but the articles as read-only. It was only after this was done that we started having trouble with our existing mobile users.
It seems that a published article is EITHER Bi-directional OR Read-only even if they are in separate publications.
I then thought of using Transactional Publication but this too is blocked on creation with "automatic identity range support is useful only for publications that allow updating subscribers"(Merge and Transactional publication are mutually exclusive)
So in the final analysis is there a way for me to have merge replication AND some other form of SQL replication/data transfer that can have the same data transmitted readonly to a separate full SQL server database?
I want to use time series algorithm to mine data from my case table and nested table. Case table is Date table, while nested table is the fact table. E.g, I want to predict the monthly sales amount for different region (I have region table related to the fact table), how can I achieve this?
Thanks a lot and I hope it is clear for your help and I am looking forward to hearing from you shortly.
I am confused on key column of case table and key time column of nested table by using Time Series algorithm.
In my case, the case table structure is as below:
Territory key text (the ID is actually dimrisk_key, in this case, I use the name column binding to combine the Territory column of case table Dimrisks),
While the nested table structure is as below:
Cal_month key time (in this case, actually the ID is dimdate_key, again, I used name column bining property to bind the Cal_month to the ID)
So my question is, as the key column of case table has been set to be Territory, as a result, does the model training still cover all the cases (rows) based on the ID of the table?
Also, in the nested table, as the key time column has been set to Cal_month rather than Dimdate_key of the nested table, as a result, would the single series based on the cal_month?
Hope it is clear for your advices and help.
And I am looking forward to hearing from you shortly.
I need to import multiple flat files with different formats into different tables of the sql server database and not able to figure out the best way out in ssis to do so...
What are the possible methods in ssis to do so and if possible the process which can be dynamic as file names or columns might change in future.
I need to take a temporary table that has various times stored in a text field (4:30 pm, 11:00 am, 5:30 pm, etc.), convert it to miltary time then cast it as an integer with an update statement kind of like:
Update myTable set MovieTime = REPLACE(CONVERT(CHAR(5),GETDATE(),108), ':', '')
how this can be done while my temp table is in session?
Any easy way for a batch file or automated process to read from one db and table and what ever entry is missing out of another database + table it writes those missing entries to.
This is a simple table in one db that is filled with usernames, I want to see if there are missing usernames in another db and table and write those entries.
db1.usr_table.usr_name = jdoenew If jdoenew is missing in the 2nd db I will need to write entries like: db1.usr_table.usr_name = jdoenew db1.usr_table.password = tmppassword db1.usr_table.active = 1
I'm looking for a way of taking a query which returns a set of date time fields (probable maximum of 20 rows) and looping through each value to see if it exists in a separate table.
E.g.
Query 1
Select ID, Person, ProposedEvent, DayField, TimeField from MyOptions where person = 'me'
Table
Select Person, ExistingEvent, DayField, TimeField from MyTimetable where person ='me'
Loop through Query 1 and if it finds ANY matching Dayfield AND Timefield in Query/Table 2, return the ProposedEvent (just as a message, the loop could stop there), if no match a message saying all is fine can proceed to process form blah blah.
I'm essentially wanting somebody to select a bunch of events in a form, query 1 then finds all the days and times those events happen and check that none of them exist in the MyTimetable table.
Hey , I have sql server 2000, and i am using Microsoft Application block. I have Transaction Like... SqlConnection conn = new SqlConnection(ASLConnectionString); conn.Open(); SqlTransaction Trans = conn.BeginTransaction(IsolationLevel.ReadUncommitted); But If i have another process that try to read the Table if that old transaction running.. it wouldn't Allow me to read the DATA. i tried Isolation level "snapshot" but that works under sql server 2005 only. so i can not use that. And i have some services that will run during day time. So if anybody have solution to read the data from table...from sql server 2000 even if another transaction is running? Please Give any guideline..Help will be appriciated.
I was wondering how to make a table read-only. I want to make a script that creates a table, adds some data to it, then makes the table read-only to prevent someone from accidentally changing the values.
I need a SP to read table A (1000 records) and updates Table B. I think I have to use Cursor, but I'm not very good at writing SP. Any help would be appreciated. Thanks.

Hi, we're trying to read from a table and write back to the same table and are having a lot of trouble with blocking. What could we do to prevent our application from hanging due to blocking of this type?
I need to read a db Table but sorted by index - is there a generic "select * from tableA sorted by index" where it just uses whatever index it finds (main index) or do i have to name the index?
Is it possible to make a table (or set of tables) within a SQL Server database read only (still granting the db_datawriter fixed database role to database users) without dropping and recreating the db_datawriter database role?
I work on an MS Access project ( *.apd - file) that is linked with a SQL-express server 2005 (local installed). On this server are 2 databases x and y. I linked some tables of database x to y and here's the problem: the linked tables are read-only. My authentication for the server is Windows authentication and I'm administrator. I say this because I think the problem is a security problem.
when I try to change data in the linked table in Microsoft SQL Server Management Studio Express, I get now the follow error: --------------------------- No row was updated.
The data in row 12 was not committed Error source: .Net SqlClient Data provider. Error Message: Transaction context in use by another session.
Correct the errors an retry or press ESC to cancel the change(s). --------------------------------- All other programs are close, except MSE
thanks a lot!!!!!
Can somebody help me to make the linked tables are not read-only? What is the problem, what did I wrong?

I am currently adding 250 databases to a SQL Server (MS SQL Server 2008) using SQL Server Management Studio. It took all day yesterday, and I am sure there has to be another way to do it. The filenames are quite complex and it is not easy tracking which ones I have added. Is there a wee loop or something I can use to add all .mdf and .ldf files in a folder to the server?

HI, We are currently trying to import the Data from one DB to Multiple DBs.And these multiple DBs connection strings must be configurable. This I can do it by reading the connection strings from dtsconfig file and execute it for each DB.Is it possible to execute for all the DBs in parallel(Multithreaded).
i am making a n application which in between deletes the multiple tables from the sql database.
for that i have written the following code:
SqlCommand cmd = new SqlCommand();
cmd.CommandText = "delete from " + dbConstt.DBSchema + ".PicassoSelectivityLog where QTID=" + qtid;
cmd.ExecuteNonQuery();
cmd.CommandText = "delete from " + dbConstt.DBSchema + ".PicassoSelectivityLog where QTID=" + qtid;
cmd.ExecuteNonQuery();
in this way, many more tables are to be deleted.
is there any need to create the new SQLCommand object again and agin for each and every query. can iot be done like the given above or can there be some better method?
TimeStart - Which is the time and date that the user logs in
TimeEnd - Which is the time and date that the user logs out
Using SQL, how do you find who has logged in using the same account within the same time period. In other words, Two people are using the same username and are logged in at the same time.
Your help is greatly appreciated. How do you query each one of the following:
1) SELECT FieldValue WHERE DateTime is from 8:30AM - 12:00PM and 6:00PM - 9:30PM on Mondays thru Fridays (i.e. exclude Sat & Sun) for the whole month of January 2008.
2) SELECT FieldValue WHERE DateTime is from 9:30PM - 8:30AM on Mondays thru Fridays, AND ALL-DAY on Saturdays & Sundays for the whole month of January 2008.
