I have a need to read a table and extract records that matches a criteria (dough!, not that simple). Then I put the record in a text message and send them out via email. Works OK, but the problem is when I have multiple records for one entry. Since SQL doesn't have arrays "per say", I need to load the records on a "temporary array" then assembly the message at the end to include the records. Any suggestions how to "emulate" an array on a stored procedure (SQL), not sure what direction to follow. thanks
writing the query for the following, I need to collapse the continuity. If the termdate for an ID is one day less than the effdate of the next id (for the same ID) i need to collapse the records. See below example .....how should i write the query which will give me the desired output. i.e., get min(effdate) and max(termdate) if termdate is one day less than the effdate of next record.
For performance issue, I believe many program should have a house-keeping procedure to clean up transaction history. Is there any best practice to perform this? Or should it be done simply by moving transaction data from the transaction table into a history table? Any better or consideration that I should be concerned of?
I want to create a view to get records from multiple tables. I have a UserID in all the tables. When I pass UserID to view it should get records from multiple tables. I have a table

I have over 500 transaction records in a single DB process handling within SQL transaction (Begin, Commit, RollBack and End). Is there any limitation for the following rollbacktransaction function to handle more records (eg. over 500 records)?

Catch ex As Exception Throw New Exception(ex.Message) End Try End Sub
I have one ssis package moving the data from staging to destination. In stating table we have the duplicate data. But in destination table 4 columns have primary key. How to handle the duplicate records in oldedb source.
I am working on SQL Server in VB 2008. I have a table 'Records' having 8 columns. I have a search page where I can choose 5 different parameters to search as 'Category' , 'Name' , 'Date' etc.
I can successfully search with a single criteria selected either Category Name Or Date. But I want to create a single SQL command that can search my 'Records' table for either two or all the parameters depending on the selections made by the user.
I am writing a stored procedure that needs a access individual entries in a column with multiple entries delimited by a comma(yeah i know, not 1st NF) . Like this:

is there a function that returns a substring given a delimiter character? the only substring returning function that i found are the LEFT and RIGHT that returns fixed length substring.
I am pretty new to this, so I apologize if this is a trivial questions
In almost all scenarios, where there is an error, it also raises 3-4 other errors like these ones below.
I'm 100% sure, the 1st one is the actual error resulting in package failure and the errors 2-5 is the result of error #1. So what ever code I have in the error handler section of the package gets executed 5 times.
How do I handle this? Can do I hard coding for the error numbers?
1. An OLE DB error has occurred. Error code: 0x80040E07.
An OLE DB record is available. Source: "Microsoft OLE DB Provider for Oracle" Hresult: 0x80040E07 Description: "ORA-01858: a non-numeric character was found where a numeric was expected ".
2. The PrimeOutput method on component "OLE DB Source" (1) returned error code 0xC0202009. The component returned a failure code when the pipeline engine called PrimeOutput(). The meaning of the failure code is defined by the component, but the error is fatal and the pipeline stopped executing.
3. Thread "SourceThread0" has exited with error code 0xC0047038.
4. Thread "WorkThread0" received a shutdown signal and is terminating. The user requested a shutdown, or an error in another thread is causing the pipeline to shutdown.
5. Thread "WorkThread0" has exited with error code 0xC0047039.
Hi all, I’m returning two values from a stored procedure, one is a basic string confirming that an email has been sent and the other is the normal value returned from running an INSERT statement. So in my code I’m using the ExecuteNonQuery() method. I’m not sure how to handle both returned values in my code in my data layer. This is what I have: ExecuteNonQuery(cmd); return Convert.ToString(cmd.Parameters["@ReturnedValue"].Value).ToLower(); Obviously I’d need to return the value returned by the ExecuteNonQuery method as well, normally I’d simply convert the value to an int and precede this with the return keyword like so: return (int)ExecuteNonQuery(cmd); Obviously I can’t do this as I need to return two values, the normal value returned by the ExecuteNonQuery() method and my own output parameter value. Any ideas how I can do both? My current method containing the code further above returns a string but clearly this doesn’t help. I’m guessing that maybe I should return an object array so I can return both values? I haven’t encountered this problem before so I’m just guessing. Please help. Thanks
Hi,Currently we get data from more then 200 different sources and all ofour vendors provide data in different file formats. The problem is wehave more then 100 DTS packages now and the maintainance is verydiffucult.Every time our vendor changes the format we have to change in multipleDTS packages.Is anybody know what would be the right way of reducing the no. of DTSpackages.The type of file formats we get are .xls .txt .dat .csv etc. and .txt& .dat files comes with different delimitters. The # of columns alsovaries from file to file. Is it possible to have a DTS package whichcan handle diff file formats and loads data into a staging table andfrom there based of the source of the file we can move data intorespective tables & columns.We are using SQL SERVER 2000Thanks in advance.Subodh
I would like to know how i can handle multiple columns returned by a subquery via IN clause in case of sql server 2005. I can do that in oracle by using the following statement:
DELETE FROM TEST1 WHERE (ID, ID1) NOT IN (SELECT ID,ID1 FROM TEST2);
Hey all,I am having some serious trouble getting the correct syntax for a select statement to work the way I need it, any help I could get on this would be greatly appreciated.I have a table called Units which stores computers and a table called Software which stores software. I have a bit field in Units called OEM, when this is set to true I don't want the select statement to pull this unit down when I am assigning software to other units.Here is my select statement: SELECT Software.SID, Software.SN, Software.Name, Users.First + ' ' + Users.Last AS 'Assigned User', Units.Make + '-' + Units.Model AS 'Assigned Unit' FROM dbo.Software LEFT JOIN dbo.Units ON Software.SN = Units.SN LEFT JOIN dbo.Users ON Units.UID = Users.UID WHERE (Units.OEM = 'FALSE') AND (Software.SN LIKE '%' + @SearchString + '%')Everything works as expected, unless of course the unit has no software assigned to it yet, it won't return it because its not tied to a Units.OEM field. Is there anyway to have it return ALL records that even arn't joined OR are joined but have OEM set to false?Thanks, let me know if I need to clear anything up.-Matthew
I have a peculiar requirement. I need the unmatched data to passed on a bad data table as well as tied to a dimension "Others". Please guide how to suffice these two condition simultaneously
I have an SSIS package that takes in a flat file and pushes the data into a table. However, once in a while the file will have some bad data in it (for example, this particular time I have too many delimiters on one line). I want the package to redirect the row to an error table and keep going with the processing for the rest of the data. To do this, I have hooked up an error output from the flat file source to an OLE DB destination and assigned all the rows to Redirect Row on Error in the Error Output section of the flat file source. Unfortunately, it does not work! The flat file receives an error and stops. Is this because something different has to happen when it is a problem with the whole row? Any help would be appreciated, thanks.
I am facing problems with concurrent access in SQL Server 2000,The scenario is that the DB contains one huge de-normalized table containing 40 million records.
The application frequently queries this table to populate other derived tables,the sql queries take a long time to return results.
So if one query is in execution the other user's query goes into a wait mode.Please suggest how I can better this.
Hi, i have a package that uses a ForEach loop component to import flat files, and uses an OLE DB Destination component to insert the data into some staging tables (using table fast load with a max insert commit of 1000 rows), the biggest individual table import would be circa 5000 rows. At the end of each file import a stored proc is called to transfer the data into production tables, then the next file is imported.
Periodically (when importing more than 5 or 6 files) the process fails with the error message:
The transaction log for database 'blah' is full. To find out why space in the log cannot be reused, see the log_reuse_wait_desc column in sys.databases
This occurs when committing the data to staging. I do not start any transactions during this process, and the staging tables are cleaned out by truncating them, so i'm not sure exactly what is causing the log file to fill up (i'm not a DBA).
I know this is not specifically a SSIS problem, but can anyone give me a suggestion about the best way to handle the log file during an SSIS import? Should i execute a DBCC SHRINKFILE before each flat file is imported? Is there some other approach i should be taking to either insert the data or to move it from staging to production?
I'm trying to convert a column from a varchar(14) to float, some of the rows contain some non-numeric characters. I've tried to write a cursor to step through the records, run cast(col1 as float) on each record, then use if @@error <> 0 to capture an error but it doesn't work. It steps through fine but when the cast command fails it ends the execution of the script with "Error converting data type varchar to float."
How can i capture this error without having the script fail? Is there another way to get this done?
Hi guys,Got a problem now :( please help...now we got a project handling records saved in a table in a sql2000(will upgraded to 2005 soon) server. every month around a millionrecords will be inserted.now user raised a request, that is, once criterios are matched, theproject should do some backend handle, for example, ifSELECT colID, fieldC, fieldD FROM dataTable WHERE fieldA ='fieldA_valueB'returns some recordset, for each @fieldC, @fieldD we shall do someback-end trick, maybeUPDATE dataTable SET fieldE = 'fieldE_valueF' WHERE fieldC = @fieldCAND fieldD = @fieldDlet's say such a rule is named as rule01. Hope I'm expressing theproblem clearly?my questoin is, shall we do this in Database side, using triggers, orby informing our .net project to do it?1. since the records are coming around 1 millison per month, how can wehandling the performance issue?2. now the rules are still somewhat simple, seems at least we could doit by EXEC or SP_EXECUTESQL. but rules may turn quite complex, forexample, audit log, or more complex issues, shall we do it in .netprogram? but how can a trigger in SQL database informing a .netprogram, or webservice, or windows service? by executeing an executableconsole program?3. user may raise more and more rules, how could we provied a flexiblesolution? i mean we're trying to build it less hard-coded. seems in sqldatabase EXEC or SP_EXECUTESQL are still somewhat flexible, while in..net to do something like eval() in javascript or EXEC in sql server isa little bit troublesome. but, put all these bussiness logic in storedprocedure sounds a little bit weired.guys, hope i have made myself clear. any suggestion? Thanks very mcuhyours,athos.
Hi, Ive got a report using a List item that is vertically displaying the columns from a table. The problem I run into, is that some of the fields in this table contain large blocks of text where the users have entered comments and such.
I am using Textboxes to display this data.
So my report will look something like ----- Field label 1 Field value 1 Field label 2 Field value 2 Field label 3
<white space>
<page break>
Field value 3 ---> this is a big block of text Field label 4 Field value 4 etc ------ It appears as though the report attempts to keep the contents of each textbox together even if that means breaking onto an entirely new page to do this. I would prefer for the data to flow more natrually instead where the page breaks in the middle of the data being displayed should it be too large to fit on the page it started on.
----- Field label 1 Field value 1 Field label 2 Field value 2 Field label 3 Field value 3 --- As much as can fit on this page
<page break>
Field value 3 ---> remaining data that broke over the page Field label 4 Field value 4 etc ------
I have a flat file which has a column (length of 24) . Whenever I have that column more the 24 char length, my package failed. I would like to know if there is any way if I can continue my package in this situation and send my bad row to the output table?
I have been trying to solve the locking problem from past couple of days. Please help mee!!
Scenario: -------------- I have a SSIS package in which 2 data flow tasks. 1st data flow task deletes records from a 5 tables and the 2nd data flow task should insert records into 1 of the five tables after the success of 1st data flow task. This scenario runs in Transacation.
The above scenrio in the 2nd data flow task hangs in runtime. It does not complete. with sp_who2 command i could see that there is an intent share lock(LK_M_IS) on the table and the status is SUSPENDED.
I dont know how to come out of this locking. Please help.
Inside of a for each loop (looping through an ADO record set of objects to import) I have a data flow task (along with many other processes).... if the dataflow task suceeds I log success in a table. If it errors I want it to fail the dataflow task (which will fire off my Event Handler for that data flow and log the failure, email etc) BUT I want it to continue the loop - I can't seem to figure out how to get the data flow object not to fail the whole loop. If any other objects inside the foreach, other than the data flow, fail I would like the whole loop to fail. Also if possible (but not a requirement) I would like it to have a threshold where if the data flow fails X variable times it will fail the package.
I am having difficulty how to not fail the loop when the import data fails..... just looking for a simple "on error next" type logic for that specific object in the foreach but not the rest. Thanks in advance for the help/advice.
I am trying to execute a SP like below in OLEDB source in data flow... and this statement include the insert stament ( row by row transaction).. I would like to creat an error hadling logic so that if the trasaction fail to insert the row then ignore that particular row then, move to the next row without stopping the whole process.. how can i do this?
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.
