HOWTO: Write Formula Engine Using T-SQL
Mar 29, 2004This came from our actuaries, - create a formula generation and processing engine.
They have a dozen of well-normalized base tables that contain statistical data on competitors, broken down by state, county, city, and zip.
The result should contain aggregated breakdown by the same set of data elements, but also include along with other things an input formula and its result for the Base Rate.
The whole thing is a mini-Monte Carlo simmulation.
THE TRICK:
If the formula today looks like:
x = ((a + b) * (c - d + e)) / (a * (c - d) * (f - d) * (e + d))
then tomorrow it may look like:
x = a * b * c * d * e * f
THE REAL TRICK: It should not be based on dynamic SQL!!!
Any thoughts?...
HowTo: Read/write Package Level Variables In Custom Task
Oct 13, 2006Hello all,
I have been struggling trying to read and/or write package level variables from within my custom task. I'd like to be able to get and set values from within the Execute method of my custom task. I have searched this forum and the books online and can't seem to find the answer. I thought maybe I could use an expression on my task (mapping the package variable to a custom task public property) but that doesn't seem to be working for me. I also would have thought I could use the VariableDispenser object from within my task but the collection is empty. I have 3 package level variables configured and can't seem to find a way to access them (with intentions of getting/setting). Could someone point me to a good doc or provide an example that may accomplish this? Thanks!
(I'm using package level variables as a means of passing simple information between tasks that are not using a DB, if there is a better way I'm open to suggestions.)

Help Me Write A Search Function Please

Now I need to populate the GridView to display the result, based on the input of the textbox... So if only the "SongTitle" have input, it will search for the Song Titles on the database... if the Artist is searched, then it will return the artist...

For the "Artist", I have 2 columns in the Database (originalArtist and performer), so for the Artist select statement, it need to check both columns on the table, if any of them match then it will return the item.

How Do I Write An OUTER APPLY Without A Table Function?
Nov 1, 2006I'd like to select the last unshipped order, or if none is open, the last shipped order, for each customer. I noticed that all the examples on line for OUTER APPLY involve table-valued functions, but I have read (in a book I don't have here) that a subquery can work. The following shows what I want, but it isn't valid syntax:
SELECT c.CustomerName, oa.OrderNumber, oa.Status
FROM Customers c
OUTER APPLY (
SELECT TOP 1 CustomerID, OrderNumber,
CASE WHEN ShipDate IS NULL
THEN 'due ' + CAST(DueDate AS VARCHAR)
ELSE 'shipped ' + CAST(ShipDate AS VARCHAR)
END AS Status,
CASE WHEN ShipDate IS NULL
THEN DueDate + 1000 -- Give open orders priority.
ELSE ShipDate
END AS SortOrder
ORDER BY SortOrder
) AS oa ON oa.CustomerID = c.CustomerID
Need Call A DB Function In The Middle Of The Dataflow Process
Jun 19, 2006
All,
I have to use a field that is calculated in a data flow process and call a database function (return a value) to do anther calculation; then return a value back to the data flow. I tried OLD DB Command but I cannot configure to return a value back to the same data flow.
If there any transformations that can call a DB function and get a value from the function in the middle of the data flow process? Need more detailed instruction.
The data flow is Like:
SourceDB Ã New_filed 1 = field1 + filed2 Ã New_filed 2= DB_function (New_filed 1) Ã Destination DB
Thanks in Advance

How To Write A Function With Integer Parameter Accepting Null
Jan 19, 2007I've got a function which inserts into a database, and has arguments for each item being inserted
A couple of the items are integer datatypes (in SQL), but they will accept nulls
When I add my parameters, it asks to explicitly use the SQL datatype (which is integer):.Add("@myParam", SqlDbType.Int).Value = myParam
In the header of the function, I assumed I could make the argument optional - Optional ByVal myParam as Integer=System.DBNull.Value
However, when the function runs, I always get an error:System.InvalidCastException was unhandled by user code Message="Conversion from type 'DBNull' to type 'Integer' is not valid."
I make them all Optional (which won't happen, but various arguments may be, at different timesand I get this error, with the last item (which is on a separate line), in red:Constant expression is required.
How can I get around this?
How To Write A Function That Will Return True If User Is In A Certain Role?
Jul 20, 2005I have a SQL database with an Access front end. In the database Ihave a read only and a read write role. When a read only user opensthe database I want all the fields on the form to be locked so thatthe user will not try to change data and get an error from the server.Right now I am doing that with a table. But it's a hassle to have tomaintain a table when if I could answer the question is the currentlylogged in user in the read write role?My server is running SQL Server 2000. So I was wondering if I couldwrite a function to do this? The function would take the role beingchecked as a text parameter and return true if the currently logged inuser is in that role or false if he/she isn't.

Output And Error Output Write The Same Table At The Same Time, Stall The Process.
Aug 30, 2006Hi
I have Lookup task to determine if source data should be updated to or insert to the customer table. After Lookup task, the Error Output pipeline will redirect to insert new data to the table and the Output pipeline will update customer table. But these two tasks will be processing at the same time which causes stall on the process. Never end.....
The job is similiart to what Slow Changing Dimention does but it won't update the table at the same time.
What can I do to avoid such situation?
Thanks in advance,

FCB::Open: Operating System Error 32(The Process Cannot Access The File Because It Is Being Used By Another Process.) Occurred W
Dec 3, 2007Hello all,
I am running into an interesting scenario on my desktop. I'm running developer edition on Windows XP Professional (9.00.3042.00 SP2 Developer Edition). OS is autopatched via corporate policy and I saw some patches go in last week. This machine is also a hand-me-down so I don't have a clean install of the databases on the machine but I am local admin.
So, starting last week after a forced remote reboot (also a policy) I noticed a few of the databases didn't start back up. I chalked it up to the hard shutdown and went along my merry way. Friday however I know I shut my machine down nicely and this morning when I booted up, I was in the same state I was last Wenesday. 7 of the 18 databases on my machine came up with
FCB:pen: Operating system error 32(The process cannot access the file because it is being used by another process.) occurred while creating or opening file 'C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataTest.mdf'. Diagnose and correct the operating system error, and retry the operation.
and it also logs
FCB:pen failed: Could not open file C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataTest.mdf for file number 1. OS error: 32(The process cannot access the file because it is being used by another process.).
I've caught references to the auto close feature being a possible culprit, no dice as the databases in question are set to False. Recovery mode varies on the databases from Simple to Full. If I cycle the SQL Server service, whatever transient issue it was having with those files is gone.
As much as I'd love to disable the virus scanner, network security would not be amused. The data and log files appear to have the same permissions as unaffected database files. Nothing's set to read only or archive as I've caught on other forums as possible gremlins. I have sufficient disk space and the databases are set for unrestricted growth.
Any thoughts on what I could look at? If it was everything coming up in RECOVERY_PENDING it's make more sense to me than a hit or miss type of thing I'm experiencing now.
[Execute Process Task] Error:The Process Exit Code Was -1 While The Expected Was 0.
Mar 11, 2008Dear list
Im designing a package that uses Microsofts preplog.exe to prepare web log files to be imported into SQL Server
What Im trying to do is convert this cmd that works into an execute process task
D:SSIS ProcessPrepweblogProcessLoad>preplog ex.log > out.log
the above dos cmd works 100%
However when I use the Execute Process Task I get this error
[Execute Process Task] Error: In Executing "D:SSIS ProcessPrepweblogProcessLoadpreplog.exe" "" at "D:SSIS ProcessPrepweblogProcessLoad", The process exit code was "-1" while the expected was "0".
There are two package varaibles
User::gsPreplogInput = ex.log
User::gsPreplogOutput = out.log
Here are the task properties
RequireFullFileName = True
Executable = D:SSIS ProcessPrepweblogProcessLoadpreplog.exe
Arguments =
WorkingDirectory = D:SSIS ProcessPrepweblogProcessLoad

Execute Process Task Error - The Process Exit Code Was 1 While The Expected Was 0.
Jan 30, 2007How do I use the execute process task? I am trying to unzip the file using the freeware PZUnzip.exe and I tried to place the entire command in a batch file and specified the working directory as the location of the batch file, but the task fails with the error:
SSIS package "IngramWeeklyPOS.dtsx" starting.
Error: 0xC0029151 at Unzip download file, Execute Process Task: In Executing "C:ETLPOSDataIngramWeeklyUnzip.bat" "" at "C:ETLPOSDataIngramWeekly", The process exit code was "1" while the expected was "0".
Task failed: Unzip download file
SSIS package "IngramWeeklyPOS.dtsx" finished: Success.
Then I tried to specify the exe directly in the Executable property and the agruments as the location of the zip file and the directory to unzip the files in, but this time it fails with the following message:
SSIS package "IngramWeeklyPOS.dtsx" starting.
Error: 0xC002F304 at Unzip download file, Execute Process Task: An error occurred with the following error message: "%1 is not a valid Win32 application".
Task failed: Unzip download file
SSIS package "IngramWeeklyPOS.dtsx" finished: Success.
The command in the batch file when run from the command line works perfectly and unzips the file, so there is absolutely no problem with the command, I believe it is just the set up of the variables on the execute process task editor under Process. Any input on resolving this will be much appreciated.
Thanks,
Monisha
Execute Process Task - Error :The Process Exit Code Was 2 While The Expected Was 0.
Mar 20, 2008
I am designing a utility which will keep two similar databases in sync. In other words, copying the new data from db1 to db2 and updating the old data from db1 to db2.
For this I am making use of the 'Tablediff' utility which when provided with server name, database, table info will generate .sql file which can be used to keep the target table in sync with the source table.
I am using the Execute Process Task and the process parameters I am providing are:
WorkingDirectory : C:Program Files (x86)Microsoft SQL Server90COM
Executable : C:SQL_bat_FilesSQL5TC_CTIcustomer.bat
The customer.bat file will have the following code:
tablediff -sourceserver "LV-SQL5" -sourcedatabase "TC_CTI" -sourcetable "CUSTOMER_1" -destinationserver "LV-SQL2" -destinationdatabase "TC_CTI" -destinationtable "CUSTOMER" -f "c:SQL_bat_Filessql5TC_CTIsql_filescustomer1"
the .sql file will be generated at: C:SQL_bat_Filessql5TC_CTIsql_filescustomer1.
The Problem:
The Execute Process Task is working fine, ie., the tables are being compared correctly and the .SQL file is being generated as desired. But the task as such is reporting faliure with the following error :
[Execute Process Task] Error: In Executing "C:SQL_bat_FilesSQL5TC_CTIpackage_occurrence.bat" "" at "C:Program Files (x86)Microsoft SQL Server90COM", The process exit code was "2" while the expected was "0". ]
Some of you may suggest to just set the ForceExecutionResult = Success (infact this is what I am doing now just to get the program working), but, this is not what I desire.
Can anyone help ?
Integration Services :: Dataload Process - Error Capturing Process
Aug 20, 2014I'm pulling data from Oracle db and load into MS-SQL 2008.For my data type checks during the data load process, what are options to ensure that the data being processed wouldn't fail. such that I can verify first in-hand with the target type of data and then if its valid format load it into destination table else mark it with error flag and push into errors table... All this at the row level.One way I can think of is to load into a staging table then get the source & destination table -column data types, compare them and proceed.
should I just try loading the data directly and if it fails try trouble shooting(which could be a difficult task as I wouldn't know what caused error...)
Transaction (Process ID 66) Was Deadlocked On Lock Resources With Another Process.
Feb 14, 2007Hi Folks,
I am having this table locking issue that I need to start paying attention to as its getting more frequent.
The problem is that the data in the tables is live finance data that needs to be changed and viewed almost real time so what I have picked up so far is that using 'table Hints' may not be a good idea.
I have a guy at work telling me that introducing a data access layer is the only way to solve this, I am not convinced but havnt enough knowledge to back my own feeling up. (asp system not .net).
Thanks in advance
