Checking For Existence Of File Fails During Validation
Aug 29, 2007
OK. Here's my situation. I check for the existence of a dummy .txt file using a script. I send an e-mail if it does not exist and exit package. The .txt file only exists if another .xls file is present which I import. However, during the validation phase of the package, the package fails because the .xls file does not exist. Is there a way to bypass the validation step? The only solution I came up with is to have a two-step job. The first runs the file check step and sends the e-mail. The second attemps to run the package and fails. Not a very graceful exit.

Can someone show me some C# code for detecting if a SQL row exists or not? This seems like a very typical action and I cannot for the life of me find a tutorial online that explains this step. In my code I'm either going to INSERT or UPDATE a record. I tried sending a SELECT command through a ExecuteNonQuery, but only got -1 as a response. Apparently ExecuteNonQuery does not work with SELECT. I then saw that T-SQL has an EXISTS keyword, but I cannot see anyway to use that from within C#.So...can anyone share the typical code they use to identify if a row exists or not within a database. I guess I was execting there to be some method available to do this sort of thing.

So I want to check a directory for a particular extention of file. ex: *.txt, *.zip etc. (I'm using T-SQL by the way)
I tried this:
Code:
insert #a EXEC master..xp_fileexist 'G:wklyld_SQLRMAPOLLOADUntar*.txt'
this code works as long as I give it a specific file name, but if I try the *.txt or *.zip it wont work.
I've also been trying to run
Code:
EXEC MASTER.dbo.xp_cmdshell 'dir "G:wklyld_SQLRMAPOLLOADUntar*.*"
and then copy the results to a temp table and then run queries against the table. But I havent had much luck with that either.
Can anyone help? Thanks in advance.

I'm familiar with how to check for the existence of a table before dropping it using the following command:
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[xxx]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[xxx]
How does one check for the existence of a temp table (using # syntax) before dropping it? I've tried various flavors of this command and none work. One flavor is
use tempdb
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[#xxx]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[#xxx]
CREATE TABLE #xxx (
NumID INTEGER IDENTITY(1,1),
Exhibitor_Id INTEGER NOT NULL,
Company_Id INTEGER NOT NULL
)
Thanks.

I have a situation where our stored procedure inserts records from table_1 to table_2 when they don't already exist (uses the EXIST statement) on that table. If table_1 contains multiple records that are the same, it appears after the 1st record has been inserted, it does not recognize it as being there when it checks the existence when attempting to insert record 2.
Here's an example of the script:
insert into table_2 (col1,col2,col3)
select col1,col2,col3
from table_1 t1
where not exists (select '1'
from table_2 t2
where t1.col1 = t2.col1
and t1.col2 = t2.col2
and t1.col3 = t2.col3)
Data from Table_1 -- Assume that table_2 does not contain these records
col1 col2 col3
AA 11 A1
AA 11 A1
BB 22 B2
All 3 records would be inserted to table_2 in this example.

Hi All,
Not played with SQL for a while and am a bit rusty so please excuse me if I sound like a demented idiot! )
It's for a data migration from something wierd to SQL, I just need to be able to advise whether a table is worth migrating or someone should manually enter the data (i.e. if only six random fields are populated in a table then get a secretary to enter it).
I was hoping someone might have already done this and have a query I can edit?!
As far as I can make out the query needs to loop through every table, loop through every row, check each field for an existance of data and output something useful.
I've stared at this for about 3 hours now and tried several different things and none work.....and it's doing my nut! (
Help!!

Hi all,
While cleaning up some code, I ran across the following statement in a stored proc - the purpose of which is to determine if a table exists in the local database: SELECT * FROM dbo.sysobjects where id = object_id(N'[dbo].[XML_PRINTDATE]') and OBJECTPROPERTY(id, N'IsUserTable') = 1of course I removed it from the IF just for testing purposes, but my quandry is this...
Why chose that select (converting table name to object ID) rather than just doing THIS:SELECT * FROM dbo.sysobjects where name = N'XML_PRINTDATE' and OBJECTPROPERTY(id, N'IsUserTable') = 1
I first thought it was to gain access to the "id" column value (and that may yet be the purpose of it), but the second code seems to work just peachy (I assume because the id column is present in the sysobjects table itself).
A follow-on question is this:
When I try to do the same check from another server (i.e.SELECT * FROM APRECEIVE1.DailyProd.dbo.sysobjects where name = N'XML_PRINTDATE' and OBJECTPROPERTY(id, N'IsUserTable') = 1) it of course fails because OBJECTPROPERTY only looks for the id on the local database.
So, do I CARE if it is a user table? (I am reasonably sure it is, of course) and if so, is there a way to check on the remote server for the object type?
Bottom line is I Think I can just simplify things and check for the object name on the remote server, but just don't want to take away any "warm fuzzy feeling" generated by the original stored proc, if such a warm fuzzy is of any benefit (though don't get me started on the relativity of warm fuzzies, I wrote my Thesis on that ;) )

I have a parent package that calls a child package, when I run the parent package the child package picks up a variable value from the parent in a script task and runs fine, the problem I'm facing is when I run just the child package, the script task fails because it doesn't know about the parent variable. The dilemma I'm facing is in my child script task, if I add the parent variable to the ReadOnlyVariables list then the task fails because the parent variable doesn't exist when I just run the child. If I don't add the parent variable to the ReadOnlyVariabls list then if I try to use it then the task fails saying that the variable doesn't exist in the variables collection.
Is there a way to check for the existence of the parent variable, so when I just run the child package I don't get an error and I don't have to change my task every time I choose to run the child package only vs running the parent/child?
Thanks.

I want to do something with error checking in my company. For this we have a selection of different tables and the data needs to meet various validation rules else it is classed as an error.
To deal with this I'm currently thinking of this approach:
1. Create a view pulling all of the various data together from the multiple tables.
2. Create an empty 'errors' data table.
3. Create an Excel file with a button to call a Check for Errors Script
Then in the the script:
1. Clear the 'errors' data table
2. Call multiple scripts, each of which uses the new view, applies the checks for that specific error and writes any erroring data into the 'errors' data table (along with a text string with the unique error code for filtering / sorting purposes).
3. After calling all the scripts, the table can be refreshed in excel when when used with a pivot table can show the various errors, and let us drill down into all the data so we can fix them.
Also.. Ideally, I'd like some way to write comments in an excel column for each entry and error code and be able to write that back into a comment table.

Problem:
When migrating packages to production using the DTSInstall program, phantom validation warnings are occurring.
Background /Installation options
We use the DTSInstall program to migrate code to our DEV, QA, and Production servers. Our migration process includes saving the package to the SQL server (msdb) and validating the package after install. In our most recent production migration, the package being migrated encountered warnings when validating after the install ("The package path referenced an object that cannot be found...") This warning seems to mean that I have configuration that cannot find an object to configure in the package. This error did not occur in other environments with the same code and configuration.
Troubleshooting performed:
1. Validate that configuration in all environments matched (ie. PackagePath was identical in all environments).
2. Opened the package on production server in Visual Studio, and received same warning message.
3. Executed the package in production using the validate only option: no validation warnings found.
4. Executed the package in production; package ran successfully and as expected.
5. Migrated the package from QA using dtutil and executed the package in production using the validate only option; no validation warnings found.
At this point I think I may have a problem with the DTSInstall program or the Visual Studio environment on our production box? Does DTSInstall use any parts of Visual Studio when running? Anything I am missing?

Now is this a limitation in SSIS or am I missing something. I have an XML file that needs validation. I am using the 'XML Task' control for that. The validation runs fine so long as the file is below a certain size. I am not sure what the cutoff size is but the validation runs fine if the XML file size is 60Mb. I include a few more records in my XML file to make the file size 65Mb and run ETL again and validation fails!
There is not much detail in the error message other than 'Task XML Validation failed'. I dont think there should be any kind of timeout issue. The whole process takes less than a minute before failing.
The issue is definately not with the new records that get added. I have verified the new file with xmlspy and it validates just fine. I have also validated the newly added records (5 Mb) through the same ETL process and that runs fine too.
Please suggest if I should spend time finding what the issue is or simply move on assuming its a known bug? Has any one experienced this?
Thanks,
Sumeet

Hi,
Does TSQL provide methods to check if a file exists?
For example, a TSQL script will read data in a .dbf file into SQL Server. It will check if the file exists before read. How to do this check?
Thank you.

I have a data flow task inside a foreach loop container which will take multiple excel files and load into a sql table. Once all the excel files are loaded into the table, then at the end one of the column gets updated using execute sql task. Now I am trying to check for a file existence, if the file is not present in the folder then the data flow task should not be executed. Any help is greatly appreciated, I am thinking of using file system task for this, but not exactly sure. Thanks in advance.

Two questions actually ...
1) Need a simple routine or system function for testing for or verifying the existence of a file or folder on the local server's file system. Returning a simple boolean value or 1 or 0 would be fine.
2) Need a syntax and use description of the new "master.dbo.xp_create_subdir" function ... anyone have some documentation or links? MS technet and MSDN have nothing.
Thanx

Hi,
I am quite new to SSIS (I was a DTS developer) and I have a specific requirement to validate all incoming data using regular expressions. For each row in my input file, all columns will need to be validated against an expression. We have approx 60 different input files (a combination of xml and text files) with column counts going from 10 up to 120.
Also each input file will contain a footer which will need to be validated for record counts.
I would like the solution to be as generic as possible as the requirements for each file are similar -the only difference being the column names and the expressions to check against. I would really rather not have a different data flow task for each input file type as there are so many.
Can anybody suggest the most efficient/reusable way to do this? What I was thinking of was this:
Split the input file into detail/footer
create a temporary table based on the input file type with CHECKconstraints (regular expressions) for each column
for each detail record load it into the temp table
redirect any failures to another destination e.g. sql error table
Any other ideas would be very helpfull
Many Thanks
Gaye

Hi,
I have migrated a DTS pakage into SSIS. The DTS package validates a Textfile Source File using an ActiveX Script task.
Could somebody tell me how to validate a FlatFile in SSIS. Based on whether the file exist or if exist then whether its empty or not, I have to execute a database proc.
It'll be very helpful if somebody can assist me in this.
Thanks in advance.

There is an execute package task that calls the child package. Both parent and child packages have the same password and the passwork is entered into the execute package task. Both packages reside in the same directory path.
Error: Error 0xC0012050 while loading package file "C:Documents and SettingsuserMy DocumentsVisual Studio 2005ProjectsExecutePackageTestExecutePackageTestExtractandWrite.dtsx". Package failed validation from the ExecutePackage task. The package cannot run.
When ExtractandWrite.dtsx is executed by right-clicking on package, the package executes without any errors.
DelayValidation = True for the Execute Package Task tasks is set and DelayValidation for the connection manager is set to True.
Does anyone have any thoughts as to what might be causing this error?
Thanks in advance for your assistance.

Greetings all.
How can I check for file exitence in a specified folder using TSQL?
I can think of a couple of ways to do this so any feedback would be appreciated.
Load the contents of a folder in to a temporay table and check the table for file name. I can do this with something like:
insert into myFiles
exec master..xp_cmdshell 'dir /B /OND filePath*.txt'
Or maybe use OLE Automation Sproc? But I am not sure which method I should use.
Please advise.

We have the following scenario: We receive CSV files every month for which SSIS packages were built to process the data. The following problems occur from time to time:
1. The structure of the CSV file changed (e.g. column added or removed)
2. There were no footers in the data, but now footers started to appear
3. Date format changed (e.g. used to be mm/dd/yyyy, but became mm.dd.yyyy)
4. Number format changed (e.g. from 2000 to 2,000)
Currently we have person who manually opens each file, and using our "validation document" validates to ensure none of these or similar problems occur. We would like to move away from this manual process if possible. I understand that items 3. and 4. could be caught by loading data into a staging table with VARCHAR data types, and performing validation before moving it any further.
Item 2 is a bit questionable (meaning depending on the footer size SSIS load could fail or not).
Item 1, however, is a sure fail of the SSIS package that directly loads the data into a table.
Thus I feel the two possible options are:
1. Create a custom script that will run through the file, row by row, apply all the necessary validations and report an error or continue if all checks out
2. Use some 3rd party tool to validate the files (semi-manually) before kicking off the SSIS processing.

I have a package set up basically with two consecutive data flows. The first flow takes data from an OLE DB Source and stores it into a Flat File Destination. The second flow uses this same flat file as a source, alters the data, and stores the data in the same flat file, overwriting the old file. I set DelayValidation to True on the flat file. Still, here are the error messages I am receiving:
Error: 0xC020200E at DO, Flat File Destination [7676]: Cannot open the datafile "C:Temp.txt".
Error: 0xC004701A at DO, DTS.Pipeline: component "Flat File Destination" (7676) failed the pre-execute phase and returned error code 0xC020200E.
I am new to SSIS, so I'm sure I have a setting wrong or something. Is the problem that SSIS is trying to write to a file from which it is simultaneously reading data?
Thank you.
