Hello guys,
Using SSIS, I want to check if a specific file exists on an FTP server or not. If yes, then i'll go with a flow, and if not, i'll go with another flow. Any help with that?
Thanks in advance

I'm trying to write a program in cold fusion to check the existance offields and data types according to requirementsI was looking at the syscolumns table for some of this information butI've discovered that in my playing (creating and deleting tables) threare multiple entries for a field that is in table that is created thendeleted then created again.Is this a problem? Is there a better way to get at the information iethe table, field, and type exist in a database?
View 2 Replies View RelatedHow do you determine in a (SQL table or view) calcualted field (yes/no) if a file exists.
Specifically, I have a view with a field (column) that calculates a filename (path plus file name from another field, plus extension. I want to determine if that calculated file name represents an existing file.
Also, if you could consider replying to this as well: How to determine file existance in ASP, when the file is not on the same server as the internet service (which is easy), but resides on another server, or when a URL is given for the file location.

Hi all,
Let me apologize in advance for what I know is a very basic question,
but so far I'm not being terribly successful trying to find sample code
to learn from.
I'm trying to write (my first!) .Net Script in SSIS to check for the
existance of a file (since that seems to be the only way to do it).
I've created the Script Task, with the following settings:
PrecomplieScriptIntoBinaryCode = False (it complained at one point in time (possibly on validation))
EntryPoint = ScriptMain
ReadOnly Variables = ProductBuyListFileLocation, ProductBuyListFileName
ReadWrite Variable = FileFound
Now the ReadOnly variables have the 2 components necessary for a file location, i.e.:
ProductBuyListFileLocation = 'D:TestingProductInformationEnhancements'
ProductBuyListFileName = 'buyList.xls'
So, I'm now trying to check the existance with the following .Net Script code:
-------code--------
Imports System
Imports System.Data
Imports System.Math
Imports System.IO
Imports Microsoft.SqlServer.Dts.Runtime
Public Class ScriptMain
' The execution engine calls this method when the task executes.
' To access the object model, use the Dts object. Connections, variables, events,
' and logging features are available as static members of the Dts class.
' Before returning from this method, set the value of Dts.TaskResult to indicate success or failure.
'
' To open Code and Text Editor Help, press F1.
' To open Object Browser, press Ctrl+Alt+J.
Public Sub Main()
'
' Add your code here
'
Dim FileLocation As String
Dim DTSVariables As Variables
If
System.IO.File.Exists((CStr(DTSVariables("ProductBuyListFileLocation").Value)
+ (CStr(DTSVariables("ProductBuyListFileLocation").Value)))) Then
DTSVariables("FileFound").Value = 1
Else
DTSVariables("FileFound").Value = 0
End If
Dts.TaskResult = Dts.Results.Success
End Sub
End Class
-------code--------
if fails with this message, which I'm not finding too helpful:

Is it complaining about not being able to find/address my ReadOnly variable? If so, what am I doing wrong?

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.

I need to be able to see if the incoming csv file had a head row different than the previous files header row. That will tell me that I have new columns.
View 3 Replies View RelatedOK. 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.

Hi!How may I find out if a specific SQL Server database exist or not, through a VB.NET application?
Much obliged to you for your attention. Regards!
Hello,
In a DTS, I want to check whether a certain table already exists. If so, it should be deleted.
Any ideas how I can do that? ActiveX (if so, how)?
hi all,
how do i check if a temp table of a given name already exists on the current connection?
in the application i am working on, some reports are very complicated and use temp tables generated on the fly. these tables do not get cleared up sometimes and the next table generation statement bombs. i do not want to touch that code.
thanx.

Hi,
I need to test for the existance of a stored proc on a specific database(s) on a server(s), and get the user assigned permissions/roles.
Is there a built in system proc that returns such information?
Thanks,
Within the execution of a t-sql script how do I check for the existance of a temporary table associated with the session or a global temporary table?
My understanding is that the table name doesn't get placed in the current database sysobjects table - it goes into tempdb. But the object name is cryptic (so as to be unique) and I see no way of associating it with the current session (@@SPID).
Thanks,
Fred
Hi there,
I was wondering if there's a way to check if a temp table already exists on my db.
I used to do that for regular table:
IF EXISTS(SELECT name FROM sysobjects WHERE type='U' AND name = 'myTableName')
... do something ....
But it doesn't works with temp table... Is there a way to do it ?
Thanks

Hello all,
I am trying to add columns to several tables in a singular database. I want to check to see if the column exists in a given table first before executing the alter table command so that I can skip that command if the column already exists, and avoid aborting my script prematurely. I can't seem to find a way to check for the column's existance. Any suggestions?

Hello,
I connect from SQL Server on Windows 2000 to Progress
Database on UNIX.
The database name of SQL Server is cstarsql and the
name is cstarint on UNIX.
I would like to schedule to copy data from
cstarint(Progress) to cstarsql(SQLServer). I did for
one time, but I want to control if the data has
already copied or not. If not, it will copy.
In DTS Query Builder to copy from Progress to SQL
Server,
SELECT * from calls WHERE call_date = TODAY
The name of table of calls is the same for both
database.The above calls is cstarint(Progress
Database)
This command is enough for one time. But I need to
control if the record has already copied.
In SQL Server, I control if the record is available or
not with @@FETCH_STATUS .
Now I would like to mix two queries, but I couldn't.
Can anybody do this?
DECLARE calls_cursor SCROLL CURSOR
FOR SELECT * FROM calls
WHERE call_date = TODAY
OPEN calls_cursor
-- Perform the first fetch.
FETCH NEXT FROM calls_cursor
-- Check @@FETCH_STATUS to see if there are any more
rows to fetch.
WHILE @@FETCH_STATUS = 0
BEGIN
-- This is executed as long as the previous fetch
succeeds.
FETCH NEXT FROM calls_cursor
END
CLOSE calls_cursor
DEALLOCATE calls_cursor

View 2 Replies View RelatedI have a list of servers on a table, I take this list and pass to a for each loop container and that will grab some system information from each server that we give for our internal auditors.
The issue that I'm currently having with this package is that some times, 1 or 2 servers from the list are down and/or extremelly busy and it times out, either case causes the whole package to fail.
What I'm trying to do is, test the connection to the server prior passing the server name to the For Each Loop Container and log that information somewhere (Maybe a boolean field in a table), so then I check after the package finish and validate that the server was actually up or down.
Any ideas or suggestions?
Thanks,

Is there a quick way to determine linked server availability. I've got some select statements wrapped up in TRY/Catch blocks which will re-direct any failures to retreive data from a linked server to the catch block and I can get my data from elsewhere, but I have to wait for the statement to fail before I can jump into the catch block. I hoped to speed the process up by using an if exists check on the status of the linked server . Is there such a thing as a quick check on whether or not a linked server is online?

I am building an SSIS package that is hitting about 50 remote servers. I have a for each loop container that i am using to build the list of servers to run.
The problem is...sometimes networks go down, sometimes connections time out and this causes my entire package to fail. I inserted a task that will run select @@ServerName on the remote server inside the loop. My thought was, if this returns an error I could ignore it and move on to the next server in the list and log somewhere that server x threw an error. Logging is easy, the problem is, how do I then tell it to move on to the next server in the loop?
If anyone has any suggestions on how better to do this, I am open for alternatives...
Here is my situation. I have a table in my application that pairs users with cars they like. We'll call this table Favorites. A user can browse the site and they can designate as many cars they want as favorites. For example, a user can go to the Honda Accord page and add that as a favorite car and then go to the Toyota Camry page and add that as a favorite car. However, if he/she goes to that Honda Accord page and tries to click the "Add to Favorites" button again, at the present state of my application, it will just add another entry into the Favorites table with a duplicate pairing. So, if I were to datalist the table to generate a listing of all favorites belonging to a certain user, he/she may potentially be returned with superfluous duplicate entries. Not to mention, taking up valuable database space and not looking very professional.
In my Favorites table, the 3 fields are.....favoriteId (set as primary key)userIdcarId
I've been thinking about this for awhile and I've come up with 2 solutions. I'm a newbie to ASP.NET/programming so I don't have enough insight to make a decision or to even think up of other alternatives.
1) Check proactively by doing a.....SELECT favoriteID FROM Favorites WHERE userId = x and carId = y (where x and y are variables)If I get a null return, it means I can go ahead and let the user add the car as a favorite in the database. If I get a valid value, then it means there already exists the same pairing, so I exit out without updating the table.
2) Check reactively by forcing an exception whenever a user tries to enter a duplicate pairing. I'm not sure how to do this, but perhaps, instead of making "favoriteId" a primary key, perhaps, I can make a primary key pairing of "userId" and "carId". And by trying to do an insert with a primary key that already exists, we know it won't work since primary keys by definition are unique.
Now, I expect some concurrent users on my site, so I must take into consideration pros and cons of each and determine which is more efficient. Checking proactively will force a check even if the table does not contain a duplicate pairing of user and car. However, having a duplicate primary key may be more expensive from a database point of view and may slow down lookups, etc. Or maybe neither has significant benefits, in which case, I rather go with proactive, since I've already coded it and it works fine. Or maybe there is a third alternative, which I did not think. Which method do programmers usually take and which is a better practice?
TIA for your help.
Is it possible to get the latest inserted Identity value on a remote server?

Hi All,
I'm a relative novice on SQL Server and am a complete beginner at SQL, so am looking for a little help.
I currently use a DTS package to perform inserts / updates to a "production" table.
The DTS package transforms a comma separated file into a "temporary" table that is truncated / cleared before the load starts.
The temporary table has a column denoting Insert or Update. The production table is almost identical, however, doesn't contain the Insert / Update column. The DTS package then, depending upon the Insert / Update flag, either inserts data into the production table or updates data in the production table.
When the DTS package has completed, I'd like to be able to run an SQL Query that validates everything in the "temporary" table is identical to that in the "production" table, which it should be.
I have managed to do some queries to verify that everything has loaded / updated i.e. select primary_key from temporary table where primary_key not in (select * from production table), however, what I haven't been able to do is verify that all the columns on the temporary table match the values in the production table (excluding the Insert / Update flag).
I tried concatenating the columns in each table and comparing the concatenated values, however, this failed due to the different data-types, i.e. decimal, text etc.
Any help will be greatly appreciated.
Many thanks.
Cheers,
David

I have an VB.NET application connected to a SQL Server Express. I want to let the application to run in either "Normal mode" or "Holiday mode" according to current weekday is normal day or state public holiday.
My approach is to find out all the public holidays in a year and enter them into a Holiday Table. Then some code in my application constantly check the current weekday against the one in the holiday table, if matches, the application goes into holiday mode.
This approach is not perfect as "State public holidays" are confirmed by the state government in the current year and the coming year. So state public holidays are unconfirmed for the third year afterward. The system is required by client to support public holiday in the next 10 years.
I wonder what is the best approach to this problem?

I have a table with EmployeeID, StartDate, and EndDate with a PK of EmployeeID, StartDate. How can I check to see that there's no overlap for StartDate and EndDate for a given employee? That is, on any given day there must only be 1 row for an employee where Getdate() is Between StartDate and EndDate. For an active employee their EndDate is set to 06/06/2079.
I've tried it using Row_Number() with Over() but am returning too many rows indicating overlap when none exists.
