SQL Server 2012 :: SSIS - Stop DataFlow Task If Result Set Is Empty?
Oct 7, 2014
I am trying to create a SSIS package that will create a csv of a dataset for daily events in the database. However there will be days that there was no activity and thus an empty dataset. The package still runs fine but I want to stop the package if the dataset is empty.
FLOW:
DATA FLOW task: get daily data and put in CSV file
FTP TASK: upload the file to FTP server
MAIL/Copy file task: Move the file and then send a confirmation mail on task completion status.
Pretty simple and it all works great, I do have a few complexities in there. What I would like to add and I am at a loss is at the beginning, if the OLE DB Task resultset is empty then move to Mail Task otherwise process normally. I have tried conditional split, derived columns, the only thing I haven't tried in Script task and am not sure about that yet.
I have a 'Execute SQL Task' in my 'control flow', my 'Execute SQL Task' will return a value which I am assigning to a variable. Based on the value of the variable, I need to control my other flows. If the variable's value is 1 then I should invoke a dataflow, else I should write a failure error message in event viewer. Please could someone provide some inputs on how this can be done.
'Execute SQL Task' ----->value 1 ------>data flow to be executed
'Execute SQL Task' ----->value !=1 ------> write some error message in the event viewer and no tasks should be executed after that.
I need to create a ssis package. I want to import the data from a flat file to a table.
Lets say, the table has 5 columns -- col1, col2, col3, col4 , col5.(Assume that all columns can be NULLABLE) The datafile contains the data related to only three columns say col1, col2, col3. So when I use dataflow task to import the data from the file to the table, I will only get three columns, col1, col2, col3. Columns col4, col5 will be NULL. However, I want to populate columns col4, col5 with some values which are stored in the variable.
I have a problem whit loading XML-files into SQL server.
I iterate over the XML-files with the "for each file" component and use the XML source within a Data flow task. This works great until the file count got bigger. After say 1000 files the XML source returns error 0x8007000E. I think this means out of memory. Does anyone have an idea how to solv this. The load must be able to handle up to 5000 files in one batch.
I am using a Data Flow task which copies data from an Excel Source to a SQL Database Table Destination. From 15 columns I require only 10 columns to be imported to the DB Table. So I have mapped those colums. In SQL DB there is a colum called say X, whose value should be the "Remedy" for all the columns which are imported. Is there any task that can achieve it.
Hi, I am using SQL Server2005 for SSIS. I want to change the source connection dynamicaly evertime. Let me clear, I have to extract some column from excel to MS-Access. I am using Data Flow Task and able to successfully complete the job. But problem is that, whenever a new file comes , i must have to reconfigure my Excel Source. All the time column in file are same, so no need to worry about mapping but how can my package select a file automatically. I have a directory, suppose "C:dpak". I should able to pick the filename and sheet name from this directory every time when my package will execute.
I am using SQL Server 2005 Integration Services to create new values for my tables. One step I must do is execute a query and the script task that receive its constraint (it is set to completion) must do different things depending on the query result.
My question is: how can I know the result of the precedence constraint?
I have an sproc that gives an xml result set. I want to save this to a file but by using ssis and script task. Now, I do exec usp_myProc in execute sql task and get the result as xml. (I can get it as result set too but niether has worked). Now I pass this variable to my script task User::XRset.
In the script task I create a file and then I want to write xml result of User::XRset to my file. I am at loss.
I cannot find the data type for parameter mapping from Execute SQL Task Editor to make this works.
1. Execute SQL Task 1 - select max(columnA) from tableA. ColumnA is varbinary(8); set result to variable which data type is Object.
2. Execute SQL Task 2 - update tableB set columnB = ? What data type should I use to map the parameter? I tried different data types, none working except GUI but it returned wrong result.
Does SSIS variable support varbinary data type? I know there's a bug issue with bigint data type and there's a work-around. Is it same situation with varbinary?
I 've got the below RESULT SET after several JOINs & deriving columns from different sources
STUD_ID, ANNUAL_YEAR, COURSES_ID, SUBJECTS_OPTED, CHAPTERS, YEAR_JOINED, Course_Tenure, Sub_ID, SUB_MARKS, EXAM_ID, ATTEMPT_YEAR, ATTEMPT_NO and many more.
Now, I've only one result set available in my DATA FLOW. And I want the below few,
1) STUD_RESULTS:TABLE : Evaluate COURSE-Annual year completion: Have columns Students, Annual_yr, Results (IF ANY SUB _MARKS are below 35? 'PASS': 'Fail') and few more. <--I've got to group the result set on STUD_ID and ANNUAL_YEAR.
2) STUD_COURSE_PERF: TABLE: for course performance. I've got to group the result set on STUD_ID,ANNUAL_YEAR, Course_ID and the other essential
3) STUD_SUB_PREF: TABLE: Evaluating Subjects difficulty I've got to group the result on STUD_ID,ANNUAL_YEAR, Course_ID, SUBJECTS_OPTED and other essentail.
How to use the only result set to carry on different evaluations?I Applied Multicast on the only result set.
I set up a connection to mysql using ADO.NET's ODBC Data Provider. And I'm running a simple query to return one table's maximum ID(int32 unsigned). There is no problem to achieve that.
But when I bind the result to a variable and excute task. It gives out error message: "An error occurred while assigning a value to variable "MaxAuditLogID": "Result binding by name "MaxID" is not supported for this connection type. "
I tried to change the type of variable around but with no luck.
2: Dataflow Task: Datareader--Script componant--OLE DB Destination (SQL Server 2005--a single table --always around 600,000 rows)
How do I set up a transaction where if there is a failure the Truncate Table command will roll back---and the OLE Destination (A single SQL Server table) will be left the same as before the load started.
Another question with that volume of data --600,000 rows will a truncate table be pratical in a transaction
I had the SP, I want to call in Script Task , had the Result set data value then I need pop up message box. So how can I call stored procedure result in message box in ssis script task using C#.
and I want to use SSIS -OLEDB connection.
ConnectionManager cm; System.Data.SqlClient.SqlConnection sqlConn; System.Data.SqlClient.SqlCommand sqlComm; cm = Dts.Connections["OLE_TEST_"]; sqlConn = (System.Data.SqlClient.SqlConnection)cm.AcquireConnection(Dts.Transaction); sqlComm = new System.Data.SqlClient.SqlCommand("Exec dbo.sOp_xx_XXXe_VXX 280", sqlConn); sqlComm.ExecuteNonQuery();
I'm working on a script to produce XML. There are two parts to the XML: an envelope (called "message") and a payload ("payload). Here's an example of what the result should look like:
(Note that I had to add a space between the '&' and 'lt' and 'gt' to get it to post in the forum without the forum converting them back to < and >!)You can see that SQL escaped the < and >. Also the CDATA escape sequence is missing.I want to see < instead of & lt and > instead of & gt. Also, I need the CDATA escape sequence.
This store procedure will get some executable queries from the select statement, the cursor will fetch each rows to execute the query and insert the queries into table_3 to mark as 'E'. Until 17:00, this store procedure will stop execute the queries and just get the queries from select statement insert into table_3 to mark as 'C'.
I don't know why the outputs in table_3 are quiet different than I think. This store procedure comes out with two exactly same queries and one marked as C and another marked as E.
CREATE PROCEDURE procedure1 AS DECLARE cursor_1 CURSOR FOR SELECT 'This is a executable query' FROM table_1 DECLARE @table_2
I have an Execute SQL Task that executes "select count(*) as Row_Count from xyztable" from an Oracle Server. I'm trying to assign the result to a variable. However when I try to execute I get an error: [Execute SQL Task] Error: An error occurred while assigning a value to variable "RowCount": "Unsupported data type on result set binding Row_Count.".
Which data type should I use for the variable, RowCount? I've tried Int16, Int32, Int64.
I'm querying my database with a datetime constraint, only picking up records newer than the last ETL. Although I doubt it would ever happen I was going to put a check in the data flow to trap the case when NO rows were read due to inactivity in the OLAP. I set up a row count and tried to trap it. Apparently if you use an OLE DB source to get a result set and that result set is empty, the program flow bypasses everything and keeps running until it hits something causing an error, like an SQL Insert or Update command.
Is there any way to trap this condition? Currently it is going to cause the program to fail which will cause a snapshot restore (after kicking everyone out of the database).
I have a sql query that gets the count of exams held in each month.
Below is the code that I have used.
select Examid, count(*) as CumCount from [dbo].[Exams] where ExamCategory in ('Major','Critical') and Month(EXOCCRDATE) = Month(getdate()) and Year(EXOCCRDATE) = Year(getdate()) group by Examid
The code works good when we have data for the current month. When we dont have any exams for the current month, the code outputs empty values. I want the code to be altered so that when there is no value returned in the output, i want a default value shown in the output.
I have attached the sample data that I am using. In the data we dont have dates for the month of October. So when I run the code it will display empty output. So what I need is I need a text like 'No Data' to be shown when no value is returned by the query.
We are running SQL Server 2012 SP1 64-Bit EE on Windows Server 2008 R2 SP1. I have a SSIS Package which connects to a FTP Site and downloads a file. Then it truncates a table and loads the file data into a table. This package works okay when executed from within VSS and SSMS (In SSISDB, right click on the package and execute). However, when I execute it as a Job it does not run and appears to be failing on the first task which is the FTP Task. SQL job step - Type: SSIS Package; Run as: SQL Server Agent Service Account (domain account called playuser); Authentication: Windows Authentication.In the All Executions Standard Report for the SSISDB Catalog, it only says: FTP Download File: Errors: There were errors during task validation.
Is this because my domain account does not have access to the FTP Site?Is this where I need to come up with a Proxy Account with Credentials?Do I need to set up a SQL Server Login (Proxy Account) with the same username being used in the FTP Batch file?
FTP Commands in a batch file: username password cd omb asc get STRMASTER quit
Enviroment O.S. = Windows Small Business 2003 DB = SQL 2000 Server with SP3a No windows or third party firewalls that are set up.
Problem: When performing a Link Table in MS Access 2003 it runs into this error message "The Microsoft Jet Database engine could not find the object 'zstblSetup' (the name of our table). Make sure the object exists and that you spell its name and path name correctly.
But when we try to another server but at this time the SQL 2000 is patch with SP4, the link table works fine in Ms Access 2003. So we decided to use SQL Profiler to trace the cause of the problem. It so happen when sp_columns N'zstblSetup' is called no result is returned. Going through the code in sp_columns, it calls spt_datatype_info. When calling spt_datatype_info, again no record is returned. We suspect that spt_datatype_info is the culprit of the problem that's why Link Table in MS Access 2003 doesn't work.
Calling the sp_columns and spt_datatype_info into the working server that I mentioned aboved can return results. The way I understand it spt_datatype_info holds the SQL data type info.
My question is if we apply SP4 in the server that is problematic will this problem be resolved? Or are there any possible reason to solve this problem?
Here is my scenario in my ETL process, I have one DataFlow task. Assuming that i have 10 clean records in my source database and i need to load all the 10 recs into my target table. IS there any means of cross checking the no of rows from source table and number of rows loaded into my target table.
We have a LKP table that we will use to decode incoming codes from multiple sales feeds to link to the relevant surrogate key for the ultimate dimension table.
The LKP table has a start date, end date and active row flag to track history of the codes.
This table in its entirety is required for the FULL history load but we will need a CURRENT version of the table containing only the ACTIVE rows for the DAILY incremental loading.
I am thinking of putting a standard view over the top of the LKP table to present only the ACTIVE rows rather than creating a 2nd table and reloading it each night. We don't have enterprise edition to use materialised views.
My question is, will the LKP cache populate as the SSIS packages begins, loading it with all the rows from the view, as it would if I used the 2nd physical table with only ACTIVE rows?
MS SQL server 2000 behavies strange with big queries that involves relatively large number of tables: If I just enumerate columns I want to receive, the result set is empty. Adding * to the column list without making any change to where clause seems to solve the problem but I guess it's not the best practice. The most amazing is that this behavior is not stable, so I suppose there's something to deal with server itself, not the application. Has anybody suffered this problem and what solution was adopted? Thanks for any information you can provide.
I am getting the following error when I start debugging my Package, I am not sure what this is related to, but basically, input (datatype is a int, and its mapped to a column which is also int), so I am not sure whats happening here. The input column is actually a derived column, and its set as a 4 byte un-signed int, please advice on where should I start looking to troubleshoot this issue. This loanapplicationid is actually a user variable that is utilized by other tasks in my control flow as well:
Error: 0xC020901C at InsertApplicationCL5, OLE DB Destination [16]: There was an error with input column "LoanApplicationID" (1161) on input "OLE DB Destination Input" (29). The column status returned was: "The value violated the integrity constraints for the column.".
I got a text file with two columns. and I need to generate a integer key automatically with the row number (or any distinct number, I thought row number will be OK). and when I make the data flow task to import this text file into a raw file I need to get the unique rownumber as Id. How can I make this in the data flow tak??
I written a SSIS package to import a table from one database to another database. I used dataflow task with oledb source and oledb destination with fastload. For 2 million records its taking 5 min . The same import using DTS I am getting in 2 mins. DTS package is more faster than SSIS package ?. any reasons why SSIS is taking more time?
I want to be able to loop through a view and execute a dataflow task for each record. I would like to pass the value of a column to the dataflow task to be used as a parameter in a data reader.
I am getting data from an external source. External data has a column called "Type". I have a variable in my package which contains the list of types as shown below:
Filtered_type_List = 2,4,8,10,11
If this variable(Filtered_type_List) is blank, then I need all the data from the external source and if it is not blank then I only need the records matching to his list. How can I implement this in DataFlow Task?
In the control flow I have an "Execute SQL Task" that executes a stored procedure. The stored procedure returns a result set of about 2000 rows of data into a package variable that has been typed as Object to contain the data.
What I have not been able to figure out is how to access the rows of data (in the package variable) from within a data flow task. There does not seem to be a data flow source task to perform that operation.
