Integration Services :: Iterating Over Object In SSIS With Fix Number Of Results Each Time
Aug 11, 2015
I've got this issue with a query in SSIS. From a table in SQL Server I'm getting over 25000 different identifiers. These identifier are associated to many values in a table in one Oracle Database. This is the schema that I have implemented for doing this.
The problem is that some days the identifiers can be over 45000, and at this point perform a loop for every one is not the best solution (It can take to much time to get the result). Previously I have performed another query where from the SQL statement.
I am creating and sending a unique row with all the values concatenated and then I have recover this unique string from an object and use it to create the query in the ODBC Source that invoke the table in Oracle: something like this:
'Select * from Oracle_table' + @string_values
with @string_values = 'where value in (........)'. It works good because the number of values is small enough to be used, like 250. But in this case I can not use this approach because the number is really big and obviously the DBA of Oracle is going to cancel the query.
So I wonder, how can I iterate over the object getting only a few number of values everytime, something like 300 or maximum 500, to avoid the cancellation of the query but at the same time doing the minimum number of loops.
I am trying to load previous days data at 3 am via a SSIS job.
The Date variable is initiated as DATEADD("dd",-1, GETDATE()) in the for loop.
Now, as this job runs at 3 am, and I set the variable as GETDATE() - 1, it excluded the data from 12 am to 3 am in the resultset as Date is set as YYYY-MM-DD 03:00:00:000 I need this to be set as YYYY-MM-DD 00:00:00:000
I have one scenario. I am calling all columns result set to an variable and inside for each loop container using script task to get message about how many columns are coming in the loop.
At last using send mail task to send automated mails to group of people,but issue it is taking only person's mail id and coming out of loop.
When i use single object variable to pass it to two sequence container having 2 different Foreach ADO Enumerator; seems like the scope of the variable is completed once sequence container 1 is done and second fails with below error
Foreach ADO Enumerator Error: COM error object information is available. Source: "ADODB.Recordset" error code: 0x800A0BCD Description: "Either BOF or EOF is True, or the current record has been deleted. Requested operation requires a current record.".
Does we have to set any property so that object variable scope persist until both loops are completed.
It works fine if i push the data to 2 different object variables.
I built a small package two years ago that uses Flat File Sources to copy in small text data files. Each source connection object has a UNC path to flat text files on another server. The source system changed, so I opened the package and updated the UNC path in one Connection Manager object, and clicked OK. The Flat File Source Editor that uses this source seemed to be able to see the new location when I clicked "Preview". Then I went back to the file source, and the connection had reverted back to the original one. it would not save the new UNC path.
I am using SQL Server 2012 SP2 with SSDT (run as admin). I closed the package in SSDT, edited the connection strings using XMLnotepad, and was then able to open, test, build and deploy the package.
It seems that the Source object will not let itself be changed. The other option is to delete it and recreate it, but I didn't want to remap the fields.
I've created a SSIS package which takes a matrix from Excel file and insert into SQL table. It works perfectly! However, if I would add a new column into that matrix in Excel. Unpivot tool should take into process dynamically. Is there a way to provide this automatically?
For each row coming out of my data source, I would like to add the result of an Oracle query to it (select sequence.nextval from dual).
I need to acquire the sequence number before all my processes in my data flow, so I don't want to have a trigger in Oracle call nextval and do it automatically for me.
I also think getting the value of nextval inside of a variable at the beginning of the process would not work because it only increments the value once.
In SSIS, I created a flow and within that flow i need to create an automatic number generator. The flow is simple: Ole db source part, a multicast part and a flat file destination and a ole db destination. In the Ole db source there is no field that is the starting point for this generator. This automatic nr should start with 10000 and each time a row is found it should be increased by 1.
First question: is it possible to create a column in SSIS flow which is the starting point for the generator (in this case 10000) or should it be created in the source table?
Second question: where in SSIS and with what component can i create such a generator??
I'm executing Oracle procedure, which has three OUTPUT parameters and returns results in table type variable. i should not use ODBC, MSDAORA providers to call the procedure. So I'm planning to using Oracle OLEDB provider. I'm able to execute the procedure successfully, but when i do check (while dr.Read()) its not returning any records. But I know as per stored procedure results, it should return 66 records.
Dim conn As New OleDbConnection Dim cmd As New OleDbCommand Dim dr As OleDbDataReader Dim QSQL As String
I have a stored proc that is returning the results I need for output to .txt file.
Is there a way in SSIS to commit 50K (or whatever number) row batches at a time or should I just handle this in the stored proc?
select * into #TempTable from SomeTable [WHILE LOOP] --throttle commit batches of 50K rowcount select * from #TempTable [END LOOP] drop table #TempTable
But If I'm doing this in SSIS, I can't drop the #temp table otherwise I have nothing to output right?
I am getting below errors when I try to import data from csv format to a sqlserver table.The csv file has date column that has date with format: 7/10/2015 1:18:39 PM and the sql server is using datetime not null for that field in the table.

I am new to SSIS. I have been struggling with this for the past one week. I have a weird task. I need to import several tables from one database to a different server with a new database name. We need to do this at the end of every year. The main problem here is that the number of tables varies every year. You may not have all the tables as last year or may have more tables. So I need to create a dynamic task that takes care of this every year without changing the package.
I have performed the following tasks **
1. Create a new dynamic database. ( I have used Execute SQL Task to do this) 2. Copy all the table structures ( I have used Execute SQL Task to do this)
3. Import Data. This is the main problem. I was trying to create a dynamic connection string with variables as suggested in several forums but I finally came to know that this cannot be done if the table structures are different as the metadata cannot be refreshed at runtime.
4. The final step to create a process to validate the data (the count from each table for both source and destination. I think this can be done with Sql task.
What is the best method to do this? My DBA does not like “Transfer SQL Objects Task” or “transfer Database Task”. I would like to create this as a dynamic process.
I am using SSIS 2012 SP1 to import a comma delimited csv file into a SQL table.
One of the fields carries a time value:
Source = textfile, column=DT_STR(8), value format = "hhmmss", e.g. "011525" Destination = field in SQL table, data type = time(0)
To get it from the textfile to the SQL table I am:
1.) Creating a derived column called [d_Time of Entry]with the following formula -
SUBSTRING([Time of Entry],1,2) + ":" + SUBSTRING([Time of Entry],3,2) + ":" + SUBSTRING([Time of Entry],5,2)
2.) Performing a data conversion task to convert [d_Time of Entry] from DT_STR(8) to time(0) The upload fails because values that start with a zero, i.e. times before 10am, have their leading 0's stripped before being derived. You can see this because "011525" is derived as "11:52:5" when it should be "01:15:25".
Just installed VS 2005 & SQLServer 2005 clients on my workstation. When trying to create a new Integration Services Project and start work in the designer receive the MICROSOFT VISUAL STUDIO 'Object reference not set to an instance of an object.' dialog box with message "Creating project 'Integration Services project1'...project creation failed."
Previously I had SQLServer 2000 client with the little VS tool that came with it installed. Uninstalled these prior to installing the 2005 tools (VS and SQLServer).
I'm not finding any information on corrective action for this error.
Trying to move data in Sybase IQ from one database (prod) to qa for a table. Using ADO.NET connection and just one Data Flow task , source , destination. Using Sybase IQ driver.
Error:[ADO NET Destination [2]] Error: An exception has occurred during data insertion, the message returned from the provider is: Unable to cast object of type 'System.Decimal' to type 'System.Char[]'.

Using Task SQL, I am trying to pass these email addresses to two separate variables - To_field, Cc_field on basis of the CC_Flag..Is it possible to fill two variables from a single SQl Task,.
I have a object variable named "UserList" which gets populated through execute sql task - stored procedure.I wish to concatenate all the values in "UserList" using ssis script task - in lang vb.Output should be like (User1,User2,User3,....)
I am developing a table driven ETL system, where I store large PL/SQL queries in a varchar(max) field. I read the field into an object variable at the package level using a SQL task. Next I have a C# script task that creates a connection to our Oracle database using the Oracle provider. I am trying to set the Command.Text property to the PL/SQL statement I've stored in the package level object variable, but I'm having difficulty getting the Pl/SQL text back out of the object.
I've tried Object.value.tostring, but it just returns a generic "system__text". how I can proceed?
In my ssis 2012 package, I have a 'object' type variable with some table like records. I want to do some SQL operations like insert/update on the records in another table based on this 'Object' type variable records. Basically I want to use a MERGE statement with another physical table with the records in the 'Object' type variable.how to map/use the Object type variable in Execute sql task.I am not good in script task. How to utilize this Object variable in a Execute sql task?
I have a SSIS package where im importing data from MS access database file .MDB. I chose Microsoft JET 4.0 OLEDB provider. When i select a table and preview the data, im getting the below error.

We have a requirement to produce adhoc Excel reports with a standardized header page with a disclaimer attached. We want to be able to feed in a SQL Statement, or a table with the resultset from a SQL Statement and have SSIS populate an existing blank Excel workbook, which the disclaimer attached. The use of xp_cmdshell is not an option.I've spent a lot of time looking for solutions on the web and it seems though its not possible - although many articles are 3-5 years old. Before I throw in the towel, I just wanted to get feedback from this group if it still is not possible in the latest versions of SQLServer and SSIS, or to ask if there are any other 3rd party solutions that can do this today.
I want to achieve the following in (SSIS/SSDT for SQL 2012) -
I have a generic SSIS package which simply sends out email notifications using SMTP email task (this package is within its own project, and has project level input parameters).
I need to be able to call this package in the Event handler section of every package (numbering in about less than 60) that we have. These packages are within their own respective projects.
I thought I could use the "execute package task", but it turns out , using this, I cannot call a package that is part of some other project. I also cannot call a package that is stored in the CATALOG. Is there any way I can do this ?
When I call the child package , I should be able to send in parameters like - error information and package name of the Parent package.
I'm trying to use SSIS in MSSQL 2012 to extract data from MAS90 database.The connection string is tested to be working, because I can extract successfully using the same one in Excel.I follow the wizard of import data in management studio, but after selecting the tables and mapping all those things, when clicking finish, the management studio always freezes.
I have a transformation where final result set give me 25 rows of data. Now before I put into destination table, I need to add another column which will show how many total records we have. Like.
My dataset:
A 20 abc B 24 mnp c 44 apq
Now I need to add another column within my transformation before I store the result set to destination like this:
A 20 abc 3 b 24 mnp 3 c 44 apq 3
Here. new column gives count of total rows in our dataset which was 3.
How can I achieve this? Can I use derive column to this?
I am importing a text file with a column (serial numbers) with alphanumeric data, some mixed and some only numeric. The very large values that are all numeric are being converted to exponential when I run it thru an import package in SQL Server Integration Services (2005)
Ex. 4110041233214321 --> 4110040000000000 (displays as 4.11E+15)
In the past I dealt with this by importing the text file into Excel and changing the format of the column to number. This works even when many of the values contain alpha characters. I am not sure how to accomplish this same thing without going thru Excel. If you have any ideas on this I would be happy to hear from you.
I'm trying write a reusable script component that takes data from rows that were rejected from a SQL Destination operation and put them into a common SQL error table.
This script would basically function to take the input columns selected in the script, and build a delimited string, (similar to the 'Flat File Source Error Output' that is contains redirected rows from reading a flat file) and insert this string into a SQL table called 'SourceData' to store errors.
I'm trying to script the component to iterate through all input columns (as selected in the input columns screen) and build a simple string.
Code Block Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer) 'Use the incoming error number as a parameter to GetErrorDescription Row.ErrorDescription = ComponentMetaData.GetErrorDescription(Row.ErrorCode) Try
Row.ErrorColumnName = ComponentMetaData.InputCollection(0).InputColumnCollection(Row.ErrorColumn).Name Catch ex As Exception
Row.ErrorColumnName = String.Concat("Column Name retrieval failure. Details", ex.Message) End Try ' 'Build input data ' Dim inData As String
For Each inputCol As IDTSInputColumn90 In ComponentMetaData.InputCollection(0).InputColumnCollection inData = String.Concat(inData, "~", inputCol.Name) 'I don't want the name, but the value. Next Row.SourceData = inData ' End Sub
I've only got as far as iterating the names of columns in the input buffer, but how do i get the values?
The result i'm trying to achieve is : Selected columns in 'Input Column' screen : Name, Address, Phone OutPut column 'SourceData' value : Harry~Melbourne~None
I want to load flat files into a single table. But the flat files can have variable number of columns upto a maximum of 10 columns. The table in my database has 10 columns in it. So in case if I load a flat file having 6 columns then rest of the columns in the table will have nulls. I don't want to use script task for this as I am not good in writing C#code.
I am in between of creating a dynamic SSSIS package which will run for multiple zones having different source connection.My source is in Oracle.I am having 3 DFT with the 3 different source tables.I want to create a package with above DFT dynamically so that my single package can run for the entire zone with dynamically source connection change.I have created a Master table which stores the zone source connection string and zone name. I have 2 different connection.so if in future any new zones come so only newly zone details need to be add in master table without opening the package.
