Integration Services :: Compare Source And Target Data Using Conditional Split
Aug 12, 2015
I'm encountering a very peculiar situation when I'm trying to compare source and target data using conditional split. Following is the Data Flow and how I'm trying to achieve this.
Source Data : Col_A (PK) Col_2
1 100
8 500
Target Data : Col_A (PK) Col_2
1 100
3 700
8 500
Look-up Target on Col_A to check for existing records. Now we have four columns in Look-up match output: Col_A, Col_B, Lkp_Col_A (Target Col), Lkp_Col_B (Target Col).
Conditional Split: Compare Col_B with Lkp_Col_B
Update target if there is any change in the existing value of Col_B.When I'm running the package for every record in source, the conditional split fails and even when there is no change in Col_B, some of the records (Not all and quite randomly) get updated with the same value. If I run the package for few records, it works absolutely fine.
I am importing the values for field Atype from a .csv file as DT_STR, 13 and I need to fit them into a bit type CType field.
When I write the conditional split ((ISNULL(Atype)?"a":Atype)!=(ISNULL(CType)?"9":CType)) it says that the DT_WSTR and DT_I4 types are incompatible and that I need to explicitly cast with a cast operator. I haven't been able to make it work, how to explicitly cast?
I'm trying to write a conditional split where I want to bring in only records where the date is less than today, but my problem is that I can't simply do this Column < GetDate() because if something comes in today, it takes the time into account and it will bring that record for today. You can do this in SQL, but I'm not sure how to do that in SSIS
I have a Problem with my destinations. I have a split condition with two ways the flow can use.
In this case: all and Date.
All and Date can be set by using a variable. Its working good.
When a user fills the variable with a date value (cast to string) the conditional split executes the correct flow with all the needed rows... The same time the all flow will be executed with 0 rows. In the end the destionation file for the all values will be overwritten with nothing. The same on the other hand when a user fills the variable with the all value, the date file is empty. What can i do to make sure that the files are not empty?
We are building a dataload application where parameters are store in a table. And there are multiple packages for each load.There is a column IsChecked column if it is 1 then only the child package should execute.Created a master package. In which i have taken execute SQL task in that storing a results in variable and based on the result the child package should execute. But In executesql task i selected result set as full result set. I am getting the below error.
[Execute SQL Task] Error: Executing the query "SELECT isnull(ID ,0) AS ID FROM DataLoadParameter..." failed with the following error: "The type of the value (DBNull) being assigned to variable "User::LoadValue" differs from the current variable type (Int32). Variables may not change type during execution. Variable types are strict, except for variables of type Object.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
If I have 2 input fields to my conditional split, how can I do a compare based on if they are alike. Example, I have 2 IDs, I want to see if the IDs match for a PK/FK relationship, if they match, then output those rows to the conditional's output stream. Do I literally do this or is this not right for the expression? Is there a like statement I should be using instead?
[IDName] == [IDName]
Basically I have 2 OLE DB sources coming in, 2 sets of columns, and both tables behind each OLE DB souce have an ID field to determine the PK/FK relationship. Out of all the records going through from the OLE DB source to the conditional split, I want to output each set of records where the IDs are equal...thuse after my conditional split, I could then take those records and input them into another txt file....and then the process would repeat for the next records in the pipe where IDs are the same...
My objective is to extract the source table data from SQL/Oracle or CSV files and load into destination table using CDC mechansim. May I know the steps required to implement in production from development.
Right the answer is probably simple but the Internet and books and everything has been no joy to me whatsoever.
I want to split my data stream based on the date. So I want to use a conditional split object to do this.
I entered the following as my case date_created > (DT_DBTIMESTAMP)"01/10/2000"
When I move off the line it stays black so appears to be okay, yet when I run my package it says it is not a boolean result and fails. Can anyone please tell me what I am doing wrong.
Also I cannot filter in the source call due to the sheer amount of work being done on the data before the split.
I am using DTS and VBScript in DataPump tasks in order to transfer large amounts of data from text files to an SQL database.
As the database uses a normalized schema, there is often the case of inserting multiple records in a destination table from various fields of the same record of the source text file.
For example, if the source record contains information about goods sold like date, customer, item code, item name and total amount, and does so for a maximum of 3 goods per sale (row), therefore has the structure:
I have tried using a datapump task and VBScript, and I guess it has to do with the DTSTransformStat_**** constants, but none of those I used seems to work
Im reading in a CSV wiht double quote text delimiters. Data came from mySQL.
One column in mySql is text(65535) which is equivalent to varchar(max) as far as i understand.
This particular column can be blank, not null, just blank. If its blank i want to put in a value so i added a Derived column shape and added the following formula:
LEN(my_Column) < 1 ? "" : (DT_TEXT)my_Column
I get the below error from this expression:
The data types "DT_WSTR" and "DT_TEXT" are incompatible for the conditional operator. The operand types cannot be implicitly cast into compatible types for the conditional operation. To perform this operation, one or both operands need to be explicitly cast with a cast operator.
I have tried this without casting but still get an error. As I have configured the column in the flatfile connector as DT_TEXT, im not sure where its getting DT_STR from.
I have a delimited text file with 650+ columns. The sum of the column lengths of a single row, if fully populated, exceeds 30K bytes. The "killer" fields lengthwise are the "Description" fields. If they were removed from the input file, the remainig columns would occupy about 5000 bytes, which is within SQL max row length.
Can SSIS be used to created these two tables? (one without description fields, the other with those field but arranged vertically in the table rows).
The fundamental issue is I can not import a single file row into a sql table because that row length could exceed the max byte count for a row.
I've got a problem to retrieve data from a Xml Source. Basically, I call a method from a Web Service which gives me a Xml file.
The problem is that the XML structure is not really good. But we can't touch it.
Here is the Xml File :
Code Snippet
<?xml version="1.0" encoding="utf-16"?> <ArrayOfWSTargetVO xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <WSTargetVO> <ProjectId> <Value>131</Value> </ProjectId> <Id> <Value>Toto</Value> </Id> <Name> <Value>bateau</Value> </Name> </WSTargetVO> <WSTargetVO> <ProjectId> <Value>131</Value> </ProjectId> <Id> <Value>Tata</Value> </Id> <Name> <Value>F35</Value> </Name> </WSTargetVO> ... </ArrayOfWSTargetVO> As you can see, for each WSTargetVO, we have a projectid, an id and a name. But the value is not directly put into these nodes but in a new one : <value>
That causes my problem because here is the xsd file generated by visual studio :
Code Snippet
<?xml version="1.0"?> <xsd:schema xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsd="http://www.w3.org/2001/XMLSchema" attributeFormDefault="unqualified" elementFormDefault="qualified"> <xs:element name="ArrayOfWSTargetVO"> <xs:complexType> <xs:sequence> <xs:element minOccurs="0" maxOccurs="unbounded" name="WSTargetVO"> <xs:complexType> <xs:sequence> <xs:element minOccurs="0" name="ProjectId"> <xs:complexType> <xs:sequence> <xs:element minOccurs="0" name="Value" type="xs:unsignedByte" /> </xs:sequence> </xs:complexType> </xs:element> <xs:element minOccurs="0" name="Id"> <xs:complexType> <xs:sequence> <xs:element minOccurs="0" name="Value" type="xs:string" /> </xs:sequence> </xs:complexType> </xs:element> <xs:element minOccurs="0" name="Name"> <xs:complexType> <xs:sequence> <xs:element minOccurs="0" name="Value" type="xs:string" /> </xs:sequence> </xs:complexType> </xs:element> </xs:sequence> </xs:complexType> </xs:element> </xs:sequence> </xs:complexType> </xs:element> </xsd:schema> And when I try to use the outpul results from the Xml file, I can't see how I can get a datatable with three columns corresponding to projectid, id and name.
Integration Services only asks me to choose between WSTargetVO or ProjectID or Id or Name and give me the <value> value.
I don't know if it is possible to modifiy the contents of the XmlFile or something else using XPath.
Of course, if I try to modifiy the XSD file and delete the value node to have a simple structure, I see my three columns but i can't get any data.
I'm aware that the XML file is pretty bad but it is impossible for me to change it.
If somebody has an idea, I would be happy to hear it :-)
I have ssis package that pull data from SAP (Using ADO.net connection) to SQL server every night but i have noticed that all data from source is not getting pulled by package . package losing some amount of row.
I am able to collect data from Progress DB, using ODBC Connectivity. The problem I am facing is, i have to iterate thru multiple servers. How do i configure ODBC source dynamically. It creates problem. Using expression, i tried to set the connectionstring dynamically, but it fails.
After designing a SSIS package in Visual Studio 2005 that had two connection manager defined to keep the password. After I deployed the package to a file system. I then Imported the .dtsx file after making a Integration Services connection in Sql Server Management Studio. When I tried to run the package it failed when it tried to make the connection. When I edited the connection manager connection string and added the password and the package ran fine but it does not retain the password!. I need to have this package scheduled to run daily so I need to know how to have the package keep the password in the connection string. I have seen other posts on this issue but not seen a good solution. Could someone point me to the proper MSDN article that would explain how to implement this ? Is it a SQL Server configuration issue or a property in Visual Studio SSIS design time ?
I need to grab data from teradata(using odbc connection).. i have no issues if its just bunch of joins and wheres conditions.. but now i have a challenge. simple scenario, i have to create volatile table, dump data into this and then grab data from this volatile table. (Don't want to modify the query in such a way i don't have to use this volatile table.. its a pretty big query and i have no choice but create bunch of volatile tables, above scenarios is just mentioned on simple 1 volatile table ).
So i created a proc and trying to pass this string into teradata, not sure if it works.. what options i have.. (I dont have a leisure to create proc in terdata and get it executed when ever i want and then grab data from the table. )
I am very new to XML file area in ssis, need to load several files into one DB . Details requirement as below.
- XML file is loaded into DW_EXTERN, and then moved to the archive with a time stamp suffix. --I Know how to move this to Archive folder but i need to move with today's (execution)date, how to do this?
- Loading should be done with usual logging using batches etc. --Done
- We will receive one xml file per day containíng all changes since the previous file. The file is date stamped, showing the period of time the file contains.
- Initially we will receive 700 files (2 years of data). The package must support more than one file in the input queue, and able to load them in the correct order. -- using for each loop to loop thru all files ?As per my knowledge files will sorted and stored in a folder with date modified so, those will get executed in that order, right?
- The package must be able to reload a period. Delete all future records compared to the current file before loading the file. -- Need to delete > source file date from target table and load the file
Here, i have couple of doubts.
1) How to select source file name with date modified value from source folder using For each loop
I have a custom SSIS Script task (c# code) which , using WINSCP secure FTP libraries, downloads files from an FTP server to local folder.This works perfectly fine on my personal machine.But when I deploy the project on to Catalog, and try and run the same SSIS package using Agent Service , I get this error - "Exception has been thrown by the target of an invocation."
The Service account used to run the package (on the server) has all the needed permissions to write into the folder on the server.
I'm using a shared data source to connect an Oracle server in my packages. After changing the database user password in the shared data source, I noticed the package concerned would fail with the following description.
All examples I found refer to classes under Microsoft.SharePoint namespace. However, I have the SharePoint CSOM that only gives me the Microsoft.Sharepoint.Client namespace.
I need to read the selected values of a multichoice field, but not sure how to do it with classes in the namespace above.
everthing works, exept the TSQL_x0020_Reference_x0020_Numbe field.
I am working to archive some old data from a data warehouse using SQL server and SSIS. The data will be read and denormalized, then shipped out to a delimited text file.
The rowcount of the incoming data is significant, call it 10M+ rows per unit of work (one text file).
There are development advantages of using a stored proc for the data source - mainly ease of changing the denormalization logic as required. Wondering if there are performance advantages of an embeded query for the data source instead?
It was mentioned by one developer that when using a stored procedure, the output stream from the proc and subsequent SSIS steps cannot start until the full procedure processing is complete; i.e. the proc churns out its' result set in one big chunk.
He hinted that an embedded query does not have this same effect, but I am not sure that is accurate.
I have a package which has an Excel source with the 'Data access mode' set to SQL command and then a sql select statement. When I try and hit the 'Preview...' button below the 'SQL command text' window I get the following error:
"Error at Standard Data Flow Tasks [source tasks name]: No column information was returned by the SQL command"
Ordinarily this would be down to the fact that my SQL is shocking, I hit the 'Preview...' button whilst the workbook the source is pointing at was open and it works fine??
I can't figure this out, but needless to say the package errors with a NEEDSNEWMETADATA when I try and run it.
've got an execute task that take data from a simple table ,I set up the variable Passing as object and I pass the variable to a For Each loop container..
I call the variable in the for each loop container and using the script VB I try to msgbox the variable but it gives me the error:
exception has been thrown by the target of an invocation.
I'm using SSIS 2005 Enterprise edition, I'm creating a package that reads an excel (xls) file using the "excel source" component, and it dumps the data into an OLEDB destination (a sql server). When I drag the excel source component and create the excel connection to my file the component automatically reads the columns and their datatypes.
The problem is that I have a column which has numeric data and the package uploads as NULL every number that starts with a zero. (note: in excel this column is formatted as "text", despite it has only numbers, because it's the only way excel maintains the left sided zeros).
So I checked the data types by right clicking the excel source component -> show advanced editor and my surprise is that this column's data type is detected as double-precision float, and it doesn't let me change it. URL... but it only works when the first row of data has a number beginning with zero on this column. How to get the data imported correctly?
We have a single generic SSIS package that is used to import several hundred iSeries tables into SQL. I am not looking to rewrite the process. But I am looking for ways to improve performance.
I have tried retain same connection, maximum insert commit size, lock table (tablock), removed some large columns, played with the log file location and size, and now I am working to tweak the defaultbuffermaxrows.
To describe the data flow task - there are six data flows tasks (dft) working at the same time. Each dtf has their own list of iSeries tables and columns and the corresponding generic SQL table names. Each dtf determines their list of tables based on the number of columns to import. So there is dft30 (iSeries table has 1-30 columns to import), dtf60 (iSeries table has 31-60 columns to import), etc. The destination SQL tables are generically called Staging30, Staging60, etc. Each column in the generic Staging tables are varchar(100). The dtfs are comprised of an OLE DB Source and an OLE DB Destination.
The OLE DB Source uses a SQL Command from Variable to build a SELECT statement. The OLE DB Source uses a connection manager that uses an IBM iAccess IBMDA400 provider. The SQL Command ends up looking like this for the dtf30. This specific example is importing from the iSeries table TDACLR and it only has two columns so it will be copied to the Staging30 table.
select TCREAS AS C1,TCDESC AS C2,0 AS C3,0 AS C4,0 AS C5,0 AS C6,0 AS C7,0 AS C8,0 AS C9,0 AS C10,0 AS C11,0 AS C12,0 AS C13,0 AS C14,0 AS C15,0 AS C16,0 AS C17,0 AS C18,0 AS C19,0 AS C20,0 AS C21,0 AS C22,0 AS C23,0 AS C24,0 AS C25,0 AS C26,0 AS C27,0 AS C28,0 AS C29,0 AS C30,''TDACLR'' AS T0 from Store01.TDACLR
The OLD DB Source variable value looks like the following, but I am not showing the full 30 columns
select cast(0 AS varchar(100)) AS C1,cast(0 AS varchar(100)) AS C2,cast(0 AS varchar(100)) AS C3,cast(0 AS varchar(100)) AS C4,cast(0 AS varchar(100)) AS C5, ... cast(0 AS varchar(100)) AS C30.
The OLE DB Destination uses OpenRowSet Using FastLoad From Variable. The insert into Staging30 ends up looking like this.
Of course we then copy and transform the Staging30 data to the SQL table that equals T0.
But back to defaultbuffermaxrows. Previously the dtfs had default values of 10000 for DefaultBufferMaxRows and 10485760 for DefaultBufferSize. I added a SQL task to SUM the iSeries column sizes, TCREAS and TCDESC in this example, and set the DefaultBufferMaxRows by dividing the SUM of the columns max_length into 10485760. But I did not see a performance improvement. Do you think that redefining the columns as varchar(100) for the insert is significant? Should I possibly SUM the actual number of columns (2) as 2x100 or SUM the 30x100?
I am created a SSIS package to export data. I am exporting query data to a flat file to a different server. I tried to use the UNC path and it failed saying could not access the file. How can I create a SSIS package to export data from one server to another?
I have a SSIS package with Script task ,it performs basic operation of moving files to one location to another .It works fine in VS2012 environment and when i write a SQL job to execute the package ,it fails ,below is the error :
Code: 0x00000001 Source: Script Task_MoveOldFilestoArchive Description: Exception has been thrown by the target of an invocation. End Error DTExec: The package execution returned DTSER_FAILURE (1). Started: 9:54:57 AM Finished: 9:54:58 AM Elapsed: 1.029 seconds. The package execution failed. The step failed.
I'm trying to import data in Excel into SQL Server table which you would think would be an absolute doddle seeing as they're both key Microsoft products in the BI family..One of the columns in Excel spreadsheet is Comments1 and a couple of the values in this column are over 300 characters in length yet when I set up the Excel source and then open Advanced Editor and look at Input and output properties this column has a data-type of Unicode string [DT_WSTR] with length of 255 which leads to the truncated error in the title.
I've researched this and on find going into the registry and updating the TypeGuessRows value from 8 to zero. I've done this and yet the data-type is still showing as Unicode string [DT_WSTR] with length of 255. I've even moved the row with the largest number of characters to the top of the spreadsheet and changed the TypeGuessRows value to 1 but the data-type still stays the same.I can't believe that it's soooo difficult to import data from one of Microsoft's key BI applications to another using their 'world-class' integration tool.
