Integration Services :: Get Data From Source By Executing Set Of Queries That Have Temp Tables
Jul 29, 2015
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 have one small requirement.. I want to load the different types of files(.txt, .csv, .tsv, .xlsx).
Using one forearch loop container how can I load the files to database and I shouldn't use the script task to split the filenames. Is there any other way to load all the files using forearch loop container, exesql task..
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'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'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.
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 have a requirement to compare data between two tables in SQL Server.
What is the fastest way to do it using SSIS? There are approx 6~7 millions of records in each table.
My solution: Read both the tables and store the data in Object Type variable. Then run an except query. But I am stuck at except query part. How do I implement it?
I have a got a package with source as sql table which has got 50 columns. We are using only 10 columns out of this. Recently one column name has changed and thus throws error invalid mapping. When I open the source to do the changes noticed that all the colums are prselected now and also the datatypes got changed to default ( I had changed the datatypes as per my requirement while i developed). So now I had to select required columns from source and redo the datatype changes in advanced editor.Is there any option which doesnt disturb this settings and we just need to correct the mapping alone.
I am going to set up a new SSIS package that will import data into 5 different tables on a SQL Server database. The source of the data is on another SQL Server and I will use to select the data. If one of the tables fail to import I do not want the SSIS package to import any of the data.What is the best way to create this package? Is it best to create one SSIS package, with five data flow tasks that are linked to each other. Within each data flow task, is a Source and Destination to transfer the data to each table.
I am trying to move a flat file into a temporary table but the pre-execute phase looks for the table and fails the package. Is there away around this? I have set the connection RetainSameConnection to true but that doesn't appear to help in the dataflow.
I have an Integration Services package that loads new data into tables that are dimension tables wi my cube. The same situation exists for my fact table. If I perform an "Analysis Services Processing Task" for the dimensions ,cube and measures, will that move the new data into my cube or do I need to perform the "Dimension Processing Destination" data flow task prior to this? Is the initial processing task good enough?
I would like to export all tables from Oracle 11.2 to MS SQL Server 2012 R1.
Using the tool "Microsoft SQL Server Migration Assistant v6.0 for Oracle" did not work for me because there are too many warnings and errors regarding the schema creation (MS cannot know it because they are not the schema designer). My idea is to leave/skip the schema creation to the application designer/supplier and instead concentrate on the Oracle data export and MS SQL data import.
What is the easiest way to export all tables data from Oracle to MS SQL Server quickly?
Is it:
- the „MS SQL Import and Export Data“ Tool - the “MS SQL Integration Services” Tool - not Oracle dump *.dmp format because it is a propritery binary format - flat file *.csv (delimited format)
I am trying to move data from 8 different tables that are dependent on each other through foreign key relationship.
Basically they have millions of rows in each table and they have data for the past 5 years. I want to move data for the past 120 days and move it to 8 new tables in the same database. So I created the new tables along with their relationships. Now I need to move in the order (parent table first).
The child table has 50million rows data to move The intermediate tables have 10 mil 10mil 10mil and 40 mil 50mil and 20 mil rows to move The parent table has 10 mil rows to move
if I choose to move this data through an SSIS package what is the best way? Or is there a better way to move this data faster?
I will be doing this move only once. After that I have maintenance purge jobs that will cleanup data on a daily basis.
We have a complicated select query that needs to build a couple temporary work tables that are then used in the final select statement (in an OLEDB Source data flow control). We can click preview and see the resultset, but if we click on the Columns view there are no columns. We can save and close the OLEDB Source control but downstream from it there are messages saying that there are no input columns. The T-SQL looks something like this (abbreviated):
SELECT fieldlist INTO #temp1 FROM table
SELECT fieldlist INTO #temp2 FROM table
SELECT fieldlist FROM table INNER JOIN #temp1 INNER JOIN #temp2
DROP TABLE #temp1; DROP TABLE #temp2
Has anyone been able to use temp tables in a source SQL statement in a data flow? Are we doing something wrong or incomplete?
I am transferring data from Oracle tables into text files, and facing these errors.
1. I have a varaible working as an expression and my query goes into that variable and onwards that variable is passed to dataflow task, which parse the query. my query is simple saying "Select * from PLS.ABC" where PLS is my schema, but the task generates error "Opening a rowset for "Select * from PLS.ABC" failed. check that the table exists in the database. and surely the table is there.
2. I have a foreach loop that iterates through all the table names and the table names are passed onwards to the varaible query, the dataflow task inside the foreach loop gets the variable query and will generate text files based on tablenames which i have supplied in another variable to the connectionstring property of the flatfile destination. Is it possible or not. all the tables have different columns and i need the output in text files.
I have a text file which has rows 7 rows.I want to insert the data into SQL table using ssis In text file we have a column which has values as Y or N...I wanted to take only those rows which are Y...But we have only 6 rows in SQL table.It does not have the column with Y or N.
My Requirement ,In Source Database 5 tables are there ( Emp,Loc,dept,Time,Product ), Destination is Single Excel file.But Dynamically how to load each table information to load into each sheet wise through SSIS Package?
I created a SSIS package which loads CSV into database. The package is called in a C# console application which is set as scheduled task in a server. The problem I having is that the package hangs during validation stage: "Truncation may occur due to inserting data from data flow column "Reading Type" with a length of 50 to database column "ReadingType" with a length of 2."There is no problem loading same data from development machine.
I've developed SSIS package and able to Launch and Execute dtsx package using Web Service/Console application. If I run it from my local it has no issues. If I ask my client to run this web service it is throwing error "Unable to connect to remote server".
If I ask my client to directly run the package itself they get following error "AcquireConnection method call to the connection manager failed"...
Even after my client having SQL Server, Integrations Service and BIDS installed on his machine he gets the above error. How to set this up. SQL Sever Agent is not an option for us.
It's SQL 2008 R2. I need to bring data from Oracle using .Net Providers/ODBC Data Provider to MS SQL table converting Oracle UTC dates to PST. The source connection type cannot be changed as it's given. For the Destination I'm using the OLE DB.
As the truncate all and load could take time I'm trying to use a temp table or a variable to use it further with t-sql merge or not exists to bring/add the only new records to the destination table.
I'm trying different scenarios that is all failed.
Scenario A:
1. In DTF after OLE DB Source I'm using the Derived Colum to convert dates. It's working well.
2. Then use Recordset Destination with an object variable User::obj_TableACD. It's also working well.
3. Then I created a string variable with a simple query that I could modify later "select * from " + (DT_WSTR,10)@[User::obj_TableACD] trying to get data from the recordset object variable but it's not working.
Scenario B:
1. Created a store procedure to create a temp table.
2. Created a string variable to execute SP str_CreateTempTable: "EXEC dbo.TempTable". It's working well with the SQL Task with SQLSourceType as Variable.
3. Then how to populate the temp table from the Oracle source to bring data into the Destination?
I have a transaction table having about 40 crore rows in source. It don't have timestamp and unique key columns. It have only Bill_month and Bill_Year columns. Actually for loading this table into staging I have added a new datetime column by adding default bill_date as 01. Then
* First we delete last 3 month data from staging tables. * Get last 3 months data from source table. * Load that 3 months data from source to staging table.
We do this because we only get update for last three months data. Now I have to include this transaction table as Fact table in DW. What will be the best practice for loading the fact table by picking data form staging table. Also we have to look up with dimensions for Foreign Keys.
* Should I implement the same method of deleting last 3 months records and loading them again.
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.
We are using SQL Server 2014 and SSDT-BI 2013. We have a reporting environment where business users create objects which need to be persisted for fiscal year reporting. Let's say for instance SQLSERVER1SRVR1 they create table objects like below in the reporting environment.
Accounting2014, Accounting2015 in AccountingDB; Sales2014, Sales2015 in SalesDB; Products2014, Products2015 in ProductsDB; Inventory2014, Inventory2015 in InventoryDB etc....
These tables are persisted for auditing in a different environment SQLSERVER2SRVR2 for finance & audit folks.We would want to automate this process using SSIS to create tables in corresponding database and load data. I tried using For Each Loop container but the catch is I could loop the source or destination but how do we loop on Source & Destination at the same time (i.e when source is in AccountingDB destination to be AccountingDB, source SalesDB then destination SalesDB so on etc....
