How to create a new table dynamically in OLE DB destination.
This is what i am doing
I am reading multiple flat files in loop and saving file name to a variable. Then i have a source script component which read and transforms data .Now how can I push the data to SQL table. I want to create a new table with name saved in a variable. I tried using OLE DB destination and assigning table name from variable. Does'nt work.
Thanks in advance for any insight on how to make this work.
I have searched the archives and haven't found a solution that works.
I started out with a package based on the Excel import wizard and have modified it to include a for each loop for processing more than one Excel source file and also modified it to do some dynamic SQL like dropping and creating the tables with names that are variable based. The package is cabable of processing more than one file, and each file has the same data elements or columns in it, but each file has to go in it's own table. The drop and preperation tasks use string variable SQL that does dynamically create the SQL and runs great. The data flow task and it's OLE destination task (which the wizard did intially create) does not perform as expected. There were some posts in the archives stating that for dynamic destination table names it can be done in the OLE destination but I can't get it to work. I tried using an access mode of table/view name variable and select a variable that is string expression based. But this variable isn't fully populated until run time and so when I'm trying to configure this I get a msg stating the table name object doesn't exist and I can't save the task.
Am I doing something wrong, or trying to do something that wrong way or trying to do something that isn't possible?
I have a requirement to take xml file, in case the number of column changes, it should not fail the package, rather it should load the data in destination table. Destination table could be altered separately depending on xml schema by the DB team in production.
I have a requirment which i have partly accomplished , but could not get through completely
i have a file which comes in a standard format ending with date and seq number ,
suppose , the file name is abc_yyyymmdd_01 , for first copy , if it is copied more then once the sequence number changes to 02 and 03 and keep going on .
then i need to transform those in to new file comma delimited destination file with a name abc_yyyymmdd,txt and others counting file counting record abc_count_yyyymmdd.txt. and move it to a designated folder. and the source file is then moved to archived folder
what i have taken apprach is
script task select source file --------------------> data flow task------------------------------------------> script task to destination file
dataflow task -------------------------> does count and copy in delimited format
what is happening here is i can accomlish a regular source file convert it to delimited destination file --------> and move it to destination folder with script task .
but cannot work the dynamic pick of a source file.
please advise with your comments or solution you have
Hello everybody . I am building DTS transfer data from SQL server into Excel file
source query constant ,but destination will be supplied by parameter
At design time I created destination excel file and saved a copy of it like C: empl_excel.xls
presently dts work in following order 1. set datasource of destination from global varaibale(@@X) 2. execute xp_cmdshell to copy C: empl_execel.xls to file in @@X 3.Run transformation
How to eliminate step 2 ? If I run step 1 and 3 ,I get error "table does not exist" How dynamicly create table in excel and map columns for transfer
I am building SSIS for 3 different files that have identical schema and mapping logic.
In my OLE DB Source (object name - "OLEDBSource_SourceTable") Data Access mode is "Variable name". As soon as I swithced to this Data Acces mode it started to give me an error:
[OLEDBSource_SourceTable [1]] Warning: The external metadata column collection is out of synchronization with the data source columns.
The column "DEAL_NUM" needs to be updated in the external metadata column collection. The "external metadata column "DEAL_NUM_Flag" (34529)" needs to be removed from the external metadata column collection. The "external metadata column "recordID" (33740)" needs to be removed from the external metadata column collection.
Is there anyway to dynamically change the Sql Server Destination? Let's imagine i want the data to go to a table based on a specific parameter like year for example...
Imagine tables like table1_2005, table1_2006 and i want to dinamically change the SQL Server Destination so it would insert 2005 or 2006 and so on....
I can't seem to find that option... It was really a good idea for microsoft to implement Expressions in such components... Dynamics it's all about it :)
I am a beginner for the SSIS and would like to know how to modify the OLDEB Destination connectionString property at run time like using "for each loop container".
My requirement is that I have a single source which would be Sql Server 2005 and my destination is in MS-Access database residing in 100 places. I do not want to manually design in the data flow to these 100 destinations.
I have all the destinations stored in a table and would like to pick these destinations from the table and loop through the same at run time by modifying destination connection string.
I have planned using dts but the for each loop container does not work through as it works with flat file connection manager , but does not go well with OLDEB connection.
Say I am going to write to a different Flat File for every product. So if there are 10 products in the data. There should be 10 Flat Files. Also the file name should include the Product Name And Product ID.
It is being done in a single Data Flow Task.
Right now the Property Expression for the File Name is which is not working)
Hello, What I'm trying to accomplish is to have a variable names "SourceTable" and "DestinationTable". So for each SourceTable, the DestinationTable will have the same columns. All I need is to auto-map these columns between source and destination via code?
I need to take 5 or 6 select statements to excel. Here are my limitations...
- each of the queries (thankfully) have the same data format - each of the queries could return more than 65k, so a new worksheet needs to be generated dynamically. - the names of the excel worksheets need to be custom, but a naming scheme would have to be developed for queries that ran over into multiple worksheets.
What's the smartest way to do this?
I'm having a hard time getting my head around this. I would love any help... I know I'm not breaking any new ground here. I've found pieces of what I'm doing on lots of forums, but never the exact thing. The complexities compound quickly when dealing with dynamic excel worksheets. =)
I have a database app, and we're implementing various data export features using SSIS.
Basically, it's a couple of straight extracts of various recordsets/views, etc. to CSV (flat files) from our SQL Server 2005 database, so I'm creating an SSIS package for each of these datasets.
So far, so good, but my problem comes here: My requirements call for users to select from a list of available columns the fields that they want to include in their exported file. Then, the package should run, but only output the columns specified by the user.
Does anyone have any idea as to the best way to accomplish this? To recap, at design time, I know which columns the users will have to choose from, but at run time, they will specify the columns to export to the flat file.
Dynamically load a flat file from a dynamic source table-
The source table metadata is known via the SYSOBJECTS and SYSCOLUMNS tables- I can pull the column names, type and lengths from these tables based on the table name. (my goal is pretty simple- pull data from a table in our database, and save it down to a flat file)
Would this be enough to dynamically create the destination flat file? If so, how do I do it?
I created a data flow with complaicated SQL. There is "type" field in the output column.
I would like to created excel files for each "type" value
E.g. If there is 3 "type" values (A, B, C), I would like to create 3 excel files to store type A, type B, and type C data respectively.
Since the number of possibe value of "type" field is various, how can I create the xls destination dynamic and move the correct type to the corresponding excel file?
The conditional split has fixed conditions, it is not suitable for by dynamic number of value
For Loop condition is not a good choice because I need to run the complicated SQL for many time.
Need to know how I can get the dynamic filename created in the FlatFile destination for insert into a package audit table?
Scenario: Have created a package that successfully outputs Dynamiclly named flat files { Format: C:Test’Comms_File_’ + ‘User::FileNumber’+’_’+Date +’.txt’
E.g.: Comms_File_1_20150724.txt, Comms_File_2_20150724.txt etc} using Foreach Loop Container :
* Enumerator Set to: “Foreach ADO Enumerator” with the ADO object source variable selected to identify how many total loop iterations there are i.e. Let’s say 4 thus 4 files to be created
*Variable Mappings : added the User::FileNumber – indicates which file number current loop iteration is i.e. 1,2,3,4
For the DataFlow task have a OLDBSource and a FlatFile Destination where Flat File ConnectionString is set up as:
I was wondering if there is a way to 'Move File' with the File System Task inside of a For Each Loop container but to dynamically set the Destination path variable.
Currently, this is what I have: FileDestinationPath variable - set to C:TestFiles FileSourcePath variable - set to C:TestFiles FileNameAndLocation variable - set to blank
For Each Loop Container Iterates through a folder C:TestFiles that has .txt files in it with dates in the file name. Ex: Test_09142006.txt. Sets the file path (fully qualified) to the Variable Mapping FileNameAndLocation.
Script Task (within For Each Loop, first step) Sets the FileDestinationPath to the correct dated folder within C:TestFiles. For example, if the text files I want to move are for the 14th of September, it takes FileDestinationPath and appends the date folder to the end of it. The text files have a date in the file name (test_09142006.txt) and I am picking this apart (from FileNameAndLocation in the For Each Loop) to get the folder date. (dts.Variables(User::FileDestinationPath?).Value = dts.Variables(User::FileDestinationPath?).Value & ? Month & _? & Day & _? & Year & ?) which gives me C:TestFiles 9_14_2006?.
File System Task (within For Each Loop, second step) This is where the action is supposed to occur. I want it to take the FileDestinationPath and move the FileNameAndLocation file (from the For Loop) into this folder for each run.
Now as for my problem. I want this package to run everyday but it has to set the FileDestinationPath variable dynamically according to that days date. Basically, how do I get this to work since I cant hard code the destination path variable from the start? I have the DestinationVariable on the File System Task set to the FileDestinationPath variable, after the script task builds it. However, using FileNameAndLocation as the SourceVariable on my File System Task tells me that the Variable FileNameAndLocation? is used as a source or destination and is empty.?
Let me know if I need to clarify further...I may be missing something very simple. Any help would be greatly appreciated!
I am stuck on finding a solution to transpose source data from a system via a metadata look-up table into a destination table. I need a method to transpose/pivot the source data into columns (which are by various data-types). The datatypes for each column are listed in a metadata table.
Source Data Table:
Table Name: Source
SrcID AGE City Date 01 32 London 01-01-2013 02 35 Lagos 02-01-2013 03 36 NY 03-01-2013
Metadata Table:
Table Name:Metadata
MetaID Column_Name Column_type 11 AGE col_integer 22 City col_character 33 Date col_date
Destination table:
The source data to be loaded into the destination table(as shown below):
My DTS package does nothing special it just pulls in an data from another server (specifying the SQL in a Global V).
This data is then altered using various Stored Procedures.
What would be nice is if the data's destination table could be a #temp table (within tempdb) and then my sps could access it and perform their various operations.
At the moment i cannot get this to work and instead all i can think of is to Create a table within the main working db and insert the data into that and then insert the data into a #temp table and DROP the table i created in the working database.
There must be a better way to achieve this. Is there any way to copy the data straight to the #temp table i have created?
Hi, I need to truncate the Destination table every time before the data is loaded. I had checked out in OLE DB Destination properties but couldnt find any information on truncate table.
EXP: In INFORMATICA we have a properties setting for truncating the table every time the data get loaded. Im looking for this option in SSIS can any one guide me on this. Thank you,
Hello, In my Data Flow I have a OLE DB Destination that needs to get the table name to write the data to dynamicaly from a variable I created. So I select "table name or view name variable" from the Data access mode and select my variable below. So far so good, but when I click "ok" I get the following error message :
I have two program (App1 And App2) on two separate system.on App1 there is a database named DB1 and on App2 there is a database named DB2.on DB1 i create a table named Table_1 .i define replication for DB1 to push publication (for table_1) .
I define DB2 as a subscriber to receive all changes on [DB1].[Table_1]. every thing is ok but just one thing. when App1 and App2 both are running if i change the contents of [DB1].[Table_1] this change only shown if one time i exit from App2 and rerun it . how can i refresh App2 without rerun it?
A friend said to me it is possible with trigger, but how? I don't know how can i define a trigger for this reason . or any way that exist for this reason.
I have a data flow task that performs an "upsert" by directing successful rows from a Lookup to an OLE DB Command that updates rows and unsuccessful rows (Lookup error output) to an OLE DB Destination for insertion.
The problem is that execution hangs when both tasks update/insert into the same table (execution is still hung after 20 minutes). Modifying the OLE DB Destination to insert into a different table succeeds (execution completese within 2 minutes). Replacing the OLE DB Destination with a Row Count transformation also works.
Could this be due to a table-locking issue? Any suggestions?
I created a package using the Import Data wizard and everything works fine when I re-execute it. I needed to change the name of the destination table so I went into SQL Server and renamed the table. I then went in and edited the DTSX file via a text editor and changed the OpenRowset setting from [CMBS].[dbo].[raw_Note] -> [CMBS].[dbo].[T_Raw_Note]
<property id="104" name="OpenRowset" dataType="System.String" state="default" isArray="false" description="Specifies the name of the database object used to open a rowset." typeConverter="" UITypeEditor="" containsID="false" expressionType="None">[CMBS].[dbo].[T_Raw_Note]</property>
There are no other references to the table in the DTSX, i saved the file and then re-ran.
When I run, I get invalid object name dbo.raw_Note (old table name). Is there some data being cached somewhere or hidden elsewhere that it would reference the old table? When I go back into the DTSX file, the correct name is in there so I don't know where it is getting the old name from? Any help would be appreciated.
Create a table at the beginning of a package (using a ExecuteSQLTask component) and then use the created table as a OLE DB destination component, later on the package.
Is this possible in SSIS?
The problem I run into is that I have to point the OLE DB destination component to a table and set up mappings, however as the table does not exist until the package is running, it does not seem to be possible.
Which is slightly similar to what I want, but the table I create would not be a temp tables, and I need to set up mappings and I don't see how this is possible.
I have searched the SSIS forum for an answer to my question, and I think I have found my answer but what i have read does not come out directly and answer my question.
I am attempting to create an SSIS package that imports data from a Visual Foxpro table into a SQL Server table. From what I have read, the source and destination tables must match column for column. Is this correct? My SQL Server table has a few more columns in it. However, i consistently get "Cannot create connector. The destination component does not have any available inputs...blah".
From what i have read, it sound like the reasoning is that my source and destination tables do not match.
Is this correct, or am i barking up the wrong tree?
Short Question: How do I delete all records from a destination table prior to appending new data to that table?
I am working with a SQL database that was migrated from MS Access. All relationships, primary keys, and identity columns have been set identically to the MS Access database values. The MS Access database is still being used as the database of record until the SQL database is fully functional with front-end, etc.
I want to delete the information stored in all the SQL tables, and then append the MS Access values to the SQL tables. I was able to write delete and append queries in MS Access to correctly transfer data to the SQL tables. However, I would prefer doing this through SSIS because I have several other sources of data to move to a SQL Server database and most of those other sources are not a MS Access database.
Due to relational entegrity settings, I need to delete the records from 8 tables in a specific order. I have tried independent control objects for each of the 8 tables with data flow objects of either "OLE DB Command" or "OLE DB Source" with the SQL command as "Delete From TableName". Results of the debug indicate everything is "green" but no records were deleted fromt the tables.
Is there any way around (or will there be) using the drop-down? It takes several minutes when running against an Oracle Apps database to populate that dropdown with the several hundreds of tables and views.
I am having a Data flow task in For each loop which will gets 100 sourcetable names and 100 target table names...
am having a simpleData flow task which trasferes from OLEDBSource to OLEDBDestination. I am repeating the Dataflow task which transfers from sourcetablename extracted from for loop to a destination table var.
The problem am gettting is for the first table it is able to transfer correcly because I did mapping for those tables at design time...but for the next coming sourcetable-desttable (which r having different no of cols,datatypes) its giving Validation failed...and...needs to refresh metadata....
is there any way to refresh the metadata of Data flow task (I set the property of OLEDBSource validate external meta to false then also same error is coming)
I used bulk insert to insert a txt file into a table. It works fine. (see code below) Now, one txt file with column's name at first row and has about 200 columns. There is no table created before. How to code to create a destination table based on first row of the txt file so that bulk insert will work for that txt file?
BULK INSERT #MBRACCT FROM 'c:order.TXT' WITH ( FIELDTERMINATOR = '|', FIRSTROW = 2, ROWTERMINATOR = '' )
