I have a flat file with 13K columns which I need to load in a wide table.
The flat file does not even have column names and no datatypes defined.
How to load data in the wide table?
Also if i choose to load the data in 13 different work tables.
How do I define datatypes in the flatfile connection manager in SSIS for 13000 columns ?
we can easily load a file into db tables. However, my main concern here is the number of columns in the file. A text file TEXT_1400.txt has 1400 columns. I am unable to load data to my db table using BCP or BULK INSERT commands, as maximum of 1024 columns are allowed per table in SQL Server 2008.Â
We can still go ahead and create ‘Wide Table’ (a special table that holds up to 30,000 columns. The maximum size of a wide table row is 8,019 bytes.). But when operating on wide table, BCP/BULK INSERT commands still fail. After few hours of scratching my head over BCP and BULK INSERT, I observed that while inserting BCP/BULK INSERT commands are unable to identify SPARSE columns and skip these columns, which disturbs column mapping and results in data conversion and trancation errors.
Â
Is there any proper way to load this kind of files into the db table?Â
I'm loading data from a sql server table into a flat file. The flat file connection manager has the following settings
GENERAL:
Format:Delimited
Text Qualifier:"
Header row delimiter: {CR}{LF}
Header rows to skip : 0
Columns:
Row Delimiter: {CR}{LF}
Column delimiter: comma(,)
Here is my requirement, How to handle using SSIS.
My flatfile will have multiple columns like :
IDÂ key1Â key2Â key3Â key 4
I have SP which accept 3 parameters ID, Key, Date
NOTE: Key is the coulm name from the Excel. So my sp call look like
sp_insert ID, Key1, date
sp_insert ID, Key2,date
sp_insert ID, Key3,date
Hi,
I€™m trying to create a VERY wide table, with 1,000 columns of type varchar(MAX), nullable.
The CREATE TABLE statement (both in SQL 2005 & 2008), gives the following warning:
Warning: The table "WIDE_TABLE" has been created, but its maximum row size exceeds the allowed maximum of 8060 bytes. INSERT or UPDATE to this table will fail if the resulting row exceeds the size limit.
When I insert data into the table, filling all columns with small, 10-byte string values, I get the following error:
Msg 50000, Level 16, State 1, Procedure sp_pivot, Line 118
Cannot create a row of size 15034 which is greater than the allowable maximum of 8060.
I€™d like to verify this observation: each row is created with 2000 bytes of offset data (2 byte * 1000 columns), 125 bytes for null bitmap (1000 columns / 8 bits) and some more €œwasted€? row information. This leaves less than 6K for the data itself. But since not all columns can fit within the page, forwarding pointers in the row need to be created, 24 byte per column, which very quickly add up to more than 8K, thus the error. So the 8K limit is met for much less columns than the max 1024 column restriction.
Furthermore, in SQL 2008, SPARSE columns will not solve the problem (maybe save some €œmetadata€? space in case the columns are null, but if not, I€™m with the same problem again, or even worse, since now each value takes more storage space. The max 30,000 columns in 2008 is only for cases where the column values are really sparse€¦
Is this the right observation? if so, is there a workaround besides splitting to multiple tables?
Thanks,
Aviv.
I'm working with integration services 2008 and I have a package where I selected a certain set of rows from an Oracle database and then I insert this data set into a SQL database. When the package is inserting in SQL database, it shows that all the rows were inserted, "green", but when I check the amount of data (I count), it's not the same as it was in Oracle.
For example: there are 15390 rows in Oracle and the packages inserts sometimes 9801, 8310, 9952, 9934, 9975, 5437, 9909 rows in SQL server.The package does not abort! It simply does not insert all the rows!
I have a ssis package which identifies duplicate records in access database. I have staged access database into sql sever and created ssis package. Now, I have final list of records which needs to be delete from access database and new records which are to be inserted into access database.Â
What do I need to do if I want to delete those duplicate records directly from access database using SSIS. I cannot truncate whole access database and reload. I just have to delete duplicate rows from access db and add new records.
How do I add only new rows to a destination table (when copying a table from another database every night) ?Every night I am copying a number of tables from one database to another.I only want to insert news rows (that are not in the destination table, but are in the source table) to the destination table.I might normally drop the destination table and just copy over the whole table, but in this case rows can be deleted from the source table, but I want to keep these old rows in the destination table (to maintain history). So I only want to add in rows to the destination table that have been added to the source table since last time.I guess I could copy the whole of the source table to a temporary table in the warehouse, then use a T-SQL merge command to compare and just add new rows to the destination table- but suspect that this is not the best way.

It was an interview question, what's the best way to update a table with 10 billion rows.
View 16 Replies View RelatedThe only way to add a new column to an existing mapping that I know is to go to advanced editor and refresh. This however keeps only the default mapping (where the field names match), the rest is wiped out, so need to restore the mapping manually after that. Risky and annoying at the same time. Is there any alternative?
View 3 Replies View RelatedI've a SSIS 2008 parent/child package solution to manage data transfers between two different data sources, so we can copy multiple tables and capture how many rows were transferred and duration for each transfer. This solution was working fine up until last week, when I made some changes to allow the package to perform a source count using standard SQL determined by an expression, or SQL provided from configuration tables, I also changed the package to Truncate or not the destination table, again controlled by configuration settings in a table. The child packages which perform the data flows have not changed!
The day after the controlling package promotion to live, I saw the bizarre behaviour of the Package log stating all rows transferred, but the actual table counts were not what the log stated, see attached file. The package solution works ok on other servers and was ok in DEV, but there were less tables and rows transferred.Re-running the package gave the same errors, but on some of the same tables and some different ones.Â
As it is the child packages doing the transfers and nothing has changed in them. I cannot see how the log would be able to say all rows are transferred and yet not all of the rows are actually moved?
Process output - where you can see counts and log Table transfer controller (as txt not dtsx)
An example of the data transfer child packages (as txt not dtsx)When I set the ExecuteOutOfProcess = True the package worked fine, unfortunately, this is not a good solution as SSIS 2008 does not tidy up the Dtshost.exe processes it starts and I'd be left with a memory issue after a very short time, we transfer hundreds of tables each day. ( I could write a .net script in the controlling package to kill the child processes, but that would still have hundreds of processes running before I could end them, as we have three parallel streams to allow a bit better performance.
In order to update an Oracle table target from a SQL Server table source I need to use a Foreach Loop Container, so I can loop on the rows of the SQL Server table source. This source table has two columns: the old identifier to update and the new identifier to apply. I must use the value of the old identifier to filter the Oracle rows to update, while the new identifier is the new value to assign to the filtered old identifier.
I already know how to use the Foreach Loop Container when it is necessary to loop on an unique column of a table/view (using an object variable, using a Foreach ADO enumerator, etc.), but I need to loop on two columns.
I am trying to insert in table using execute sql task.

I have a flat file with the following columns
SampleID  Rep_Number  Product  Protein  Fat  Solids
In the flat file SampleID and Product are populated in the first row only, rest of the rows only have values for Rep_Number, Protein, Fat, Solids.
SampleID and Product are blank for the rest of the rows. So my task is to fill those blank rows with the first row that has the sampleID and Product and load into the table.

I am using SSIS integration between two database. Both databases are sql server 2008. Â using many integration but getting problem in two only only two integration giving problem, both are executing perfectly and out put also not showing any error.
but destination table not inserted/updated anything.
first issue integration is using data flow task with oledb source and destination.Â
second one is using execute task with for-eachloop container.
I've a dataflow task on For Each Loop container at control flow of SSIS package. This For Each Loop container reads the CSV files from the specified location one by one, and populates a variable with current file name. Note, the tables where I would like to push the data from each CSV file are also having the same names as CSV file names.On the dataflow task, I've Flat File component as a source, this component uses the above variable to read the data of a particular file.
Now, here my question comes, how can I move the data to destination, SQL table, using the same variable name?I've tried to setup the OLE DB destination component dynamically but it executes well only for first time. It does not change the mappings as per the columns of the second CSV file. There're around 50 CSV files, each has different set off columns in it. These files needs to be migrated to SQL tables using the optimum way.
Which is the best way to setup the Dataflow task for this requirement?Also, I cannot use Bulk insert task here as we would like to keep a log of corrupted rows.
I have  two tables like hyd,hyd1 but hyd has data ,now I want to delete all rows from hyd at the same time insert deleted rows into hyd1.

I have a  .xlsx file, in that file I get data from the 3rd row. Using SSIS I am converting .xlsx file into .csv file. I am able to convert it but in the .csv file the data are populating from the first row itself. I want to get data in 3rd row it self.

I have a lot of different data flows that need "Derived Column". There are maybe only 5 different such "Derived Column" but they appear many times. Is there a way to eliminate all that double work?

View 2 Replies View RelatedI am new to SSIS and C#. In SQL Server 2008 I am importing data from a .csv file. Now I have the columns dynamic. They can be around 22 columns (some times more or less). I created a staging table with 25 columns and import data into it. In essence each flat file that I import has different number of columns. They are all properly formatted only. My task is to import all the rows from a .csv flat file including the headers. I want to put this in a job so I can import multiple files into the table daily.
So inside a for each loop I have a data flow task within which I have a script component.

I have an Integration services application that retrieves big strings (over 32k) from an ODBC data source and stores them in a SQL server 2005 database as ntext.
Somehow the strings are truncated to 32K. The app only copies the data from the ODBC datasource to the (OLEDB) target.
Also, some of the special characters in the input text are not properly translated.
Any ideas?
I have data rows ( 7 rows and hundreds of colums) obtained by using execute sql task and i placed the output in CSV.
