To Validate # Of Excel Rows(source) And Sql Server Table(destination) Rows Are Equal
Feb 20, 2008
Hi,
When expoting data from excel to sql server table, using SSIS package, after exporting is done, how would i check source rows are equal to destination rows. If not to throw an error message.
When expoting data from excel to sql server table, using SSIS package, after exporting is done, how would i check source rows are equal to destination rows. If not to throw an error message.
How can we handle transactions in SSIS 1. when some error/something happens during export and the # of rows are not exported fully to destination, how to rollback the transaction in SSIS.
Running this code on my PC via VS 2005 .Net version 2.0.50727 on the server (shown in IIS) Code is in ASP.NET 2.0 and is a VB.NET Console application SSIS 2005
Problem & Info:
I am bringing in an Excel file. I need to first strip out any non-detail rows such as the breaks you see with totals and what not. I should in the end have only detail rows left before I start moving them into my SQL Table. I'm not sure how to first strip this information out in SSIS specfically how down to the right component and how to actually code the component to do this based on my Excel file here: http://www.webfound.net/excelfile.xls
Then, I assume I just use a Flat File Source coponent or something to actually take the columns in the Excel and split into an OLE DB Datasource to shove each column into a corresponding column in my SQL Server Table. I have used a Flat File Source in the past to do so with a comma delimited txt file but never tried with an Excel.
Desired Help:
How to perform
1) stripping out all undesired rows 2) importing each column into sql table
I export one table to Excel using Export Wizard. Second time I have used this creator I have checked option "Delete rows in destination table" because table already exists in Excel file.
During execution I get an error:
"Error 0xc002f210: Preparation SQL Task: Executing the query "DELETE FROM 'MyTable'" failed with following error: " and here is my translation from my language: "Deleting data from linked table is not supported by this version of ISAM"
I have also saved this package to a file and here is the full connection string to my Excel file:
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:Documents and SettingsprzemekPulpitmyfile.xls;Extended Properties="EXCEL 8.0;HDR=YES";
Few days ago I have been using SQL2000 on the same machine and the same export was working properly.
I am exporting table rows (based on a query) into an excel file but I don't want to append to the file. I would like to delete the rows that were previously added and then add the new data. The file has column headings and I would like these to exist all the time.
I know how to export the data but don't know how to delete 'old' data rows from excel.
I have a data task with the following requirements: 1) Run query against database to retrieve rows 2) Add header and footer row to the result set. The footer row must contain a count of the records. 3) Write the rows to a fixed width file if there were any data rows
I have got to the point that I can create the file (using a set of tasks that includes derived columns, sorts, aggregation and merges). However the file is created regardless of whether there were data rows returned. I can't check the row count before proceeding as this isn't set until the data task ends. And if I try to split them into separate data tasks (so that I can access this variable and perform conditional execution) it becomes harder to access the original rows.
Do you have any recommendations on the best way to achieve this? It all seems to be very complex and I'm starting to feel that it would be easier to do this outside of SSIS... Please help me to keep the faith!
For those interested this is a slightly simplified version of what I have so far (all within a single data task):
1.Run dummy sql to create header row 2.Run main SQL to retrieve rows | | | 3.Multicast | | | | | 4.Create footer row by doing sum() in aggregate task | | | | 5.Merge body and footer | | 6. Merge header with body and footer |
I am in a bit of a quandry. I have an Excel spreadsheet source, but I only want certain rows from the spreadsheet, which will be delineated by a header and footer row (Start and End). Here is my script thus far (see below).
My question is, what is the correct way to do this? I guess I am stuck on syntax. i.e.) Do I need to create an OUTPUT BUFFER?
Thanks
==============================
Sample data: blah Start Frank 1234 1234 1234 Sue 2345 2345 2345 End blah blah
==============================
Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)
Static Section As String
'Set sections
If Row.Name = "Start" Then
Section = "Start"
End If
If Row.Name = "End" Then
Section = "End"
End If
If Section = "Start" Then
'GRAB THESE ROWS AND SEND THROUGH THE PIPELINE 'IGNORE ALL OTHER ROWS! 'What syntax goes here? 'Output buffer?
I am trying to ETL from excel source to SQL table. When I created the package my excel had certain number of rows. Later if I add (append) few more rows in the spreadsheet ... the ssis package (also in excel source preview) not reading the newly added rows. Suprisingly it is reading new rows if they are inserted in between existing rows.
The columns in my excel source contain data of different types with the column name being a string and the data in those columns being integers. Is there any way to only extract numeric data , in short I want column names to be omitted. Also the data is distributed unevenly , beggining at various rows in each column.
Hello, I am getting this warning message,when I am trying to load an excel file to a table [Excel Source 1 [12717]] Error: A destination table name has not been provided.
These are the steps I am performing EXCEL source | Data Conversion | OLEDB Destination
In the EXcel Source I have the Data Access Mode as Table Name or View Name variable
Am I missing something.. I tried to give a default value in the variable and then I am getting this warning
Error at Data Flow Task [Excel Source 1 [12717]]: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80040E37. Error at Data Flow Task [Excel Source 1 [12717]]: Opening a rowset for "Order" failed. Check that the object exists in the database.
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.
I am losing data from time to time and can not figure out where the rows are vanishing to. In essence, I have 5 files that I process. The processing occurs on a daily basis by one SQLAgent job that calls 5 individual packages, each doing a different piece of work.
I stage each file to a temp table, then perform some minor transformations, then union the rowsets from each file before landing to another temporary table. A subsequent package performs additional transformations that apply to the entire dataset, before inserting them to their final destination. Along the way, I reject some records based on the business rules applied. Each package in the entire Job is logging(OnError, TaskFailed, Pre and Post execute). Their are no errors being generated. No rows are being rejected to my reject tables either.
Without getting into the specific transforms, etc. being used in this complex process, has anyone seen similar unexplained behaviour? I've not been able to identify any pattern, except that it is usually only 1 or 2 of the record types (specific to a source file), that will ever not be loaded. No patterns around volumes for specific source files. There are some lookups and dedupes, however I've seen the records 'drop off' before reaching these transforms. I have noticed I had my final desination load not using fast load. However sometimes the records disappear before even getting to my final staging table which is inserting using fast load. I am going to turn on logging the pipelinerowssent event. Any other suggestions for troubleshooting/tracking down these disappearing records?
I am copying a simple table from a Sql Server 2005 database to an *.sdf mobile database.
I am brand new to SSIS and I am probably doing something wrong. But after executing the SSIS package all the rows and all the fields are NULL in the destination database. I put a datagrid viewer between the OLE DB Source and the Sql Server compact edition destination and I can see the real data which is obviously not ALL NULL.
Does anyone have a clue as to why it would be doing this?
I have a SSIS package that transfers data from three SQL Server 7 servers to a SQL Server 2005 database. This package has about 30 different tables it copies. The table structures in the source database and destination tables are identical. About 25 different tables load without any issues. I have about 5 tables that load some nights without a problem. On other nights, the data transfers seem to randomly (though usually the most recent records) ignore some of the data. I have logging turned on and receive no errors. It just appears to stop loading data.
I should also mention that I truncate each destination table before begining and each table is loaded from data from each of the 13 source database (I am combining data from 13 regional database for reporting purposes). This is done using a Foreach Loop Container that updates the Server/Region connection string for each region. I am using the OLE DB Source connection to the SQL Server Destination. I have tried as well with the OLE DB Destination with the same result (and no error). I do not do any manipulation to the data on the transfer, but added a "RowCount" transformation between the source and destination and it gives the correct number of rows, but not all the rows get loaded.
You are given say a pricelist of books. And you have to find out all possible sets of books, each of them having total sum of book prices equal to a given number.
set nocount on if object_id('tempdb..#t')>0 drop table #t if object_id('tempdb..#tt')>0 drop table #tt create table #t (n int, price int) insert into #t -- note asc order of book prices select 1, 1 union all select 2, 3 union all select 3, 4 union all select 4, 5 union all select 5, 7 union all select 6, 7 union all select 7, 11 union all select 8, 15 union all select 9, 20 union all select 10, 20 union all select 11, 22 union all select 12, 28 union all select 13, 33 union all select 14, 40 union all select 15, 43 union all select 16, 47 union all select 17, 50 union all select 18, 55 union all select 19, 56 union all select 20, 63 go create table #tt (n int, price int) go declare @rows int, @p int, @sum int set @sum=16 delete from #t where price>@sum set @p=(select sum(price) from #t)
if @p>=@sum begin set @rows=(select max(n) from #t) declare @n int, @s int set @n=@rows+1 set @s=0
while 0=0 begin while @n>1 begin set @n=@n-1 if @s+(select price from #t where n=@n)<=@sum and @s+(select sum(price) from #t where n<=@n)>=@sum begin set @s=@s+(select price from #t where n=@n) insert into #tt select n, price from #t where n=@n if @s=@sum select * from #tt --- outputting end end set @n=(select min(n) from #tt) set @s=@s-(select price from #tt where n=@n) delete from #tt where n=@n if @s=0 and (select sum(price) from #t where n<@n)<@sum break end
end drop table #tt drop table #t
Result for @sum=16 (for e.g. @sum=76 number of different sets = 196): n price ----------- ----------- 8 15 1 1
n price ----------- ----------- 7 11 4 5
n price ----------- ----------- 7 11 3 4 1 1
n price ----------- ----------- 6 7 4 5 3 4
n price ----------- ----------- 6 7 4 5 2 3 1 1
n price ----------- ----------- 5 7 4 5 3 4
n price ----------- ----------- 5 7 4 5 2 3 1 1 EDIT: added one more condition (in blue) into an IF statement. Now it works incredibly fast.
i am dealing with around 14000 rows which need to be put into the sql destination.,But what i see is that the order of the rows in the desination is not the same as in the source,
My OLE DB Source and Excel desintation values all will be assigned during the run time but it does work during design time but as on runtime columns are different. That's why it does not work.
Here is what I want to accomplish, I have table which contains all my report which needs to dumped to excel at the month end.
SQL Task using ADO enumrator read one record(one report), Give that record to For Each contair which Create the Excel file on the fly using one of variable from my table and uses a stored procedure to dump data to excel using Dataflow Task.
Does it mean for 10 reports, I have to create 10 different data flow tasks, or it can be done using one data flow tasks but changing columns on the run time.
I have a SQL script to insert data into a table as below:
INSERT into [SRV1INS2].BB.dbo.Agents2 select * from [SRV2INS14].DD.dbo.Agents
I just want to set a Trigger on Agents2 Table, which could delete all rows in the table , before carry out any Insert operation using above statement.I had below Table Trigger on [SRV1INS2].BB.dbo.Agents2 Table as below: But it did not perform what I intend to do.
USE [BB] GO /****** Object: Trigger Script Date: 24/07/2015 3:41:38 PM ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON
Question pls. I have an MS SQL local package where it exports data from SQL table to Excel file. My question is, how can erase all the records in my excel file before i export the new data from SQL table?
What i want is to delete the rows in the destination file before inserting new records.
I have a table that I'm loading as part of a control flow that in turn is copied to a target table by using a data flow task. I am doing this because a different set of fields may be used from the source entry to create the target entry based on a field in the source table. That same field may indicate that multiple entries need to be created in the target table from one source table entry for which I use a multi-cast transformation.
The problem I'm having is that no matter how many entries there are in the source table, the OLE DB Source during execution only shows 7,532 entries being taken from the source table. If there are less than 7,532 entries in the source table, everything processes fine. More than 7,532 and the data flow task only takes 7,532 and then seems to hang. It also seems as though only one path of the multi-cast transformation is taken when the conditional split directs a source entry down that path.
Seems like a strange problem I know, but any insight anyone could provide is appreciated. Thanks.
that violates the targets referential integrity?I am getting error Msg 2601, Level 14, State 1, Line 1Cannot insert duplicate key row in object XXX with unique index YYY.The statement has been terminated.I would like to know if there is a way to examine or determine what source rows are not conforming to the unique index.I'm fine with dropping and reestablishing the index, and i know its cataloged somewhere because during index creation, the error message does tell you the row details clobbering index creation. Ideally i would like to be able to trap all the failing rows and see what i can do about rehabilitating them or ignoring them or managing them some other way, but id like to know what the server knows when it will not create the index.
I'm getting some strange error handling behaviour when I tried to redirect rows when an error is encountered at the OLE DB Destination. I enabled the fastload option and set the maximum insert commit size to 10,000. My package is trying to insert 1,000,000 rows. When the row containing bad data is encountered, the entire batch is redirected to a separate table with no table constraints. So I have approx 990,000 rows of good data inserted, and approx 10,000 rows in an error table. However, only 2 of the 10,000 rows are actually bad data.
I changed the filter in the data source to reload 5 rows from the 10,000 rows of bad data. The 5 rows include the 2 rows of bad data. The fastload option and max insert commit size at the OLE DB Destination are not changed. When the package completed, 3 rows were inserted to the destination and the 2 bad rows are redirected again. Even though this is the outcome I wanted (only the real bad data is redirected), shouldn't all 5 rows be redirected since they should all be treated as a single batch?
My second question is, is there a way to get the best of both worlds - be able to load lots of data as fast as possible and only redirect the rows that are actually bad?
An SSIS package to transfer data from a DB instance on SQL Server 2005 to SQL Server 2000 is extremely slow. The package uses an OLEDB Source to OLEDB Destination for data transfer which is basically one table from sql server 2005 to sql server 2000. The job takes 5 minutes to transfer about 400 rows at night when there is very little activity on the server. During the day the job almost always times out.
On SQL Server 200 instances the job ran in minutes in the old 2000 package.
Is there an alternative to this. Tranfer Objects task does not work as there is apparently a defect according to Microsoft. Please let me know if there is any other option other than using a Execute 2000 package task or using an ActiveX Script to read records from one source and to insert them into the destination source, which I am not certain how long it might take and how viable will that be?
Dear Friends, Is there any way to display a table data separately like odd rows and even rows?I dont know this is possible or not?If it is possible means how can i achieve it?Please guide me a proper way. Thanks all!
I have a Dataflow task with oledb source that is using SqlCommand to retrieve data and oledb destination to write the source output to a table. I have access to both the source and destination databases.
The problem is the destination component is not writing any rows to the destination table eventhough the Source component is returning rows (I can see them in the Preview and the source database table as well). I'm using "Table/View Name from Variable" for destination.
The Package executes without any errors but there is no output.
I have created a custom script destination using an article found on TechNet. The script executes fine and completes, but with one small problem. The last package execution log entry states "wrote 0 rows". This is a problem because I use this number to verify that all of the database records have been properly transferred.
I have monitored that database when the script is executing and have verified that the data is being transferred property.
Is there some function that I should be calling with each row prcessed in the custom script destination to "tally" the row count? This way the script component will display the proper row count.
Hi. As the title, I am try to figure out how to write script to prevent duplicated rows before loading data from couple csv files to the OLE database table. Another quick question, when I use Data Conversion to convert data from string to datetime or decimal type, it always return error like potential data loss.
