Excel Source Dt_ntext Problems
Jun 20, 2007
Hi:
I import data from multiple excel files into SQL DB. I have trouble with fields that could contain >255 chars.
If I have the col type = DT_Ntext in my Data Flow, the package fails for files that do not have any values >255 chars.
If I have the external coltype=dt_wstr and the output coltype=dt_wstr(4000) the package fails if the file contains any value >255 chars.(Implicit conversion does not occur, as expected).
I worked around by adding a dummy first row with >255 chars.
Is there a way to use a cast function to solve this prob? I tried using Select dt_ntext(fieldname) from Sheet1$, but that does not work.
Is there some clean way to get around this problem?
TIA

I am using a Excel Source to get the data from an excel file to sql server 2005 table. A couple columns are coming in a double precision float, but some values have characters in them, but those values are coming out as null, even though I changed the datatype from float to unicode string. Any inputs on resolving this will be much appreciated.
Thanks,
Manisha

I am trying to get the contents of the Excel Files dynamically and dumping into the SQL Database using SSIS. Through WMI Event Watcher, I could find when one or more Excel files dumped in a particular folder and using ForEach Loop Container I was able to take all the filenames and pass it through Variables. But at the same time in the Data Flow, I have to pass each Sheet of an Excel File to the Excel Source control and export the data to my SQL Database using OLEDB Destination.
For that I need to get the names of each sheets in an Excel File and pass it to the Excel Source Control through variables. But when I give Data Access Mode as "Table name or view name variable" and provide the variable name in that, then it is giving an error message as "A destination table name has not been provided".
And at the same time, Since I was not able to provide an static Filename (as I am passing through Variables), when I tried to map the columns in the OleDB Destination, it is not allowing me to map the columns.
So all these things I should do at Run-time using Variables in SSIS. I don't want to hard-code any filenames or Sheet names. If any one of you have a solution, please share with me.
Thanks & Regards,

Hello,
I have a problem with retreving a excel data through excel source component.
I have source component as Excel Source which will connect to my .xls sheet.
To retrieve the values from the sheet i am using a query as,
"SELECT F14,F3 FROM [Charac Defn & Assgnment$]"
The column F14 is not formatted so that the format of the cell is "General" I have a different type of values in the F14 column such as "PE","PES",15,20,20.00,8888.9999 etc..
While i click on preview button of Excel source it shows only the text values and not the int or decimal values, its returning NULL for those cells. I tried to use convert function, its throwing an error as
TITLE: Microsoft Visual Studio
------------------------------
There was an error displaying the preview.
------------------------------
ADDITIONAL INFORMATION:
Undefined function 'Convert' in expression. (Microsoft JET Database Engine)
Is there any other function to change the format of the cell or i need to some thing else
Please help me how to solve this issue.

While importing data from Excel source , some column is getting null value even though excel column has value.To Resolve the issue we tried with
HKEY_LOCAL_MACHINESOFTWAREWow6432NodeMicrosoftOffice14.0Access Connectivity EngineEnginesExcel
1.Change the Value of the Row TypeGuessRows from 8 (Default value) to 0 and ImportMixedType = text
• xls
HKEY_LOCAL_MACHINESOFTWAREMicrosoftJet4.0EnginesExcel
1.Change the Value of the Row TypeGuessRows from 8 (Default value) to 0 and ImportMixedType = text
the connection string of the excel
UPPER(REVERSE(SUBSTRING( REVERSE(@[User::VarInputExcelFile]), 1, 5) ) ) == ".XLSX" ? "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + @[User::VarInputExcelFile] + ";Extended Properties="Excel 12.0;HDR=Yes;IMEX=1";":"Provider=Microsoft.Jet.OLEDB.4.0;Data
Source=" + @[User::VarInputExcelFile] + ";Extended Properties="EXCEL 8.0;HDR=Yes;IMEX=1";"
by doing the above setting also , the column is coming as null from excel source even though there is data in excel.

Hi All,
I am importing data from an oracle db and one of the columns is a nclob. I would like to truncate the value if it is more than a certain length. I want to use a derived column transformation. I cannot use the len and substring functions because it is not a string. I could convert it to a unicode string and use those functions, but I am afraid there is a size limitation (4000 characters) on it. Is there smth I am missing? Can anybody please suggest any ideas?
Thanks a lot.

Hi again!
I have another problem, this time with a flatfile source component. The file is pretty simple organized and in fact everything works as expected.
The file itself comes from an FTP server, so it is not available at designtime. For setting up the flatfile source i downloaded it, but afterwards i delete it, set 'dalayvalidation' to true and try to execute.
FTP download works fine, the file is there but then i get the errormessage:
Copier ErrorCodes [586]: The data type for "output column "Flat File Source Error Output Column" (610)" is DT_NTEXT, which is not supported with ANSI files. Use DT_TEXT instead and convert the data to DT_NTEXT using the data conversion component.
When i try to set the datatype of the Error Output Column (610) to DT_NEXT i only get an errormessage telling me that this would not be a valid value for this property.
The only chance i have to get it working again is to completely delete the flatfile-source, readd and setup it again, then everything works... but only until i remove the files and try to download them via FTP. It's strange :-( and annoying.
Anyone any idea?
kind regards,
Wolfgang

The IC column referenced in the script below is DT_NTEXT, so when I run it the output value column gets "Microsoft.SqlServer.DTS.Pipeline.BlobColumn" instead of the individual codes (separated by "*"). Also, there is only 1 output row per input row, instead of 1 output row per code.
I found some references to the GetBobData() method, but replacing Row.IC.ToString() with Row.IC.GetBlobData(0, CInt(Row.IC.Length)).ToString() puts "System.Byte[]" in the value output column. There is still only output row per input row.
So how do I convert the IC column to a String that can be Split()?Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)
Dim seq As Integer = 0
For Each code As String In Row.IC.ToString().Split("*"c)
'Add a row to the output buffer:
Output0Buffer.AddRow()
'Preserve columns from the input buffer:
Output0Buffer.itemid = Row.itemid
Output0Buffer.attributeid = Row.attributeid
'Output0Buffer.IC = Row.IC
'Add output columns:
Output0Buffer.seq = seq
Output0Buffer.value = code
seq += 1
Next
End Sub

I have a script component that I have written and works as long as the Output columns on the script are string types. When I change the output column type to text (since the size could be essentially unlimited) it gives an error in the script component that the property is read only.
Here is the code line that fails with Property Payments is read only.
Output0Buffer.Payments = fieldValues(i)
If I change the column payments to DT_Wstr it works without issue, but I want to use text incase the value is large.
Here is the error if you try to run the actual script even though I know it has an error.

I have the Excel Connection Manager and Source to read the contents from an Excel file. For some reason couple of numeric fields from the Excel worksheet are brought over as nulls even though they have a value of 300 and 150. I am not sure why this is happening. I looked into the format of the fields and they are set to General in Excel, I tried setting them to numeric and that did not help.
All the other content from the excel file is coming thru except for the 2 numeric fields.
I tried to bring the contents from the excel source to a text file in csv format and for some reason the 2 numeric fields came out as blank.
Any inputs on getting this addressed will be much appreciated.
Thanks,
Manisha

The documentation on the fuzzy lookup transform mentions that only columns of type DT_WSTR and DT_STR can be used in fuzzy matching. I interpreted this as meaning that you could not create a mapping between an input column of type DT_NTEXT and a column from the reference table. I assumed that you could still have a DT_NTEXT column as part of the input and mark this as a pass through column so that it's value could be inserted in the destination, together with the result of the lookup operation. Apparently this is not the case. Validation fails with the following message: 'The data type of column 'fieldname' is not supported.' First, I'd like to confirm that this is really the case and that I have not misinterpreted this limitation.
Finally, given the following situation
- A data source with input columns
Field_A DT_STR
Field_B DT_NTEXT
- A fuzzy lookup is used to match Field_A to a row in the reference table and obtain Field_C.
- Finally, Field_B and Field_C must be inserted into the destination.
Can anyone suggest how this could be achieved?

I'm trying to write a DTS package that reads data from an excel spreadsheet. I'm having a problem getting all the data from the spreadsheet, seems that OLE DB is "too" smart. There is one column that has either numeric values or text values in its row cells. When I browse the spreadsheet in DTS (transform properties, browse button) I only see the text values. OLE DB has placed nulls or blanks into the cells with the numeric values. If I edit the spreadsheet to change the column header to contain a number, then the browse window shows only the numeric values and blanks out the text values. Any suggestion on how to get OLE DB/DTS to treat the numeric values as text? In the spreadsheet, I've tried changing the cell formats to text and to general. This had no effect.

Hi,
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.
xlsQuery
CREATE TABLE `Sheet1` ( `FiscalYear` Short, `FiscalPeriod` Byte, `STORE #` Short, `Total Markups` Decimal(15,2), `Less Markdown SubTotal` Decimal(15,2), `Total Markup` Decimal(15,2) ) GO
sqlQuery
Exec Report.MyReport 1
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.
Please Help
Thanks

Hi:
I use a SSIS package to loop thro a folder and load data from multiple excel files to a SQL2005 table. Works fine except when an excel has a missing col.
Col names in xls are always a subset of col names in the table. The missing cols are random, else I would just have made another package:-)
Once a missing column is found, I get runtime and design time errors, and metadata problems. How can a get SSIS to ignore missing columns?
TIA

Hi,
I have an Excel spreasheet - the first column is text, the second numbers, the third a mix of the two. If I point An Excel Source at this in my data flow, it will import the first two columns without problem, but not the third: all cells containing text are being imported as nulls, but those containing numbers are imported just fine.
Even if the numbers are stored as text, they are converted into numbers at import and genuine text is still discarded. It's treated as if the entire column is numeric if there's just one numeric value in it.
I can get around this by creating a .csv or .txt file from the excel file, but that will add an extra layer of admin to this process and I'm tryuing to make it as seamless as possible

Hello,
I'm a SSIS beginner.
I need to create users in my database from an Excel file source.
I have an Excel source with user name and email.
I would like to use SSIS to go though the Excel file and execute a store procedure (create_user @name @email @password OUTPUT) for each row and then create an output file with the new created password (a random password is created for each user and the stored procedure has an output @password)
I tried to "plug" an "Excel source" to an "Execute SQL task" which execute my store procedure.
But as a SSIS beginner I don't really understand how to pass the parameters (name and email in the Excel file) to my stored procedure. There is the concept of variable a for each loop thing... but i dont really know how to start.
I would be greatfull if someone could tell me a solution to my problem.
Cheers

Guys,
I have some data in an excel sheet. Some of the columns have a few NULL values for certain amount of rows till is gets data. What makes it so weird is that when priviewing this in the wizard, the whole column is filled with NULL values when the number of leading NULLs is quite large. When NULLs are quite a few, the column works fine!! Can anyone explains this? We tried some manual work to cut some of the rows from below and put them at the start and it worked! It's so strange though this behavior.

I've a package that has a excel source. But i'm having a strange problem with it. One of the columns in the source file have a lot of null values but not all of them. But when i run the package a put a data viewer right after the source and i can see that it's showing that the few fields that should have values are also null. I've tried a lot of things but they didn't work. I need some help and fast if possible.
Example: Source file.xls
Name Grade OtherGrade
John 30 30.23
In the DataViewer
Name Grade OtherGrade

Hi all,
I've had little success gooling/searching for this (so far).
Given a simple spreadsheet:
StoreNumber StoreName
1
UPDStoreName_1
2
UPDStoreName_2
3
UPDStoreName_3
4
NEWStoreName_4
I want to have an SSIS package that will update a table: mystores (storenumber int, storename nvarchar(255))
StoreNumber StoreName
1
StoreName_1
2
StoreName_2
3
StoreName_3
5 StoreName_5
.. what I need to do is insert the new, update the existing and leave the remaining unchanged. i.e. :
StoreNumber StoreName
1
UPDStoreName_1
2
UPDStoreName_2
3
UPDStoreName_3
4
NEWStoreName_4
5 StoreName_5
(the UPD and NEW are added to simplify the example).
Now the default action of an excel source into an ole db destination is
an insert into the table - so PK constraints causes failures.
Now, given that the table is referred to by other table, and is in a
24x7 website, how do I change the SSIS package such that, on a
row-by-row basis, anUpSert (update or insert) is performed?
The only idea I have so far is:
create temp table
insert excel data into temp table
iterate through the table, using if exists ... update else insert logic <-- this to be done in a SP
Isn't there a better way?

Hi
I have an excel source which is a 41 column sheet. The excel filepath is stored in a table and captured into a variable. The excel source import is contained within a foreach loop and will loop through each file and continue until all the excel files are processed. It works fine until it gets to the last file. The import then fails with the following error:
The column "F42" needs to be added to the external metadata column collection.
The column "F43" needs to be added to the external metadata column collection.
The column "F44" needs to be added to the external metadata column collection.
The column "F45" needs to be added to the external metadata column collection.
The column "F46" needs to be added to the external metadata column collection.
The column "F47" needs to be added to the external metadata column collection.
Now when i open the excel sheet and hit CTRL+END the cursor goes to a column 6 to the right of the last column with data in it, effectively column 47 where column 41 is the end of my data.
I guess that the jet engine is trying to import these additional columns but because i am not expecting them there is no destination set up for them in the OLEDB destination and susequently the metadata needs to be added. I do not want to do this as these are excel files originating from the client and i cannot control how many additional columns they are going to "add".
Does anyone have any ideas as to how i can solve this? Is there a way of identifying the last column with data and only importing those columns?
Thanks in advance for any help or experience of this issue

Hi,
We have a excel 2007 file with a Pivot Table in it. We would like to use the same as data source (But all the source fields as it comes for Pivot). The key issue is that the data to the pivot is from a connection and points to DB - but there is no access to DB. So the Excel is static to us with a PIVOT in it.
Is there a way to get all the data that is avaialble as a source for pivot.
Ex. The select query has co1,co2....co 11 from xxxxx
whereas the PIVot HAS ONLY cO1, CO2 AS ROW, CO3,CO4 AS COL, CO5 AS VALUE AND CO6,CO7 AS FILTER AND OTHERS MISSED OUT IN PIVOT.
THe SSIS as such provide Excel 2007 access to Access OLE DB driver with Excel 12 setting in advanced tab. But not sure whether we can give the range (or) a way around ot get all the data as available in excel regardless of what is used only in the pivot.

Hi,
I have an Excel source, which I have hooked up to a Data Conversion task. I have defined "Output Aliases" for all my columns in the Data Conversion task.
However, when I try to map the columns from the Data Conversion task to the table columns, there is a list of column names, which do not correspond to the names I defined as "Output Aliases."
For example, one of the Output Aliases is "col1." However, when I go to map it, the column name is not "col1" but "My Excel file.col1".
Why is this happening? I have not had this problem before.
Thanks
