Question About Excel Source - How To Modify Columns??
Aug 22, 2007
Hi,
I have a package that uses an Excel file source. There appears to be no place to modify the column data types as you can with a flat file manager. As such, the source columns do not match the columns in the database.
I believe I must be overlooking something here.
Can someone please tell me how I can modify the Excel column datatypes?
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.
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?
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
We have found that using the SSIS "Import and Export Wizard" using the "Microsoft Excel" data source that there appears to be a maximum column length of 255 characters for any row.
Even when defining the destination table columns as nvarchar(4000), the wizard fails with the errors shown below.
We have found no workaround except manually changing the imput data. There doesn't appear to be any "Advanced" options for the Excel importer as there are for the flat-text importer. So, no question here, just posting the bug so that *next* time someone searches the web for an answer, this post comes up

edit: After searching further this is documented under "Excel Source" in BOL which provides a registry-based workaround. I guess the issue is that the wizard considers truncation to be a 'fail' case and there's no easy way to override this behaviour, specify the column types nor determine which line is in error)
Truncated text. When the driver determines that an Excel column contains text data, the driver selects the data type (string or memo) based on the longest value that it samples. If the driver does not discover any values longer than 255 characters in the rows that it samples, it treats the column as a 255-character string column instead of a memo column. Therefore, values longer than 255 characters may be truncated. To import data from a memo column without truncation, you must make sure that the memo column in at least one of the sampled rows contains a value longer than 255 characters, or you must increase the number of rows sampled by the driver to include such a row. You can increase the number of rows sampled by increasing the value of TypeGuessRows under the HKEY_LOCAL_MACHINESOFTWAREMicrosoftJet4.0EnginesExcel registry key. )
Hi all, Thanks in advance to any contributions to my question.Im running SQLServer 2000 in a Win 2000 Server env.Background:==========The database has many views that range from simple to complex joins ontables.The selection criteria is fixed eg. 'Where TaskTypeIdent = 2204 andOutcomeId = 123 or 2322 or 1222 andCicType = 87878 ... etc etcRequirement:===========Now what I would like to do is be able to change the 'where =' valuepart ie. 2204, dynamically if and when required, and it will berequired.In other words there won't be a DBA handy to do this when it changeshence I would like to write a front end UI to allow the user to easilymanage this.There are upwards of 200 views like this.Question:========Where in the system metadata can I access (if possible) the source ofthe View such that I can update it with the new values. eg. 'WhereTaskTypeIdent = 7627 and OutcomeId = 2322 or 94847 or 989 and CicType =1111 ... etc etcMany thanksPaul*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!
Hi, I have a table with 4 columns let us say A,B,C,D. column D is computed column with formula A + '-' + B Now, i want to add one more condition to the formula which looks like "A + '-' + B + '-' + C".
Please let me know how to do this using T-SQL as i cannot open the table in design mode in production server.
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.
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.
I am creating an SSIS package witha a Dataflow task, which reads from an Excel source and then uses script component to dumpt the data to multiple tables in Sql Server database
I need to some how make my Excel source dynamic, that is my excel template which i would be using to map the excel columns to script component's input columns would be dynamic..
In other words, I should be able to define the Excel Source, Column Mapping Information, Precedence constraint to the Script component dynamically

I am trying to create a program that transfers tables to flat files. At this point in time, I have suceeded in created one that creates delimited files.
However, I am now trying to create fixed-width files as you can do with the SSIS designer, but programatically.
Is there a way to programatically determine the width of a column from the source table? I can not seem to find any kind of function or member that stores this information or allows me to retrieve it.
I know what I need to change in order to set a width for a column, but I just don't know how to find the width without just asking the user to provide one.
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.
I have a problem and i wish i can get the answers or advices to solve it.
i have like 20 excel files and in each file there is 1 sheet (Planning) . What i need to do is to loop on the on the 20 files (actually this is the easy part and i already done it) the hard part is while looping i need to open each excel file and loop on the 256 columns in it and extract the data from it to a SQL server Database.
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.
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.
Dear Friends, I need to import data from several excel files. How can I configure excel source object to dinamically import each file? The name of the file will be in a parameter of ssis package and this name change frequently, and ach time the filename change I dont want to change the configuration on the excel source? What you sugest? Shoul I use a script component as source?! Regards!
Hi everyone! I am trying to import data into my sqlserver 2005 database from an Excel 2000 file. The database is empty. I am using the worksheets from the file to create the tables and copy the rows. I am getting follwing errors: - Pre-execute (Error)

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
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.
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?
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. Shiko
Dear Friends, I currently have my excel source dynamic for the connectionstring. Using a global variable with the filename and using the expressions of this control to dynamically have the connecttionstring. My problem is that i need tto read always the first workseet and the name changes frequently and generates an erro in SSIS. how can I set the excel source to goes only for the first sheet independently of the worksheet name?! Regards!!
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 John 30 NULL
I need to create an Bulk upload utility using ASP.Net and SQL Server. Below is the process for the uploads -
Excel Template wherein user will enter the details. A Tab-delimited output file will be generated using the VBA. There are 2 tables - one is Temp Table which is replica of the the final table and second is the final table Using File.OpenText(filePath).ReadLine() - All the Rows from the tab delimited data file will be inserted into DataTable.
using SQLBulkCopy the tab-delimited data file data will be inserted into the Temp Table.
Data will be validated based on the data inserted in the temp table. If the data as errors then the temp table will be cleared else the data will be inserted from the temp table to the final table.
My Issue is that in both the tables there is a column (Name : PeopleKey (Int PrimaryKey)). If the user enters Alphabetic value then the Bulk Utility is failing. Below are the two options in my mind -
1. I can change the DataType in Temp table from int to VARCHAR. So, the data can be inserted at first and then I can validate and get the data corrected. But i am not sure whether it is the right way to fix issue as the source and target tables columns are different.
2. When the data in inserted into the Datatable by following Step 3. So, once the data in inserted into DataTable then i can validate there. Thus the source and target tables Datatype will be same.
