When i am trying to export data from excel to sql table using ssis,the all rows are inserted . But,when i am inserting a data of length greater than 255 to excel it's giving truncation error. In output column i altered it to 500. in External column input i can't alter it. In my excel sheet there is 2808 rows..but when this error is generating its only inserting 1632 rows and whole other rows are getting truncated....
If any one knows about this,please help me..I am really stuck on this....
Thanks..
Try sorting your data by length eg longest first.
Excel import/export is very buggy in SSIS.
Sometimes the only option is to write VBA script and run it from excel itself

I need help creating table in DB through Excel.
User has table in excel sheet, which has not exact count of columns. User can add or reduce columns and of course add or reduce rows too.
I need a script for example for ODBC Microsoft Query which choose all table range in excel sheet and create table with this data in DB (MySQL).
It has to work on a one click not manually.
Thank you
This is solution for me. It's not exactly what I wanted, but it's enough for me now. After some modifications, it works on MySQL.

I'm trying to import data from a MySQL database into an Excel workbook via an ODBC Data Source.
I have a big problem with the time(3) fields from MySQL. Excel imports the content not as expected. As first try, Excel cut the milliseconds off. Then I edited the query at the specific fields to:
DATE_FORMAT(jobstat_0.PreProcessingQueued,'%T,%f')
This puts something like:
00:00:00,156000
That's what I expected, but I can not change the format in Excel.
Excel interprets the content as text, and if I change to the specific time format, Excel does not care...
I need to correct that to get Pivot Tables working. As a result there are Divide By Zero errors in my Pivot Table.
May be someone had something like that?
I have a simple DataFlow with two objects the source which is a mdb file and the destination which is an MSSQL database.
The idea is to migrate the data from one to another.
The problem is that the data is extracted from an Access query, and one column has ~1000 characters, and in SSIS in advanced properties the external column has the default 255 length so when i execute the task it tries to truncate it. To disable the throw error on truncate is not an option, and modifying the Length of the external column cannot be done, it throws and error regarding the metadata.
First of all can anyone explain WHY?
Second of all i need a resolution and i need it fast because it's kinda driving me crazy.
This kind of problem occours, because the ssis task "guesses" the length of the column by inspecting the first 100(afaik) rows. So if all rows from 1 to 100 have a length of 10 and the row 101 has the legnth of 11, the task will fail, because the length was "guessed" to 10.
Modifying throws an error, because you have validateExternalMetadata set to true. To solve this problem, go to advanced options of your import task (access) and set the value to false.
This means, the task will accept modified values you entered without checking it.
Did you try to SSIS Import and Export Wizard to import the data, from within the BI development environment? That is the easiest way with MsAccess as this not only imports the data but also saves the package. If you get an error during the import ( using the wizard), please post it, as this helps in further investigation. Also, as #stb suggested, try having the first record over 1000 characters.
Access supports queries which are the equivalent to views in MSSQL.
The column size is defined not by looking at a few results but by the default column length of the column data type.
I created another table with the desired data types and before the data flow i've put in the package 2 sql scripts: one to delete all the data in the table and one to execute the query against the table, as to treat it as a temporary table.
Then the actual data flow is executed against this pseudo-temporary table.
This solved my problem.
SQL 2008 : Using SQL SSIS Package, I am exporting Excel Sheet to Text File and then Exporting to SQL Database. I decided to follow two steps of Export process as because of datatype mismatch between SQL Database and some of Excel Columns. When there is a mismatch in the Datatype, SSIS Package stops the Export Process but results as SSIS Package ran successfully.
To avoid partial import of Excel sheet, i decided to follow two steps of export. When different datatype of Excel Sheet goes to Text File, it reflect as String. When i am exporting back from Text file to SQL Database,it goes as STRING and again failing to export due to datatype mismatch.
Major Issue : If there is a mismatch in the Excel Sheet at nth row, Export stops at the nth row. Still, we get the output as Package Successful.
How to fix the datatype mismatch of Excel Data Export to SQL Database ?
You could approach it slightly differently as follows: read the excel spreadsheet in directly to one or more staging table(s) but force all columns to be VARCHAR/NVARCHAR columns. This will then enable you to read all rows into SQL without errors. Then create a second DFT to read from the staging table(s) into your correctly defined table(s)(correctly defined in terms of field type/size). You can build error logging into the second DFT to pump erroneous rows into an error table for later attention.
What is the correct way of importing data from Excel 2007 file to SQL Server database 2008? The data from excel file should be transferred successfully even if the data in Excel file is changed / replaced with different data except the column name at first row.
Excel is very finicky about how you remove rows from it. Your best bet is to select all rows below the column headers and right click and delete. If you simply clear contents and then don't paste in as many rows, it looks to SSIS like you have rows with nulls in them which sometimes causes the types of errors you are seeing.
