The valid range of values for the TypeGuessRows key is 0 to 16. However, if the value is 0, the number of source rows scanned is 16384. Keep in mind that a value of zero may cause a small performance hit if the source file is very large.
Steps to Reproduce Problem
- Open a new Microsoft Excel workbook and create a sheet with three columns and 11 rows and include the first row with column names.
- Insert data into the cells so that the first 8 rows have data less than 255 characters in length.
- Insert data that is greater than 255 characters in length into the 10th and 11th rows. Save this sheet as ExcelSource.xls.
- Open the SQL Server Enterprise Manager and expand the Server name. Right-click Data Transformation Services, and then click Import Data.
- For the Source, select the Excel 97-2000 provider and provide the name for the Excel sheet that you saved earlier (ExcelSource.xls).
- For the destination select Microsoft OLEDB provider for SQL, and then select the destination database.
- Click Copy Tables and Views from the source DB, and then click Next.
- In the Select Source Tables dialog box, select Sheet1$, click Next, and then run the package immediately. The package execution fails with the error message shown in the "Symptoms" section.
- Drop the table Sheet1$ from the destination database by using the command Drop Table Sheet1$.
- Follow the resolution in the "Workaround" section and make the change to the registry key for TypeGuessRows.
- Now, repeat steps 4 through 8. This time the package execution is successful.
