Does anybody else have this same problem, when you import data from Excel file to MSSQL Server 2005, if some column contains mostly numeric data, but even if you set the column type to varchar, the wizard fails to import those fields that fail to parse as numbers?
回答1:
Try this (Note: These instructions are based on Excel 2007)...
The following steps should force Excel to treat the column as text:
Open your spreadsheet with Excel.
Select the whole column that contains your "mostly numeric data" by clicking on the column header.
Click on the Data tab on the ribbon menu.
Select Text to Columns. This will bring up the Convert Text to Columns Wizard.
-On Step 1: Click Next
-On Step 2: Click Next
-On Step 3: Select Text and click Finish
Save your Excel sheet.
Retry the import using the SQL Server 2005 Import Data Wizard.

You need to edit the connection string that SSIS uses. Add this to the end of the string "IMEX=1;" (No quotes) That tells SSIS/jet to not try and figure out what the data types are. Just import them.

You might try tweaking Jet settings for importing Excel data. You can force the Jet engine to sample the entire sheet when trying to determine the column type during a given import. Change the following registry key (after making a backup first) and see if that doesn't do it:
HKLM\Software\Microsoft\Jet\4.0\Engines\Excel
Or on x64
HKLM\Software\Wow6432Node\Microsoft\Jet\4.0\Engines\Excel
Set the value TypeGuessRows equal to zero. This will force Jet to sample all rows to determine the column type.

Create a new column that is an apostophe + the contents of the column you want to import. This will force it to be a string
="'"&E2

Adding IMEX=1 BEFORE the HDR setting worked for me.

This is the best solution:
Click File on the ribbon menu, and then click on Options.
Click Advanced, and then under When calculating this workbook, select the Set precision as displayed check box, and then click OK.
Click OK.
In the worksheet, select the cells that you want to format.
On the Home tab, click the Dialog Box Launcher Button image next to Number.
In the Category box, click Number.
In the Decimal places box, enter the number of decimal places that you want to display.
