Importing from Excel or a CSV file

Question

I need to import data to a sql table finding a row by column A and putting column B and C into the row into specific data columns.

My excel/CSV file is similar to:

Code,Unit,Price
1234,Pack10,1.20
4567,Each,3.40

My table is similar to

ItemID Code Name ItemPrice Unit Supplier LastCost SellBy QtyStock Inactive

I need to update the table from the lines in the spreadsheet finding the code row and replacing the Unit and the ItemPrice columns.

I have tried using the standard import data but cannot see how to find the code and then insert the required fields.

Any help or point me to where I can find an answer will be most appreciated.

Answer 1

Breakup the problem into two smaller steps... First, do just the standard import data, and place the contents of your excel file into a SQL table. After you've imported the data, perform just a standard SQL update statement to join together your imported table and your existing table to update the existing table.

UPDATE e
SET
    Unit = i.Unit,
    ItemPrice = i.Price
FROM
    ExistingTable e JOIN
    ImportedTable i ON i.Code = e.Code

To make it in a single step you can use OPENROWSET as follows:

UPDATE A
   SET [ItemPrice] = B.Price,
       [Unit] = b.Unit
FROM   [SO].[dbo].[PricesTbl] A INNER JOIN
       OPENROWSET('Microsoft.Jet.OLEDB.4.0',
       'Excel 8.0;Database=C:\Prices.xls', 'SELECT * FROM [Sheet1$]') B ON A.CODE=B.CODE
