Problems importing data from plain text file

Hi,

I have this plain text file with about 5000 lines.
Each line may have 4 or 5 fields, all delimited with a tab.

I've made a table named t_zip_codes with 5 fields.

When i run (in postgres command line) the command

COPY t_zip_code FROM zip_codes.txt;

it aborts as soon as it reaches a line with only 4 fields in the text
file, because the table t_zip_codes have 5 fields.

How can i solve this annoyance ?
All my fields are character varying.

Any help would be appreciated.

Warm regards,
Mário Gamito

by adding the 5th field where missing ? with something like:
perl -pi.bak -e's/$/\t/ if tr/\t/\t/<4' zip_codes.txt

should be easy with sed, as well
(or just with your favorite editor)

I want to be able to import an Excel spreadsheet into Access 2K using the macro command Transferspreadsheet.

(The records in "error" are actually empty fields.) This is a regular event and I do not want to...

I can import a csv file with no problem. I can also add columns to the datagrid upon import. I want to be able to start importing at the 3rd row. This will pick up the headers necessary for the datagrid. Once I can get to that point I need some way to be able to add new data only to the new columns that were added. Here is some of my code: //Function For Importing Data From CSV File public DataSet ConnectCSV(string filetable)

What do others do if you need to import excel files into SQL Server? My main problems are 1) zipcode formatting issues. If the column is a mix of zip and zip+4, I have problems retrieving all zipcodes. 2) If the last column contains NULL no information is imported. All this with using the Management console using Import data in SQL Server 2005. I am simply trying to import the data into NEW databases.
