在SQL Server中导入CSV文件

Question

I want to import csv data in sql server. I searched about and found answers about BULK INSERT ... FROM.

The problem I have is :

• I want to select just one column of my results
• The table already exists with bad datas and I just want to update these fields

The CSV I had contains towns and its parameters (correct datas)

Town,Id,ZipCode,...
T1,1,12000
T2,2,12100
T3,3,12200

And the table in SQL Server 'town' contains for example T1,1,30456 T2,2,36327 T3,3,85621

I just want to get ZipCode in CSV and update the ZipCode in the table in function the ID. Does it exist an easy way to do it ?

Answer 1

I normally prefer bcp over bulk insert because with that you can easily import the files over network and there's less issues with access rights. Otherwise I would just load the data into tempdb and update the original table from there.
