Upload CSV file to SQL server

Question

What is the best way to upload a large csv data file into SQL server using C# ? The file contains about 30,000 rows and 25 columns.

Answer 1

You can also use Bulk Insert

Public Shared Function bulkQuery()

        Dim query As StringBuilder = New StringBuilder

        query.Append("USE Import_DB BULK INSERT dbo.[Insert_Table] FROM")
        query.Append(" 'C:\Insert_Table.csv' ")
        query.Append("With (FIELDTERMINATOR = ',', ROWTERMINATOR = '\n')")

        Return query.ToString

    End Function

Be carfully here though since tablename and csv name has to be identical as well as the column count in the csv has to be the same as in the pre-defined table.
