Bulk insert into SQL Server from CSV file by skipping first row

Bulk insert into SQL Server from CSV how to skip first row in bulk insert how to skip n rows in bulk insert

Bulk insert is used to Import a data file into a database table or view in a user-specified format. It's not daily using kind of code, so it's very common question on most of the site like. How to import CSV file into a table? How to insert records from a CSV file to a table, delimited by comma? How to load CSV file to SQL Server database? We will discuss here the same but with more detail, so let's start

Suppose we have a CSV file of car detail, which we want to import into our CarDetail table

2008,Acura,MDX,4dr SUV 4WD,70257
2010,Audi,A5,2dr Cabriolet,10150
2008,Audi,A8,L 4dr Sedan,900
2010,BMW,3-Series,4dr Sedan,2700
2010,BMW,X5-Series,4dr SUV,1700 

First of all we need a table CarDetail, so let's create it.

 Create Table CarDetail
(
  Year int,
  Make varchar(50),
  Model varchar(50),
  Body varchar(50),
  Odometer int
)

Before writing the code to insert record, one thing we need to remember, our CSV file should be on the server if we are using the drive name, as I am going to use. Now run the following script to insert records into our car detail table.

BULK INSERT CarDetail
FROM 'C:\CarDetailCSV.txt'
WITH
(
   FIELDTERMINATOR = ',',
   ROWTERMINATOR = '\n'
)
GO

If there would be any error in any line that record will not be inserted but the rest will. Now you can check your car detail table

Select * From CarDetail

Now let's say your CSV file have header row as well and you don't want to insert the header, but you want to insert record from second row by skipping first row, see this file

Year,Make,Model,Body,Odometer
2008,Acura,MDX,4dr SUV 4WD,70257
2010,Audi,A5,2dr Cabriolet,10150
2008,Audi,A8,L 4dr Sedan,900
2010,BMW,3-Series,4dr Sedan,2700
2010,BMW,X5-Series,4dr SUV,1700

So how to skip first row, it's easy use FIRSTROW = n, where n is the row number from where you want to insert record, nth row will be treated as first row.

BULK INSERT CarDetail
FROM 'C:\CarDetailCSV.txt'
WITH
(
   FIRSTROW = 2,
   FIELDTERMINATOR = ',',
   ROWTERMINATOR = '\n'
)
GO

Suppose our CSV file is huge, which will take time to insert all records so I want to test with inserting from 5th to 50th record only, is that possibe? Yes, it is, in that case we need to use FIRSTROW =5 and LASTROW = 50 like this

BULK INSERT CarDetail
FROM 'C:\CarDetailCSV.txt'
WITH
(
   FIRSTROW = 5,
   LASTROW = 50,
   FIELDTERMINATOR = ',',
   ROWTERMINATOR = '\n'
)
GO
