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
