Is there any best way to upload 14 million records into SQL Server database, without splitting the file.
Thanks in advance.

I have tried with import export wizard tool, but the database freezes.
I am expecting an alternate source to upload the 14 million records to SQL Server.

sql-server

The fastest way is using the Bulk Insert. You can insert the data into table or Common table expression CTE or table variable or temp table then I'd remove the duplicate rows across the distinct and Joins command from t-sql.

BULK INSERT TableName
FROM 'C:\SomeDirectory\my table.csv'
WITH
(
    FIELDTERMINATOR = '\t',
    ROWTERMINATOR = '\n'
)
GO

And here is the full parameter description.
