Remove quotation chars from file while bulk inserting data to table – Telegram

This is Users table

CREATE TABLE Users
(
    Id INT PRIMARY KEY IDENTITY(0,1),
    Name NVARCHAR(20) NOT NULL,
    Surname NVARCHAR(25) NOT NULL,
    Email NVARCHAR(30), 
    Facebook NVARCHAR(30),

    CHECK(Email IS NOT NULL OR Facebook IS NOT NULL)
);

This is BULK INSERT

BULK INSERT Users
FROM 'C:UsersSAMIRDownloadsTelegram Desktopusers.txt'
WITH (
      FIELDTERMINATOR = ',',
      ROWTERMINATOR = 'n',
      --FIRSTROW = 0,
      --UTF-8
      CODEPAGE = '65001'
);

So this is Users.txt file data:

`1, N'Alex', N'Mituchin', N'[email protected]', NULL`

When I load data from the file it sets Username to values like N'Alex'. But I want to have the data simply like Alex. How can I fix this problem?

    I recommend loading data into a staging table where are values are strings.

    Then you can use a simply query to get the final results. In this case, you can do:

    select (case when name like 'N''%'''
             then substring(name, 2, len(name) - 3)
             else name
        end) as name
from staging

    There’s a better option for this. If the string delimiters and unicode indicators are consistent (they’re present on all rows), you should use a format file where you can indicate delimites for each column. This will allow you to set , N' as delimiter between the first and second columns, ', N' as delimiter for the second and third columns, and so on.
