Bulk Insert Correctly Quoted CSV File in SQL Server

There is another solution for this   Consider the quotes as part of the fields delimiter  by editing the fmt file   You can check this out for more information   http   blogs msdn com b sqlserverfaq archive 2010 02 04 how-to-remove-unwanted-quotation-marks-while-importing-a-data-file aspx  An extract of the link above   The only way to remove the quotation marks would be to modify the column delimiters specified during the import operation  The only drawback here is that if you inspect the data to be inserted  you will very quickly realize that the column delimiters are different for each column  Delimiters highlighted above    So to specify different column delimiters for each column  you would need to use a format file if you plan to use Bulk Insert or BCP  If you generate a format file for the above table structure  it would be as follows   9 0 3 1       SQLCHAR       0       5         t      1     FName              SQL Latin1 General CP1 CI AS 2       SQLCHAR       0       5         t      2     LName              SQL Latin1 General CP1 CI AS 3       SQLCHAR       0       50        r n    3     Company            SQL Latin1 General CP1 CI AS   Modify the format file to represent the correct column delimiters for each column  The new format file to be used will look like this   9 0 4 1       SQLCHAR       0       0               0     FIRST QUOTE      SQL Latin1 General CP1 CI AS 2       SQLCHAR       0       5               1     FNAME               SQL Latin1 General CP1 CI AS 3       SQLCHAR       0       5               2     LNAME            SQL Latin1 General CP1 CI AS 4       SQLCHAR       0       50        r n   3     COMPANY          SQL Latin1 General CP1 CI AS

Per CSV format specification  I don t think it matters if data is correctly quoted or not  as long as it adheres to specification  Excessive quotes should be handled by the parser  if it s properly implemented  FIELDTERMINATOR should be comma and ROWTERMINATOR is line end - this denotes a standard CSV file  Did you try to import your data with these settings

You could also look at using OpenRowSet with the CSV text file data provider   This should be possible with any version of SQL Server    2005 although you need to enable the feature   http   social msdn microsoft com forums en-US sqldataaccess thread 5869d247-f0a0-4224-80b3-ff2e414be402

I ve spent half a day on this problem  It s best to import using SQL Server Import  amp  Export data wizard  There is a setting in that wizard which solves this problem  Detailed screenshots here  https   www mssqltips com sqlservertip 1316 strip-double-quotes-from-an-import-file-in-integration-services-ssis  Thanks

Been stung by the same    I wrapped this logic into a function to clean up data that had been was already imported DECLARE  str NVARCHAR MAX   DECLARE  quote identifier NVARCHAR MAX    SET  quote identifier   N  quot     SET  str   N  quot quoted stuff quot     SELECT IIF             LEFT  str  1     quote identifier            AND RIGHT  str  1     quote identifier             SUBSTRING  str  DATALENGTH  quote identifier   LEN  str  - DATALENGTH  quote identifier                str

I had this same problem  and I didn t want to have to go the SSIS route  so I found a PowerShell script that is easy to run and handles the case of the quotes with the comma in that particular field   Source Code and DLL for the PowerShell Script  https   github com billgraziano CsvDataReader  Here s a blog that explains the usage   http   www sqlteam com article fast-csv-import-in-powershell-to-sql-server

I know this is an old topic but this feature has now been implemented since SQL Server 2017  The parameter you re looking for is FIELDQUOTE  which defaults to      See more on https   docs microsoft com en-us sql t-sql statements bulk-insert-transact-sql view sql-server-2017

I had the same problem  with data that only occasionally double-quotes some text  My solution is to let the BULK LOAD import the double-quotes  then run a REPLACE on the imported data   For example   bulk insert CodePoint tbl  from  F  Data Map CodePointOpen Data CSV ab csv  with  FIRSTROW   1   FIELDTERMINATOR        ROWTERMINATOR   n     update CodePoint tbl  set Postcode   replace Postcode          where charindex     Postcode    0  To make it less painful to write the REPLACE script  just copy and paste what you need from the results of something like this   select C ColID  C  name  as Columnname into  Columns from syscolumns C join sysobjects T on C id   T id where T  name     User tbl  order by 1   declare  QUOTE char 1   set  QUOTE   Char 39   select  Update User tbl set   ColumnName   replace   ColumnName         QUOTE          QUOTE          QUOTE    QUOTE       GO  from  Columns where ColID  gt  2 order by ColID

Unfortunately SQL Server interprets the quoted comma as a delimiter  This applies to both BCP and bulk insert    From http   msdn microsoft com en-us library ms191485 28v sql 100 29 aspx     If a terminator character occurs within the data  it is interpreted as   a terminator  not as data  and the data after that character is   interpreted as belonging to the next field or record  Therefore    choose your terminators carefully to make sure that they never appear   in your data
