Question

Can anybody help me with the following line of code. I keep getting the Incorrect syntax near '\\' error:

 SET @filename = 
 ''BULK INSERT dbo.Tmp_Table 
  FROM ''\\SQL-300\ConvertedFiles\London\Figures\' 
  + @YEAR + '_' + @CLIENT+ '_' + @POLICYID + '.CSV'' 
  WITH (FIELDTERMINATOR = '','', ROWTERMINATOR = ''\n'', KEEPNULLS)''

Answer 1

Try this

SET @filename ='BULK INSERT dbo.Tmp_Table 
  FROM ''\\SQL-300\ConvertedFiles\London\Figures\' 
  + @YEAR + '_' + @CLIENT+ '_' + @POLICYID + '.CSV'' 
  WITH (FIELDTERMINATOR = '','', ROWTERMINATOR = ''\n'', KEEPNULLS)'

Answer 2

You can try something like this....

DECLARE @filename NVARCHAR(MAX);
DECLARE @Year     INT;
DECLARE @CLIENT   INT;
DECLARE @PLICYID  INT; 

SET @filename =  N'BULK INSERT dbo.Tmp_Table 
                  FROM ''\\SQL-300\ConvertedFiles\London\Figures\@YEAR_@CLIENT_@POLICYID.CSV '' 
                  WITH 
                    (FIELDTERMINATOR = '',''
                    ,ROWTERMINATOR = ''\n''
                    ,KEEPNULLS)'

EXECUTE  sp_executesql @filename
                      ,N'@Year INT, @Client INT, @PLICYID INT'
                      ,@Year
                      ,@CLIENT   
                      ,@PLICYID
