Export query results into .csv file?

Question

Hello I have a T-SQL script that gets row counts for a specified date range and then needs to loop (by incrementing +1 day to get the next day's counts) for a large date range.  I'm aiming to output & append each query results day counts
into a .csv file via a SQL Agent job since this will take quite a while to complete.
Would using the following as an example template...
INSERT INTO OPENROWSET('Microsoft.ACE.OLEDB.12.0','Text;Database=D:\;HDR=YES;FMT=Delimited','SELECT * FROM [FileName.csv]')
SELECT Field1, Field2, Field3
FROM DatabaseName
...be the method or something else?
If this is good to use I've tried running this but get the following error:
Msg 7357, Level 16, State 2, Line 76
Cannot process the object "SELECT * FROM [FileName.csv]". The OLE DB provider "Microsoft.ACE.OLEDB.12.0" for linked server "(null)" indicates that either the object has no columns or the current user does not have permissions
on that object.
Thanks in advance.

Hi Techresearch7777777,
The error in your post says that the file FileName.csv has to be created with the column names in the first row. Like:
Field1,Field2,Field3
Either you can create a schema.ini file under the same folder:
 [FileName.csv]
 Format=CSVDelimited
 ColNameHeader=False
 Col1=Field1 [DataType]
 Col2=Field2 [DataType]
 Col3=Field3 [DataType]
For the [DataType],you can reference
Schema.ini File (Text File Driver)
If you have any question, feel free to let me know.
