Hi All,
I am apparently totally misreading how to import data using the COPY FROM command, can someone give assistance ?
I have two issues, both dealing with double quotes as NULL. The data is CSV with NULL being represented by a double quote (e.g. "") in all columns of the table.
ISSUE A) The following command bombs:
COPY testdata FROM 'c:/temp/test.csv' CSV HEADER;
with the following error:
ERROR: invalid input syntax for type double precision: ""
CONTEXT: COPY testdata, line 7, column latitude: ""
********** Error **********
ERROR: invalid input syntax for type double precision: ""
SQL state: 22P02
Context: COPY testdata, line 7, column latitude: ""
So, latitude is a double precision column and I think that PostgreSQL is interpreting the double quote as a NULL string and then it can not be placed into that column because it is a double precision column.
Issue B) I have an associated issue with a text value where the NULL in the data being represented by a double quote (e.g. "") is being inputed as a quote. I can not use the switch NULL AS '"' because PostgreSQL says "the quote character must not appear in the NULL specification"
Given the file sizes are huge, I would rather not have to try to preprocess the data. Is there anyway the COPY FROM command can handle this data smoothly ?
