[MonetDB-users] Copy Into problem
Hi there,
I'm trying to use the copy into with csv file (utf-8 encoded) and I encounter some problem. The create statement is:
CREATE TABLE "sa3e7e9f4d666429ea2c5bb61a532f5b9" ("A" DATE ,"B" VARCHAR (22) ,"C" DECIMAL (12, 5) ,"D" DECIMAL (12, 5) ,"E" DECIMAL (12, 5) ,"F" DECIMAL (12, 5) )
The copy into statement is:
COPY INTO "sa3e7e9f4d666429ea2c5bb61a532f5b9" FROM 'T:\Prism\Applications\Desktop\PrismDesktop\bin\Debug\LocalRepository\ImportedCSV\ImportedCSV0.csv' USING DELIMITERS '|' NULL AS 'A56A9FC261A143a48F6019F602ABF409';
And csv is attached.
Any advice?!?!?!
tnx,
Alfred. http://www.nabble.com/file/p21200441/ImportedCSV0.csv ImportedCSV0.csv

Do you have any error message? I suspect the DATETIME to be a problem, as your table specifies a DATE, but my knowledge on SQL's date/time/timezone stuff is a bit rusty.
Hi Fabian,
The error i get is: !SQLException:sql:value '?»¿1997-01-01 00:00:00' while parsing '?»¿1997-01-01 00:00:00|City Mall|1110|6165|33|8122' from line 0 field 0 not inserted, expecting type date !SQLException:importTable:failed to import table
It seems like some chars (?»¿) are added to the first row inserted to the table. The chars do not appear in the csv file (attached).

Yeah, looks like garbage in the rendering. But I think the most important part is "expecting type date". You specified a datetime. If you want to really have date (1997-01-01) you need to change your CSV (remove the 00:00:00), or do the modification in the database after loading your dataset with a datetime instead of a date for column "A".
Hi Fabian,
It happens even if i change the table declartion so that column A is timestamp.

The last couple of days the COPY functionality has been improved and made more robust. It might be that you hit one of the bugs solved. The following experiment runs:
mk> mclient -lsql sql>create table tmp_date ( d timestamp, s string); 0 tuples sql>COPY 1 RECORDs INTO tmp_date FROM stdin USING DELIMITERS '|', '\n'; more>1997-01-01 00:00:00|City Mall Rows affected 1 sql>select * from tmp_date; +----------------------------+-----------+ | d | s | +============================+===========+ | 1997-01-01 00:00:00.000000 | City Mall | +----------------------------+-----------+ 1 tuple

With less you can see the following first chars <U+FEFF>.

looks like some "magic byte" (-like) file type identifier left over by some nasty (Windows-?) program that created the csv file ...
http://en.wikipedia.org/wiki/Magic_number_(programming) says: " Unicode text files encoded in UTF-16 often start with the Byte Order Mark to detect endianness ('FE FF' for big endian and 'FF FE' for little endian). UTF-8 text files often start with the UTF-8 encoding of the same character, 'EF BB BF'. "

Vim ignores it, so maybe we should as well?
I haven't looked at your document, but it is probably the byte-order mark...
See section: 3.2 Byte order mark (BOM) http://www.ietf.org/rfc/rfc2781.txt
Normal editors/viewers hide it, as it isn't a visible character. I think MonetDB should have stripped it before showing you the error message.

If "magic numbers" and/or "byte order marks" are indeed to be expected in *plain* text (csv) files, then yes, ortherwise, it could only mention that the file does not comply to the expected *plain* text format.

I haven't looked at your document, but it is probably the byte-order mark...
See section: 3.2 Byte order mark (BOM) http://www.ietf.org/rfc/rfc2781.txt
Normal editors/viewers hide it, as it isn't a visible character. I think MonetDB should have stripped it before showing you the error message.
If "magic numbers" and/or "byte order marks" are indeed to be expected in *plain* text (csv) files, then yes, ortherwise, it could only mention that the file does not comply to the expected *plain* text format.
Stefan's €0.02 ;-)
Could argue that since we only support UTF-8, we should try to support UTF-8 files in all kinds of flavours, or not?
