Sean, Use sql select to find out duplicates. Regards Allen On 11/12/11 12:01 PM, "Sean McNamara" wrote:

I tried that (as both the normal dbuser and as admin). Both fail the same way but don't give an indicator of where it feels the constraint is violated:

$ mclient -u monetdb -s "alter table mduser.testdata add constraint testdata_pkey primary key (foo,epoch);" testdb password: SQLException:assert:UPDATE: PRIMARY KEY constraint 'testdata.testdata_pkey' violated

How about add constraint after you import? I think it might tell you which one had problem.

Brilliant suggestion, and I think it exposed the problem.

$ mclient -u monetdb -s "copy into mduser.testdata from '/tmp/testdata2.csv' using delimiters ',','\n','\'';" testdb password: SQLException:importTable:value 'ONE_SECOND' from line 12734 field 3 not inserted, expecting type varchar(8) failed to import table

It looks like the field I created is too small to handle some of the values in the file. After expanding all the varchar fields to 32 and re-running, I get a different error:

$ mclient -u monetdb -s "copy into mduser.testdata from '/tmp/testdata2.csv' using delimiters ',','\n','\'';" testdb password: SQLException:assert:INSERT INTO: PRIMARY KEY constraint 'testdata.testdata_pkey' violated

That makes me think I have duplicate data. The PKEY is comprised of fields #1 and #5, so I check for that but it looks fine:

$ cat /tmp/testdata2.csv | cut -d, -f1,5 |uniq -d $

However if I drop and re-add the table without the constraint, it works:

sql>create table testdata ( more> foo varchar(32), more> bar varchar(32), more> baz varchar(32), more> woz varchar(32), more> epoch bigint more>); operation successful (1.477ms) sql>\q $ mclient -u monetdb -s "copy into mduser.testdata from '/tmp/testdata2.csv' using delimiters ',','\n','\'';" testdb password: 2519931 affected rows

Thanks Allen! This gets me able to import. Now I'm wondering what might be wrong with the constraint. Any insight there?

What about just issue the following:

mclient -s "copy into testdata from '/tmp/testdata2.csv' using delimiters ',','\n','\'';"

Thanks Allen. Red-herring there. My first file had "SPY" in the first column, and the second had "testdata1", so the difference there is just because of the contents. If I convert the original SPY file and re-run, I get the same behavior.

$ mclient -s "copy into testdata from STDIN using delimiters ',','\n','\'';" testdb - < /tmp/testdata2.csv syntax error, unexpected STRING in: "'SPY'"

Hi Sean,

You should inspect your data quality, it seems in the first 3 imports, it stopped at "spy", I suspect it might be some \t in that supposed to be string, and last import you put single-quote around string, then it stopped at "testvalue1", search your import file, look for that "testvalue1", the problem should around there, maybe an extra field because wrong replace by sed.

Best Regards Allen
