The most common problem with csv files are syntax errors in the file. I tells that it is expecting 476 columns and only got 138. apparently at the first row, If that row is header information, you can use the SKIP functionality of the COPY command.

Hello, I'm pretty new to MonetDB and I'm trying to perform what seems like it should be a relatively straightforward inner join between two tables.

I would like to merge the two Alaska files from the American Community Survey --

http://www2.census.gov/acs2010_1yr/pums/csv_hak.zip contains a CSV file with one record per household http://www2.census.gov/acs2010_1yr/pums/csv_pak.zip contains a CSV file with one record per personThese two files should be merged on the field "serialno"

I am working on Windows 7 x64. Here's the contents of my mserver5.exe window:

# MonetDB 5 server v11.11.11 "Jul2012-SP2" # Serving database 'demo', using 2 threads # Compiled for x86_64-pc-winnt/64bit with 64bit OIDs dynamically linked # Found 3.905 GiB available main-memory. # Copyright (c) 1993-July 2008 CWI. # Copyright (c) August 2008-2012 MonetDB B.V., all rights reserved # Visit http://www.monetdb.org/ for further information # Listening for connection requests on mapi:monetdb://127.0.0.1:50000/ http://127.0.0.1:50000/ # MonetDB/SQL module loaded

...

The following commands..

1. create a person-level table

2. create a household-level table

3. read the person-level CSV into the person table

4. read the household-level CSV into the household table

5. attempt to print the first five records with "select * from tablename

limit 5" -- sometimes these work, sometimes they don't.

6. merge the two tables together

7. attempt to print the first five records of the merged table

Unfortunately, I'm getting an error that I can't find with web searches.. The only place I can even find this error is http://bugs.monetdb.org/show_bug.cgi?id=2963 -- and that seems both time-related and fixed long ago.. I doubt it's a bug, I'm probably just making a beginner's mistake.

invalid tuple received from server, got 138 columns, expected 476, ignoring +------+------+------+------+-------+------+---------+---------+------+------+ 1 tuple (417.984ms) !466 columns dropped! note: to disable dropping columns and/or truncating fields use \w-1

Even after setting \w to -1, the number of columns returned gets limited, crashing my program.

I am ultimately trying to work with the new R/MonetDB package (which uses Java and is available from http://sqlsurvey.r-forge.r-project.org/), but none of the table interactivity will work until I'm able to return all of the columns properly.

Any advice would be appreciated! Thanks!!!
