loading text file into vertica and finding an issue with spaces between the values in columns

I am loading a text file into vertica using the copy command . It seems like the columns containing data in the database have spaces between the characters in the values.

copy test_schema.tabOne from local'testFile.txt' delimiter E'\t';

  • The way it looks in the database:

  • Please check the attached PNG. file. Can someone check the image and let me know why there are spaces between the characters in the columns of the field?

  • Hi Prasanna,

    I unfortunately can't see the attached PNG image...

    A couple thoughts here:

    - Is this possibly just an issue with output formatting?  You could look at the options in vsql (or in whatever tool you're using) to make sure it's displaying correctly.

    - Is the input file in UTF-8 format?  Vertica requires UTF-8 and may get confused by files in other encodings.  For example, if you load a UTF-16 file (and you're using mostly basic English characters), you'll see a null byte between each character, since for ASCII characters, UTF-16 looks exactly like UTF-8 with every other byte null.  (If you want to convert file formats, our "Iconverter" SDK example can do that for you as part of COPY; the "iconv" tool can do so at the command line.)

  • Thanks Adam, the file is in utf-16 format and I have converted it to utf-8 using "iconv" tool at the command line. The data looks fine in the db. I am just validating to see if there's a loss of data due to the conversion.
