Hi,

Is it possible for the COPY command to read data from a file, but skip
specific columns?


You can use awk to skip fields and create an intermediate file or better yet, just pipe the output to copy. Here is a trivial example:


  awk '{ FS = "\t" ; OFS = "\t" ; print $1,$3 }' inputdatafile

This sets the input and output field separators to tab and outputs the first and third fields from inputdatafile. If you want to skip the first record just add the following if statement:

awk '{ FS = "\t" ; OFS = "\t" ; if ( NR > 1 ) print $1,$3 }' inputdatafile
