What do you want to do with the very long SQL statements? Do you want to indent them on second/third lines?

BTW: This is what perl was designed for:
Code:
#!/usr/bin/perl
format =
@######  @<<<<<<<<  @<<<<<<<<<<<<<<<  ^<<<<<<<<<<<<<<<<<<<<<<<<<<<
$pid, $status, $datetime, $sql
~~       ^<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
$sql                                                                                           .
while (<>) {
  ($pid,$status,$datetime,$sql) = split(" ",$_,4);
  write;
}

pipe the output of awk into this program and save as your report. It will look real pretty Smilie

If you need more help with formatting, do man perlform

Jack, here's a break-down of the awk command:
Code:
awk 'NR==FNR{A[$1]=$2;next} A[$1]{$5=A[$1];print}'

In awk, NR is the total input lines seen, while FNR is the number of input lines seen in the current file. So this essentially means: if we're processing the first file, "do this" (the code in the first set of braces {...}).

That code sets an associate array to the value of the 2nd column (in the first file, remember), where the index is the 1st column -- which is common in both files.

Now do a "next" which means do not process any more code for the current line. This ensures the rest of the awk script is not executed for the first file.

So the first "pattern/program" applies to the first file -- and only the first -- while the second "pattern/program" applies to the second (and subsequent) file(s).

The second pattern/program looks at each line (in the second file) and if the first column is found in the array A, and if the value is not null or not blank, it runs the portion between the braces.

The code in the braces simply replaces the 5th field of that line with the contents of what was seen in line indexed by the first column in the first file.

NAME
vcf-compare - compare bgzipped and tabix indexed VCF files SYNOPSIS
compare-vcf [OPTIONS] file1.vcf file2.vcf ... DESCRIPTION
About: Compare bgzipped and tabix indexed VCF files. (E.g. bgzip file.vcf; tabix -p vcf file.vcf.gz) OPTIONS
-c, --chromosomes <list|file> Same as -r, left for backward compatibility. Please do not use as it will be dropped in the future. -d, --debug Debugging information. Giving the option multiple times increases verbosity -H, --cmp-haplotypes Compare haplotypes, not only positions -m, --name-mapping <list|file> Use with -H when comparing files with differing column names. The argument to this options is a comma-separated list or one mapping per line in a file. The names are colon separated and must appear in the same order as the files on the command line. -R, --refseq <file> Compare the actual sequence, not just positions. Use with -w to compare indels. -r, --regions <list|file> Process the given regions (comma-separated list or one region per line in a file). -s, --samples <list> Process only the listed samples. Excluding unwanted samples may increase performance considerably. -w, --win <int> In repetitive sequences, the same indel can be called at different positions. Consider records this far apart as matching (be it a SNP or an indel). -h, -?, --help This help message. vcf-compare 0.1.5 July 2011 VCF-COMPARE(1)
