I'm not an SQL expert, but still believe this could all be done in SQL without needing awk or sed. And, you showed us the output you said you want with <space> as a field separator and then say that you want the output to be a CSV file with <comma> as the field separator??? Assuming that your input is in a file named file and that you do want output with <comma> as the field separator, the following awk script seems to do what I think you want:
Code:
awk -F'|' '			# Invoke awk and set input field separator to "|".
{	gsub(/^ | $/, "", $2)	# Get rid of leading and trailing space in date
				# and convert input FS (|) to output FS (space).
	gsub(/ /, "-", $2)	# Convert spaces to hyphens in date.
	gsub(/ +/, ",")		# Convert strings of adjacent spaces to commas.
	gsub(/^,|,$/, "")	# Get rid of leading and trailing commas.
	print			# Print updated lines.
}' file				# Close awk script and specify input file.

If file contains the input you showed us in post #1 in this thread, this produces the output:
Code:
Jan-8-2018-11:28PM,24,75,51,1,1.600
Jan-8-2018-12:01PM,52,823,21,6,2.675

You haven't told us what operating system or shell you're using (which you should always do in threads in this forum so we can suggest solutions that will work in your environment). If you're using a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk or nawk.

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
