Dear friends,

I have input file , as shown above and I want to convert it into output, as shown above.
kindly let me know how to use sed command inside awk statement so that changes can be made.

the output is text file and output is to be aligned or formatted as table.

As this input file is received from MySQL query, and when it is converted to .csv file some columns file format gets changed ( column 2 and 3 are treated as general and is shown in decimal but they are numbers). Hence is it possible to set column format in unix for .csv file , so that I will not need it to save as .txt and can directly saved as .csv with ","separated file

thanks in advance

Mod Comment edit by bakunin: changed QUOTE-tags to CODE-tags. Please use these (not QUOTE-tags) for code, data and terminal output as they will not eat away white space and maybe preserve information which otherwise would be lost. Thank you.

What have you tried?

And, why haven't you written your MySQL query to directly produce output in the format you want?

I have tried to do it in sql server 2012 but the column length is flexible and I have also tried to get date format as desired from 100 to 114

now I am doing this


so that I can directly run awk command to remove spaces from my file.
but its not working.
i have also searched on net regarding this sed inside awk command and i came to know about gsub function but i am stuck in between.
Hence kindly help me, how to figure this out

So you want to do an SQL query followed by an awk script followed by a sed script. Hmmm - given the enormous formatting capabilities of usual SQL implementations, this doesn't seem too efficient.
MySQL provides the DATE_FORMAT(date, format_mask) function which would allow an immediately correct output. And the COLSEP (if I remember correctly) gives you control over the column separator character (e.g. ; ).

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:
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:

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.

I have already tried DATE_FORMAT(date, format_mask) function but it gives error

 'DATE_FORMAT' is not a recognized built-in function name.

Details of database are as below.

 Microsoft SQL Server Management Studio      11.0.2100.60
Microsoft Analysis Services Client Tools      11.0.2100.60
Microsoft Data Access Components (MDAC)      6.3.9600.16384
Microsoft MSXML      3.0 6.0 
Microsoft Internet Explorer      9.11.9600.17690
Microsoft .NET Framework      4.0.30319.34014
Operating System      6.3.9600

The sample input given, is output of query and I want to format it as given above.

Is it possible to use sed within awk statement or please let me how to do it with gsub function to get desired output.
