Need help with a script to process a CSV file using SED and AWK
I get a CSV file every day with 2 columns and multiple rows
ex:
date1,date2 ( both the fields are varchar fields)
This data has to be updated in a table which is being done manually and i want to automate that.
1. I have to select all the data from the prod table( 2 columns { date1,date2}) into a staging table.
2. after that i have to insert the values from the CSV file into the table
3. run some validation procedures and then copy this data into prod table.
environment : sybase
OS: AIX(ksh)
I am having trouble getting data from CSV into to sybase table.
I tried to format the CSV file using SED and AWK with each column seperated by tab space and line seperated by newline.
"sed '1d' dates.txt | awk -F "," '{printf "%s\t%s\n",$1,$2}' > trial.txt"
but that gives me an when I bcp data into table. something to do with format.
any one has any idea what the right format to insert into 2 varchar columns?
or is there any other better way of doing this?

Both the fields are datetime fields.
I was thinking about storing the fields into variables and inserting these into the table using a loop.
any ideas about that ?

bb-csvinfo.cgi
BB-CSVINFO.CGI(1) General Commands Manual BB-CSVINFO.CGI(1)
NAME
bb-csvinfo.cgi - CGI program to show host information from a CSV file
SYNOPSIS
bb-csvinfo.cgi
DESCRIPTION
bb-csvinfo.cgi is invoked as a CGI script via the bb-csvinfo.sh CGI wrapper. Based on the parameters it receives, it searches a comma-
separated file for the matching host, and presents the information found as a table.
bb-csvinfo.cgi is passed a QUERY_STRING environment variable with the following parameters:
key (string to search for, typically hostname)
column (columnnumber to search - default 0)
db (name of the CSV database file in $BBHOME/etc/, default hostinfo.csv)
delimiter (delimiter character for columns, default semi-colon)
CSV files are easily created from e.g. spreadsheets, by exporting them in CSV format. You should have one host per line, with the first
line containing the column headings. Despite their name, the default delimiter for CSV files is the semi-colon - if you need a different
delimiter, invoke bb-csvinfo.cgi with the "delimiter=<character>" in the query string.
Example usage
This example shows how you can use the bb-csvinfo CGI. It assumes you have a CSV-formatted file with information about the hosts stored as
$BBHOME/etc/hostinfo.csv, and the hostname is in the first column of the file.
Use with the bbgen --docurl
The --docurl option to bbgen(1) sets up all of the hostnames on your Xymon webpages to act as links to a CGI script. To invoke the
bb-csvinfo CGI script, run bbgen with the option
--docurl=/cgi-bin/bb-csvinfo.sh?db=hostinfo.csv&key=%s
