Need code for updating second record to first record in shell scripting
Hi,,

I have requirement that i need to get DISTINCT values from a table and if there are two records i need to update it to one record and then need to submit INSERT statements by using the updated value as a parameter. Here is the example follows..

Code:
SELECT DISTINCT ID FROM OFFER_GROUP WHERE OFFERS IN('A','B');

Result as follows
Code:
ID
1
11

Above statement always displays 1 or 2 records.If the above query returns 2 rows then i need to update it to 1 row like below

Code:
UPDATE OFFER_GROUP SET ID =1 WHERE OFFERS IN('A','B') AND ID =11;

And then i need to execute INSERT statements by using ID as a parameter.
whenever i use ${ID} it should be place with the updated value 1.

insert into <TABLE>values ();

For the above requirement, i need to implement it in shell scripting and i am using nzsql.

Thanks in advance.

Cheers,
Samah

ldns-read-zone

ldns-read-zone(1)					      General Commands Manual						 ldns-read-zone(1)

NAME

       ldns-read-zone - read a zonefile and print it

SYNOPSIS

       ldns-read-zone ZONEFILE

DESCRIPTION

       ldns-read-zone reads a DNS zone file and prints it. The output has 1 resource record per line, and no pretty-printing makeup.

OPTIONS

       -c     Canonicalize all resource records in the zone before printing

       -d     Only  print  DNSSEC  data from the zone. This option skips every record that is not of type NSEC, NSEC3, RRSIG or DNSKEY. DS records
	      are not printed.

       -h     Show usage and exit

       -n     Do not print the SOA record

       -s     Strip DNSSEC data from the zone. This option skips every record that is of type NSEC, NSEC3, RRSIG or DNSKEY. DS records	are  still
	      printed.

       -S [[+|0]number | YYYYMMDDxx | unixtime ]
	      Set  serial  number  to  the  given number, or when preceded by a sign, offset the exisiting number with it. When giving the literal
	      strings YYYYMMDDxx or unixtime, the serial number is tried to be reset in datecounter or in unixtime format respectively. Though	is
	      the updated serial number is smaller than the original one, the original one is simply increased by one.

	      When updating a serial number, records of type NSEC, NSEC3, RRSIG and DNSKEY will be skipped when printing the zone.

       -v     Show the version and exit

       -z     Sort the zone before printing (this implies -c)
