Answer Posted / kumar raja.
SEARCH ALL is an efficient one then why we need SEARCH ?
ONE EXAMPLE.
In VSAM files by passing the partial key we can search the
record using SEARCH or AEARCH ALL
But if you would like to point out 1st record with this
partial key, SEARCH will find the 1st record with that
partial key.
And SEARCH ALL will not. (95%)
Example. (Here my target to get 1st record with the
partial key. i.e (200 300 XXXXXXA)
VSAM File. (assume KEY as : ORG LOGO ACCOUNT) and
partial KEY (ORG = 200 LOGO = 300)
ORG LOGO ACCOUNT
100 222 XXXXXXXXX
100 333 XXXXX
111 333 XXXXXXX
200 300 XXXXXXA
200 300 XXXXXXB
200 300 XXXXC
200 300 XXXXXXD
250 300 XXXXXXX
300 340 XXXXXXX
In the case of search the O/P will be (200 300 XXXXXA)
Correct as per the requirement.
But in case of SEARCH ALL the response will be (200 300
XXXXXB). Wrong as per the requirement.
