READ using Binary Search

[Former Member]

Hi,

Is it necessary to use all the sorted keys in READ using BINARY SEARCH .

For EX: Sort it_tab BY key1 key2

While Reading i will use only key1 with BINARY SEARCH,Please tell me whether READ statement works?

Thanks,

It will work. Its not necessary that you will have to specify all the key fields in the READ statement

You can just hit F1 on READ and check the documentation.

Thanks for your reply, but in F1 there is nothing about sorted keys, i mean whether we need to use all the keys or few keys

Hello Ratish,

There isnt any hard and fast rule that you will have to use all the fields on which you sort. The key fields which you may want to use in the READ statement depends on the logic with which you are reading the internal table. As Rob pointed out its better to use all the fields which could make a record unique in the READ statement else it would keep reading only the first occurence of the record.

Thanks a loot vikranth for clearing my doubt, I had a doubt whether READ fails or not.

But you will only retrieve the first record that has that key.
