Just tell me my one question answer that Will you see that how indexing is work in server.
As indexing work logically into the server same the answer in question said that cluster index sorting the physical data into logical manner.
and also here sortin means not that sort ascending and descending it means that how indexing fetch data into their logical manner it has linked with data.

A table that does not have a clustered index is referred to as a HEAP and a table that has a clustered index is referred to as a clustered table. A clustered table provides a few benefits over a heap such as physically storing the data based on the clustered index, the ability to use the index to find the rows quickly and the ability to reorganize the data by rebuilding the clustered index.

i have one question

when did SQL server use the heap structure first time??

In the above explanation, U have said
“If index is created on table, the data stored in table is sorted logically and it is called as clustered index “.

Is it not that Clustered Index would sort the data physically rather than logically. Please correct me if I am wrong.

Thanks
Shown
