DescribeTable
The following code will display all the table schema of the table with the name
Tbl_Book
. As hinted in the
CreateTable
command, the response of the
DescribeTable
and
CreateTable
requests will be similar (except
TableStatus
).
After performing the
CreateTable
request,
TableStatus
will be
CREATING
. So if
we describe the same table after a point of time (once the table has become active), its
status will become
ACTIVE
.
Have a look at the following code:
{
"TableName":"Tbl_Book"
}
The following is the output of
DescribeTable
with
TableStatus
as
ACTIVE
:
