Container for the parameters to the Select operation.
The Select
operation returns a set of attributes for ItemNames
that
match the select expression. Select
is similar to the standard SQL SELECT statement.
The total size of the response cannot exceed 1 MB in total size. Amazon SimpleDB
automatically adjusts the number of items returned per page to enforce this limit.
For example, if the client asks to retrieve 2500 items, but each individual item is
10 kB in size, the system returns 100 items and an appropriate NextToken
so
the client can access the next page of results.
For information on how to construct select expressions, see Using Select to Create Amazon SimpleDB Queries in the Developer Guide.
