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.
simpledb_select(SelectExpression, NextToken, ConsistentRead)A list with the following syntax:
list(
Items = list(
list(
Name = "string",
AlternateNameEncoding = "string",
Attributes = list(
list(
Name = "string",
AlternateNameEncoding = "string",
Value = "string",
AlternateValueEncoding = "string"
)
)
)
),
NextToken = "string"
)
[required] The expression used to query the domain.
A string informing Amazon SimpleDB where to start the next list of
ItemNames.
Determines whether or not strong consistency should be enforced when
data is read from SimpleDB. If true, any data previously written to
SimpleDB will be returned. Otherwise, results will be consistent
eventually, and the client may not see data that was written immediately
before your read.
