Amazon SimpleDB - Get attributes

Declaration

<AMAWSSIMPLEDB ACTIVITY="get_attributes" PROVIDER="text (options)" SESSION="text" ACCESSKEY="text" SECRETKEY="text (encrypted)" USERAGENT="text" MAXERRORRETRY="number" SERVICEURL="text" PROXYHOST="text" PROXYPORT="number" PROXYUSER="text" PROXYPWD="text (encrypted)" SIGNMETHOD="text" SIGNVERSION="number" DOMAIN="text" ITEM="text" RESULTDATASET="text" ATTR="text" CONSISTENTREAD="YES/NO" />

Description

Returns the attributes and values associated with an item and populates a dataset with the results. Optionally, the attributes returned can be limited to one or more specified attribute name parameters. A Loop - Dataset step can be used to loop through each row of data populated by the specified dataset in order to perform specific operations on them.

IMPORTANT: AutoMate's SimpleDB activities use Amazon's SimpleDB engine to perform their work, therefore, launching and operating Amazon SimplDB through AutoMate requires a valid Access Key ID and Secret Access Key.

Practical Usage

Used to get attributes of an item.

Parameters

Connection

Property Type Required Default Markup Description
Connection --- --- --- --- Indicates where Automate Web Service WS user credentials and preferences should originate from. This is a design mode parameter used only during task construction and configuration, thus, comprises no markup. The available options are:
  • Host (default) - Specifies that user credentials and/or advanced preferences are configured individually for this activity. This option is normally chosen if only a single activity is required to complete an operation.
  • Session - Specifies that user credentials and/or advanced preferences are obtained from a pre-configured session created in an earlier step with the use of the SimpelDB - Create session activity. This option is normally chosen if a combination of related activities are required to complete an operation. Linking several activities to a single session eliminates redundancy. Additionally, a single task supports construction and simultaneous execution of multiple sessions, improving efficiency.
Session Text Yes, if the Connection parameter is set to Session SQSSession1 SESSION="SimpleDBSession1" The name of an existing session to attach this activity to. This parameter is active only if the Connection parameter is set to Session. The default session name is SimpleDBSession1.
Access key Text Yes, if the Connection parameter is set to Host (Empty) ACCESSKEY="022QF06E7MXBSH9DHM02" A 20-character alphanumeric string that uniquely identifies the owner of the AWS service account, similar to a username. This key along with a corresponding secret access key forms a secure information set that AWS uses to confirm a valid user's identity. This parameter is active only if the Connection parameter is set to Host.
Secret access key Text Yes, if the Connection parameter is set to Host (Empty) SECRETKEY="kWcrlUX5JEDGM/LtmEENI/aVmYvHNif5zB+d9+ct" A 40-character string that serves the role as password to access the AWS service account. This along with an associated access key forms a secure information set that SQS uses to confirm a valid user's identity. This parameter is active only if the Connection parameter is set to Host.
User agent Text No Automate USERAGENT="Automate" The name of the client or application initiating requests to AWS, which in this case, is Automate. The default value is Automate. 
Maximum number of retries on error Number No (Empty) MAXERRORRETRY="4" The total amount of times this activity should retry its request to the server before returning an error. Network components can generate errors anytime in the life of a request, thus, implementing retries can increase reliability. 
Service URL Text No (Empty) SERVICEURL="https://sdb.eu-west-1.amazonaws.com" The URL that provides the service endpoint. To make the service call to a different region, you can pass the region-specific endpoint URL. For example, entering  https://sdb.us-west-1.amazonaws.com points to US West (Northern California) region. Refer to SimpleDB Endpoints and Regions for a complete list of SQS regions, along with their associated endpoints and valid protocols..
Proxy host Text No (Empty) PROXYHOST="proxy.host.com" The host name (for example, server.domain.com) or IP address (for example, 192.168.0.100) of the proxy server to use when connecting to AWS.  
Proxy port Number No (Empty) PROXYPORT="1028" The port that should be used to connect to the proxy server.
Proxy username Text No (Empty) PROXYUSER="username" The username that should be used to authenticate connection with the proxy server (if required).
Proxy password Text No (Empty) PROXYPWD="encrypted" The password that should be used to authenticate connection with the proxy server (if required).
Signature method Text No (Empty) SIGNMETHOD="HmacSHA256" The signature method to use for signing the request. This provides a valid hashing algorithm for signature calculation. Acceptable AWS signature methods are HmacSHA1 and HmacSHA256.
Signature version Number No (Empty) SIGNVERSION="2" The signature version for signing the request. Valid AWS signature versions are 2 and 4. The difference with version 4 is that it allows you to sign your message using a key that is derived from your secret access key rather than using the secret access key itself.

Data

Property Type Required Default Attributes Description
Domain Name Text Yes (Empty) DOMAIN="myDomain" The name of the domain in which to perform the operation.
Item Name Text Yes (Empty) ITEM="records" The item to retrieve attributes from.
Attributes Text No (Empty) ATTR="January" The name of the attribute to retrieve.
Consistent Read Yes/No No No CONSISTENTREAD="yes" If selected, ensures that the most recent data is returned. Disabled by default.
Create and populate dataset with SimpleDB attribute information Text No (Empty) RESULTDATASET="theDatase" The name of the dataset to create and populate with attribute values.
