Introduction

The purpose of Service Data Objects (SDOs) is to provide the ability to securely execute SQL on the database server from Aptify Web and Aptify SOA, returning the results to the caller.  The flexibility of being able to execute SQL statements, including stored procedures, without opening up the service layer to SQL injection attacks is a powerful feature in Aptify SOA.  System administrators and developers have control over which SQL statements can be executed through the Services Data Objects Entity.  Service Data Objects are executed by Name, not the SQL that executes.  Aptify SOA looks up the Service Data Object, confirms that the current platform and User are allowed to execute the Service Data Object, retrieves the SQL statement from the Service Data Object record, executes it and returns the results to the caller.

Generally Service Data Objects are a good choice for providing data when leveraging an Aptify Views is not appropriate. 

How to Create Service Data Object

...

1. Create a Database Object to hold the SQL you want to execute.

2. Create a new Service Data Objects record. (The Service Data Objects service is available in the Web Services application.) 

   • Name: The name to use when accessing the Service Data Object. Generally this will be identical to the Name of the Database Object used by the Service Data Object.
   • SQL: The SQL the Service Data Object should execute. Call the Database Object you created in step 1 here.

   Choose whether to apply Application Filters to the Service Data Object. This will restrict use of the Service Data Object to a particular Service Application.

3. To apply Application Filters, select the Enable Application Filters option on the General tab and specify which applications can access the object on the Applications tab.

   Choose whether to apply Security to the Service Data Object. This will restrict the use of the Service Data Object to the chosen Users, Groups, and/or Web Groups. (Of course, this is an additional level of restriction on top of the Grant SQL in the Database Object.) 

   
   

4. To apply Security, select the Enable Security option on the General tab. If security is enabled then add at least one record on the Security tab.

5. If the Database Object (or other SQL) requires parameters, enter each parameter on the Parameters tab. Use the Name of the parameter as it is defined in the SQL.

   The Service Data Object is now created. You can call it via Aptify Javascript API or via Aptify SOA.

Calling Service Data Object from Aptify SOA:

Headers

...

Header:

you need to pass AptifyAuthorization header in order to receive search results, you must send the AptifyAuthorization header.

End Point

Example Endpoint

https://<service base>/services/DataObjects/{Service DataObject Name}

Parameters defined in the SDO object need to be appended to the URL as a query string. Parameters should be the same as those defined in the SDO object.

Endpoint Example With Parameters

https://<service base>/services/DataObjects/{Service DataObject Name}?ParameterName1=value1&ParameterName2=Value2&....

Sample End Point(Execute spGetCompanyAccountSummary SDO):

The following example illustrates how to execute the " spGetCompanyAccountSummary " stored procedure as an endpoint. This example expects two parameters which are defined in the Web Service Application. The parameters are companyId (10) and Convertmulticurrency (false).

...

 https://<service base>/services/DataObjects/spGetCompanyAccountSummary?CompanyID=10&Convertmulticurrency=false

Sample Response Body 

The search results are represented as a JSON array of JSON objects, where each object contains record data. The properties of the objects will be some of the fields of the record, always including the ID and Name field.

Here is sample result Response data for spGetCompanyAccountSummary data object.

{
"dataObjectName":"spGetCompanyAccountSummary",
 "results":
	[
		{
			"OrderTotal":xxxx.xxxx,
			"PaymentTotal":xxxx.xxxx,
			"BalanceTotal":xxxx.xxxx
		}
	]
}
