DataAbstractService

Overview

This is the base class of all standard Data Abstract services.

It provides pre-defined methods that clients can use to read data stored in a database, to apply updates, execute commands and more.

A Data Abstract service references a Schema (see the ServiceSchemaName property) in which all the data elements it handles are defined. For instance, if you were to define a Customer Manager service, you would have it point to a schema where data tables such as Customers and Customer Details are defined. The same schema might contain commands that wrap specific insert or delete statements to update those tables too.

When a data abstract service is instantiated and the AcquireConnection property is set to true, the code of your methods can reference the Connection property which will already be initialized for you. The connection the service auto-creates is one of those defined in the server connection manager: you instruct the service to create a certain connection by setting the ConnectionName property.

AcquireConnection

Toggles whether the service can automatically acquire a connection when it is activated. If set to true, the service will automatically obtain a connection to be used for data access whenever the service is activated and will automatically release the connection when the service is deactivated. The name specified in ConnectionName will determine what type of connection will be acquired; the Connection property will give access to the current connection.

AfterBeginTransaction

Occurs after the service acquires a connection and begins a transaction. A transaction is automatically started when deltas are being processed by a call to UpdateData. The same transaction is either committed or rolled back at the end of the method call, depending on the delta having been processed successfully or not. You can use the connection's CurrentTransaction property to access the active transaction, for example to configure the transaction.

AllowCustomSqlMacros

 

property AllowCustomSqlMacros: Boolean read write;

 

Boolean AllowCustomSqlMacros { get; set; }

 

Property AllowCustomSqlMacros() As Boolean

AllowDataAccess

Allows the clients to access Schema information from the published schema (true, default) or not(false).

 

property AllowDataAccess: Boolean read write;

 

Boolean AllowDataAccess { get; set; }

 

Property AllowDataAccess() As Boolean

AllowDynamicSelect

 

property AllowDynamicSelect: Boolean read write;

 

Boolean AllowDynamicSelect { get; set; }

 

Property AllowDynamicSelect() As Boolean

AllowDynamicWhere

Allows clients to use Dynamic Where feature.

 

property AllowDynamicWhere: Boolean read write;

 

Boolean AllowDynamicWhere { get; set; }

 

Property AllowDynamicWhere() As Boolean

AllowExecuteCommands

Allows clients to execute commands that are published in the Schema (true) or not (false, default).

Set this property to true if you want to enable clients to manually execute commands defined in the ServiceSchema.

 

property AllowExecuteCommands: Boolean read write;

 

Boolean AllowExecuteCommands { get; set; }

 

Property AllowExecuteCommands() As Boolean

AllowExecuteDASQL

 

property AllowExecuteDASQL: Boolean read write;

 

Boolean AllowExecuteDASQL { get; set; }

 

Property AllowExecuteDASQL() As Boolean

AllowExecuteSQL

Gets or sets a flag indicating whether direct access to the underlying database is allowed.

When set to true allows execution of custom SQL queries as commands or for retrieving data bypassing the published server schema via the SQLGetData, SQLGetDataEx, SQLExecuteCommand and DataAbstractService#SQLExecuteCommandEx%% methods.

Note: Enabling this option opens a huge security risk as client applications can send any custom SQL text to the server for execution, including code that could potentially harm or even destroy the database.

The default value is false.

 

property AllowExecuteSQL: Boolean read write;

 

Boolean AllowExecuteSQL { get; set; }

 

Property AllowExecuteSQL() As Boolean

AllowHttpSchemaAccess

Using this property, you can allow or forbid access to the service schema by any client over HTTP protocol When AllowHttpSchemaAccess is set to True, the service schema could be retrieved via urls like http://myserver:8099/MyDAService

If you don't want to allow clients to get your service schema directly via HTTP (usually this can be a security issue), you need to set AllowHttpSchemaAccess to false and the server will raise a proper exception when somebody tries to get access to the service schema via HTTP.

You should understand the difference between AllowSchemaAccess and AllowHttpSchemaAccess properties. While AllowSchemaAccess property manages access to the Service Schema in general, AllowHttpSchemaAccess manages access to the Service Schema via HTTP only. That said you should have both these properties set to True for accessing service schema via HTTP.

Obviously this option is applicable only when the server is using http-based server channels.

 

property AllowHttpSchemaAccess: Boolean read write;

 

Boolean AllowHttpSchemaAccess { get; set; }

 

Property AllowHttpSchemaAccess() As Boolean

AllowSchemaAccess

Allows clients to access data from the published Schema (true, default) or not (false). Access to schema information from the server is often helpful while designing the client application since most clients do not need to refresh schema information from the server at runtime.

Although proper use of user authentication will restrict access, disabling this option for production servers prevents unnecessarily exposing the server schema to the outside world.

 

property AllowSchemaAccess: Boolean read write;

 

Boolean AllowSchemaAccess { get; set; }

 

Property AllowSchemaAccess() As Boolean

AllowUpdates

 

property AllowUpdates: Boolean read write;

 

Boolean AllowUpdates { get; set; }

 

Property AllowUpdates() As Boolean

AutoCreateBusinessProcessors

Instructs the service to create a business processor for each of the data tables that are being updated in an UpdateData call, if no explicit BusinessProcessor has been dropped at design time.

Set this property to true to allow automatic handling of updates to all data tables; set it to false to only allow data updates through manually configured BusinessProcessor components dropped onto your service.

 

property AutoCreateBusinessProcessors: Boolean read write;

 

Boolean AutoCreateBusinessProcessors { get; set; }

 

Property AutoCreateBusinessProcessors() As Boolean

AcquireConnection

Toggles whether the service can automatically acquire a connection when it is activated. If set to true, the service will automatically obtain a connection to be used for data access whenever the service is activated and will automatically release the connection when the service is deactivated. The name specified in ConnectionName will determine what type of connection will be acquired; the Connection property will give access to the current connection.

 

property AcquireConnection: Boolean read write;

 

Boolean AcquireConnection { get; set; }

 

Property AcquireConnection() As Boolean

AllowCustomSqlMacros

 

property AllowCustomSqlMacros: Boolean read write;

 

Boolean AllowCustomSqlMacros { get; set; }

 

Property AllowCustomSqlMacros() As Boolean

AllowDataAccess

Allows the clients to access Schema information from the published schema (true, default) or not(false).

 

property AllowDataAccess: Boolean read write;

 

Boolean AllowDataAccess { get; set; }

property AllowDynamicWhere: Boolean read write;

 

Boolean AllowDynamicWhere { get; set; }

 

Property AllowDynamicWhere() As Boolean

AllowExecuteCommands

Allows clients to execute commands that are published in the Schema (true) or not (false, default).

Set this property to true if you want to enable clients to manually execute commands defined in the ServiceSchema.

 

property AllowExecuteCommands: Boolean read write;

 

Boolean AllowExecuteCommands { get; set; }

 

Property AllowExecuteCommands() As Boolean

AllowExecuteDASQL

 

property AllowExecuteDASQL: Boolean read write;

 

Boolean AllowExecuteDASQL { get; set; }

 

Property AllowExecuteDASQL() As Boolean

AllowExecuteSQL

Gets or sets a flag indicating whether direct access to the underlying database is allowed.

When set to true allows execution of custom SQL queries as commands or for retrieving data bypassing the published server schema via the SQLGetData, SQLGetDataEx, SQLExecuteCommand and DataAbstractService#SQLExecuteCommandEx%% methods.

Note: Enabling this option opens a huge security risk as client applications can send any custom SQL text to the server for execution, including code that could potentially harm or even destroy the database.

The default value is false.

 

property AllowExecuteSQL: Boolean read write;

 

Boolean AllowExecuteSQL { get; set; }

 

Property AllowExecuteSQL() As Boolean

AllowHttpSchemaAccess

Using this property, you can allow or forbid access to the service schema by any client over HTTP protocol When AllowHttpSchemaAccess is set to True, the service schema could be retrieved via urls like http://myserver:8099/MyDAService

If you don't want to allow clients to get your service schema directly via HTTP (usually this can be a security issue), you need to set AllowHttpSchemaAccess to false and the server will raise a proper exception when somebody tries to get access to the service schema via HTTP.

You should understand the difference between AllowSchemaAccess and AllowHttpSchemaAccess properties. While AllowSchemaAccess property manages access to the Service Schema in general, AllowHttpSchemaAccess manages access to the Service Schema via HTTP only. That said you should have both these properties set to True for accessing service schema via HTTP.

Obviously this option is applicable only when the server is using http-based server channels.

 

property AllowHttpSchemaAccess: Boolean read write;

 

Boolean AllowHttpSchemaAccess { get; set; }

 

Property AllowHttpSchemaAccess() As Boolean

AllowSchemaAccess

Allows clients to access data from the published Schema (true, default) or not (false). Access to schema information from the server is often helpful while designing the client application since most clients do not need to refresh schema information from the server at runtime.

Although proper use of user authentication will restrict access, disabling this option for production servers prevents unnecessarily exposing the server schema to the outside world.
