DataBind Controls to Sage Intacct データ in C++Builder
DataBind to Sage Intacct のデータ in C++Builder with standard components and controls.
最終更新日：2023-06-12The CData ODBC Driver for Sage Intacct makes it easy to integrate connectivity to live Sage Intacct のデータ with standard data access components in C++Builder. This article shows how to create a simple visual component library (VCL) application in C++Builder that connects to Sage Intacct のデータ, executes queries, and displays the results in a grid. An additional section shows how to use FireDAC components to execute commands from code.
Create a Connection to Sage Intacct データ
If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.
Sage Intacct 接続プロパティの取得・設定方法
独自のWeb サービスクレデンシャル、埋め込みクレデンシャル（Basic 認証）、またはOkta クレデンシャルのいずれかを使用して、Sage Intacct への接続を確立できます。
Sage Intacct への認証
Sage Intacct は2種類の認証をサポートします。Basic およびOkta です。選択した認証方法に関連するプロパティを設定して、接続を構成します。
Basic 認証
Basic 認証スキームでは、埋め込みクレデンシャルを使用してデータの読み書きが可能です。オプションとして、独自のWeb サービスクレデンシャルを指定することもできます。
Basic 認証を使用して認証を行うには、以下のプロパティを設定します。
- AuthScheme：Basic。
- CompanyID：Sage Intacct にログインする際に会社を識別するために使用するID。
- User：Sage Intacct へのログインに使用するログイン名。
- Password：ログインクレデンシャル用のパスワード。
- （オプション）SenderID およびSenderPassword：Web サービスのSender ID およびパスワード。
You can then follow the steps below to use the Data Explorer to create a FireDAC connection to Sage Intacct.
- In a new VCL Forms application, expand the FireDAC node in the Data Explorer.
- Right-click the ODBC Data Source node in the Data Explorer.
- Click Add New Connection.
- Enter a name for the connection.
- In the FireDAC Connection Editor that appears, set the DataSource property to the name of the ODBC DSN for Sage Intacct.
Create VCL Applications with Connectivity to Sage Intacct データ
Follow the procedure below to start querying Sage Intacct のデータ from a simple VCL application that displays the results of a query in a grid.
-
Drop a TFDConnection component onto the form and set the following properties:
- ConnectionDefName: Select the FireDAC connection to Sage Intacct.
- Connected: Select True from the menu and, in the dialog that appears, enter your credentials.
-
Drop a TFDQuery component onto the form and set the properties below:
- Connection: Set this property to the TFDConnection component, if this component is not already specified.
SQL: Click the button in the SQL property and enter a query. For example:
SELECT Name, TotalDue FROM Customer- Active: Set this property to true.
Drop a TDataSource component onto the form and set the following property:
- DataSet: In the menu for this property, select the name of the TFDQuery component.
-
Drop a TDBGrid control onto the form and set the following property:
- DataSource: Select the name of the TDataSource.
- Drop a TFDGUIxWaitCursor onto the form — this is required to avoid a run-time error.
Execute Commands to Sage Intacct with FireDAC Components
You can use the TFDConnection and TFQuery components to execute queries to Sage Intacct のデータ. This section provides intacctspecific examples of executing queries with the TFQuery component.
Connect to Sage Intacct データ
To connect to the data source, set the Connected property of the TFDConnection component to true. You can set the same properties from code:
FDConnection1->ConnectionDefName = "CData Sage Intacct ODBC Source";
FDConnection1->Connected = true;
To connect the TFDQuery component to Sage Intacct のデータ, set the Connection property of the component. When a TFDQuery component is added at design time, its Connection property is automatically set to point to a TFDConnection on the form, as in the application above.
Create Parameterized Queries
To create a parameterized query, use the following syntax below:
FDQuery1->SQL->Text = "select * from Customer where customerid = :CustomerId";
FDQuery1->ParamByName("customerid")->AsString = "12345";
query->Open();
The example above binds a string-type input parameter by name and then opens the dataset that results.
Prepare the Statement
Preparing statements is costly in system resources and time. The connection must be active and open while a statement is prepared. By default, FireDAC prepares the query to avoid recompiling the same query over and over. To disable statement preparation, set ResourceOptions.DirectExecute to True; for example, when you need to execute a query only once.
Execute a Query
To execute a query that returns a result set, such as a select query, use the Open method. The Open method executes the query, returns the result set, and opens it. The Open method will return an error if the query does not produce a result set.
FDQuery1->SQL->Text := "select * from Customer where customerid = :CustomerId";
FDQuery1.ParamByName("customerid")->AsString = "12345";
FDQuery1->Open();
To execute a query that does not return a result set, use the ExecSQL method. The ExecSQL method will return an error if the query returns a result set. To retrieve the count of affected rows use the TFD.RowsAffected property.
FDQ.SQL.Text := "delete from Customer where Id = :Id";
FDQuery1->Params->Items[0]->AsString = "x12345";
FDQuery1->ExecSQL();
AnsiString i = FDQuery1->RowsAffected;
