Outreach.io ODBC Driver
Outreach.io ODBC ドライバーは、ODBC 接続をサポートする任意のアプリケーションからリアルタイムなOutreach.io アカウントデータに直接接続できるパワフルなツールです。標準のODBC ドライバーインタフェースを使用して、データベースのようにOutreach.io データにアクセスし、読み、書き、更新を実行できます。
The CData ODBC Driver for Outreach.io makes it easy to integrate connectivity to live Outreach.io 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 Outreach.io 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.
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.
OAuth を使用してOutreach で認証する必要があります。InitiateOAuth 接続プロパティを"GETANDREFRESH" に設定します。詳しくは、ヘルプドキュメントの「OAuth 認証の使用」セクションを参照してください。
You can then follow the steps below to use the Data Explorer to create a FireDAC connection to Outreach.io.
Follow the procedure below to start querying Outreach.io 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:
Drop a TFDQuery component onto the form and set the properties below:
SQL: Click the button in the SQL property and enter a query. For example:
SELECT Name, NumberOfEmployees FROM Accounts WHERE Industry = 'Textiles'
Drop a TDataSource component onto the form and set the following property:
Drop a TDBGrid control onto the form and set the following property:
You can use the TFDConnection and TFQuery components to execute queries to Outreach.io のデータ. This section provides outreachspecific examples of executing queries with the TFQuery component.
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 Outreach.io ODBC Source";
FDConnection1->Connected = true;
To connect the TFDQuery component to Outreach.io 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.
To create a parameterized query, use the following syntax below:
FDQuery1->SQL->Text = "select * from Accounts where industry = :Industry";
FDQuery1->ParamByName("industry")->AsString = "Textiles";
query->Open();
The example above binds a string-type input parameter by name and then opens the dataset that results.
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.
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 Accounts where industry = :Industry";
FDQuery1.ParamByName("industry")->AsString = "Textiles";
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 Accounts where Id = :Id";
FDQuery1->Params->Items[0]->AsString = "x12345";
FDQuery1->ExecSQL();
AnsiString i = FDQuery1->RowsAffected;
