Establishing a Connection
You can create and manage connections with the Data Explorer and the FireDAC Connection Editor wizards. See Connection Definitions for more information on creating connections from code and creating persistent, private, or temporary connections.
To make use of all the features of the component, provide the User and Password connection properties.
To connect with limited features, you can set the APIKey connection property instead. For more information, refer to our Connecting to Sendgrid guide.
Using the FireDAC Connection Editor
Complete the following steps to use the FireDAC Connection Editor to assign a SendGrid connection to a TFDConnection object:
- Open a project and drop a TFDPhysCDataSendGridDriverLink from the Tool Palette onto the Form Designer.
- Drop a TFDConnection object onto the Form Designer.
- Double-click the TFDConnection and select CDataSendGrid in the Driver Id menu.
- Define the necessary connection properties.
- To execute ad-hoc SQL statements based on this connection, enter SQL commands on the SQL Script tab.
- In the Form Designer, select the TFDConnection object and set the Connected property to true.
Using the Data Explorer
Complete the following steps to use the Data Explorer to define persistent connections that can be shared across applications and projects:
- Click View > Tool Windows > Data Explorer in RAD Studio and expand the FireDAC node.
- Right-click the CData SendGrid Data Source node and click Add New Connection.
- Enter a name for the connection. The FireDAC Connection Editor opens.
Working with Persistent Connections
The connections you define in the Data Explorer can be assigned to a TFDConnection object by specifying the connection name in the TFDConnection object's ConnectionDefName property.
Browsing Data and Metadata
The Data Explorer also provides options for browsing SendGrid objects at design time:
- Expand the CData SendGrid Data Source node in the Data Explorer to view the defined connections.
- Expand a connection node to find the database objects available for a connection.
- Drill down to a database object to find metadata such as primary keys.
- To display data, double-click a table or view or right-click and click View.
