SQLQuery
Use the SQLQuery when the data source resides in a MS SQL Server database. The Query components return a dataset or execute a command (such as insert or update). If the Query returns data, the dataset is created as part of the Query component. You can display the returned data by either connecting the Query GetTable method or by specifying the Query as the provider for a TableView.
The Connection String property provides access to the Microsoft Data Link Properties window. Use this series of dialogs to identify the data source and create a connection string.
When you add this component to an automation, the system places it on the Global tab of the component tray. For more information, see Adding Global Components to an Automation. This component must be global to be referenced by other automations in the project.
For more information, see General Component Properties, Methods, and Events.
