Settings
The Settings tab has the following fields:
| Field | Description |
|---|---|
| Connection | Name of the Microsoft SQL Server database connection from where information is retrieved. You can select the connection from the Connection drop-down list. |
Input Settings
The Input Settings tab has the following fields:
| Field | Description |
|---|---|
| Delete | A SQL statement used to delete the record from the table. You can construct prepared SQL queries by using substitution variables (or parameters) of the form
?<fieldname> in the delete query statement.
Each substitution variable identifies an input parameter whose mapped value is substituted into the substitution variable at runtime. Input and Output tabs are populated based on the query. End the query with semicolon (;) to fetch the metadata in the table at the bottom of the query. The following example represents a typical delete query: Delete from advisor where i_id=?i_id;For the above delete query, there is no output field and input field is generated for i_id (VARCHAR). Also, the mapped value for the field name is substituted into the substitution variable ?i_id. |
| Manually Configure Metadata | Set the
Manually Configure Metadata field to
True to fetch table metadata manually. For more information, see
Manually Configuring Metadata. |
| Fields | The grid is provided for informational purposes only. |

You can either hard code the values or map them to a field from the output of a preceding activity in the flow using the Mapper.
