SQL transformation field mapping

SQL transformation field mapping

Configure field mapping in an SQL transformation to define how to use data from the upstream transformation in a stored procedure or function. You do not configure field mapping when the transformation processes a query.
Configure field mapping on the
Field Mapping
tab of the
Properties
panel.
You can configure the following field mapping options:
Field Map Options
Method of mapping fields to the SQL transformation. Select one of the following options:
  • Manual. Manually link incoming fields to the store procedure or function's input fields. Removes links for automatically mapped fields.
  • Automatic. Automatically link fields with the same name. Use when all of the fields that you want to link share the same name. You cannot manually link fields with this option.
  • Completely Parameterized. Use a parameter to represent the field mapping. In the task, you can configure all field mappings.
  • Partially Parameterized. Configure links in the mapping that you want to enforce and use a parameter to allow other fields to be mapped in the mapping task. Or, use a parameter to configure links in the mapping, and allow all fields and links to display in the task for configuration.
    To see more information on field mapping parameters, see
    Mappings
    .
Show Fields
Controls the fields that appear in the
Incoming Fields
list. Show all fields, unmapped fields, or mapped fields.
Automap
Links fields with matching names. Allows you to link matching fields, and then manually configure other field mappings.
You can map fields in the following ways:
  • Exact Field Name.
    Data Integration
    matches fields of the same name.
  • Smart Map.
    Data Integration
    matches fields with similar names. For example, if you have an incoming field
    Cust_Name
    and a target field
    Customer_Name
    ,
    Data Integration
    automatically links the
    Cust_Name
    field with the
    Customer_Name
    field.
You can use both Exact Field Name and Smart Map in the same field mapping. For example, use Exact Field Name to match fields with the same name and then use Smart Map to map fields with similar names.
You can undo all automapped field mappings by clicking
Automap
Undo Automap
. To unmap a single field, select the field to unmap and click
Actions
Unmap
.
Data Integration
highlights newly mapped fields. For example, when you use Exact Field Name,
Data Integration
highlights the mapped fields. If you then use Smart Map,
Data Integration
only highlights the fields mapped using Smart Map.
Action menu
Additional field link options. Provides the following options:
  • Map selected. Links the selected incoming field with the selected stored procedure or function input field.
  • Unmap selected. Clears the link for the selected field.
  • Clear all. Clears all field mappings.
Show
Determines how field names appear in the
Stored Procedure Input Fields
list. Use technical field names or labels.
