Promote Subrecord stage
The Promote Subrecord stage is a restructure stage. It can have a single input link and a single output link.
.
The Promote Subrecord stage promotes the columns of an input subrecord to top-level columns. The number of output columns equals the number of subrecord elements. The data types of the input subrecord columns determine those of the corresponding top-level columns.
The stage can also promote the columns in vectors of subrecords.
The Combine Records stage performs the inverse operation.
The stage editor has three tabs:
- Stage tab. This tab is always present and is used to specify general information about the stage.
- Input tab. This tab is where you specify the details about the single input set from which you are selecting records.
- Output tab. This tab is where you specify details about the processed data being output from the stage.
