Split Subrecord stage in DataStage

Split Subrecord stage

The Split Subrecord stage separates an input subrecord field into a set of top-level vector columns.

The Split Subrecord stage can have a single input link and a single output link.

The stage creates one new vector column for each element of the original subrecord. That is, each top-level vector column that is created has the same number of elements as the subrecord from which it was created. The stage outputs columns of the same name and data type as those of the columns that comprise the subrecord.

The Make Subrecord stage performs the inverse operation (see , "Make Subrecord Stage.")

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.
