Make Subrecord stage in DataStage: Examples


This section gives examples of input and output data from a Make Subrecord stage.

In this example, the Make Subrecord stage extracts data from four input columns, three of which carry vectors. The data is output in two columns, one carrying the vectors in a subrecord, and the nonvector column that is passed through the stage. The example assumes that the job is running sequentially. The following table shows column definitions for the input data set:
Table 1. Column definitions
Column name SQL type
key Char
acol Integer
bcol Char
ccol Char
The following table shows the rows from the input data set (superscripts represents the vector index):
Table 2. Input data set
  Key acol bcol ccol

row B 2206142213 Robin0Dally1Rob2RD3 G0A1

row I 300172823 Kath0Cath1Catherine2Katy3 0H1
row J 500172023 upert0Rupe1Woopert2puss3 B0C1
The stage outputs the subrecord that it builds from the input data in a single column called parent. The column that is called key will be output separately. The output column definitions are as follows:
Table 3. Output column definitions
Column name SQL type
key Char
parent Char

The output data set will be:
