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

This section gives examples of input and output data from a Split Subrecord stage to give you a better idea of how the stage works.

In this example the Split Subrecord stage extracts data from a subrecord containing three vectors. The data is output in fours column, three carrying the vectors from the subrecord, plus another column which is passed through the stage. The example assumes that the job is running sequentially. The column definitions for the input data set are as follows:
Table 1. Column definitions
Column name SQL type
key Char
parent Char

The following are the rows from the input data set (superscripts represents the vector index):

The stage outputs the data it extracts from the subrecord in three separate columns each carrying a vector. The column called key will be output separately. The output column definitions are as follows:
Table 3. Output column definitions
Column name SQL type
key Char
acol Integer
bcol Char
ccol Char

The Subrecord column property is set to 'parent' in the Properties tab.

The output data set will be (superscripts represents the vector index):
