sddsexpand
reads data pages from an SDDS file and writes a new
SDDS file containing a separate data page for every row in the input
file. All column definitions from the input file are turned into
parameter definitions in the output file. In addition all parameter
definitions from the input file are copied to the output file. Each
output data page contains the values of the columns from a single row
of the input file, along with the values of the parameters from the
same page. The output file contains no column or array definitions.
sddsexpand
is essentially the inverse of sddscollapse
(except that the column data thrown out in collapsing a file is not
recoverable).
