SELECTRULE Subcommand (CSSELECT command)
SELECTRULE
generates a text file containing a rule that describes characteristics
of selected units.
- The selection rule is not generated by default.
-
OUTFILE
specifies the name of the file. If the file exists, it is overwritten without warning. - The selection rule is written in generic notation,
for example—
(a EQ 1) AND (b EQ 2)’
. You can transform the selection rule into SQL code or command syntax that can be used to extract a subframe for the next stage of a multistage extraction.
