TAG Argument
Use the TAG
argument in a SELECT
command to
create an additional output field named TAG
that
will be available in any segment generated by the command. This allows
for the output from multiple SELECT
commands
to be correlated back to the originating command.
In the following example, the returned records are marked with
a
TAG
value of TODAY
or TOMORROW
,
depending from which LIST
statement they come.OUTPUT ADCOM FIELDS(TAG,ADID,ADFROM,ADSTAT)
SELECT ADCOM ADID(ABC123) VALID(=) TAG(TODAY)
SELECT ADCOM ADID(ABC123) VALID(+1) TAG(TOMORROW)
Note: Any
SELECT
statements generated
from a LIST
statement using OPTIONS
SELECT(Y)
is automatically passed the same TAG
argument.
