I have a simple inventory list program. It is so simple it uses the cycle.
I am trying to modernize it and I am running into difficulties on
selecting (and sorting) records in CL using OPNQRYF. I am not opposed to
using SQL, but I have only played around with it a little bit and am not
very familiar with it.
Our product is steel pipe and we need to select on 4 fields. Outside
diameter (OD) wall, feet and inches. If I try to select a range from 2
feet 1 inch to 5 feet 11 inches, %range will grab all feet that are
between 2 and 5, and then all inches that are between 1 and 11. This is
not what I want.
I need to select lengths by treating feet and inches as one field. I
can create a logical file view with dds and concatenate the two fields
into one. But I cannot do it for od and wall because they have decimals.
I was planning on digging into the arcane rites and rituals of MAPFLD,
as well as seeing if Query Manager could create valid SQL statements for
me. (I"ve used Query Manger to create SQL statements in the past.) But
I thought I'd ask here first if there was a better way. I know I could
probably do the select in RPG, but I'm not sure about the sort part.
Plus I'm used to the old ways of getting the file the way you want it,
