Re: SQL insert using select

Ok the manager wants it like this :

Pgm reads a file containing the names of other files and the field
name corresponding to the client number.

Pgm must copy from the file in *CURLIB to the file of the same name in
LIBx ( parameter), replacing value of "field name corresponding to the
client number" with client number(parameter).

Manager wants to avoid temporary intermediate file. A DS is not
possible as the file name is only known at run time.

I expect it is technically possible to construct the sql needed to do this :
1. Get name of file to copy
2. Get field names of file to copy.
3. Build SQL insert :

Insert into "filename"
select "clientnumber", field1, field2, etc,etc from LIBx/filename

Don't know if it's really worth the hassle to avoid the intermediate
file, but it looks like it might be fun for me!
How would I get the the list of file fields? (I only know dspffd)

Well if you prompt the select in STRSQL

You can easily prompt the field selection, then it's just a matter of
putting a 1 in 300 fields...bingo you have your fields :) Or copy the
names from the 5250 screen to a text editor...

If you happen to have SQuirreL SQL Client, I think you could drag and
drop the field names...

There's only about 300 field names in the files!
But Aaron has given me an idea :
create table temp as select client n etc
update temp set client x etc

then insert

have to specify the other columns on the select

insert into myfile
select 'x', fld2, fld3,fld4, <...>
from myotherfile

Hi,
I need to do this on a bunch of files :

insert into myfile
select *from myotherfile where clientnumber = 'n'

problem is, I want to set the clientnumber that is written to myfile to 'x'.

Possible?
