Alan,
You mean like this?

CREATE TABLE QTEMP/FILE01 (MYCHAR CHAR (10 ) NOT NULL WITH DEFAULT,

  MYNBR DEC (5 , 2) NOT NULL WITH DEFAULT)
  Table FILE01 created in QTEMP.

CREATE TABLE QTEMP/FILE02 (MYCHAR CHAR ( 10) NOT NULL WITH DEFAULT,

  MYNBR DEC ( 5, 2) NOT NULL WITH DEFAULT)
  Table FILE02 created in QTEMP.

INSERT INTO QTEMP/FILE01 VALUES('A', 1.2)

  1 rows inserted in FILE01 in QTEMP.

INSERT INTO QTEMP/FILE02 VALUES('B', 2.3)

  1 rows inserted in FILE02 in QTEMP.

CREATE VIEW QTEMP/FILE0102 AS(

  SELECT * FROM FILE01
  UNION
  SELECT * FROM FILE02
  )
  View FILE0102 created in QTEMP.

SELECT * FROM FILE0102


....+....1....+...
MYCHAR       MYNBR
A             1.20
B             2.30

RE: imbedded sql sytax question







The "problem" (please take note of quotes) with this answer is that there
is an implicit assumption that there's a record in file1 that corresponds
to a record in file2 and vice-versa.
One of the good things that most mainframes had (IBM, UNIVAC, BURROUGHS,
UNISYS, ICL etc) was that there was a way to pseudo concatenate like

files

together (through JCL, WFL etc) so that 2 separate, but like files,

looked

like it was in fact one larger file.
Is there a way of doing this in SQL?

Easy, suppose your select statement looks like:

select a.field1, a.field2, b.field3, b.field4, date(b.charDate) as

TheDate

from thisFile A join ThatFile B
on a.field1 = b.field26
where a.field13>13000

Now take that same select statement and prefix it with one line
Create view mylib/myfile as (
select a.field1, a.field2, b.field3, b.field4, date(b.charDate) as

TheDate

from thisFile A join ThatFile B
on a.field1 = b.field26
where a.field13>13000)

Ok,

Can you give me an example of the CREATE VIEW?

Hopefully not-hosed...

Do you do this kind of join a lot?  If so, then, outside of your

program,


do a
CREATE VIEW
and do the join in there.  That will then have all the fields you might
want in your datastructure to fetch into.  Otherwise, you're hosed.

imbedded sql sytax question






Hi All,



I have a select statement as follows:



Select  * from File1 where phonenumber = '2015551212';



This works great, but now I have another file (File2 or argument sake)
that
contains additional phone numbers. File1 and File2 can be joined by
clientnumber.



My code is as follows





exec sql set option datfmt=*usa;

exec sql prepare s2 from :dynstm;

exec sql declare c2 cursor for s2;

exec sql open c2;

exec sql fetch c2 into :thefileds;

dow sqlcod = 0;





Is there a way for me to join these 2 files together (File1 & File2)

and

still be able to use the "thefileds" on my fetch.





Hope this makes some kind of sense.



Tim
