Re: [EXTERNAL] records between two dates

Qry/400 and View show the same result as I mentioned earlier.( i mean when
i use the view in WRKQRY both select count(*) from lib1/v1 and WRKQRY's
report count is exactly same when i used this view in the WRKQRY and used
that RANGE (in test) for date 20210601 20210607)

But that record count in view and file differ this is i am not able to
figure out so far why the view which is based on the same file show
different record count from its based file for same selection criteria (i
mean for these dates), i tried both ways by removing single quotes and
including single quotes from the dates but in both cases record count in
the view was too much than the file for the same dates selection criteria)
all these 4 fields (fiield4,field5,field6,field7) are pure decimal only
(with packed data type and 0 decimal position)
also i already shared the structure of this file ( like how is the sequence
and their data types and length of all the fields in this file) i am not
sure what else is required to explain it in more detail ?

I also compared record by record and then i found that view has too many
additional records compared to the file apart from the matching records(
the records which match from this file in the view are exactly same but
view has many additional records too which were not found in the file for
the same dates (between) selection criteria)

also i checked that view is based on physical file only and in the same
library only.


Thanks.

Since you are getting different numbers you've got to do some debugging.

Maybe qry400 and sql handle bad data differently? Is all data in the 4
fields definitely valid decimal data?

You may also want to compare record by record the results of using the
view vs using the file.

You are sure that the view is built over the correct physical file in
the right library ? And it's not a logical?

And to repeat what others have said, without seeing actual code and
results, we're kind of stuck.

Hi,

Ok, so if the record counts for (1. and 2. SQL Queries ( on file1) was

too

less than compared to record count for (3. and 4. (SQL queries for

record

count for view (V1) )
then is it fine or acceptable or is there any probability of Typos - bad
field names, transposed characters here which might cause this imbalance
in terms of record counts here?

I mean to ask, is it OK to say that a view can have more records

compared

to the file on which it is based ?

or conceptually it's wrong here? ( considering my SQL queries and Views

for

which I shared Queries in my last posts ( 1.,2.,3.,4.)

if it's right then I have equal records for my view and in the WRKQRY but
if it's wrong then my view and WRKQRY has too many more records compared

to

the SQL queries ( on file1 SQL Queries 1. and 2.)


Thanks.

Proof of concept? … everything you have written should work – so if it
isn’t working then you have some bad code somewhere.



SQL works fine. QRY works fine.

Hi,



But how would it make a difference? I just want to make a proof of

concept

for this. How does it matter whether the field name is field1 or 'x','y'
'z' etc.



Thanks

You need to share the actual code and the actual file layouts.

Hi,



I just changed field names and file name and library name here but on

the

actual file and field names when I replace these SQL queries with the
actual file and field names then getting the same kind of results as I
shared here.





Thanks.
