RE: [EXTERNAL] records between two dates -- MIDRANGE-L

You are leaving something out of your story.
Because if the results you are reporting are correct then SQL and WRKQRY are broken.
(And that’s not likely)

Are these the real field names and file names and library names?

Hi,

I tried creating SQL query on main file file1 and view V1 on this like below:-

SQL-if my sql query is like this :- ' SELECT * FROM LIB1/file1 where
((field1* 1000000) + ( field2*10000) + (field3*100) + field4) between
'20210601' and '20210607'

View:- CREATE VIEW LIB1/V1 AS ( SELECT DIGITS(DEC(FIELD1*1000000) +
(FIELD2*10000) + (FIELD3*100) + FIELD4,8,0)) AS MYDATE , A.* FROM
LIB1/FILE1 A)

Then tried below as well after including/removing single quotes from numbers for below SQL queries ( on file1) and View Queries (V1):-

1. SELECT count(*) FROM LIB1/file1 where
((field1* 1000000) + ( field2*10000) + (field3*100) + field4) between
'20210601' and '20210607'

2. SELECT count(*) FROM LIB1/file1 where
((field1* 1000000) + ( field2*10000) + (field3*100) + field4) between
20210601 and 20210607

3. select count(*) from lib1/v1 where MYDATE between '20210601' and '20210607'

4) select count(*) from lib1/v1 where MYDATE between 20210601 and 20210607

Output :- 1. = 2. for record count.
3. = 4. for record count.

but record count 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) )

So What correction either in SQL query on file1 or in the SQL query on view V1 need to be done here or is there any correction required in both here ?

Thanks.

You are in debug and data analysis mode now.
If your view is not getting the set of data you are expecting then your view definition needs to be looked at and your data analysis assumptions need to be looked at.

Hi,

I meant after changing the date to some other date name like 'mydate':-

Select count(*) from V1 where mydate between 20210601 and 20210607’ Became equivalent to WRKQRY's report count.

... But the main file on which this view was based has too low record count compared to this view count i mean for below main SQL query:-

' SELECT * FROM LIB1/file1 where ((field1* 1000000) + ( field2*10000) + (field3*100) + field4) between '20210601' and '20210607'

It shows very few records compared to the above View (V1) Query's count.

Thanks.
