Hi,

So if 'creating and using the view in WRKQRY ' is the only way to prove
that both SQL query and WRKQRY match in terms of the end result data set
then what are the steps which need to be followed to do so specifically for
this SQL Query ( ' SELECT * FROM LIB1/file1 where ((field1*
1000000) + ( field2*10000) + (field3*100) + field4) between '20210601'
and '20210607' ) when trying to build that equivalent WRKQRY ?

Thanks.

But what if this needs to be proved using WRKQRY only that SQL query
matches with WRKQRY in terms of result then What would be the
structure of that WRKQRY?

Thanks

the

If I need to verify the records are certain using this manner how
can I cross verify it through WRKQRY:-

I mean, if my sql query is like this :- ' SELECT * FROM LIB1/file1

where

((field1* 1000000) + ( field2*10000) + (field3*100) + field4)
between '20210601' and '20210607'

Then just to cross verify whether this SQL query shows the correct
record set then what is the counter WRKQRY I could prepare to be
sure whether both SQL and WRKQRY show the same result set here?

Thanks.

Subject: [EXTERNAL] records between two dates

Hi,

How to filter records from a date field if it's split in CC YY MM
DD ( Each field here with 2 length and decimal data type) using
SQL query

from

a file?

i mean date field is like in file1 like below:-

fld1 fld2 fld3
fld4

So from this type of split fields how can we filter records for a

specific
