Re: SQL to transform Rows to Columns -- MIDRANGE-L

Lim,

Thanks for that. What I am having trouble understanding in this case is how were you accessing each record?

If you had records like this:
Phone Feature
5551212 SomeFeature
5551212 AnotherFeature
5551212 LastFeature

And ended up with:

Phone Min1 Min2 Min3
5551212,SomeFeature,AnotherFeature,LastFeature

Using the Min function, were you ordering the data so that Min returned the next logically ordered field? What if you had only 1 record, did you end up with blanks/nulls in Min2, Min3?

Interesting.

Pete, I ask this similar question in RPG group and somebody (Not sure who, I'm
going to lookup his name when I got a chance) came up with this sql
statement:

Please note that you will have to do 8 with statements, instead of 3. I
don't have time to re-do it using your file and fields. Basically, my
file name is rmvFect1, which contains a phone number and a feature
fields. The result of this sql make a phone number with multi
records/features (up to 3) into one record with 3 features.

with first as (select phone as phone1, Min(feature) as Min1 from rmvfect1 group by phone),
second as (select phone as phone2, Min(feature) as Min2 from rmvfect1 join first on phone1 = phone and min1 < feature group by phone), Third as (select phone as phone3, Min(feature) as Min3 from rmvfect1 join second on phone2 = phone and min2 < feature group by phone) select phone1, min1, min2, min3 from first left outer join second on phone1 = phone2 left outer join third on phone1 = phone3

After perusing the web for an hour or so looking for a technique to handle this, I haven't found a solution so perhaps some of the SQL

gurus
can lend a hand.

I have an application that has a select statement that basically

selects
9 columns of data from a single row in a table. Like this:

SELECT ASJD#, ASJAB1, ASJAB2, ASJAB3, ASJAB4, ASJAB5, ASJAB6, ASJAB7, ASJAB8 FROM MyFile

I also have two other databases that have similar data but the table structure is different. Rather than have a single record with 8

columns
of data (ASJAB1-8) it can have a recurring sequence of up to 8 rows of

data. The database can vary by customer. I can't control what

database
they use. For simplicity sake, let's say they have two fields:

ID, ASJAB
This could repeat up to 8 times. So with data in the record (again, simplified) one record in one of the databases could be like this:

1234, 'stuff here', 'more stuff here', 'any stuff here', 'my stuff here', 'other stuff here', 'could be stuff here', 'no stuff here',

'end
of stuff here'

but the other table in the other database might have data like this:

1234, 'stuff here'
1234, 'more stuff here'
1234, 'any stuff here'
1234, 'my stuff here'
1234, 'other stuff here'
1234, 'could be stuff here'
1234, 'no stuff here'
1234, 'end of stuff here'

My goal is not not write database specific code.

Just to add an additional wrinkle. The rows *may* recur up to 8 times

but can vary from 0 to 8 occurrences. The fixed record *always* has eight columns but the two column table with multiple occurrences in

the
rows can vary from 0 to 8. So, I almost think that I need a loop to loop through the results and "build" a record from that but I am out

of
gas on my SQL skills at that point.

I *want* to handle this without changing the SQL statement in the application. I would just like a view or procedure that returns a record that "looks" the same to the application. The reason is that

it
simplifies the SQL processing so I don't have to change all the SQL statements in my application with a conditional statement that says if

the table is "X" then do this. If it is "Y", then do this. If it is "Z" do it this way. A view or stored procedure that returned a similar

record keeps it simple but may be impossible?

I am on V5R3M0. I am still poking around the web but I can't seem to find anything similar.

Thanks,

Pete
