RE: how to make a key on a view? -- MIDRANGE-L

Thanks Matt, I thought I remembered creating an MS SQL view which
included an index spec.

To Vern's point about the SQL standard, I wonder:

"IF" combo of View def with Index is implemented as:
1) create the view
2) create the "appropriate index(s)"

"THEN"
where is the problem with "SQL Standards" ?

Not all databases have this limitation. You can create indexes on views in other databases (oracle and MS SQL server for instance).

Actually it is not DB2 that has this restriction = it is the SQL standard that does not allow CREATE INDEX over a view. And I'm not sure if CREATE INDEX can be done over a PF that does not have DDS source - CRTPF with RCDLEN only.

HTF.COM - when you say 'txt', are you speaking of a text file in the IFS or of a file member of type TXT - that'd have to be a source file, I think.

You can't do anything directly with SQL views or LFs over IFS files - as Gary says, you create a DDS file - and I'll add, CREATE TABLE in SQL can do the same.

I have to say, I think the terms you are using are mixed up - so please clarify whether IFS or source files or whatever you are looking at.

Thanks
Vern

You could copy/convert the .txt file to a dds file that is keyed.

i HAVE A file that is 'txt' not PF. Can I make a logical DDS LF on that?
if not, how can I make an key index on a view?
