On our V5R1 machine I get the same results as you do. But if I use the system name TESTI00001, it works fine. And if I create the long-name view into a permanent library, it works. Looks like a PTF needed.

It also fails with CREATE TABLE - and short name works.

I think this is business as usual (or working as designed in IBM parlance). Files created in QTEMP are not added to the catalogue tables so there is no way to convert the long SQL name into the real system file name hence the "cannot find" error.

Why is this so?
1) Performance - QTEMP files are by their nature temporary and visible only to the job owning QTEMP so why update global reference files twice (once when created and once when QTEMP is cleared at job end)? 2) COLLECTION/SCHEMA/LIBRARY names are restricted to 10 characters so how could the catalogue tables distinguish between one job's QTEMP and another? Although the catalogue tables allow for longer schema names (and QTEMP libraries are distinguished by hidden long names) there is no external access to the QTEMP internal long names. At the least this could cause conflicts where one job creates file STUFF in QTEMP and another job tries to create a file with the same name and gets told it already exists because an entry is found in the catalogue tables. Attempts to access a QTEMP file could result in file not found errors even though a catalogue entry exists. Also potential problems with files that have the same name but different record layout. 3) Recovery - less likely to require a reclaim of the catalogue tables in the event of system failure if QTEMP stuff is not in them.

Simon Coulter.
