Showcase Query 6.51 and V5R4

Hoping to find someone out there that may have run into this and
resolved it. We are running Showcase 6.51 on two boxes against two
completely different set of databases. We upgraded on of them about a
year ago to V5R4 and even though SPSS told us that 6.51 was not
supported on that box, there was apparently a patch that got things
working. So right now, that box is still running 6.51 on V5R4. (I
know, it's an ancient version of Showcase but it is set to retire in
less than a year now). So we recently upgraded the other box to V5R4,
with my huge disclaimer that Showcase albeit running on the other, is
NOT supported. Lo and behold, it tipped over "mostly". Calls to
SPSS/IBM are just met with "you have to upgrade" and if there was any
patch that fixed this a year ago, I can't find any record of it.



So we are stuck. The error message we receive upon running a query is
"SENSITIVE cursor XX cannot be defined for specified SELECT statement"
(where XX changes all the time). I have further narrowed this down to
the error only comes up with a query in it that has a SUM function in it
(probably other functions as well, just know this one for sure).



Does anyone have any input on this or a workaround that we may consider?
I've Googled everything and I'm just not finding any references to
solutions. Upgrading is not really an option because they don't want to
spend any money on it. My warning was not heeded and now they don't
really care, just fix it.



Thanks in advance...
