Using AW_EXPR in OLAP_TABLE

Question

Hi all,
What datatypes are supported by AW_EXPR ? Were can I find more info on AW_EXPR ?
These questions arise after having track down an error using the OLAP_TABLE function. I was trying to fetch the combined value for the boolean OLAP NASkip and NASkip2 settings using the following select statement :
select * from table(olap_table('', '', '', 'measure NASettings from aw_expr NASkip and NASkip2'))
Clearly AW_EXPR is needed here because I fetch an expression of existing OLAP objects and not an existing OLAP object itself. However, this statement fails.
For your info, both following statements run correctly :
select * from table(olap_table('', '', '', 'measure NASettings from aw_expr Convert(NASkip and NASkip2, Integer)'))
select * from table(olap_table('', '', '', 'measure NASettings from aw_expr Convert(NASkip and NASkip2, Text)'))
Also this is possible :
select * from table(olap_table('', '', '', 'measure NASkip from NASkip, measure NASkip2 from NASkip2'))
but then the AND has still to be executed ...
Thanks in advance for giving me some info on the possibilities/limitations of AW_EXPR.

Answer 1

The original error message is
select * from table(olap_table('', '', '', 'measure NASettings from aw_expr NASkip and NASkip2'))
ERROR at line 1:
ORA-29913: error in executing ODCITABLESTART callout
ORA-00600: internal error code, arguments: [17183], [0xA1A0B70], [], [], [], [], [], []
ORA-34100: Values of type NUMBER are expected.
Adding parenthesis doesn't change a thing. The error remains the same.
