Your name               : Diab Jerius

Category                : unknown
Severity                : non-critical

Summary: obscure error when misusing table name as an attribute

System Configuration
--------------------
  Operating System   : Solaris 2.6

  PostgreSQL version : 6.4.2

  Compiler used      : Sunpro cc 4.2

Hardware:
---------
SunOS fondue 5.6 Generic_105181-12 sun4m sparc SUNW,SPARCstation-20


Versions of other tools:
------------------------
flex 2.5.4


--------------------------------------------------------------------------

Problem Description:
--------------------
I get a very obscure error message when I mistakenly use
a table name as an attribute and compare it to
an IN clause

--------------------------------------------------------------------------

Test Case:
----------
xrcf_tc_log is a table; there is no attribute in xrcf_tc_log
named xrcf_tc_log

spectral=> select xtc_testid from xrcf_tc_log where xrcf_tc_log not in ( select trwid from as_run_cmdb );
NOTICE:  unknown node tag 704 in fireRIRonSubselect()
NOTICE:  Node is: { IDENT "xrcf_tc_log" }
ERROR:  ExecEvalExpr: unknown expression type 704


Shouldn't it say something like "Yo Dude! no such attribute"?

--------------------------------------------------------------------------

Solution:
---------


--------------------------------------------------------------------------

Added to TODO list.  I like your error message much better.
