In Response To: Re: RE: error 201 when using functional index (Jonathan Leffler)

Hi Jonatahn, thanks for SQLIDEBUG tip, look at what i found:

The real erorr sis 206 and ISAM 111, what says the data server cant find the table, then shows error 201, then program finish with a dbclose

This is trace with functional indexes created. After trace without functional index.

Wha't the 'end function' doing?

export SQLIDEBUG=2:something

(the something is used as a prefix to the dump file names).

Then run:

$ dbaccess dbname script

$ minimal-i4gl-program

You should have two files, both starting with 'something'.

sqliprint something_...name1...

sqliprint something_...name2...

Look to see if there's anything startlingly different between what works
(DB-Access) and what doesn't (I4GL). It may be uninformative - but since
-201 syntax error often means a broken SQL statement, you may be able to
spot what is wrong with what the I4GL sent to IDS.
