View Developer Edit
 [2001-01-26 12:26 UTC] mnewnham at adacorp dot com 
Platform: HPUX 10.20
Configuration:  PHP4.0.1pl2 --with-iodbc --without-mysql  --with-pdflib=/usr/local --without-gd 
--with-apache=../apache_1.3.14      
Using Openlink MT ODBC driver against a PROGRESS database.

Any version of PHP after 4.0.1pl2 cannot parse queries with a JOIN statement in it. Versions upto and including above work ok.

The log file from the Openlink Server shows this from a sample (good) query:

generic_pro83b: SCR_AnalyseSQL failed: SELECT * FROM VIRTUAL_LAYERS INNER JOIN LAYER_INFORMATION ON LAYER_INFORMATION.LAYER1_DESCRIPTION=VIRTUAL_LAYERS.LAYER1_DESCRIPTION  
generic_pro83b: parse error 
generic_pro83b: SELECT * FROM VIRTUAL_LAYERS INNER JOIN^

Configuration above should show PHP4.0.2 not 4.0.1pl2

problem still exists in PHP 404 sp1

have you tried updating to the latest OpenLink libraries?  They have supposedly been better enhanced and unified with PHP.

According to openlink, the issue is caused by the dynamic cursors now used in the php odbc functions. 

remarking out the #define HAVE_SQL_EXTENDED_FETCH 1 entry in the iodbc section provides a temporary relief from the problem.

this issue is specific to the interaction of the Progress database and the OpenLink Agent-based cursor library

once scrollable cursors are not used this is not a problem

moving this to analyzed as hopefully once I work out this cursors patch it will be gone too!

Patch submitted.... sort of.  Go CVS go!  Connect and finish the commit!
