INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10

A syntax error can occur when a select query is ran against a 
synonym in server_b that points to a view on server_a, or when a 
query is ran on server_b against a view on server_a, in both 
cases these database server instances are in the same host. 
 
Syntax error only occurs if the view is useing ANSI join, for 
example: 
 
create view tstvw 
    ( 
    fld1, 
    fld4, 
    fld2 
    ) 
as  select  a.fld1, 
            b.fld4, 
            b.fld2 
      from  tab1 a 
            left outer join tab2 b  on  a.fld1 = b.fld1 
            left outer join tab3 c  on  a.fld3 = c.fld3;

* PROBLEM DESCRIPTION:                                         * 
* A query involving a remote view may return syntax error      * 
* under the following conditions:                              * 
*   - the remote view is defined in ANSI OUTER JOIN syntax,    * 
* e.g. "create view v1(a,b) as select tab1.col1, tab2.col2     * 
* from tab1 left outer join tab2 on ...."                      * 
*   - the main query has a predicate in the where clause on a  * 
* view column that corresponds to a subservient table in the   * 
* view definition, and this predicate excludes NULL values,    * 
* e.g. select ... from remotedb@remoteserver:v1 where v1.b =   * 
* <constant>                                                   * 
**************************************************************** 
* RECOMMENDATION:                                              * 
* Update to IBM Informix Server 12.10.xC6                      *

A possible workaround is to replace the ANSI syntax with 
Informix syntax: 
 
create view tstvw 
    ( 
    fld1, 
    fld4, 
    fld2 
    ) 
as  select  a.fld1, 
            b.fld4, 
            b.fld2 
      from  tab1 a, outer tab2 b, outer tab3 c 
     where  a.fld1 = b.fld1 
       and  a.fld3 = c.fld3;
