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

...
 The materialized views fetched perfectly with teiid 8.11.3, once we
migrated to 9.0.0, we start having this issue. We went back to 8.11.3 the issue is no
longer reproduced. 
There are still a few details that are missing here.  It matters how the Teiid metadata
for the Oracle materialization table is defined.  Can you provide the Teiid DDL (not the
Oracle DDL) for the Oracle source schema and how it was created (such as providing the
vdb.xml)?  Somehow you are saying that in 8.11.3 the source table is being defined in
Teiid like:

CREATE FOREIGN TABLE G1(e1 integer, e2 varchar);

But in 9.0+ as:

CREATE FOREIGN TABLE G1(e1 bigdecimal, e2 varchar);

...
 if you are saying NUMBER(10) in Oracle represents bigdecimal or long.
What is the oracle datatype expected for Integer in this case? 
There isn't one directly as Oracle does not have an integral type.  I'm saying
that with the Teiid Oracle importer and the property importer.useIntegralTypes=true
NUMBER(9) will be imported as the Teiid integer type - but it's not clear to me yet
what import mechanism you are using.

                 URL: https://issues.jboss.org/browse/TEIID-4427
             Project: Teiid
          Issue Type: Bug
          Components: Query Engine
    Affects Versions: 9.0
            Reporter: Mark Tawk
            Assignee: Steven Hawkins
            Priority: Critical
             Fix For: 9.1, 9.0.4

 After migrating to Teiid 9.0.0, we are facing issues with existing views materialized on
Oracle server.
 when fetching an Oracle materialized view that contains a column using date function like
: "Month" or "Year" or "TIMESTAMPDIFF", we are getting the
error : Expected integer, but was bigdecimal.
 If we go back to Teiid 8.11.3, the same materialized views fetch without any problem.
