i'm counting on ResultSetMetaDataImpl to create the view and stage tables columns data types; in the case of Aggregate function COUNT, the meta is returning Integer.

Here is the code used in this concern:
....
IntegerStatementImpl stmt = (StatementImpl) conn.createStatement();
ResultSetMetaDataImpl meta = (ResultSetMetaDataImpl) stmt.getResultSet().getMetaData();
for (int j = 1; j <= meta.getColumnCount(); j++) {
	int colType = meta.getColumnType(j);
	String className = JDBCSQLTypeInfo.getJavaClassName(colType);
......
}

> 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.
