I found the git IGNITE-3394 entry on the web. However, the "type" looks to
be a Java class and doesn't really give me anything to go on for a CLOB vs a
VARCHAR2. However, I did create a Transformer and plugged it in (or so I
thought) to try and see what came through for each field during a debugging
session. However, my Transformer is never being called.
This is what I have.
*--------------------------------
new JdbcTypesTransformer
--------------------------------*
public class JdbcTypesClobTransformer extends JdbcTypesDefaultTransformer {
public static final JdbcTypesClobTransformer INSTANCE = new
JdbcTypesClobTransformer();
private JdbcTypesClobTransformer() { }
@Override
public Object getColumnValue(ResultSet rs, int colIdx, Class<?> type)
throws SQLException {
System.out.println("************** INSIDE
JdbcTypesClobTransformer");
Object val = rs.getObject(colIdx);
if (val == null)
return null;
// code to check for CLOB goes here
return super.getColumnValue(rs, colIdx, type);
}
}
*--------------------------------------------------------------
changes to HistoryResultsCacheConfig cache() method
--------------------------------------------------------------*
// existing method call
storeFactory.setTypes(jdbcTypes.toArray(new
JdbcType[jdbcTypes.size()]));
// new method call
storeFactory.setTransformer(JdbcTypesClobTransformer.INSTANCE);
