Apptivity : What causes RS MetaData mismatch warnings
This knowledgebase discusses the cause and meaning of warnings
of the form:
Warning: RS MetaData mismatch for <datasource> column <column>
RS MetaData mismatch warnings indicate that the column
descriptions being reported by the database driver at
runtime for the columns specified are different than those
reported by the driver that was used during development.
Warnings may occur if the driver used during development
is different than the one used at runtime, which is
commonly the case.
In most cases if the types reported by the two different
drivers are similar enough, then the application will
function properly even though the data types are different.
These warnings are known to occur if a NUMBER column is
defined an Oracle table with no precision specified. There
may be other conditions under which the warnings occur
of which we are not aware.
The warnings are just warnings and will not necessarily
impact the runtime behavior of the application. However,
if there are application failures which may be traced to
mis-interpretation of data these warnings are a reminder
of one thing to investigate to remove the failures.
