Steven Hawkins commented on TEIID-4854:
---------------------------------------

There are 3 resolutions here:

1. document that insert/update/delete is not allowed for non-string values when the spreadsheet is in a non-english locale

2. Require that the user provides the locale as a property to the resource adapter

3. Upgrade to the v4 apis to automatically determine the locale - this is a fairly substantial undertaking

There is a related issue with date/time values.  The spreadsheet also has a timezone value that is being ignored - all values are treated as essentially timezone free and read in to the locale timezone of Teiid.

There is another related issue if the user is using custom formats - while we can obtain the pattern from the metadata, it is not an exact match for Java formatting.  So we cannot reliable perform insert/update/delete if custom formats are used.

Given all the issues and the scope of 3, it seems like the full resolution may need to be delayed.

> Cell of type timestamp is reformatted after an update. Data inserted from teiid are in format "yyyy-mm-dd hh:mm:ss[.fffffffff]", which is reformatted to "dd/mm/yyyy hh:mm:ss[.fffffffff]". Subsequent update of such row throws exception "Could not convert source column Source.smalla.timestampvalue to the expected runtime type timestamp".
