Unknown column 'a' in 'field list'
==================================

The field might not have been created yet: do a 
`Database compare <https://docs.typo3.org/permalink/t3coreapi:database-upgrade>`_.

This error might occur if a model contains a field that does not exist
in the corresponding database table. In this case you should add the
field to the table in ext_tables.sql.

Table 'db.tx_myextension_domain_model_mymodel' doesn't exist
============================================================

*   The table might not have been created yet: do a 
    `Database compare <https://docs.typo3.org/permalink/t3coreapi:database-upgrade>`_.
