## Unknown column 'a' in 'field list' {#unknown-column-a-in-field-list}

The field might not have been created yet: do a
[Database compare](https://docs.typo3.org/m/typo3/reference-coreapi/main/en-us/ApiOverview/Database/DatabaseUpgrade/Index.html#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 {#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/m/typo3/reference-coreapi/main/en-us/ApiOverview/Database/DatabaseUpgrade/Index.html#database-upgrade).
-   The TCA for the model is missing.
-   You intend to use a different table with your model.
    See [Connecting the model to the database](https://docs.typo3.org/m/typo3/reference-coreapi/main/en-us/ExtensionArchitecture/Extbase/Domain/Model.html#extbase-persistence-database-connection)
