TDBM uses Doctrine DBAL under the hood to access your database. Doctrine DBAL provides a solid abstraction layer allowing TDBM to be compatible with many databases out of the box.
TDBM is tested with these databases:
TDBM is not compatible with Sqlite (because the database does not support foreign keys properly)
Oracle 11g does not have a notion of JSON column and DBAL casts those columns in CLOB. But CLOB columns have an issue (they cannot be part of a DISTINCT query) that is used by TDBM. As a result, any request on a table containing a JSON column will fail.
Due to a limitation in the way OCI8 driver works, the Oracle database cannot accept streams in BLOB columns (it only accepts strings). But TDBM is exclusively using streams for BLOB columns. As a result, TDBM does not support any kind of BLOB column in Oracle.
