--- Comment #19 from Julien Nabet <serval2412 at yahoo.fr> ---
On pc Debian x86-64 with master sources updated 2 days ago, I could open the
relationship part but I noticed this on console:
warn:legacy.osl:3698:3698:connectivity/source/commontools/dbmetadata.cxx:332:
DBG_UNHANDLED_EXCEPTION in bool dbtools::DatabaseMetaData::supportsRelations()
const
    type: com.sun.star.sdbc.SQLException
    message: supportsIntegrityEnhancementFacility: feature not implemented.
    context: N12connectivity6mysqlc17ODatabaseMetaDataE

Here is the path:
1) bool DatabaseMetaData::supportsRelations() const
https://opengrok.libreoffice.org/xref/core/connectivity/source/commontools/dbmetadata.cxx#322

2) sal_Bool SAL_CALL ODatabaseMetaData::supportsIntegrityEnhancementFacility()
https://opengrok.libreoffice.org/xref/core/mysqlc/source/mysqlc_databasemetadata.cxx#395

3) mysql-connector-cpp/driver/mysql_metadata.cpp
bool
MySQL_ConnectionMetaData::supportsIntegrityEnhancementFacility()
{
       
CPP_ENTER("MySQL_ConnectionMetaData::supportsIntegrityEnhancementFacility");
        throw
sql::MethodNotImplementedException("MySQL_ConnectionMetaData::supportsIntegrityEnhancementFacility");
        return false; // This will shut up compilers
}

I don't know if mariadb c connector implements this or not but it seems that
we'll be stuck at least until we upgrade mysql c++ connector or patch it
locally.

Lionel: I tried to search a newer mysql c++ connector on Oracle website (+ a
free account), I found 1.1.9 but https://dev.mysql.com/downloads/connector/cpp/
provides a tar with only include files.
