ls -d -1 *.h* | grep -v odb | tr '\n' ' '| xargs odb -I./ --ixx-suffix .ipp -d sqlite --generate-schema --at-once   --std c++11 --generate-query --generate-session --input-name contact --show-sloc

ls -d -1 *.h* | grep -v odb | tr '\n' ' '| xargs odb -I./ --ixx-suffix .ipp -d sqlite --generate-schema --at-once   --std c++11 --generate-query --generate-session --input-name phonenumber --show-sloc

By the commands above, the ODB compiler would generate contact-odb.cxx and phonenumber-odb.cxx, both of cxx files have static create_schema() function.

 namespace odb
  static bool
  create_schema (database& db, unsigned short pass, bool drop)

    if (drop)

When calling odb::schema_catalog::create_schema(*db);it always debug into call create_schema() in contact-odb.cxx.
How can I call create_schema() in contact-odb.cxx for contact.db and create_schema in phonenumber-odb.cxx for phonenumber.db?

Hope to hear from you very soon! Thank you!
