enum ozo::errc::code

Error conditions of the library.

This useful error conditions incorporate ozo, libpq and Boost.Asio error codes.

Note

Error condition type_mismatch for custom types may occur in case of database schema update which may lead to custom type oid change. For built-in types it signals about mismatching.

Enumerator
ok	no error placeholder
connection_error	connection-related error condition, incorporates ozo, libpq and Boost.Asio connection errors
database_readonly	database in read-only state - useful to detect attempt of modify data on replica host
introspection_error	errors related to objects serialization/deserialization
type_mismatch	result type mismatch, indicates types mismatch between result of query and expected result
protocol_error	specific protocol-related errors
