Member Function Documentation

GetInfo()

unique_ptr< CreateInfo > duckdb::TypeCatalogEntry::GetInfo ( ) const

overridevirtual

Reimplemented from duckdb::CatalogEntry.

                                                       {
    auto result = make_uniq<CreateTypeInfo>();

    result->dependencies = dependencies;
    result->comment = comment;
    result->tags = tags;
    result->bind_function = bind_function;
    return std::move(result);
}

Copy()

unique_ptr< CatalogEntry > duckdb::TypeCatalogEntry::Copy ( ClientContext &  context ) const

overridevirtual

Reimplemented from duckdb::CatalogEntry.

                                                                            {

    auto &cast_info = info_copy->Cast<CreateTypeInfo>();
    auto result = make_uniq<TypeCatalogEntry>(catalog, schema, cast_info);
    return std::move(result);
}

ToSQL()

string duckdb::TypeCatalogEntry::ToSQL ( ) const

overridevirtual

Convert the catalog entry to a SQL string that can be used to re-construct the catalog entry.

Reimplemented from duckdb::CatalogEntry.

                                     {
    duckdb::stringstream ss;
    ss << "CREATE TYPE ";
    ss << KeywordHelper::WriteOptionallyQuoted(name);
    ss << " AS ";
 
    auto user_type_copy = user_type;
 
    // Strip off the potential alias so ToString doesn't just output the alias
    user_type_copy.SetAlias("");
    D_ASSERT(user_type_copy.GetAlias().empty());
 
    ss << user_type_copy.ToString();
    ss << ";";
    return ss.str();
}
