Change the table comment after created the table is not supported now?
Like mysql : ALTER TABLE [tableName] COMMNET [comment]; 
The sql "ALTER TABLE `system`.tables UPDATE Comment='test' WHERE NAME='t1';" also not supported!!!
My version is '21.9.4.35'。
{
    auto modified_query_ast = query->clone();
    ASTSelectQuery & select_query = modified_query_ast->as<ASTSelectQuery &>();
    
    
    
    select_query.setExpression(ASTSelectQuery::Expression::SETTINGS, {});
    if (table_function_ptr)
        select_query.addTableFunction(table_function_ptr);
    else
        select_query.replaceDatabaseAndTable(database, table);
    
    
    if (!table_function_ptr)
    {
        RestoreQualifiedNamesVisitor::Data data;
        data.distributed_table = DatabaseAndTableWithAlias(*getTableExpression(query->as<ASTSelectQuery &>(), 0));
        data.remote_table.database = database;
        data.remote_table.table = table;
        data.rename = true;
        RestoreQualifiedNamesVisitor(data).visit(modified_query_ast);
    }
    return modified_query_ast;
}
