WARNING:I'm no expert with mysql, but I use it a lot.

Have you actually tried mysql app ? it's very slick and easy.

Simple one two three.. slurp the file with your commands.. then do

$handle->prepare($allyourcommands); 
$handle->execute();
#that will do it.

For example; I have a txt file with commands for creating a table and place some records:

create table usertypes (    
    usertype varchar(5) not null, 
    usertype_label varchar(25) default 'user',
    usertype_child_create  TINYINT(1) DEFAULT 0, 
    usertype_child_assign_to_file TINYINT(1) DEFAULT 0, 
    usertype_child_assign_to_dir TINYINT(1) DEFAULT 0,    
    usertype_child_share TINYINT(1) DEFAULT 0,
    usertype_child_toggle_live TINYINT(1) DEFAULT 0,
    usertype_child_delete TINYINT(1) DEFAULT 0, 
    usertype_child_admin_all TINYINT(1) DEFAULT 0,
    
    usertype_file_view_all TINYINT(1) DEFAULT 0, 
    usertype_file_download TINYINT(1) DEFAULT 0, 
    usertype_file_move TINYINT(1) DEFAULT 0, 
    usertype_file_rename TINYINT(1) DEFAULT 0, 
    
    usertype_dir_recurse TINYINT(1) DEFAULT 0, 
    usertype_dir_create TINYINT(1) DEFAULT 0, 
    usertype_dir_file_upload TINYINT(1) DEFAULT 0,
    usertype_dir_incoming_file_upload TINYINT(1) DEFAULT 1, 
    usertype_dir_rename TINYINT(1) DEFAULT 0,
    
    usertype_edit_description TINYINT(1) DEFAULT 0, 
    usertype_note TINYINT(1) DEFAULT 0, 
    usertype_scan_for_new_files TINYINT(1) DEFAULT 0, 
    usertype_usertypes_edit TINYINT(1) DEFAULT 0, 
    usertype_view_all_sessions TINYINT(1) DEFAULT 0,
    row_last_modify integer(10),    
    PRIMARY KEY (usertype)
);

INSERT INTO usertypes (
usertype, 
usertype_label,
usertype_child_create, 
usertype_child_assign_to_dir,
usertype_child_toggle_live, 
usertype_child_delete,
usertype_child_admin_all,
usertype_file_view_all,
usertype_dir_recurse,
usertype_dir_rename,
usertype_file_move
) values ('a','admin',1,1,1,1,1,1,1,1,1);

INSERT INTO usertypes (
usertype,
usertype_label,
usertype_child_create,
usertype_child_assign_to_file,
usertype_child_toggle_live,
usertype_child_delete,
usertype_file_view_all,
usertype_edit_description,
usertype_file_download,
usertype_child_admin_all,
usertype_file_rename,
usertype_dir_rename,
usertype_file_move
) values ('m','manager',1,1,1,1,1,1,1,1,1,1,1);

INSERT INTO usertypes (usertype, usertype_label, usertype_file_downloa
+d)
    values ('u','user',1);

I can just cut and paste that into the mysql prompt or feed it through the handle.
