LOAD DATA INFILE into multiple tables with one statement

I have a .csv file I need to have loaded into a mySql database version 4.0.18.

The database is rather new, and empty of data as of right now.

I am interested in using the LOAD DATA INFILE command to import the data from the csv file into the database tables.

In the .csv file I have the following information:
Column
Hotel_Name      - Hotel Table
CheckIn_Date      - Reservation Table
CheckOut_Date      - Reservation Table
Room_Type      - Room Table
Room_Rate      - Room Table
Sabre_Code      - Reservation Table
Reservation_Number      - Reservation Table
Cancellation_Number      - Cancellation Table

There are hundreds of rows in the csv file, so it is not feasable to do an insert statement to put each record into the database.

I can't seem to find the correct syntax to insert data into multiple tables from one LOAD DATA INFILE command.  Is this possible?

I have tried to using this, but I get a Syntax error.

LOAD DATA INFILE 'c:/hoteldata.csv' REPLACE
   INTO TABLE hotel
   FIELDS TERMINATED BY ','
        WHEN hotel_name != ''
   ( hotel_name )
   INTO TABLE reservation
   FIELDS TERMINATED BY ','
        WHEN checkin_date != ''
   (  checkin_date )
   INTO TABLE reservation
   FIELDS TERMINATED BY ','
        WHEN checkout_date != ''
   (  checkout_date )
   INTO TABLE room
   FIELDS TERMINATED BY ','
        WHEN room_type != ' '
   (  room_type )
   INTO TABLE room
   FIELDS TERMINATED BY ','
        WHEN room_rate != ' '
   (  room_rate )
   INTO TABLE reservation
   FIELDS TERMINATED BY ','
        WHEN sabre_code != ' '
   (  sabre_code )
   INTO TABLE reservation
   FIELDS TERMINATED BY ','
        WHEN reservation_id != ' '
   (  reservation_id );

I have also tried this, but same result Syntax error:
LOAD DATA INFILE 'c:/hoteldata.csv' INTO TABLE hotel FIELDS TERMINATED BY ','
     TEXT_FIELDS (text_field1, text_field2, text_field3, text_field4, text_field5, text_field6, text_field7)
     SET hotel_name=CONCAT(text_field1)
     IGNORE (text_field2, text_field3, text_field4, text_field5, text_field6, text_field7);

Any ideas on how to handle inserting data into multiple tables from one file, with one statement?
Or am I going to have to do this with a couple of LOAD DATA INFILE statements?

Thanks,

You can't load data into multiple tables from one file with one statement using normal MySql tools.  

First load the data into a single table, then move it around to the needed tables using SQL statements.  If you need something more complex some programming will be required.

Oracle can do what you want, but not MySql.  You can use update with multiple tables with MySql 4 or better once your table is imported.

Sorry for the delay, been super busy writing all this SQL code to handle this functionality.

Ended up creating a temp table to load the data into, then used Insert/Update statements to update the other tables.

Thanks for the help.
