How to show warning messages for LOAD DATA INFILE

Ever wondered what the warning messages were when you did a load data infile in MySQL? Well in MySQL 4.1.0 and greater you can by issuing a "SHOW WARNINGS" command at the mysql console- e.g.

mydb1707>load data infile '/tmp/people.txt'
-> into table webapps.merchants
-> fields terminated by '\t'
-> lines terminated by '\n'
-> ignore 1 lines;

Query OK, 103 rows affected, 14 warnings (0.06 sec)
Records: 103 Deleted: 0 Skipped: 0 Warnings: 14

mydb1707>show warnings;
