WARNING CODE :1265 in Mysql

Hi All.

I originally had a VARCHAR column and I want  to convert it to INT , when i run  statement

USE plan; CREATE TABLE tbl_budgetplan_new LIKE tbl_budgetplan;
ALTER TABLE tbl_budgetplan RENAME  tbl_budgetplan_old;
INSERT INTO tbl_budgetplan_new SELECT * FROM tbl_budgetplan_old;
ALTER TABLE tbl_budgetplan_new MODIFY COLUMN PersonId INT NOT NULL;
ALTER TABLE tbl_budgetplan_new RENAME tbl_budgetplan;

6 queries executed , 6 success , 0 error , 1 warning

6036 row(s) affected , 1718 warnings

warning code (1265): Data truncated for column 'PersonId' at row 1

What can I do about this ?

Thanks.
