如何从一个mysql表复制到具有不同列类型定义的另一张表？

Question

I am trying to copy from one mysql table to another table with different column type definition... from varchar to int

I am trying to copy the column codigo which is a varchar, to codProducto in another table which is an int.

This is what I tried so far:

INSERT INTO PRODUCTOS (codProducto)
SELECT CAST(codigo as SIGNED)
FROM desarrolloproductos;
ERROR 1292 (22007): Truncated incorrect INTEGER value: ''

INSERT INTO PRODUCTOS (codProducto)
SELECT CONVERT(codigo, UNSIGNED)
FROM desarrolloproductos;
ERROR 1292 (22007): Truncated incorrect INTEGER value: ''

any suggestions?

The problem was some lost wrong characters at the varchars column. Also after that, I realised that the string representation was bigger than a normal int, so I had to change the type to bigint . problem solved, thank you –
