Conversion failed in host variable or * N parameter

Question

I get this error in the Insert statement in the AS400 database using Java with JDBC.

Answer 1

I realized I had a number field with a length of 4 and decimal digits 2. In my insert, I tried to insert 100 into this number field that gave this error.

I altered the table and made it numeric with length 9 and decimal digits 2 
and the insert worked.

although the error indicates the error "Conversion Error", this is actually the wrong field length.
