java - 10-digits BigDecimal cannot be saved in NUMBER(10, 2) column -

in oracle 12 database, 1 of column defined number(10,2). goal store numbers one: 12345678.12. actually, can store such number thank oracle sql developer, format matching.

through hibernate-java app, when update entity containing following values, works:

1.12 12.12 123.12 1234.12 12345.12 123456.12 

but following, error

1234567.12 12345678.12  ora-01438: value larger specified precision allowed column 

it looks number(8, 2)...

the field in @embeddable class, type bigdecimal, without field annotation:

@entity @table(...) public class classa implements serializable {      @embedded     private classb bobject; }  @embeddable public class classb implements serializable {      @embedded     private classc cobject; }  @embeddable public class classc implements serializable {      private bigdecimal myfield; } 

is there other things can override column definition?

the first number in decimal type precision, second digit scale.
oracle's documentation:

you can specify precision (the total number of digits, both left , right of decimal point) , scale (the number of digits of fractional component).

if have 10 digits before fraction, need decimal(12,2).

the error see comes oracle, not hibernate, doubt changing entity configuration solve issue.
