(
COMMANDE_COM_CODE_POSTAL int
,COMMANDE_COM_COMMUNE string
... ,COMMANDE_COM_MONTANT double(12)
)

the correct code should be :
{quote}... ,COMMANDE_COM_MONTANT double
{quote}
It seems that SqlUtil class should not include "double" as a type with scale
{color:#000080}public static boolean {color}isScaleApplicable(String typeName) {
{color:#000080}return
{color}DataType.{color:#660e7a}NUMBER_FAMILY{color}.contains(typeName) &&
!DataType.{color:#660e7a}INTEGER_FAMILY{color}.contains(typeName);
}
should be changed for something similar to :
{color:#000080}public static boolean {color}isScaleApplicable(String typeName) {
{color:#000080}return {color}!{color:#008000}"double"{color}.equals(typeName)
&& DataType.{color:#660e7a}NUMBER_FAMILY{color}.contains(typeName) &&
!DataType.{color:#660e7a}INTEGER_FAMILY{color}.contains(typeName);
}
