我试图将数据库中的字段更新为null为整数字段.我试图用hibernate做到这一点.我可以将像String这样的对象字段和任何其他对象设置为null但不是整数.

<?xml version="1.0" encoding="UTF-8"?>

<class name="App_Users" table="app_users" schema="bidtool">

    <id name="userId" type="int" column="user_id">

    <property name="userType" type="int">
        <column name="user_type" />
    </property>

    <many-to-one class="MasterOrg"  fetch="select"  name="masterOrg">
        <column name="master_org_id" />
    </many-to-one>

   <many-to-one class="CarrierScac"  fetch="select" name="carrierScac">
        <column name="scac" />
    </many-to-one>


     <one-to-one class="AppUserDetails" fetch="select" name="details" constrained="true"/>

    <set name="profiles" inverse="true"> …

我需要使用数据类型来存储整数值,但我需要一个等效于BigInt的数据类型.Dynamics AX中有没有？
