Question

我正在使用IBATIS 2.3.4版本。数据库是MS SQL Server。

我正在尝试在表T_PROFILE中插入记录，该表具有Identity主列自动生成的值。

我的IBATIS配置

<insert id="insertProfile" parameterClass="profileDO" useGeneratedKeys="true" keyProperty="profileId">
        INSERT INTO T_PROFILE (E_ID,PROFILE_NAME,DEFAULT_PROFILE)
        VALUES(#eId#, #profileName#, #isDefaultProfile#)

        <selectKey resultClass="java.lang.Long" keyProperty="profileId" >
            SELECT @@IDENTITY AS profileId
        </selectKey>
    </insert>

正在给出错误

Caused by: com.ibatis.common.xml.NodeletException: Error parsing XML.  Cause: org.xml.sax.SAXParseException: Attribute "useGeneratedKeys" must be declared for element type "settings".

Answer 1

如果您在数据库中设置了标识列，则以下查询本身将起作用。 useGeneratedKeys不需要。

 <insert id="insertProfile" parameterClass="profileDO" >
    INSERT INTO T_PROFILE (E_ID,PROFILE_NAME,DEFAULT_PROFILE)
    VALUES(#eId#, #profileName#, #isDefaultProfile#)

    <selectKey resultClass="long" keyProperty="profileId" >
        SELECT @@IDENTITY AS profileId
    </selectKey>
</insert>
