调用oracle存储过程时出现以下错误

异常说明：从行读取的主键[DatabaseRecord（ retval =＆gt;空值 error_message =＆gt;检测到执行期间检测到null为空。主键不能包含null。查询：ReadAllQuery（name =＆＃34; CCM_ASSIGN_LOOP＆＃34; referenceClass = CcmAssignLoop）

我的实体

@Entity
@NamedStoredProcedureQuery(name="CCM_ASSIGN_LOOP", procedureName="TCS.CCM_ASSIGN_LOOP",         resultClass=CcmAssignLoop.class,  
parameters={  
    @StoredProcedureParameter(queryParameter="psubno",name="psubno",direction=Direction.IN),  
    @StoredProcedureParameter(queryParameter="upd_user",name="upd_user",direction=Direction.IN),  
    @StoredProcedureParameter(queryParameter="ccloop_in",name="ccloop_in",direction=Direction.IN),
    @StoredProcedureParameter(queryParameter="ccstage_in",name="ccstage_in",direction=Direction.IN),
    @StoredProcedureParameter(queryParameter="retval",name="retval",direction=Direction.OUT),
    @StoredProcedureParameter(queryParameter="error_message",name="error_message",direction=Direction.OUT)
 }  
)

public class CcmAssignLoop implements Serializable {

private static final long serialVersionUID = 1L;

public CcmAssignLoop() {
    super();
}

@Id
private String  psubno;
private String  upd_user;
private String  ccloop_in;
private BigDecimal  ccstage_in;
private String  retval;
private String  error_message;

public String getPsubno() {
    return psubno;
}
public void setPsubno(String psubno) {
    this.psubno = psubno;
}
public String getUpd_user() {
    return upd_user;
}
public void setUpd_user(String upd_user) {
    this.upd_user = upd_user;
}
public String getCcloop_in() {
    return ccloop_in;
}
public void setCcloop_in(String ccloop_in) {
    this.ccloop_in = ccloop_in;
}
public BigDecimal getCcstage_in() {
    return ccstage_in;
}
public void setCcstage_in(BigDecimal ccstage_in) {
    this.ccstage_in = ccstage_in;
}
public String getRetval() {
    return retval;
}
public void setRetval(String retval) {
    this.retval = retval;
}
public String getError_message() {
    return error_message;
}
public void setError_message(String error_message) {
    this.error_message = error_message;
}

}

以下是调用存储过程的代码

Query q = tabsEm.createNamedQuery("CCM_ASSIGN_LOOP");
        q.setParameter("psubno", subno);
        q.setParameter("upd_user", "abc");
        q.setParameter("ccloop_in", "xyz");
        q.setParameter("ccstage_in", new BigDecimal(5));

      //  CcmAssignLoop ccmAssignLoop   =   (CcmAssignLoop)q.getSingleResult();

        q.getResultList();

上面提到的列不是主键，我收到此错误。

更新

我在oracle上的程序就像

一样

CREATE OR REPLACE PROCEDURE TCS.CCM_ASSIGN_LOOP(PSUBNO IN VARCHAR2, UPD_USER IN VARCHAR2, CCLOOP_IN IN VARCHAR2, CCSTAGE_IN IN NUMBER, RETVAL OUT VARCHAR2, ERROR_MESSAGE OUT VARCHAR2)
     IS
OLD_CCSTAGE     CCM_USER_INFO.CCLOOP_STAGE%TYPE;
OLD_CCLOOP      CCM_USER_INFO.CCLOOP%TYPE;
PROC_CONTRNO    CRM_USER_INFO.CONTRNO%TYPE;
TEMP_COUNT      NUMBER;
RET_VAL         VARCHAR2(100);
V_ERROR_MESSAGE VARCHAR2(256);

我可以看到RETVAL和RET_VAL，这可能是因为这个错误吗？

此致

Answer 1

可能是区分大小写的问题。尝试将queryParameter属性值全部设为大写，例如：

@StoredProcedureParameter(queryParameter="PSUBNO",name="psubno",direction=Direction.IN),

我认为，如果您没有使用Column注释指定名称，则默认情况下数据库列名称（以及存储过程参数）是大写的。

Answer 2

您正在设置“resultClass = CcmAssignLoop.class”，这意味着该过程将返回数据以构建此类的实例，您的过程没有，所以不要设置它。然后你将获得原始数据。
