Using MySQL database in Jdeveloper

Question

I am using MySQl database in my applicaion.I have successfully created connection to the database and have created entity beans from the tables and a session bean as well to use the entity beans
now when i am trying to call persistEntity(object obj) of session bean, basically to insert records into tables.
i am getting following exception :
Internal Exception: com.mysql.jdbc.exceptions.MySQLSyntaxErrorException: You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near '"tdmce_approval_status" (APPROVALLEVEL, DOCREFNO, STATUS, COMMEError Code: 1064
Call:INSERT INTO "tdmce_approval_status" (APPROVALLEVEL, DOCREFNO, STATUS, COMMENTS, DMCETYPE, ACTIONDATE) VALUES (?, ?, ?, ?, ?, ?)
     bind => [1, 12355, Approved, abcd, import, 12/03/2008]
i believe this insert query is automatically generated by Jdeveloper. have tried executing the same query in sql sheet it has worked perfectly fine.
Can any one please suggest on this ?

Hi Frank,
thanks for your response, there are only setters & getters method in my entity
my entity look like this
package buslogic;
import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.IdClass;
import javax.persistence.NamedQuery;
import javax.persistence.Table;
@Entity
@NamedQuery(name = "TdmceApprovalStatus.findAll",
query = "select o from TdmceApprovalStatus o")
@Table(name = "\"tdmce_approval_status\"")
@IdClass(TdmceApprovalStatusPK.class)
public class TdmceApprovalStatus implements Serializable {
@Column(nullable = false)
private String actiondate;
@Id
@Column(nullable = false)
private Integer approvallevel;
private String comments;
@Column(nullable = false)
private String dmcetype;
@Id
@Column(nullable = false)
private String docrefno;
@Id
@Column(nullable = false)
private String status;
public TdmceApprovalStatus() {
public String getActiondate() {
return actiondate;
public void setActiondate(String actiondate) {
this.actiondate = actiondate;
public Integer getApprovallevel() {
return approvallevel;
public void setApprovallevel(Integer approvallevel) {
this.approvallevel = approvallevel;
public String getComments() {
return comments;
public void setComments(String comments) {
this.comments = comments;
public String getDmcetype() {
return dmcetype;
public void setDmcetype(String dmcetype) {
this.dmcetype = dmcetype;
public String getDocrefno() {
return docrefno;
public void setDocrefno(String docrefno) {
this.docrefno = docrefno;
public String getStatus() {
return status;
public void setStatus(String status) {
this.status = status;
& session bean class to call the same
package buslogic;
import buslogic.persistance.TdmceApprovalsFlow;
import buslogic.persistance.TdmceApprovalsFlowPK;
import buslogic.persistance.TdmceUserDetails;
import java.util.List;
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
@Stateless(name = "FirstCheckFacade")
public class FirstCheckFacadeBean implements FirstCheckFacade {
@PersistenceContext(unitName = "SOAServices")
private EntityManager em;
public FirstCheckFacadeBean() {
public Object mergeEntity(Object entity) {
return em.merge(entity);
public Object persistEntity(Object entity) {
em.persist(entity);
return entity;
/** <code>select o from TdmceApprovalsFlow o</code> */
public List<TdmceApprovalsFlow> queryTdmceApprovalsFlowFindAll() {
return em.createNamedQuery("TdmceApprovalsFlow.findAll").getResultList();
public void removeTdmceApprovalsFlow(TdmceApprovalsFlow tdmceApprovalsFlow) {
tdmceApprovalsFlow =
em.find(TdmceApprovalsFlow.class, new TdmceApprovalsFlowPK(tdmceApprovalsFlow.getApprovallevel(),
tdmceApprovalsFlow.getDmcetype()));
em.remove(tdmceApprovalsFlow);
/** <code>select o from TdmceUserDetails o</code> */
public List<TdmceUserDetails> queryTdmceUserDetailsFindAll() {
return em.createNamedQuery("TdmceUserDetails.findAll").getResultList();
public void removeTdmceUserDetails(TdmceUserDetails tdmceUserDetails) {
tdmceUserDetails =
em.find(TdmceUserDetails.class, tdmceUserDetails.getUserid());
em.remove(tdmceUserDetails);
Where else can i look for the query?or for mysql i have to configure some property.
