I've been receiving the "ORA-00923: FROM keyword not found where expected" error in my code. I am trying to implement CRUD operations using Spring Hibernate. I've checked for syntax errors as well as quotes in my sql query, but can't seem to detect anything out of the ordinary.
User Class:
package com.spring.model;
import javax.persistence.*;
#Entity
#Table(name="PATIENT_MODEL")
public class User {
private int id;
private String patientFirstName;
private String patientLastName;
private String patientEmail;
private String patientAddress1;
private String patientAddress2;
#Id
#GeneratedValue
#Column(name="PATIENT_ID")
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
#Column(name="PATIENT_FIRST_NAME")
public String getPatientFirstName() {
return patientFirstName;
}
public void setPatientFirstName(String patientFirstName) {
this.patientFirstName = patientFirstName;
}
#Column(name="PATIENT_LAST_NAME")
public String getPatientLastName() {
return patientLastName;
}
public void setPatientLastName(String patientLastName) {
this.patientLastName = patientLastName;
}
#Column(name="PATIENT_EMAIL_ADDRESS")
public String getPatientEmail() {
return patientEmail;
}
public void setPatientEmail(String patientEmail) {
this.patientEmail = patientEmail;
}
#Column(name="PATIENT_ADDRESS_LINE 1")
public String getPatientAddress1() {
return patientAddress1;
}
public void setPatientAddress1(String patientAddress1) {
this.patientAddress1 = patientAddress1;
}
#Column(name="PATIENT_ADDRESS_LINE_2")
public String getPatientAddress2() {
return patientAddress2;
}
public void setPatientAddress2(String patientAddress2) {
this.patientAddress2 = patientAddress2;
}
}
The problem is the #Column(name="PATIENT_ADDRESS_LINE 1"). Could it be the database column is actually named PATIENT_ADDRESS_LINE_1?
If you really need to use column whose name includes one or more spaces, then you need to instruct Hibernate to quote the column name. Also see Oracle documentation.

I have simple Sprinngboot app where actual database is PostgreSQL.
My model:-
#Table("carrier")
#Entity
public class MyCarrier {
#Id
#Column("id")
private UUID id;
#Size(
max = 100
)
#Column("carrier_name")
private String carrierName;
#Size(
max = 3
)
#Column("smdg_code")
private String smdgCode;
#Size(
max = 4
)
#Column("nmfta_code")
private String nmftaCode;
public MyCarrier() {
}
public UUID getId() {
return this.id;
}
public String getCarrierName() {
return this.carrierName;
}
public String getSmdgCode() {
return this.smdgCode;
}
public String getNmftaCode() {
return this.nmftaCode;
}
public void setId(final UUID id) {
this.id = id;

}
protected boolean canEqual(final Object other) {
return other instanceof Carrier;
}
}
Repository:-
#Repository
public interface MyCarrierRepository extends JpaRepository<MyCarrier, Long> {
}
Controller:-
#RestController
#RequestMapping(path = "/upload")
public class ReactiveUploadResource {
Logger LOGGER = LoggerFactory.getLogger(ReactiveUploadResource.class);
private final SqlRequestHandler sqlRequestHandler;
#Autowired
private MyCarrierRepository myCarrierRepository;
public ReactiveUploadResource(SqlRequestHandler sqlRequestHandler) {
this.sqlRequestHandler = sqlRequestHandler;
}
}
I got this error:-
Description:
Field myCarrierRepository in com.consumer.controller.ReactiveUploadResource required a bean of type 'com.consumer.repository.MyCarrierRepository' that could not be found.
What is missing? Why Springboot doesn't find this repository?
You have to put the repository inside the package at the same level as Application class the packages to allow Spring boot to scan it
I am attempting to update an Employee row in my Employee table using JDBI. However, the bindBean method doesn't appear to like my bean. I have included getters and setters. The bean has a public default constructor. The property names of the object are an exact match for the database column names. So the LastName String for instance, corresponds to a LastName database column. Exact match. What am I doing wrong here? Am I misconstruing how bindBean works? I also tried this same code with a prefix in front of the :parameters, still no dice.
EDIT: After a little more research, I believe the issue is coming from the fact that my column names and properties start with capital letters. Annotating my getters and setters with #ColumnName and the appropriate uppercase column names does not appear to be helping though.
SOLVED: Easy solution to this problem is to rename the named parameters in the query itself to match a lowercase version of the property names. i.e if the property is called Name, change the parameter in the query to :name and the problem is resolved without touching your beans or your database columns.
Dao Method:
#Override
public void updateEmployee(Employee empl){
try(Handle handle = daoFactory.getDataSourceController().open()){
handle.createUpdate("UPDATE Employees SET LastName = :LastName, FirstName = :FirstName, EmailAddress = :EmailAddress, OnVacation = :OnVacation, Active = :Active, EscalationLevel = :EscalationLevel," +
" ScheduleExempt = :ScheduleExempt, GroupID = :GroupID, ScheduleID = :ScheduleID, SecurityGID = :SecurityGID, JobTitle = :JobTitle, Blurb = :Blurb WHERE IDX = :IDX")
.bindBean(empl)
.execute();
handle.commit();
}
catch(Exception e){
if(verbose){ e.printStackTrace(); }
logger.logError("Web-EmployeeDaoService-E04", "Error updating single user in DB.");
}
}
And my bean:
package app.pojos.Employee;
import java.io.Serializable;
import java.sql.Timestamp;
public class Employee implements Serializable {
private int IDX;
private String LastName;
private String FirstName;
private String EmailAddress;

public void setActive(boolean Active){ this.Active = Active; }
public int getEscalationLevel(){ return EscalationLevel; }
public void setEscalationLevel(int EscalationLevel){ this.EscalationLevel = EscalationLevel; }
public int getScheduleID(){ return ScheduleID; }
public void setScheduleID(int ScheduleID){ this.ScheduleID = ScheduleID; }

See this response for clarity. If you're like me and made the mistake of going against best practice naming conventions and capitalized all of your bean properties, this is an easy solution. You only need to change how you reference the properties in your create/update/insert queries and nothing else.
Hello Stack overflow,
I have the following Problem:
I have these entity classes:
public class UnknownEntity extends NetworkEntity{
#Id
#GeneratedValue(strategy = UuidStrategy.class)
private String id;
#Override
public void setId(String id) {
this.id = id;
}
#Override
public String getId() {
return id;
}
}
#NodeEntity
public class NetworkEntity {
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
#Id
protected String id;
public List<NetworkInterfaceEntity> getInterfaces() {
return interfaces;
}
public void setInterfaces(List<NetworkInterfaceEntity> interfaces) {
this.interfaces = interfaces;
}
#Relationship(type = "is_composed_of")
protected List<NetworkInterfaceEntity> interfaces ;
}
#NodeEntity
public class NetworkInterfaceEntity {
public String getInterfaceId() {
return interfaceId;
}
public void setInterfaceId(String interfaceId) {
this.interfaceId = interfaceId;
}
public String getIpAddress() {
return ipAddress;
}
public void setIpAddress(String ipAddress) {
this.ipAddress = ipAddress;
}
public String getNetmask() {
return netmask;
}
public void setNetmask(String netmask) {
this.netmask = netmask;
}
public String getMacAddress() {
return macAddress;
}
public void setMacAddress(String macAddress) {
this.macAddress = macAddress;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public InterfaceState getState() {
return state;
}
public void setState(InterfaceState state) {
this.state = state;
}
public List<NetworkInterfaceEntity> getSubInterfaces() {
return subInterfaces;
}
public void setSubInterfaces(List<NetworkInterfaceEntity> subInterfaces) {
this.subInterfaces = subInterfaces;
}
public long getBytesSent() {
return bytesSent;
}
public void setBytesSent(long bytesSent) {
this.bytesSent = bytesSent;
}
public long getBytesRecived() {
return bytesRecived;
}
public void setBytesRecived(long bytesRecived) {
this.bytesRecived = bytesRecived;
}
#Id
private String interfaceId;
private String ipAddress;
private String netmask;
private String macAddress;
private String name;
private InterfaceState state;
#Relationship(type = "is_composed_of")
private List<NetworkInterfaceEntity> subInterfaces;
private long bytesSent;
private long bytesRecived;
}
When I now try to query the UnknownEntities via a Neo4j Crud Repository with a custom #Query Method, the UnknownEntities wont be nested with the necessary NetworkInterfaceObjects, even tough my query returns these.
public interface UnknownEntityRepository extends CrudRepository<UnknownEntity,String> {
#Query("MATCH (u:UnknownEntity)-[:is_composed_of]->(i:NetworkInterfaceEntity) WHERE i.ipAddress IN {0} WITH u as unknown MATCH p=(unknown)-[r*0..1]-() RETURN collect(unknown),nodes(p),rels(p)")
List<UnknownEntity> searchMachinesByIp(List<String> ipAddresses);
}
In this particular case the NetworkInterfaceEntities do not contain more subInterfaces, so I only want the NetworkInterfaceEntities that belong the the UnknownEntity. But when I use this Query I only get UnknownEntities where the NetworkInterfaceList is null. I even tried different Querys to no avail for example:
"MATCH p=(u:UnknownEntitie)-[:is_composed_of]-(n:NetworkInterfaceEntity) WHERE n.ipAddress in {0} RETURN collect(n),nodes(p),rels(p)".
My Question is, if what I want is even possible with SDN4 Data and if it is, how I can achieve this, Since my alternative is to query the database for every NetworkInterface separately, which I think is really ugly.
Any help would be much appreciated.
please try if returning the full path like this:
public interface UnknownEntityRepository extends CrudRepository<UnknownEntity,String> {
#Query("MATCH (u:UnknownEntity)-[:is_composed_of]->(i:NetworkInterfaceEntity) WHERE i.ipAddress IN {0} WITH u as unknown MATCH p=(unknown)-[r*0..1]-() RETURN p")
List<UnknownEntity> searchMachinesByIp(List<String> ipAddresses);
}
works for your. If not, try naming the objects in question, i.e. RETURN i as subInterfaces works for you.
Are you using Spring Data Neo4j 4 or 5? If you're on 4, consider the upgrade to 5 to be on a supported level.
Please let me know, if this helps.
I am new to implement Azure Mobile Service. I have refer the demo of ToDoItem given by Azure.
In same manner i have make class User for my own app. Then I am inserting the data in to the MobileServiceTable but it gives me error like below:
{"message":"The operation failed with the following error: 'A null store-generated value was returned for a non-nullable member 'CreatedAt' of type 'CrazyLabApp.Models.User'.'."}
I have not created any field like this as it is not created in ToDoItem demo as well. I have seen that there are 4 fields that are by Default created by the MobileServiceTable. createdAt is one of the field of that.
I am wonder about whats wrong i am doing.
Check my below Userclass:
public class User {
#com.google.gson.annotations.SerializedName("id")
private String ServiceUserId;
#com.google.gson.annotations.SerializedName("email")
private String Email;
#com.google.gson.annotations.SerializedName("firstname")

public String getProfilePic() {
return ProfilePic;
}
public void setProfilePic(String profilePic) {

}
public String getEmail() {

}
public void setServiceUserId(String serviceUserId) {
ServiceUserId = serviceUserId;
}
#Override
public boolean equals(Object o) {
return o instanceof User && ((User) o).ServiceUserId == ServiceUserId;
}
}
Also check below code the way i am inserting it:
final User u = new User();
u.setFirstName(mName);
u.setEmail(mEmail);
u.setProfilePic(mUrl);
mUserTable = mClient.getTable(User.class);
// Insert the new item
new AsyncTask<Void, Void, Void>(){
#Override
protected Void doInBackground(Void... params) {
try {
final User entity = mUserTable.insert(u).get();
} catch (Exception e){
//createAndShowDialog(e, "Error");
System.out.println("Error: "+e.toString());
}
return null;
}
}.execute();
Please help me in this.
The "_createdat" column will be populated automatically by Azure Mobile Services so there is no need to include it in your model. Delete this property from the User class. Its presence is probably overwriting the auto-populated value with a null.
you can solve this problem by just deleting createdAt column from your user table in azure.
Why this error is coming :
I am not sure But I guess this error is coming because createdAt is a non-nullable member and you cannot left it null.
EDIT :
Another aspect of the system columns is that they cannot be sent by the client. For new tables (i.e., those with string ids), if an insert of update request contains a property which starts with ‘__’ (two underscore characters), the request will be rejected. The ‘__createdAt’ property can, however, be set in the server script (although if you really don’t want that column to represent the creation time of the object, you may want to use another column for that) – one way where this (rather bizarre) scenario can be accomplished. If you try to update the ‘__updatedAt’ property, it won’t fail, but by default that column is updated by a SQL trigger, so any updates you make to it will be overridden anyway.

I'm using BlazeDS in Tomcat7 and Flex. I'm trying to use custom classes between the client and server.
In as:
package
{
[Bindable]
[RemoteClass(alias="remoting.Product")]
public class Product
{
public var name:String;
public var id:int;
public var isVisible:Boolean;
}
}
In Java:
package remoting;
public class Product {
public String name;
public int id;
public Boolean isVisible;
public Product(){
name = "Product 0.1";
id = 123;
isVisible = false;
}
public void setName(String _name){
name = _name;
}
public void setId(int _id){
id = _id;
}
public void setVisible(Boolean _isVisible){
isVisible = _isVisible;
}
}
Service part:
public Product echo() {
Product product = new Product();
product.setId(123);
product.setName("My Product");
product.setVisible(true);
return product;
}
I can successfully set the destination of the RemoteObject and call the echo() method. The result event fires up, with the Product object in event.result. However, it does not contain any sensible data. The variables from AS class just get initialized with null, 0 and true values. I'm wondering what's the problem. I tried returning a String with parameters from Product and it works fine, so they get set fine. The problem is in mapping.
I could go another way and implement Externalizable but I don't understand this part from the example:
name = (String)in.readObject();
properties = (Map)in.readObject();
price = in.readFloat();
What if there is a number of strings?
Cheers.
In java class: use private fields and implement getters.
package remoting;
public class Product {
private String name;
private int id;
private Boolean isVisible;
public Product() {
name = "Product 0.1";
id = 123;
isVisible = false;
}
public void setName(String _name){
name = _name;
}
public String getName(){
return name;
}
public void setId(int _id){
id = _id;
}
public int getId(){
return id;
}
public void setIsVisible(Boolean _isVisible){
isVisible = _isVisible;
}
public Boolean getIsVisible() {
return isVisible;
}
}
You could also switch from BlazeDS to GraniteDS: the latter has a powerful transparent externalization mechanism as well as code generation tools that can really save your time (see documentation here).
