I am getting the following error in my code:
org.springframework.jdbc.BadSqlGrammarException: PreparedStatementCallback; bad
SQL grammar [insert into bulletins (date, name, subject, note, approved) values
(?, ?, ?, ?, ?)]; nested exception is com.mysql.jdbc.exceptions.MySQLSyntaxError
Exception: Unknown column 'date' in 'field list'
This line is in my Spring controller.
bulletinDAO.writeBulletin(bulletin);
The actual place in my DAO class where I'm trying to write using Hibernate.
public void writeBulletin(Bulletin bulletin) {
try {
Session session = sessionFactory.openSession();
Transaction tx = session.beginTransaction();
session.save(bulletin);
tx.commit();
} catch (Exception e) {
System.out.println(e.toString());
}
}
Here is my model class.
#Entity
#Table(name="login")
public class Bulletin {
#Id
#Column(name="id")
#GeneratedValue
private int id;
#Column(name="bulletin_date")
private String date;
#Column(name="name")
private String name;
#Column(name="subject")
private String subject;
#Column(name="note")
private String note;
#Column(name="approved")
private boolean approved;
// Getters and setters follow
}
Finally, here is the layout of the table.
+---------------+---------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+---------------+---------------+------+-----+---------+----------------+
| id | int(11) | NO | PRI | NULL | auto_increment |
| bulletin_date | varchar(10) | YES | | NULL | |
| name | varchar(30) | YES | | NULL | |
| subject | varchar(50) | YES | | NULL | |
| note | varchar(2500) | YES | | NULL | |
| approved | tinyint(1) | YES | | NULL | |
+---------------+---------------+------+-----+---------+----------------+
There must be something wrong with your getters and setters.
I would recommend changing the property name from date to bulletinDate. And then set & get it correctly...
#Column(name="bulletin_date")
private String bulletinDate;
public String getBulletinDate() {
return bulletinDate;
}
public void setBulletinDate(String bulletin_date) {
this.bulletinDate = bulletin_date;
}
Your issue is here
[insert into bulletins (date, name, subject, note, approved)]
Whereas you need bullletin_date.
From experience i needed to rebuild the project completely to ensure that right column name is referenced.
Clear your project cache and rebuild it.
Let me know how you go and i'll help further if it doesn't help.

I need to insert a null value, instead of empty string into my H2-Database.
My entity looks like this:
#Entity
#Getter
#Setter
#Builder
#AllArgsConstructor
#NoArgsConstructor
public class Link extends Auditable implements Serializable {
private static final long serialVersionUID = -5337989744648444109L;
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
#NotEmpty(message = "title is required")
#Column(length = 50)
private String title;
#Column(unique = true, nullable = true)
private String url;
}
and my sql-statment with values, which will be generated from Hibernate looks like
insert
into
link
(link_id, created_by, creation_date, title, url)
values
(null, ?, ?, ?, ?,) -
session_id=2B491C6BFFE4F66BD63C6453E234D991 user_ip=0:0:0:0:0:0:0:1 2022-12-21 14:21:21,232 |

session_id=2B491C6BFFE4F66BD63C6453E234D991 user_ip=0:0:0:0:0:0:0:1
The last parameter [4] will be filled with null value, but i still have in my H2-Database empty string.
I've tested, that i can insert manually null values into this column with naitve sql statement.
As i've updated SpringBoot from 2.4.5 to 2.7.7, i don't have this bug anymore

Using sqlline, the following tables are created:
+-----------+--------------------------------+-----------------------------+------------+---------+----------+------------+-----------+---------------------------+---------------+
| TABLE_CAT | TABLE_SCHEM | TABLE_NAME | TABLE_TYPE | REMARKS | TYPE_CAT | TYPE_SCHEM | TYPE_NAME | SELF_REFERENCING_COL_NAME | REF_GENERATIO |
+-----------+--------------------------------+-----------------------------+------------+---------+----------+------------+-----------+---------------------------+---------------+
| IGNITE | CacheQueryExampleOrganizations | ORGANIZATION | TABLE | | | | | | |
| IGNITE | CacheQueryExamplePersons | PERSON | TABLE
How do I query these tables in sqlline? I have tried the following and none works:
0: jdbc:ignite:thin://127.0.0.1:10800> select * from person;
Error: Failed to parse query. Table "PERSON" not found; SQL statement:
select * from person [42102-197] (state=42000,code=1001)
0: jdbc:ignite:thin://127.0.0.1:10800> select * from CacheQueryExamplePersons.person;
Error: Failed to parse query. Schema "CACHEQUERYEXAMPLEPERSONS" not found; SQL statement:
select * from CacheQueryExamplePersons.person [90079-197] (state=42000,code=1001)
And logging to sqlline for the specific schema:
0: jdbc:ignite:thin://127.0.0.1:10800/CacheQu> select * from person;
Error: Failed to set schema for DB connection for thread [schema=CACHEQUERYEXAMPLEPERSONS] (state=50000,code=1)
Try enclosing the table scheme name with double quotes.
I have a query from which I want to get a few variables: street, house, locality, region, countryName
let orderDate = datetime('2022-02-10');
let orderId = '0A524A2F83CCB1A311EC827458D6C4F6';
raw_events
| where timestamp between (orderDate .. 1d)
| where messageType == 'OrderPlacedEvent'
| extend messageAsJSON=parse_json(message)
| where messageAsJSON.orderId == orderId
| extend street = messageAsJSON.address.street
| extend house = messageAsJSON.address.house
| extend locality = messageAsJSON.address.locality
| extend region = messageAsJSON.address.region
| extend countryName = messageAsJSON.address.countryName
Is there a better way of achieving that other than executing the same query a few times:
let orderDate = datetime('2022-02-10');
let orderId = '0A524A2F83CCB1A311EC827458D6C4F6';
let street = raw_events
| where timestamp between (orderDate .. 1d)
| where messageType == 'OrderPlacedEvent'
| extend messageAsJSON=parse_json(message)
| where messageAsJSON.orderId == orderId
| project street = messageAsJSON.address.street;
let house = raw_events
| where timestamp between (orderDate .. 1d)
| where messageType == 'OrderPlacedEvent'
| extend messageAsJSON=parse_json(message)
| where messageAsJSON.orderId == orderId
| project street = messageAsJSON.address.house;
print toscalar(street),toscalar(house);
UPDATE
Made it the following way
let addres2look4 = raw_events
| where timestamp between (orderDate .. 1d)
| where messageType == mType
| where message.orderId == orderId
| project address = message.address
| evaluate bag_unpack(address);
let countryName = toscalar(addres2look4 | project countryName);
let region = toscalar(addres2look4 | project region);
let locality = toscalar(addres2look4 | project locality);
let street = toscalar(addres2look4 | project street);
let house = toscalar(addres2look4 | project house);
Here's an efficient way to achieve this (note the use of the materialize() function):
let addres2look4 = materialize(
raw_events
| where timestamp between (orderDate .. 1d)
| where messageType == mType
| where message.orderId == orderId
| project address = message.address
| evaluate bag_unpack(address));
let countryName = toscalar(addres2look4 | project countryName);
let region = toscalar(addres2look4 | project region);
let locality = toscalar(addres2look4 | project locality);
let street = toscalar(addres2look4 | project street);
let house = toscalar(addres2look4 | project house);
The materialize() function caches the subquery's result during the time of query execution, so that the subsequent let statements will be much faster.
Is there any way to get the scenario context outline example values i mean all the values in to a table
Scenario Outline: Create a Matter
Given I enter "< parameter1 >"
Then I enter "<parameter2>"
Then I enter "<parameter3>"
Then I enter "<parameter4>"
Then review all the parameters entered above in this final step
Examples:
| parameter1 | Paramter2|Parameter3|Parameter4|....|parameter14|
| value |value2 |value3 |value4 |....|value14|
in the above scenario is there any way to get all the example values in step4 to a table
I know I can set ScenarioContext.Current[parameter1] = value in each step
In my case I have 14 parameters which are used in each step but in the final step i need to use all the 14 parameters
is there any way I get the example values in to table.
I don't want to break in to smaller scenario
like below
Scenario: breaking in to smaller chunks
Given I enter the following
| parameter1 | Paramter2|
| value |value2|
Here is something I use that may help. Andreas is the expert though on this stuff and he probably has a better idea. Since your format was less than ideal, I used a basic scenario.
Change it to a "Scenario" and Drop the "Scenario Outline".
The feature looks like this:
Scenario: Validate Shipping Fees
When the user enters the State then we can verify the city and shipping fee
| City | State | Shipping |
| Boulder | Colorado | 6.00 |
| Houston | Texas | 8.00 |
Add the Table.
public class ShippingTable
{
public string City { get; set; }
public string State { get; set; }
public string Shipping { get; set; }
}
Then in your step:
[When(#"the user enters the State then we can verify the city and shipping fee")]
public void WhenTheUserEnterTheStateThenWeCanVerifyTheCityAndShippingFee(Table table)
{
var CityState = table.CreateSet<ShippingTable>();
foreach (var row in CityState)
{
try
{
Pages.CheckoutPage.SelectState(row.State);
Pages.CheckoutPage.SelectCity(row.City);
var recdPrice = Pages.CheckoutPage.GetShippingPrice;
Assert.AreEqual(row.shipping, recdPrice);
}
catch (Exception)
{
throw new Exception("This is jacked up");
}
}
}
Problem
I use hibernate to store data in an MySQL database. I now want to store a Company and one of its Branches.
The company:
#Entity
#Table(name="company")
public class Company {
#Id
#GeneratedValue
#Column(name="id")
private int id;
#Column(name="name")
private String name;
#ManyToMany(cascade = CascadeType.ALL)
#JoinTable(name="company_branch_join",
joinColumns={#JoinColumn(name="company_id")},
inverseJoinColumns={#JoinColumn(name="branch_id")})
private Set<CompanyBranch> branches;
// Getters and setters...
}
And the branch:
#Entity
#Table(name="company_branch")
public class CompanyBranch {
#Id
#GeneratedValue
#Column(name="id")
private int id;
#Column(name="branch")
private String branch;
#ManyToMany(mappedBy="branches", cascade = CascadeType.ALL)
private Set<Company> companies;
// Getters and setters...
}
Question
The code works and i can insert the data in the join table. The problem is the override policy regarding the branches. My branch table in the database is already filled with branches and its IDs so i don't want to modify the data. However on an company-insert the branches associated with the company get stored again and override the data with the same ID in the database. How can I prevent this behavior?
CompanyBranch cb1 = new CompanyBranch();
cb1.setId(1);
cb1.setBranch("Manufacturing");
CompanyBranch cb2 = new CompanyBranch();
cb2.setId(2);
cb2.setBranch("DONT-INSERT");
Company c = new Company();
c.setName("[Random-Company-Name]");
c.addBranch(cb1);
c.addBranch(cb2);
CompanyManager cm = new CompanyManagerImpl();
cm.saveCompany(c);
The branch table before execution looks like this:
| id | branch |
+----+----------------+
| 1 | Manufacturing |
| 2 | IT |
|... | ... |
The table should not change. But after execution it looks like this:
| id | branch |
+----+----------------+
| 1 | Manufacturing |
| 2 | DONT-INSERT |
|... | ... |
Instead of creating new branch instances with the new operator, retrieve a reference to them using EntityManager.getReference(), e.g.:
CompanyBranch cb1 = entityManager.getReference(CompanyBranch.class, 1);
