Having a text[] column named name in database table named Employee , i want to check if certain value is present in array using criteria query

Table name: Employee
I have an array column name: ["a","b","c"]
and a value name -> "a" which i want to check if it is present in array.
Through sql query i am able to do using ANY clause:
SELECT *
FROM EMPLOYEE WHERE 'a' = ANY(name)
But when i try to do same through criteria query I run into issues as ANY() uses subquery as param.
Can someone help how to achieve same using criteria api without using subquery?
I have tried isMember,Any() In() using criteria query but none of that works.

in #Query , I need to query DB to select a row where a column is null. I am using JpaRepository

I have tried using below query
#Query(value = "select E.SRC,E.TRGT,E.EVNT_STTS,E.ADDL_ATTR from EVNT.EVNT_LOG E where E.EVNT_ID=:eventId and E.ADDL_ATTR IS NULL" , nativeQuery = true)
List<AggregationLog> findByEventIdAndTargetAndAdditionalAttributeWithNULL(#Param("eventId") Long eventId);
in above query I am getting invalid column name.
Please guide me to select a row with eventID and addl_attr as null.

Well... invalid column means oracle cannot resolve the column name in the query. That usually means 1 of 2 things:
A Typo
The columns were created with case sensitivity. Whoever created the table surrounded the column names with double quotes and put column names in something other than all caps. Do a "DESCRIBE <table_name>" in sqlplus, sqldeveloper or any other client and check if the column names are all upper case. If they're not, you will need to enclose them in double quotes in your query with the name matching exactly what you see.

jdbc.SQLServerException on group by clause

While executing this code in my project:
Integer countObj = (Integer) ht.findByCriteria(criteria.setProjection(Projections.rowCount())).get(0);
I get the following exception:
com.microsoft.sqlserver.jdbc.SQLServerException: Column "PRODUCT_TASK.PRODUCT_TASK_ID" is invalid in the ORDER BY clause because it is not contained in either an aggregate function or the GROUP BY clause."
Here I am using two tables.
Product_task with product_task_id as primary key
Product_info with product_info_id as primary key
product_info_id is the foreign key for Product_task.
By executing that query I will get count.
I am getting this SQL query in my logs:
select count(*) as Count from PRODUCT_TASK pt inner join
PRODUCT_INFO pin on pt.PRODUCT_INFO_ID=pin.PRODUCT_INFO_ID
where pin.UPC like ? order by pt.PRODUCT_TASK_ID asc**
I know how to change SQL query (group by clause need to be there) but I don't know how to modify the Hibernate query in order to get the result.

You just need to use Projections's .groupProperty() method in your Criteria.
groupProperty
public static PropertyProjection groupProperty(String propertyName)
A grouping property value
Your code would be like this:
Integer countObj = (Integer) ht.findByCriteria(criteria.setProjection(Projections.rowCount()
.add(Projections.groupProperty("product_task_id"))))
.get(0);

Merge and When Matched query giving an error sql server

I have a query which I am trying to test. The query should update the data if it finds data in the table with existing primary key. If it doesn't then insert into the table.
The Primary key is of type int and in the properties I can see Identity is set to "True" which I assume it means that it will automatically set the new id for the primary if it is inserted.
MERGE INTO Test_table t
USING (SELECT 461232 ID,'Test1-data' Fascia FROM Test_table) s
ON (t.ID = s.ID)
WHEN MATCHED THEN
UPDATE SET t.Fascia = s.Fascia
WHEN NOT MATCHED THEN
INSERT (Fascia)
VALUES (s.Fascia);
The issue here is this query doesn't work and it never inserts the data or updates. Also, query gets compiled and I don't get any compilation error
Also the reason I want this query is to work because then I will use Java prepared statement to query the database so I am assuming I can do
SELECT ? ID,? Fascia FROM Test_table
So that I can pass the values with set methods in java.
Please let me know if there is something wrong in my query.

You are selecting from the target table as your source.
You either need to remove your FROM Test_table or have at least 1 row in Test_table prior to your merge.

MERGE INTO Test_table t
USING (SELECT 461232 ID,'Test1-data' Fascia --FROM Test_table
) s
ON (t.ID = s.ID)
WHEN MATCHED THEN
UPDATE SET t.Fascia = s.Fascia
WHEN NOT MATCHED THEN
INSERT (Fascia)
VALUES (s.Fascia);

Hibernate - Could not resolve property

I have table Users which contains column iduser (long) fk -> to table login to column id_user (long).
But I don't want to map table login into users. I just want to use this column iduser in Users like normal column and find specific object.
When I wrote something like this:
...
criteria.add(Restrictions.eq(ID_USER, (long) 3);
...
The error will appear:
could not resolve property: iduser of: model.domain.User
But when I used standard SQLQuery:
Query query = session.createSQLQuery("select * from Users where iduser = 3");
List list = query.list();
it will found the specific object.
Any ideas how to solve this problem?

Names of the persistent attributes are case sensitive. Because name of the attribute is idUser, it is expected that attribute iduser (lower case 'u') cannot be found. When Criteria or HQL is used, it is names of the attributes, not the names of the database columns that matters.
