I would like to convert this SQL into either Criteria. I am sorry I don't know which one to use since I'm new to Hibernate. I've done some research, and it looks like both are needed to achieve what I wanted.
My Sql Request
select *
from change.pade pade, change.pade_etat rdp, par.safsit safsit, par.saf saf
where pade.sir = "1245454"
and pade.id_safsit = "1"
and pade.id_safsit = safsit.id
and safsit.cd_s in ("12", "45")
and safsit.fk_saf = saf.id
and saf.cd_ur in "124"
and rdp.fk_pade = pade.id
and rdp.id_etat in "444"
You can use the Hibernate properties instead of writing HQL like this
session.createSQLQuery(String sqlQuery)
see an example here

I know this may sound silly but I've been stuck on this problem for too long!
I'm querying a PostgreSQL repository through JPA using native SQL queries. One of my queries looks like this:
#Query(value = "select * from gs where ?1 = ?2", nativeQuery = true)
public List<GsJsonStore> matchJson(String term, String value);
I'm testing the function using :
List<GsJsonStore> list = repo.matchJson("subject", "'Sub'");
The list is empty on running the query, however when I run the same query through PSQL command line using:
select * from gs where subject = 'Sub';
I get the correct output, records contatining the key-value pair are returned.
Where am I making the mistake?
You can't use parameter for column name. Your query resolves to
select * from gs where 'subject' = '''Sub'''
EDIT: just saw #pozs already posted the same in comment
my problem is about this kind of query :
select * from SOMETABLE where SOMEFIELD in ('STRING1','STRING2');
the previous code works fine within Sql Developer.
The same static query also works fine and returns me a few results;
Query nativeQuery = em.createNativeQuery(thePreviousQuery,new someResultSet());
return nativeQuery.getResultList();
But when I try to parameterize this, I encounter a problem.
final String parameterizedQuery = "select * from SOMETABLE where SOMEFIELD in (?selectedValues)";
Query nativeQuery = em.createNativeQuery(parameterizedQuery ,new someResultSet());
nativeQuery.setParameter("selectedValues","'STRING1','STRING2'");
return nativeQuery.getResultList();
I got no result (but no error in console).
And when I look at the log, I see such a thing :
select * from SOMETABLE where SOMEFIELD in (?)
bind => [STRING1,STRING2]
I also tried to use no quotes (with similar result), or non ordered parameter (:selectedValues), which leads to such an error :
SQL Error: Missing IN or OUT parameter at index:: 1
I enventually tried to had the parentheses set directly in the parameter, instead of the query, but this didn't work either...
I could build my query at runtime, to match the first (working) case, but I'd rather do it the proper way; thus, if anyone has an idea, I'll read them with great interest!
FYI :
JPA version 1.0
Oracle 11G
JPA support the use of a collection as a list literal parameter only in JPQL queries, not in native queries. Some JPA providers support it as a proprietary feature, but it's not part of the JPA specification (see https://stackoverflow.com/a/3145275/1285097).
Named parameters in native queries also aren't part of the JPA specification. Their behavior depends on the persistence provider and/or the JDBC driver.
Hibernate with the JDBC driver for Oracle support both of these features.
List<String> selectedValues = Arrays.asList("STRING1", "STRING2");
final String parameterizedQuery = "select * from SOMETABLE where SOMEFIELD in (:selectedValues)";
return em.createNativeQuery(parameterizedQuery)
.setParameter("selectedValues", selectedValues)
.getResultList();
Instead of:
nativeQuery.setParameter("selectedValues", params);
I had to use:
nativeQuery.setParameterList("selectedValues", params);
This worked for me in derby. parameter without "()".
List<String> selectedValues = Arrays.asList("STRING1", "STRING2");
final String parameterizedQuery = "select * from SOMETABLE where SOMEFIELD in
:selectedValues";
return em.createNativeQuery(parameterizedQuery)
.setParameter("selectedValues", selectedValues)
.getResultList();
Replace this:
nativeQuery.setParameter("selectedValues","'STRING1','STRING2'");
with
List<String> params;
nativeQuery.setParameter("selectedValues",params);
I also faced the same issue.
This is what I did:
List<String> sample = new ArrayList<String>();
sample.add("sample1");
sample.add("sample2");
And now you, can set the sample in params.
I am trying to avoid a sql injection. This topic has been dealt with in Java (How to prevent query injection on Google Big Query) and Php.
How is this accomplished in App Scripts? I did not find how to add a parameter to a SQL statement. Here is what I had hoped to do:
var sql = 'SELECT [row],etext,ftext FROM [hcd.hdctext] WHERE (REGEXP_MATCH(etext, esearch = ?) AND REGEXP_MATCH(ftext, fsearch = ?));';
var queryResults;
var resource = {
query: sql,
timeoutMs: 1000,
esearch='r"[^a-zA-z]comfortable"',
fsearch='r"[a-z,A-z]confortable"'
};
queryResults = BigQuery.Jobs.query(resource,projectNumber);
And then have esearch and fsearch filled in with the values (which could be set elsewhere).
That does not work, according to the doc.
Any suggestions on how to get a parameter in an SQL query? (I could not find a setString function...)
Thanks!
Unfortunately, BigQuery doesn't support this type of parameter substitution. It is on our list of features to consider, and I'll bump the priority since it seems like this is a common request.
The only suggestion that I can make in the mean time is that if you are building query strings by hand, you will need to make sure you escape them carefully (which is a non-trivial operation).
I have a mongo db complex filter generated dynamically which might look like
where_condition = {"$and":[{"column_3": "Offer"}, {"column_2":"MSN"}]}
collection.find(where_condition)
The condition might have unknown depth in $and and $or
Is it possible to find the negative of the where_condition
This does not work
not_condition = {"$not": where_condition}
You'll want to use $nor. Something like this:
where_condition = {"$and":[{"column_3": "Offer"}, {"column_2":"MSN"}]}
not_condition = {"$nor":[{"column_3": "Offer"}, {"column_2":"MSN"}]}
You can find some more info on the mongodb doc for $nor.
How to convert the following hql to Criteria API
var criteria = this.Session.CreateQuery("select m, m.Attachments.size from AdvanceMessage m");
?
Thanks
Your question is a little bit vague but it's something like this :
IList<AdvanceMessage> list = session.CreateCriteria(typeof(AdvanceMessage))
.List<AdvanceMessage>();
