How to add date in mysql database from Hibernate/Spring Jpa

I use spring boot, and I want to add 1 year to a specific column in mysql database
String queryRecherche = "UPDATE myTable t SET t.dateDebut = DATE_ADD(t.dateDebut, INTERVAL 1 YEAR) WHERE.id = 3 ";
Query query = em.createQuery(queryRecherche);;
query.executeUpdate();
But I get the folowing error :
org.hibernate.query.sqm.ParsingException: line 1:66 no viable alternative at input 'DATE_ADD(t.dateDebut,INTERVAL1'
Have you please any suggestions to do this.

You're using Hibernate 6 (I can tell by the error message), so the correct HQL syntax to use is:
UPDATE MyEntity t SET t.dateDebut = t.dateDebut + 1 year WHERE t.id = 3
You had three errors in your query:
You referred to the name of a table instead of the name of an entity class in the UPDATE clause.
You used the unportable MySQL DATE_ADD function instead of the portable HQL date/time arithmetic described here.
The syntax of your WHERE clause was garbled.
Perhaps you meant for this to be a native SQL query, in which case you called the wrong method of Session. But there's no need to use native SQL for the above query. As you can see, HQL is perfectly capable of expressing that query.

You can use SQL directly, via createNativeQuery, or register a new function as shown in this example to call it from HQL

Query returning sql string with wrong parameters

I am currently working on fixing some SQL injection bugs in my project.
Here is my current sql string:
String sql = "select * from :table order by storenum";
Here is how I am setting the parameters:
SQLQuery query = sess.createSQLQuery(sql).setParameter("table", table);
(table is a string that is passed in through a method)
Whenever I run the program I get something like this:
select * from ? order by storenum

You can't dynamically bind table names, only values, so you'll have to resort to string manipulation/concatenation to get the table name dynamically. However, you would probably want to escape it to avoid SQL Injections.

Are mutliple statements without transaction possible using jdbcTemplate

I am trying to update 2 tables at the same time where the inserted index of the first should be inserted into the 2nd table.
The sql looks like this:
DECLARE #nrTable table (TXT_nr int)
IF NOT EXISTS (SELECT txt FROM tbl1 WHERE txt = (?))
INSERT INTO tbl1 (txt, new) OUTPUT INSERTED.nr INTO #nrTable VALUES((?), 1)
IF NOT EXISTS (SELECT txt FROM tbl1 WHERE txt =(?))
INSERT INTO tbl2 (TXT_nr, field1, field2)
VALUES((SELECT TXT_nr FROM #nrTable), (?), (?))
WHERE field3 = (?) AND field4 = (?)
I am trying to accomplish this using
this.jdbcTemplate.batchUpdate(sql, batch);
simply concatenating the lines in java using basic strings. This seems to only execute the first statement, though.
Now the reason I don´t want to do this transactionally is that I would have to do it using a loop just inserting one batch-object at a time, because of the ouput-clause. This would result in loads of calls to the sql-server.
Is there any known way to accomplish something like this?

You can't use batchupdate in this way. Please refer to this document http://tutorials.jenkov.com/jdbc/batchupdate.html
And to achieve your goal, if you are using a sequence in sql, then you need to get the new value in java and store it in your query. Like this :
long id = jdbcTemplace.queryForObject("select sequence_name.nextval from dual",Long.class);

jOOQ addConditions: in SQL question mark appears instead of the value

I would like to launch simple code:
SelectQuery query = dsl.select(field ("id"), field("title")).from("dict.models").getQuery();
if (modelId > 0) query.addConditions(field("model_id", SQLDataType.INTEGER).equal(modelId));
But infortunately in getSQL() I can only see:
select id, title from dict.models where model_id = ?
Where is a mistake?
Thanks.

Query.getSQL() generates the SQL statement as it would be generated if you let jOOQ execute a PreparedStatement - with bind variables. The bind variables can be extracted in the right order via Query.getBindValues()
If you want to inline all bind values into the generated SQL, you have various options through the jOOQ API (all equivalent):
Using Query.getSQL(ParamType) with ParamType.INLINE
Using dsl.renderInlined(QueryPart)
Using StatementType.STATIC_STATEMENT in your Settings

How to create sqlite prepared statement in OrmLite?

Is it possible to create a sqlite prepared statement in OrmLite?
If so, how to bind the query values which may change across different queries.

Is it possible to create a sqlite prepared statement in OrmLite?
You need to RTFM since ORMLite's online documentation is pretty extensive. If you look in the index for "prepared statement" you find out about the QueryBuilder which #Egor pointed out.
how to bind the query values which may change across different queries.
A little further in that section you learn about select arguments which is how you bind query values that change across queries. This is in the index under "arguments to queries".
To quote from the docs here's how you prepare a custom query:
QueryBuilder<Account, String> queryBuilder = dao.queryBuilder();
Where<Account, String> where = queryBuilder.where();
SelectArg selectArg = new SelectArg();
// define our query as 'name = ?'
where.eq("name", selectArg);
// prepare it so it is ready for later query or iterator calls
PreparedQuery<Account> preparedQuery = queryBuilder.prepare();
When you are ready to run the query you set the select argument and issue the query:
selectArg.setValue("foo");
List<Account> accounts = dao.query(preparedQuery);
Later, you can set the select argument to another value and re-run the query:
selectArg.setValue("bar");
accounts = accountDao.query(preparedQuery);
