Querying through java

I have two tables: harvested_record and harvested_record_simple_keys there are in relation one-to-one.
harvested_record
id|harvested_record_simple_keys_id|a lot of columns
harvested_record_simple_keys
id| a lot of columns
and I want to make a query in which I need to join there two tables. As a result I will have a table:
joined_table
id(harvested_record)| (harvested_record_simple_keys)|a lot of columns.
Unfortunately I get an exception: nested exception is java.sql.SQLSyntaxErrorException: Column name 'ID' matches more than one result column.
I've understood this is because after join I will have two columns 'id'. Does anyone can help me with solution?
P.S.
SQL statement(works in IDEA console):
SELECT * FROM ( SELECT TMP_ORDERED.*, ROW_NUMBER() OVER () AS ROW_NUMBER FROM (SELECT * FROM harvested_record hr JOIN harvested_record_simple_keys hrsk ON hrsk.id = hr.harvested_record_simple_keys_id WHERE import_conf_id = ? ) AS TMP_ORDERED) AS TMP_SUB WHERE TMP_SUB.ROW_NUMBER <= 2 ORDER BY import_conf_id ASC, record_id ASC;
Java code(suppose error is here):
JdbcPagingItemReader<HarvestedRecord> reader = new JdbcPagingItemReader<HarvestedRecord>();
SqlPagingQueryProviderFactoryBean pqpf = new SqlPagingQueryProviderFactoryBean();
pqpf.setDataSource(dataSource);
pqpf.setSelectClause("SELECT *");
pqpf.setFromClause("FROM harvested_record hr JOIN harvested_record_simple_keys hrsk ON hrsk.id = hr.harvested_record_simple_keys_id");
String whereClause = "WHERE import_conf_id = :configId";
if (from!=null) {
fromStamp = new Timestamp(from.getTime());
whereClause += " AND updated >= :from";
}
if (to!=null) {
toStamp = new Timestamp(to.getTime());
whereClause += " AND updated <= :to";
}
if (configId != null) {
pqpf.setWhereClause(whereClause);
}
pqpf.setSortKeys(ImmutableMap.of("import_conf_id",
Order.ASCENDING, "record_id", Order.ASCENDING));
reader.setRowMapper(harvestedRecordRowMapper);
reader.setPageSize(PAGE_SIZE);
reader.setQueryProvider(pqpf.getObject());
reader.setDataSource(dataSource);
if (configId != null) {
Map<String, Object> parameterValues = new HashMap<String, Object>();
parameterValues.put("configId", configId);
parameterValues.put("from", fromStamp );
parameterValues.put("to", toStamp);
reader.setParameterValues(parameterValues);
}
reader.afterPropertiesSet();
Thank you in advance.

If you name your columns in the select statement instead of using 'SELECT *', you can omit the ID from one of the tables since it is always equal to the id from the other table.

getting data from result set is too slow

Fetching data from PostgreSQL database with Result Set is too slow.
Here is my code.
for (int i = 0; i < qry_list.size(); i++) {
try {
resultSet = statement.executeQuery(qry_list.get(i));
resultSet.setFetchSize(0);
while (resultSet.next()) {
totalfilecrated = totalfilecrated
+ resultSet.getInt(columnname);
}
} catch (SQLException e) {
e.printStackTrace();
}
}
Here I try to fetch data inside a for loop.is it good?
Here is my query.
For getting ID of individual Organisations(org_unit_id).
"select org_unit_id from emd.emd_org_unit where org_unit_id
in(select org_unit_id from emd.emd_org_unit_detail where entity_type_id=1 and is_active=true) and
is_active=true order by org_unit_name_en";
Then i want to get the count of files with each org_unit_id
select count(*) as totalfilecreatedelectronic from fl_file ff
left join vw_employee_details_with_department epd on epd.post_detail_id=ff.file_opened_by_post_fk
where ff.file_nature = 'E' and ((ff.migration_date>='2011-01-01' and ff.migration_date<='2015-01-01') or
(ff.opening_date >='2011-01-01' and ff.opening_date <='2015-01-01')) and
epd.departmentid=org_unit_id";

Seeing how your second query already contains a reference to a column that's an org_unit_id, you might think joining emd_org_unit table in directly:
select org.org_unit_id, count(*) as totalfilecreatedelectronic
from fl_file ff
left join vw_employee_details_with_department epd on epd.post_detail_id=ff.file_opened_by_post_fk
-- join to active entries in emd_org_unit
inner join from emd.emd_org_unit org ON epd.departmentid=org.org_unit_id
AND org.is_active=true
where ff.file_nature = 'E'
and (
(ff.migration_date>='2011-01-01' and ff.migration_date<='2015-01-01') or
(ff.opening_date >='2011-01-01' and ff.opening_date <='2015-01-01'))
-- and now group by org_unit_id to get the counts
group by org_unit_id
If you'd create a SQLFiddle for this, things would get much clearer I guess.

Convert mysql query to JPQL query

How can i state the following mysql query in JPQL
select * from Price WHERE `valueDate` = (SELECT MAX(`valueDate`) FROM Price) and fundId = 2930
what i have tried is the following:
"select a from Price a where a.valueDate = select MAX(a.valueDate) and a.fund.id = :" +Price.QUERY_PARAM_FUND_ID
but get errors on that approach :
Caused by: <openjpa-2.3.0-r422266:1540826 nonfatal user error> org.apache.openjpa.persistence.ArgumentException: "Encountered "MAX" at character 50, but expected: ["AND", "GROUP", "HAVING", "OR", "ORDER", <EOF>]." while parsing JPQL "select a from Price a where a.valueDate = select MAX(b.valueDate) from Price b and a.fund.id = :fundId"

I think it will work if you will added bracket before and after sub-query like.
"select a from Price a where a.valueDate = (select MAX(a.valueDate) from Price) and a.fund.id = :" +Price.QUERY_PARAM_FUND_ID
else let me say some thing related to hibernate implementation of JPA Specification.
If you have Hibernate model named 'Price' and you are going to do query through that model then. the HQL will be like that
try {
final StringBuilder qry = new StringBuilder();
qry.append(" SELECT")
.append(" FROM Price p")
.append(" WHERE p.valueDate = (SELECT MAX(pr.valueDate) FROM Price pr)")
.append(" AND p.fundId = :fundId");
return getJpaTemplate().execute(new JpaCallback() {
public Object doInJpa(EntityManager em)
throws PersistenceException {
Query q = em.createQuery(qry.toString());
q.setParameter("fundId", fundId);
return q.getResultList();
}
});
} catch (RuntimeException re) {}

JDBC Error (SQL syntax) Parameter index out of range (2 > number of parameters, which is 1) [duplicate]

This question already has answers here:
java.sql.SQLException Parameter index out of range (1 > number of parameters, which is 0) [closed]

Closed 6 years ago.
Im getting this unkown error when running this code:
String SELECT_getWhenValueChanged = "SELECT a.* FROM status AS a WHERE a.value <> (SELECT b.value FROM status AS b WHERE a.idCategory = ? AND b.idCategory = a.idCategory and a.timeStamp > b.timeStamp ORDER BY b.timeStamp DESC LIMIT 1) ORDER BY timeStamp DESC";
try {
Survey surveyTemp = new Survey();
surveyTemp = (Survey) getJdbcTemplate()
.queryForObject(SELECT_getWhenValueChanged,
new Object[] { categoryId, categoryId },
new SurveyMapper());
/*
* SQL Question ask when the value has changed and get the value
* that changed from and changed to, the first one is the current
* value and the second is the value before it changed
*/
if (!surveyTemp.getTimestamp().isEmpty()
&& !presentSurvey.getTimestamp().isEmpty()) {
presentSurvey.setTimestamp(surveyTemp.getTimestamp());
}
} catch (BadSqlGrammarException e) {
e.printStackTrace();
} catch (EmptyResultDataAccessException e) {
} catch (Exception e) {
e.printStackTrace();
}
return presentSurvey;
Anybody know what this means?
org.springframework.dao.TransientDataAccessResourceException: PreparedStatementCallback; SQL [SELECT a.* FROM status AS a WHERE a.value <> (SELECT b.value FROM status AS b WHERE a.idCategory = ? AND b.idCategory = a.idCategory and a.timeStamp > b.timeStamp ORDER BY b.timeStamp DESC LIMIT 1) ORDER BY timeStamp DESC]; Parameter index out of range (2 > number of parameters, which is 1).; nested exception is java.sql.SQLException: Parameter index out of range (2 > number of parameters, which is 1).
Im not good at SQL, so dont know how to solve this...

Since there is only one parameter in your PreparedStatement, you should not pass two parameters into it. Maybe you can change new Object[] { categoryId, categoryId } into new Object[] { categoryId }.

changed it to
String SELECT_getWhenValueChanged = "SELECT a.* FROM status AS a WHERE a.idCategory = ? AND a.value = ? AND a.timeStamp > (SELECT b.timeStamp FROM status AS b WHERE b.idCategory = ? and b.value <> ? ORDER BY timeStamp DESC LIMIT 1) ORDER BY timeStamp ASC LIMIT 1";
try {
Survey surveyTemp = (Survey) getJdbcTemplate().queryForObject(SELECT_getWhenValueChanged,
new Object[] { categoryId, presentSurvey.getValue(), categoryId, presentSurvey.getValue() },
new SurveyMapper());
And that worked! thanks

// In Spring DAO Module using On that time these Exception is raised
// Correct Code
public StudentRegistrationBean select(int studentId) {
StudentRegistrationBean queryForObject = jdbcTemplate.queryForObject(
"SELECT * FROM STUDENTREGISTRATION WHERE STUDENTID=?", new Object[] { studentId },
new BeanPropertyRowMapper<StudentRegistrationBean>(
StudentRegistrationBean.class));
return queryForObject;
// Wrong Code
public StudentRegistrationBean select(int studentId) {
StudentRegistrationBean queryForObject = jdbcTemplate.queryForObject(
"SELECT * FROM STUDENTREGISTRATION WHERE STUDENTID=?", new Object[] { studentId },
new BeanPropertyRowMapper<StudentRegistrationBean>(
StudentRegistrationBean.class));
return null;
Conclusion: if you are retuning values you might mistake in put "null" type of values... Means Some thing Make Mistake Methods Writing (OR) return null values

getting error that nested exception is org.hibernate.hql.ast.QuerySyntaxException: Path expected for join

I am new to hibernate and I have a query
select * from Losa_App a
inner join
os_historystep os
on
a.app_ref_no = os.ref_id
where
os.step_name = '011' and app_status = 'R' or app_status = 'S' ;
when i run this query on sqldeveloper it runs and give me the results. Now i translated the query into HBL like
StringBuffer query = new StringBuffer();
List<String> lstObj = new ArrayList<String>();
query.append(" from ");
query.append(getClassName());
query.append(" a inner join "
// + WflWorkflowHistoryStep.class.getName()
+ " OS_HISTORYSTEP os with a.appRefNo = os.ref_id "
+ "where os.step_name = '011' and a.appStatus = 'R' or a.appStatus = 'S' ");
List<LosaApp> result = null;
try {
result = getHibernateTemplate().find(query.toString());
if (CollectionUtils.isNotEmpty(result) {
return result;
}
} catch (Exception e) {
String message = e.getMessage();
System.out.println();
}
return null;
But when this query runs i get exception that
nested exception is org.hibernate.hql.ast.QuerySyntaxException: Path expected for
join! [ from com.thetasp.losa.data.LosaApp a inner join OS_HISTORYSTEP os with
a.appRefNo = os.ref_id where os.step_name = '011' and a.appStatus = 'R'
or a.appStatus = 'S' ]
Why i am getting this error ?
Thanks

Your HQL syntax is wrong.
You need to specify the alias by using the keyword as. E.g:- Losa_App as a
If you give inner join, and have your association mappings done, then you needn't provide the on clause.
If you want to give a.app_ref_no = os.ref_id, then you need not specify inner join. Hibernate will take care of that.
For more info, do have a look at this question.
