I've downloaded the geonames data dump
The main table has admin3 and admin4 columns but there is no data dump which corresponds to the data in these columns.
Does any one know how to map the admin3 and admin4 codes with their respective place names?
Documentation on the primary website does not seem to explain this but here you go:
select t4.name as town,
t3.name as county,
t2.name as district,
t1.name as admin1,
t0.name,
t0.feature_class,
t0.feature_code,
t0.country_code,
t0.admin1,
t0.admin2,
t0.admin3,
t0.admin4,
t0.population
from geoname t0
left join geoname t1 on t1.admin1 = t0.admin1 and t1.feature_code = 'ADM1'
left join geoname t2 on t2.admin2 = t0.admin2 and t2.feature_code = 'ADM2'
left join geoname t3 on t3.admin3 = t0.admin3 and t3.feature_code = 'ADM3'
left join geoname t4 on t4.admin4 = t0.admin4 and t4.feature_code = 'ADM4'
where t0.name = 'London'

I am looking for a way to perform this query in DQL :
SELECT
t0_.product, t0_.creation_date, t0_.id pvId,
t0_.product AS product,
t0_.file_path AS file_path_3,
t0_.product AS product_11
FROM table0 t0_
join (
select max(creation_date) as createdDate, id, product
from table0
group by product
) t0b on (t0b.createdDate = t0_.creation_date and t0_.product = t0b.product)
LEFT JOIN table1 t1_ ON t0_.product = t1_.id
LEFT JOIN table2 t2_ ON t1_.id = t2_.otherId
LEFT JOIN table3 t3_ ON t2_.id = t3_.otherId
LEFT JOIN table4 t4_ ON t2_.id = t4_.otherId
LEFT JOIN table5 t5_ ON t4_.id = t5_.otherId
LEFT JOIN table6 t6_ ON t4_.id = t6_.otherId
LEFT JOIN table7 t7_ ON t6_.id = t7_.otherId
WHERE t6_.id = :identifier
GROUP BY p0_.product;
explication : I have in table 'table0' several rows linked to table 'table1', I want to keep only the most recent one (column creation_date)
tableA.ID
tableA.propertyTableB.ID
tableA.createdAt

I need to keep the rows : 4, 5, 8,
I need to get a queryBuilder object in order to do other operations behind it.
Has anyone already succeeded in this feat?
Thanks in advance <3
I need to keep the most recents rows from tableA related to tableB
EDIT : Maybe I find another way
no Select in the Join, just another JOIN like this :
FROM table0 t0
LEFT JOIN table0Bis AS t0B ON t0B.identifier = t0.identifier AND t0B.creation_date > t0.creation_date
LEFT JOIN table1 t1 ON t1.id = t0.foo
LEFT JOIN table2 t2 ON t1.id = t2.bar
LEFT JOIN table3 t3 ON t2.id = t3.rab
LEFT JOIN table4 t4 ON t2.id = t4.oof
LEFT JOIN table5 t5 ON t5.id = t4.toto
LEFT JOIN table6 t6 ON t5.id = t6.lorem
LEFT JOIN table7 t7 ON t6.id = t7.ipsum
where t7.id = :id AND t0B.creation_date IS NULL
group by t0.product;
$queryBuilder = $this->createQueryBuilder('t0');
$queryBuilder->leftJoin(
'App\Entity\Table0',
't0b',
Join::WITH,
't0b.product = t0.product AND t0b.creationDate > t0.creationDate')
->leftJoin('t0.foo', 't1')
->leftJoin('t1.bar', 't2')
->leftJoin('t2.bar', 't3')
->leftJoin('t3.rab', 't4')
->andWhere('t4.id = :ident')->setParameter('ident', $user->getId())
->andWhere('t0b.creationDate IS NULL')
->groupBy('t0.id', 't0.foobar')
->orderBy('t0.foobar', 'DESC')

I have two instances of the same database from different days. All tables from one day are called tableA* and from the other tableB*. I would like to compare data to see what have changed. I would like to select all rows that don't match exactly. So for example if one value is different in tables tableA1 and tableB1 I would like to select a corresponding row from table A and mark it as 'new' and from table B and mark it as 'deleted'. I tried with a query like this:
SELECT 'new', ta1.name, ta2.name, ta3.name, ta4.name, ta5.name
FROM tableA1 ta1
LEFT JOIN tableA2 ta2 ON ta1.ta2_id = ta2.id
LEFT JOIN tableA3 ta3 ON ta1.ta3_id = ta3.id
LEFT JOIN tableA4 ta4 ON ta1.ta4_id = ta4.id
LEFT JOIN tableA5 ta5 ON ta5.ta1_id = ta1.id WHERE NOT EXISTS
(SELECT tb1.name, tb2.name, tb3.name, tb4.name, tb5.name
FROM tableB1 tb1
LEFT JOIN tableB2 tb2 ON tb1.tb2_id = tb2.id
LEFT JOIN tableB3 tb3 ON tb1.tb3_id = tb3.id
LEFT JOIN tableB4 tb4 ON tb1.tb4_id = tb4.id
LEFT JOIN tableB5 tb5 ON tb5.tb1_id = tb1.id WHERE
tb1.name = ta1.name AND
tb2.name = ta2.name AND
tb3.name = ta3.name AND
tb4.name = ta4.name AND
tb5.name = ta5.name)
UNION
SELECT 'deleted', tb1.name, tb2.name, tb3.name, tb4.name, tb5.name
FROM tableB1 tb1
LEFT JOIN tableB2 tb2 ON tb1.tb2_id = tb2.id
LEFT JOIN tableB3 tb3 ON tb1.tb3_id = tb3.id
LEFT JOIN tableB4 tb4 ON tb1.tb4_id = tb4.id
LEFT JOIN tableB5 tb5 ON tb5.tb1_id = tb1.id WHERE NOT EXISTS
(SELECT ta1.name, ta2.name, ta3.name, ta4.name, ta5.name
FROM tableA1 ta1
LEFT JOIN tableA2 ta2 ON ta1.ta2_id = ta2.id
LEFT JOIN tableA3 ta3 ON ta1.ta3_id = ta3.id
LEFT JOIN tableA4 ta4 ON ta1.ta4_id = ta4.id
LEFT JOIN tableA5 ta5 ON ta5.ta1_id = ta1.id WHERE
tb1.name = ta1.name AND
tb2.name = ta2.name AND
tb3.name = ta3.name AND
tb4.name = ta4.name AND
tb5.name = ta5.name)
Hoping that if I created the same stuructre and compare all the values I would get the anticipated result. Even if databases are the same I get a lot row selected.
Found the problem. When comparing two NULL values the result is FALSE, the query itself should be fine. So I should have added conditions to check whether values are NULL.
I have two tables table1 and table2. Each table contains a column with itemPrice. I need to add the two columns together.
The SQL query below returns the correct SUM.
SELECT SUM(item1+ item2) FROM
(select SUM(t1.itemPrice) item1 from table1 t1 WHERE t1.userid=='jonh') tableA
CROSS JOIN
(select SUM(t2.itemPrice) item2 from table2 t2 WHERE t1.userid=='jonh') tableB
I am not been lazy but the above query has so many SUM functions that I don't know where to start to write LINQ queries.
Can anyone help?
Ceci,
Hopefully this will give you what you want...
from f in (
from x in ( from t1 in Table1
where t1.Userid.Equals("John")
select new { Userid = t1.Userid }
).Distinct()
select new { item1 = ( from z in Table1
where z.Userid.Equals("John")
select z.ItemPrice ).Sum() ??0 ,
item2 = ( from z in Table2
where z.Userid.Equals("John")
select z.ItemPrice ).Sum() ??0 }
) select new { total = f.item1 + f.item2 }
In the case where there are no records for "john" in one table, it will bring back a 0 and sum up the other tables.
hope this helps.
I have multiple tables in a join and every table has a column ID. So in the resultig join there are a lot of ID columns. How I can access a specific ID column with the criteria API?
ParameterExpression<A> idParam = criteriaBuilder.parameter(A.class, PARAM_NAME);
Subquery<B> sq = query.subquery(B.class);
Root<B> root = sq.from(B.class);
Join<C, D> joinTogether = root.join("memberX").join("memberY");
sq.select(root);
sq.where(criteriaBuilder.and(criteriaBuilder.equal(joinTogether.get("id"), idParam), criteriaBuilder.equal(parentQuery.get("id"), root.get("id"))));
The problem is, that in the resulting SQL contains
SELECT 1 FROM E t6, B t5, C t4, D t3 WHERE ((( = paramName) AND (t0.ID = t5.ID)) AND (((t6.memberZ = t5.ID) AND (t4.ID = t6.memberX)) AND (t3.ID = t4.memberY))))
The table E (t6) is an additional join table between table B and C, t0 is the reference to the parent query. Instead t3.id = :paramName EclipseLink creates nothing just before the first equal-sign (paramName is the content of the constant PARAM_NAME). My idea is, that the "id" column could reference all tables and EclipseLink can not decide, which table I mean.
How I can change that?
Thank you
André
My Stored Procedure takes a very long time to execute.
Can anyone suggest me what I can do to speed up the stored procedure, apart from using some good practices for writing down the queries.
I've heard about creating indices, but I'm not sure what are they.
Please suggest all the best ways to speed up my queries.
Thanks

Here are a few:
You should have indexes for every column in a WHERE clause. See
your SQL language for how to do it.
Learn how to EXPLAIN PLAN and see what's slow.
Stored procedure languages are functional, not set based. Use JOIN and don't fall into the (n+1) query/iteration trap.
Understand how using certain functions force you to TABLE SCAN in a WHERE clause.
