code downstairs will perfom query like this
SELECT anrede FROM `l_anrede` INNER JOIN `person` ON `l_anrede`.id = `person`.id_anrede
But I need a query like this:
SELECT anrede FROM `l_anrede` INNER JOIN `person` ON `l_anrede`.id=`person`.id_anrede WHERE
person.id IN(SELECT id_person FROM bewerber WHERE person.id=bewerber.id);
Any ideas how to round out this code:
$query = LAnrede::find();
/*
$subQuery = Bewerber::find()->select(['id_person'])
->from('bewerber')->where('person.id= bewerber.id');*/
$query->select('anrede')->from('l_anrede')->innerJoin('Person', 'l_anrede.id = person.id_anrede');
var_dump($query->one());
You don't have to use ->from('l_anrede') if youre calling LAnrede::find() - query will select data from table associated with your model. To use subquery in where() method, try like this:
$query->andWhere(['person.id' => $subQuery]);

I have a query and am using left joins. I have the left join clause as follows:
left outer join ( select pup.brokerage_code, pcz.zip, count (pup.aggregate_id) as VerifiedAgentCount
from partner_user_profiles pup
join partner_user_roles pure on pure.user_profile_id = pup.id
join profile_coverage_zips pcz on pcz.profile_id = pup.id
where lower(pure.role) = 'agent'
and pup.verification_status like 'Verified%'
group by pup.brokerage_code, pcz.zip) vac on vac.brokerage_code = b.brokerage_code and pcz.zip = bcz.zip
However I am getting the error message saying that I am missing the FROM entry clause for "pcz" however I aliased the table in the join clause so I am not sure what is wrong.
You have defined the table alias pcz within the sub-select however the alias no longer exists when the outside the sub-select. At the point you have used it the appropriate alias is the one for the entire sub-select, in this case vac. So: vac.zip = = bcz.zip
left outer join ( select pup.brokerage_code, pcz.zip, count (pup.aggregate_id) as VerifiedAgentCount
from partner_user_profiles pup
join partner_user_roles pure on pure.user_profile_id = pup.id
join profile_coverage_zips pcz on pcz.profile_id = pup.id
where lower(pure.role) = 'agent'
and pup.verification_status like 'Verified%'
group by pup.brokerage_code, pcz.zip
) vac on vac.brokerage_code = b.brokerage_code
and vac.zip = bcz.zip
I want to rewrite the following query using jooq:
with first_temp as (
select a.id as lie_id
from first_table a
where a.some_Field = 100160
), second_temp as (
select b.id as ben_id
from second_table b
where b.email = 'some.email#gmail.com'
) insert into third_table (first_table_id, second_table_id)
select a.lie_id, b.ben_id from first_temp a, second_temp b;
I was trying something like the following:
DriverManager.getConnection(url, login, password).use {
val create = DSL.using(it, SQLDialect.POSTGRES)
create.with("first_temp").`as`(create.select(FIRST_TABLE.ID.`as`("lie_id")))
.with("second_temp").`as`(create.select(SECOND_TABLE.ID.`as`("ben_id")))
.insertInto(THIRD_TABLE, THIRD_TABLE.FIRST_TABLE_ID, THIRD_TABLE.SECOND_TABLE_ID)
.select(create.select().from("first_temp", "second_temp"), create.select().from("second_temp")))
}
But without success.
Your fixed query
// You forgot FROM and WHERE clauses in your CTEs!
create.with("first_temp").`as`(
create.select(FIRST_TABLE.ID.`as`("lie_id"))
.from(FIRST_TABLE)
.where(FIRST_TABLE.SOME_FIELD.eq(100160)))
.with("second_temp").`as`(
create.select(SECOND_TABLE.ID.`as`("ben_id"))
.from(SECOND_TABLE)
.where(SECOND_TABLE.EMAIL.eq("some.email#gmail.com")))
.insertInto(THIRD_TABLE, THIRD_TABLE.FIRST_TABLE_ID, THIRD_TABLE.SECOND_TABLE_ID)
// You had too many queries in this part of the statement, and
// didn't project the two columns you were interested int
.select(create.select(
field(name("first_temp", "lie_id")),
field(name("second_temp", "ben_id")))
.from("first_temp", "second_temp"))
// Don't forget this ;-)
.execute();
But frankly, why even use CTE at all? Your query would be much simpler like this, both in SQL and in jOOQ (assuming that you really want this cartesian product):
Better SQL Version
insert into third_table (first_table_id, second_table_id)
select a.id, b.id
from first_table a, second_table b
where a.some_field = 100160
and b.email = 'some.email#gmail.com';
Better jOOQ Version
create.insertInto(THIRD_TABLE, THIRD_TABLE.FIRST_TABLE_ID, THIRD_TABLE.SECOND_TABLE_ID)
.select(create.select(FIRST_TABLE.ID, SECOND_TABLE.ID)
.from(FIRST_TABLE, SECOND_TABLE)
.where(FIRST_TABLE.SOME_FIELD.eq(100160))
.and(SECOND_TABLE.EMAIL.eq("some_email#gmail.com")))

I need to implement the following T-SQL clause ....
SELECT
CONCAT( RANK() OVER (ORDER BY [Order].codOrder, [PackedOrder].codPackedProduct ), '/2') as Item,
[Order].codOrder as [OF],
[PackedOrder].codLine as [Ligne],
[PackedOrder].codPackedProduct as [Material], ----------------------
[Product].lblPProduct as [Product],
[PackedProduct].lblPackedProduct as [MaterialDescription],
[PackedOrder].codPackedBatch as [Lot],
[Product].codCustomerColor as [ReferenceClient],
[PackedOrder].nbrPackedQuantity as [Quantity],
[PackedOrder].nbrLabelToPrint as [DejaImprime]
FROM [Order] INNER JOIN PackedOrder
ON [Order].codOrder = PackedOrder.codOrder INNER JOIN Product
ON [Order].codProduct = Product.codProduct INNER JOIN PackedProduct
ON PackedOrder.codPackedProduct = PackedProduct.codPackedProduct
Where [Order].codOrder = 708243075
So Far, I'm able to do:
var result =
from order1 in Orders
join packedorder1 in PackedOrders on order1.codOrder equals packedorder1.codOrder
join product1 in Products on order1.codProduct equals product1.codProduct
join packedproduct1 in PackedProducts on packedorder1.codPackedProduct equals packedproduct1.codPackedProduct
where order1.codOrder == _order.codOrder
select new FinishedProductPrintingM
{
OF = order1.codOrder,
Ligne = packedorder1.codLine,
Material = packedorder1.codPackedProduct,
Produit = product1.codProductType,
MaterialDescription = packedproduct1.lblPackedProduct,
Lot = packedorder1.codPackedBatch,
RéférenceClient = product1.codCustomerColor,
Quantité = packedorder1.nbrPackedQuantity,
Déjàimprimé = packedorder1.nbrLabelPrinted
};
Please let me know if its possible or not. I need to display the Items in such a way.Please feel free to add your valuable comments.
I am not aware how to use concat and Rank over function in LINQ.
Can anyone help me to convert my SQL query into LINQ?
Suppose I have an activity table and a subscription table. Each activity has an array of generic references to some other object, and each subscription has a single generic reference to some other object in the same set.
CREATE TABLE activity (
id serial primary key,
ob_refs UUID[] not null
);
CREATE TABLE subscription (
id UUID primary key,
ob_ref UUID,
subscribed boolean not null
);
I want to join with the set-returning function unnest so I can find the "deepest" matching subscription, something like this:
SELECT id
FROM (
SELECT DISTINCT ON (activity.id)
activity.id,
x.ob_ref, x.ob_depth,
subscription.subscribed IS NULL OR subscription.subscribed = TRUE
AS subscribed,
FROM activity
LEFT JOIN subscription
ON activity.ob_refs #> array[subscription.ob_ref]
LEFT JOIN unnest(activity.ob_refs)
WITH ORDINALITY AS x(ob_ref, ob_depth)
ON subscription.ob_ref = x.ob_ref
ORDER BY x.ob_depth DESC
) sub
WHERE subscribed = TRUE;
But I can't figure out how to do that second join and get access to the columns. I've tried creating a FromClause like this:
act_ref_t = (sa.select(
[sa.column('unnest', UUID).label('ob_ref'),
sa.column('ordinality', sa.Integer).label('ob_depth')],
from_obj=sa.func.unnest(Activity.ob_refs))
.suffix_with('WITH ORDINALITY')
.alias('act_ref_t'))
...
query = (query
.outerjoin(
act_ref_t,
Subscription.ob_ref == act_ref_t.c.ob_ref))
.order_by(activity.id, act_ref_t.ob_depth)
But that results in this SQL with another subquery:
LEFT OUTER JOIN (
SELECT unnest AS ob_ref, ordinality AS ref_i
FROM unnest(activity.ob_refs) WITH ORDINALITY
) AS act_ref_t
ON subscription.ob_refs #> ARRAY[act_ref_t.ob_ref]
... which fails because of the missing and unsupported LATERAL keyword:
There is an entry for table "activity", but it cannot be referenced from this part of the query.
So, how can I create a JOIN clause for this SRF without using a subquery? Or is there something else I'm missing?
Edit 1 Using sa.text with TextClause.columns instead of sa.select gets me a lot closer:
act_ref_t = (sa.sql.text(
"unnest(activity.ob_refs) WITH ORDINALITY")
.columns(sa.column('unnest', UUID),
sa.column('ordinality', sa.Integer))
.alias('act_ref'))
But the resulting SQL fails because it wraps the clause in parentheses:
LEFT OUTER JOIN (unnest(activity.ob_refs) WITH ORDINALITY)
AS act_ref ON subscription.ob_ref = act_ref.unnest
The error is syntax error at or near ")". Can I get TextAsFrom to not be wrapped in parentheses?
It turns out this is not directly supported by SA, but the correct behaviour can be achieved with a ColumnClause and a FunctionElement. First import this recipe as described by zzzeek in this SA issue. Then create a special unnest function that includes the WITH ORDINALITY modifier:
class unnest_func(ColumnFunction):
name = 'unnest'
column_names = ['unnest', 'ordinality']
#compiles(unnest_func)
def _compile_unnest_func(element, compiler, **kw):
return compiler.visit_function(element, **kw) + " WITH ORDINALITY"
You can then use it in joins, ordering, etc. like this:
act_ref = unnest_func(Activity.ob_refs)
query = (query
.add_columns(act_ref.c.unnest, act_ref.c.ordinality)
.outerjoin(act_ref, sa.true())
.outerjoin(Subscription, Subscription.ob_ref == act_ref.c.unnest)
.order_by(act_ref.c.ordinality.desc()))
When I run the selects below, I do not get Field3 in the result set, why?
Select
a.Field1,
a.Field2,
a.Field3,
sum(IsNull(a.Field4, 0)) AS SomeAlias1,
a.SomeField5,
a.SomeField6,
a.SomeField7
From SomeTable a
INNER JOIN SomeView1 v on v.au = a.au
inner join (select Username, House from Users userBuildings where UserName = #UserName) as userHouses on userHouses.au = a.au
WHERE
(((where claus logic here....
Group BY a.Field1,
a.Field2,
a.SomeAlias1,
a.Field3,
a.Field4,
a.Field5,
a.Field6,
a.Fielf7
)
Select
transBudget.Field1,
transBudget.Field2,
transDiscount.Field4,
... some other fields...
IsNull(transDiscount.Actual, 0) - IsNull(transBudget.Actual, 0) AS Variance
from (Select * from Transactdions Where TransDesc = 'Budget') AS transBudget
FULL OUTER JOIN
(Select * from Transactions Where TransDesc = 'Discount') AS transDiscount
ON transBudget.Market = transDiscount.Market AND transBudget.SubMarket = transDiscount.SubMarket
I see every field except Field3 for some reason and it's beyond me how the heck this can happen.
In the second part of your query, you are missing field 3.
Select
transBudget.Field1,
transBudget.Field2,
transDiscount.Field4,
... some other fields...
IsNull(transDiscount.Actual, 0)
You appear to have two separate SQL queries there. The first one contains Field3, but the second one does not.
