My table looks something like this:
I want to retrieve all the PractitionerIdFK if they have SpecialityIdFK = 1 AND SpecialityIdFK= 2. I tried the following but it doesn't seem to work.
SELECT PractitionerSpecialities.PractitionerIdFK
FROM PractitionerSpecialities
WHERE PractitionerSpecialities.SpecialityIdFK IN (
SELECT PractitionerSpecialities.SpecialityIdFK
FROM PractitionerSpecialities
WHERE PractitionerSpecialities.SpecialityIdFK = 1
AND PractitionerSpecialities.SpecialityIdFK = 2
)
You can use GROUP BY and HAVING:
SELECT ps.PractitionerIdFK
FROM PractitionerSpecialities ps
WHERE ps.SpecialityIdFK IN (1, 2)
GROUP BY ps.PractitionerIdFK
HAVING COUNT(*) = 2; -- the size of the comparison list
This assumes that there are no duplicates in PractitionerSpecialities. If that is a possibility, then use HAVING COUNT(DISTINCT ps.SpecialityIdFK) = 2.
It can be achieved by using IN and BETWEEN operator in SQL .
SELECT PractitionerSpecialities.PractitionerIdFK
FROM PractitionerSpecialities
WHERE PractitionerSpecialities.SpecialityIdFK in (1,2)
-- You can BETWEEN Clause as well ..
SELECT PractitionerSpecialities.PractitionerIdFK
FROM PractitionerSpecialities
WHERE PractitionerSpecialities.SpecialityIdFK BETWEEN 1 AND 2
In Sub query use OR operator instead of AND .

I have an oracle query as follows but when I make changes to pagination the results are different. what should i pass for my code
SELECT *
FROM (
SELECT b.*,
ROWNUM r__
FROM (
select a.KODE_KLAIM,
a.NO_SS,
a.LA,
a.NAMA_TK,
a.KODE_K,
(
select tk.TEM_LAHIR
from KN.VW_KN_TK tk
where tk.KODE_K = a.KODE_K and rownum=1
) TEM_LAHIR,
(
select TO_CHAR(tk.TLAHIR, 'DD/MM/RRRR')
from KN.VW_KTK tk
where tk.KODE_K = a.KODE_K
and rownum=1
) TLAHIR
from PN.KLAIM a
where nvl(a.STATUS_BATAL,'X') = 'T'
and A.NOMOR IS NOT NULL
and A.TIPE_KLAIM = 'JPN01'
)b
)
where 1 = 1
WHERE ROWNUM < ( ( ? * ? ) + 1 )
WHERE r__ >= ( ( ( ? - 1 ) * ? ) + 1 )
but i run this query i have result ORA-00900: invalid SQL statement
You have three WHERE clauses at the end (and no ORDER BY clause). To make it syntactically valid you could change the second and third WHERE clauses to AND.
However, you mention pagination so what you probably want is to use:
SELECT *
FROM (
SELECT b.*,
ROWNUM r__
FROM (
select ...
from ...
ORDER BY something
)b
WHERE ROWNUM < :page_size * :page_number + 1
)
WHERE r__ >= ( :page_number - 1 ) * :page_size + 1
Note: You can replace the named bind variables with anonymous bind variables if you want.
Or, if you are using Oracle 12 or later then you can use the OFFSET x ROWS FETCH FIRST y ROWS ONLY syntax:
select ...
from ...
ORDER BY something
OFFSET (:page_number - 1) * :page_size ROWS
FETCH FIRST :page_size ROWS ONLY;
Additionally, you have several correlated sub-queries such as:
select tk.TEM_LAHIR
from KN.VW_KN_TK tk
where tk.KODE_K = a.KODE_K and rownum=1
This will find the first matching row that the SQL engine happens to read from the datafile and is effectively finding a random row. If you want a specific row then you need an ORDER BY clause and you need to filter using ROWNUM AFTER the ORDER BY clause has been applied.
From Oracle 12, the correlated sub-query would be:
select tk.TEM_LAHIR
from KN.VW_KN_TK tk
where tk.KODE_K = a.KODE_K
ORDER BY something
FETCH FIRST ROW ONLY
hey guys this is a very simple sql query that is not giving me the correct result.
subquery:
SELECT NEODB2ADMIN.ORDERS.MEMBER_ID
FROM NEODB2ADMIN.ORDERS
WHERE NEODB2ADMIN.ORDERS.ORDERS_ID = 6371043
this subquery successfully returns a correct value 627809
simple query:
SELECT *
FROM NEODB2ADMIN.ADDRESS
WHERE MEMBER_ID IN (627809)
this query executes properly and returns 4 rows.(4 addresses for a member)
but if I try to combine these queries in 1 query as follows:
SELECT *
FROM NEODB2ADMIN.ADDRESS
WHERE MEMBER_ID IN (
SELECT NEODB2ADMIN.ORDERS.MEMBER_ID
FROM NEODB2ADMIN.ORDERS
WHERE NEODB2ADMIN.ORDERS.ORDERS_ID = 6371043
)
then the query returns 0 rows. why is this happening?
Thanks
Your query looks OK, the only I can think is maybe you mistake the value on the result.
can you try this:
SELECT *
FROM NEODB2ADMIN.ADDRESS
WHERE MEMBER_ID IN (
SELECT 627809
FROM NEODB2ADMIN.ORDERS
WHERE NEODB2ADMIN.ORDERS.ORDERS_ID = 6371043
)
and this
SELECT *
FROM NEODB2ADMIN.ADDRESS
WHERE MEMBER_ID IN (
SELECT 627809
FROM NEODB2ADMIN.ORDERS
)
Since your Order (presumably) can only carry a single Member_ID -- can you please try your full query without the "IN", rather try an equal join as follows:
SELECT *
FROM NEODB2ADMIN.ADDRESS
WHERE MEMBER_ID = (
SELECT NEODB2ADMIN.ORDERS.MEMBER_ID
FROM NEODB2ADMIN.ORDERS
WHERE NEODB2ADMIN.ORDERS.ORDERS_ID = 6371043
)
I need to select records that has ID = 10,23,30 so I wrote this SQL
Select * from mytable where position(id in '10,23,30') > 0
But the problem I get additional records where ID = 1 and 2
Any ideas how to select only what I need ?
No need for position, just do IN:
Select * from mytable
where id in (10,23,30)
Use IN operator:
Select * from mytable where id in (10,23,30)
I have a sql query that I run against a sql server database eg.
SELECT * FROM MyTable WHERE Id = 2
This may return a number of records or may return none. If it returns none, I would like to alter my sql query to return a default record, is this possible and if so, how? If records are returned, the default record should not be returned. I cannot update the data so will need to alter the sql query for this.
Another way (you would get an empty initial rowset returned);
SELECT * FROM MyTable WHERE Id = 2
IF (##ROWCOUNT = 0)
SELECT ...
SELECT TOP 1 * FROM (
SELECT ID,1 as Flag FROM MyTable WHERE Id = 2
UNION ALL
SELECT 1,2
) qry
ORDER BY qry.Flag ASC
You can have a look to this post. It is similar to what you are asking
Return a value if no rows are found SQL
I hope that it can guide you to the correct path.
if not exists (SELECT top 1 * FROM mytable WHERE id = 2)
select * from mytable where id= 'whatever_the_default_id_is'
else
select * from mytable where id = 2
If you have to return whole rows of data (and not just a single column) and you have to create a single SQL query then do this:
Left join actual table to defaults single-row table
select
coalesce(a.col1, d.col1) as col1,
coalesce(a.col2, d.col2) as col2,
...
from (
-- your defaults record
select
default1 as col1,
default2 as col2,
...) as d
left join actual as a
on ((1 = 1) /* or any actual table "where" conditions */)
The query need to return the same number of fields, so you shouldn't do a SELECT * FROM but a SELECT value FROM if you want to return a default value.
With that in mind
SELECT value FROM MyTable WHERE Id = 2
UNION
SELECT CASE (SELECT count(*) FROM MyTable WHERE Id = 2)
WHEN 0 THEN 'defaultvalue'
END
i have four queries that return intergers.
select listOfIntegers from [something]...
(edit: the results are ROWS)
and need a way to do
select ...
intersect
select ...
intersect
select ...
intersect
select ...
but in jpql there is no intersect as such.
so, is there a way to mimic the behavior using some other jpql to get the same result?
(for those that are unsure about intersect) basically i need to get all the values that appear in ALL the selects...
result from select 1: 1,2,3,4
result from select 2: 1,2,5,6
result from select 3: 1,2,7,8
result from select 4: 1,2,9,0
so the result i want with intersect: 1,2
thnx a lot
p.s. there is no chance to use ANYHTING OTHER THAN JPQL :( no native queries, etc...
Can you use something like this?:
select s1.result
from select_1 as s1
where exists (
select *
from select_2 as s2
where s2.result = s1.result
)
and exists (
select *
from select_3 as s3
where s3.result = s1.result
)
and exists (
select *
from select_4 as s4
where s4.result = s1.result
);
