how to i get alias name for my query. Below i am using spring boot with hibernate JPA native query. What i want is to get alias name cbpartnerid as WHERE parameter, because i get c_b_partner from 2 table with condition.
But spring giver me error this :
ERROR 2021-02-26 06:00:02.492 [http-nio-8080-exec-9] o.h.e.jdbc.spi.SqlExceptionHelper.logExceptions(142) - ERROR: column "cbpartnerid" does not exist
i hope can solve this issue without change overall query or modify backend code.
here are my native query :
(CASE
WHEN i.transaction = 'SALES' OR i.transaction = 'CUSTOMER_RETURN' THEN j.c_bpartner_id
WHEN i.transaction = 'INVENTORY_OUT' OR i.transaction = 'INVENTORY_OUT' THEN l.c_bpartner_id
ELSE null
END) AS **cbpartnerid**
FROM so_transaction i
LEFT JOIN so_orderline j ON j.so_orderline_id = i.so_orderline_id LEFT JOIN so_inventoryline k ON k.so_inventoryline_id = i.so_inventoryline_id
LEFT JOIN so_inventory l ON l.so_inventory_id = k.so_inventory_id
GROUP BY i.created, i.transaction, i.m_product_id, i.productname, i.createdby, **cbpartnerid** ORDER BY i.m_product_id DESC ```
The easy solution is a subquery.
Your code, reduced to the essential, looks like
SELECT /* complicated expression */ AS alias,
/* other columns */
FROM atable
GROUP BY alias;
This can be rewritten to
SELECT alias, /* other columns */
FROM (SELECT /* complicated expression */ AS alias,
/* other columns */
FROM atable) AS subq
GROUP BY alias;
SELECT i.created, i.transaction, i.m_product_id, i.productname, i.createdby,
(CASE
WHEN i.transaction = 'SALES' OR i.transaction = 'CUSTOMER_RETURN' THEN j.c_bpartner_id
WHEN i.transaction = 'INVENTORY_OUT' OR i.transaction = 'INVENTORY_OUT' THEN l.c_bpartner_id
ELSE null
END) AS **cbpartnerid**
FROM so_transaction i
LEFT JOIN so_orderline j ON j.so_orderline_id = i.so_orderline_id LEFT JOIN so_inventoryline k ON k.so_inventoryline_id = i.so_inventoryline_id
LEFT JOIN so_inventory l ON l.so_inventory_id = k.so_inventory_id
GROUP BY i.created, i.transaction, i.m_product_id, i.productname, i.createdby, **cbpartnerid** ORDER BY i.m_product_id DESC ```
I try to return an empty array [] when i find no entries in my db but i return [{}]. How i can only return [] on empty result set ?
const getUserProfile = (identifier, value) => {
return db.oneOrNone (`
select
p.username,
array_to_json(array_agg(json_strip_nulls(json_build_object('index', pp.index, 'filename', pp.filename)))) as pictures
from person p
left join (select person_id, index, filename from person_picture order by index) pp on p.person_id = pp.person_id
where upper(cast(p.$1~ as text)) = upper(cast($2 as text))
group by p.person_id`, [ identifier, value ])
}
I try this:
coalesce(array_to_json(array_agg(json_strip_nulls(json_build_object('index', pp.index, 'filename', pp.filename)))), '[]') as pictures
but it does not work too.
Just is a CASE expression to check the LEFT JOIN'ed data for emptiness (MAX(pp.index) IS NULL does that in this case with minimal overhead:
SELECT
p.username,
CASE
WHEN max(pp.index) IS NOT NULL THEN
array_to_json(array_agg(json_strip_nulls(json_build_object('index', pp.index, 'filename', pp.filename))))
ELSE
'[]'::json
END as pictures
FROM t_person p
LEFT JOIN (SELECT person_id, index, filename FROM t_person_picture ORDER BY index) pp ON p.person_id = pp.person_id
GROUP BY p.username;

I am working on migrating data from one database to another for a hospital. In the old database, the doctor's specialty IDs are all in one column (swvar_specialties), each separated by commas. In the new database, each specialty ID will have it's own column (example: Specialty1_PrimaryID, Specialty2_PrimaryID, Specialty3_PrimaryID, etc). I am trying to export the data out of the old database and separate these into these separate columns. I know I can use indexof and substring to do this - I just need help with the syntax.
So this query:
Select swvar_specialties as Specialty1_PrimaryID
From PhysDirectory
might return results similar to 39,52,16. I need this query to display Specialty1_PrimaryID = 39, Specialty2_PrimaryID = 52, and Specialty3_PrimaryID = 16 in the results. Below is my query so far. I will eventually have a join to pull the specialty names from the specialties table. I just need to get this worked out first.
Select pd.ref as PrimaryID, pd.swvar_name_first as FirstName, pd.swvar_name_middle as MiddleName,
pd.swvar_name_last as LastName, pd.swvar_name_suffix + ' ' + pd.swvar_name_degree as NameSuffix,
pd.swvar_birthdate as DateOfBirth,pd.swvar_notes as AdditionalInformation, 'images/' + '' + pd.swvar_photo as ImageURL,
pd.swvar_philosophy as PhilosophyOfCare, pd.swvar_gender as Gender, pd.swvar_specialties as Specialty1_PrimaryID, pd.swvar_languages as Language1_Name
From PhysDirectory as pd
The article Split function equivalent in T-SQL? provides some details on how to use a split function to split a comma-delimited string.
By modifying the table-valued function in presented in this article to provide an identity column we can target a specific row such as Specialty1_PrimaryID:
/*
Splits string into parts delimitered with specified character.
*/
CREATE FUNCTION [dbo].[SDF_SplitString]
(
#sString nvarchar(2048),
#cDelimiter nchar(1)
)
RETURNS #tParts TABLE (id bigint IDENTITY, part nvarchar(2048) )
AS
BEGIN
if #sString is null return
declare #iStart int,
#iPos int
if substring( #sString, 1, 1 ) = #cDelimiter
begin
set #iStart = 2
insert into #tParts
values( null )
end
else
set #iStart = 1
while 1=1
begin
set #iPos = charindex( #cDelimiter, #sString, #iStart )
if #iPos = 0
set #iPos = len( #sString )+1
if #iPos - #iStart > 0
insert into #tParts
values ( substring( #sString, #iStart, #iPos-#iStart ))
else
insert into #tParts
values( null )
set #iStart = #iPos+1
if #iStart > len( #sString )
break
end
RETURN
END
Your query can the utilise this split function as follows:
Select
pd.ref as PrimaryID,
pd.swvar_name_first as FirstName,
pd.swvar_name_middle as MiddleName,
pd.swvar_name_last as LastName,
pd.swvar_name_suffix + ' ' + pd.swvar_name_degree as LastName,
pd.swvar_birthdate as DateOfBirth,pd.swvar_notes as AdditionalInformation,
'images/' + '' + pd.swvar_photo as ImageURL,
pd.swvar_philosophy as PhilosophyOfCare, pd.swvar_gender as Gender,
(Select part from SDF_SplitString(pd.swvar_specialties, ',') where id=1) as Specialty1_PrimaryID,
(Select part from SDF_SplitString(pd.swvar_specialties, ',') where id=2) as Specialty2_PrimaryID,
pd.swvar_languages as Language1_Name
From PhysDirectory as pd

The parameters are (:FR_DT,:TO_DT, : p_COMP_CODE, :FR_CAT, :TO_CAT, : p_SUP_CODE) which need to be replaced with '?' while writing the query in dataset. But i don't know how to replace same parameter which is occurring at multiple places with the query parameters. and How to handle DECODE and between parametes.
One option is to use a WITH clause to assign your parameters to a dummy table.
WITH tmp_parms AS (
SELECT ? as fr_dt, ? as to_dt, ? as p_comp_code,
? as fr_cat, ? as to_cat, ? as p_sub_code
FROM dual
)
SELECT C.COMP_CODE,C.MATCODE, ... etc
FROM tmp_parms tp,
(
SELECT A.COMP_CODE,A.MATCODE, ... etc
Or if you'd prefer yet another inline view:
SELECT C.COMP_CODE,C.MATCODE, ... etc
FROM (
SELECT ? as fr_dt, ? as to_dt, ? as p_comp_code,
? as fr_cat, ? as to_cat, ? as p_sub_code
FROM dual
) tp,
(
SELECT A.COMP_CODE,A.MATCODE, ... etc
And then replace all the existing bind variables with references to the equivalent column from the temporary parms table, i.e. change this:
b.grn_date<=:TO_DT)
to this:
b.grn_date<=tp.to_dt)
