I have two tables in postgresql.
the first (product) has sku json row ([149461190])
the second (item) has an ordinary sku column
How can I join them on sku?
I tried this, but it didn't work.
cannot recognize input near 'jsonb_to_recordset' '(' 'ps' in joinSourcePart
select * from product ps
, jsonb_to_recordset(ps.sku -> 'ps_sku') as (sku text)
join item v using sku
I hope this query help you, You can see data structure and sample data in dbfiddle
select
*
from
product p
cross join jsonb_array_elements_text(p.sku -> 'ps_sku') as j(sku)
inner join item i on i.sku = j.sku :: numeric

Please help me to write correct query for a few tables. I need to replace all id here from another table
api json
I am trying to make query like this
SELECT incident.`number`, `user`.first_name, (SELECT `user`.first_name from ITSM.`user` JOIN incident on `user`.sys_id = incident.id_created_by) as createdby
from ITSM.incident
JOIN ITSM.`user` on incident.id_caller = `user`.sys_id
;*
but it doesn#t work, I got an error: Subquery returns more than 1 row
How can i make a right query?
This one doesn't work also, same error:
SELECT incident.`number`, (SELECT user.first_name from ITSM.`user`, ITSM.incident WHERE user.sys_id = incident.id_created_by) as createdby
from ITSM.incident
JOIN ITSM.`user` on incident.id_caller = user.sys_id*
;
and this is my
DB id for user who created
You don't need a subquery. Just refer to the source table of each column in the select clause, here if you need 2 joins to the same table give these an alias and refer to the columns using that alias.
SELECT incident.`number`
, caller.first_name as caller_name
, creator.first_name AS createdby
FROM ITSM.incident
JOIN ITSM.`user` AS caller ON incident.id_caller = caller.sys_id
JOIN ITSM.`user` AS creator ON incident.id_created_by = creator.sys_id
Nb. I'm assuming your join logic is correct

I understood that product is a table and this table has a field by name sku and by type JSON, and JSON has a key by name ps_sku
If the ps_sku key value is an integer type then:
select * from product pr
inner join item itm on itm.sku = (pr.sku->'ps_sku')::integer
If the ps_sku key value is a text type then:
select * from product pr
inner join item itm on itm.sku = (pr.sku->'ps_sku')::text
pr.sku->'ps_sku' this command extract value of ps_sku key from JSON string (from sku field)
I want to write an MySQL Query where I replace a JSON Array with Data from another Table.
I have got two Tables, "Reserved" and "Seats". Reserved contains one column "Seats", an JSON Array referring to the ID of the Table "Seats". Table Seats also contains a column "Name". I now want to basically replace the IDs in the JSON Data of the Seats column of the Reserved Table, with the name of the corresponding IDs stored in the Seats Table.
Is there a way to do this in an Mysql Query. I do not know how to pack a query result in a JSON Format and return it as a column
I already tried to utilize JSON_EXTRACT somehow : see test below.
SELECT * FROM `seats` WHERE ID = JSON_EXTRACT('["276", "277", "278"]','$.*')
Basically I want a Query like this:
SELECT *,
JSONCreate(SELECT name from `seats` WHERE seats.id IN JSON_EXTRACT(reserved.seats)) as name
FROM `reserved`
WHERE 1
You can use one of the following solutions.
solution using JSON_SEARCH and JSON_ARRAYAGG
SELECT r.seats, JSON_ARRAYAGG(s.name)
FROM reserved r JOIN seats s ON JSON_SEARCH(r.seats, 'one', CONVERT(s.id, CHAR(10))) IS NOT NULL
GROUP BY r.seats
solution using ... MEMBER OF () and JSON_ARRAYAGG
SELECT r.seats, JSON_ARRAYAGG(s.name)
FROM reserved r INNER JOIN seats s ON CONVERT(s.id, CHAR) MEMBER OF(r.seats)
GROUP BY r.seats
solution using JSON_CONTAINS and JSON_ARRAYAGG
SELECT r.seats, JSON_ARRAYAGG(s.name)
FROM reserved r INNER JOIN seats s ON JSON_CONTAINS(r.seats, JSON_QUOTE(CONVERT(s.id, CHAR))) = 1
GROUP BY r.seats
You can also use JSON_TABLE to solve this:
SELECT JSON_ARRAYAGG(IFNULL(s.name, ''))
FROM reserved r, JSON_TABLE(
r.seats,
"$[*]" COLUMNS (
id CHAR(50) PATH "$"
)
) AS rr LEFT JOIN seats s ON rr.id = s.id
GROUP BY r.seats
Note: You can use INNER JOIN to remove the empty values. Instead of GROUP BY r.seats you should use a id column.

SELECT quantity, materialTypeId ,
(SELECT typeName
FROM invTypes
WHERE TypeID IN (SELECT materialTypeId
FROM invTypeMaterials
WHERE typeId= 12743
)
) AS material
FROM invTypeMaterials
WHERE TypeID=12743
so this query gives me nice results except the column material. only shows me the first entry instead of giving the name of each row.
if i run these sql seperate they work and i do see what i want. i just need them combined into 2 columns.
what i want to do is, i query one table for data, one of the column has a value wich i want to convert to a name, and that is in another table and its linked by a unique TypeID
Chilly
May be this will work :
SELECT tm.quantity, tm.materialTypeId , t.typeName
FROM invTypeMaterials tm
INNER JOIN invTypes t ON t.TypeID = tm.materialTypeId
WHERE tm.TypeID=12743
If you want to lookup the materialTypeID's name for the current record, you must not use a separate subquery but use the materialTypeID value from the outer query.
This is called a correlated subquery:
SELECT quantity, materialTypeId,
(SELECT typeName
FROM invTypes
WHERE TypeID = invTypeMaterials.materialTypeId
) AS material
FROM invTypeMaterials
WHERE TypeID=12743
I am running into some trouble with the following circumstances:
I have a query that creates two temp tables, and the following select to join them together--
SELECT * FROM result
INNER JOIN result2 ON result2.packetDetailsId = result.packetDetailsId
I am then trying to create another column from concatenating a few of the resulting fields and then use that to reference/query against another table. Is there a way to accomplish this in one query? Should I get away from the temp tables?
Thank you again in advance.
update: If I try to alias the combination of the two temp tables I get an error message stating [Err] 1060 - Duplicate column name 'packetDetailsId'
select * from (
SELECT * FROM result
INNER JOIN result2 ON result2.packetDetailsId = result.packetDetailsId) as myalias
Another Update: I almost have it working as one query but I get the result "(BLOB)" in the column I concoctenated:
select packet_details.packetDetailsId,products.productId,Credit,AccountNum,OrderStat, CONCAT(products.productId,Credit,'_',OrderStat) as consol from (
select packetDetailsId, GROUP_CONCAT(Credit) AS Credit, GROUP_CONCAT(AccountNum) AS AccountNum, GROUP_CONCAT(OrderStat) AS OrderStat FROM
( SELECT pd_extrafields.packetDetailsId,
CASE WHEN pd_extrafields.ex_title LIKE ('%Credit%')
THEN pd_extrafields.ex_value ELSE NULL END as Credit,
CASE WHEN pd_extrafields.ex_title LIKE ('%Account%')
THEN pd_extrafields.ex_value ELSE NULL END as AccountNum,
CASE WHEN pd_extrafields.ex_title LIKE ('%Existing%')
THEN pd_extrafields.ex_value ELSE NULL END as OrderStat
FROM pd_extrafields )AS TempTab GROUP BY packetDetailsId ) as alias2
INNER JOIN packet_details ON alias2.packetDetailsId = packet_details.packetDetailsId
INNER JOIN sales ON packet_details.packetDetailsId = sales.packetDetailsId
INNER JOIN sold_products ON sales.saleId = sold_products.saleId
INNER JOIN products ON sold_products.productId = products.productId
If I understand correctly, you already have the temporary tables created and you need to "concatenate" the results, using from ... inner join ...
The only possible restriction you may have is that you can only reference your temporary tables once in your from clause; besides that, there are no other restrictions (I frequently use temporary tables as intermediate steps in the creation of my final result).
Tips
Let's say your temp tables are temp_result1 and temp_result2. Both tables have a field packedDetailsId, on which the join will be performed. Remember to create the appropriate indexes on each table; at the very least you need to index packedDetailsId on both tables:
alter table temp_result1
add index PDI(packedDetailsId);
alter table temp_result2
add index PDI(packedDetailsId);
Now, just execute a query with the desired join and concatenation. If concat returns BLOB, then cast the result as char (of course, I'm assuming you need a text string):
select r1.*, r2.*, cast(concat(r1.field1, ',', r2.field2) as char) as data_concat
from temp_result1 as r1
inner join temp_result2 as r2 on r1.packedDetailsId = r2.packedDetailsId;
I see your problem is that GROUP_CONCAT is returning BLOB values... It's normal (MySQL doesn't know a priori how to return the values, so it returns binary data); just use the cast function.
Hope this helps you
so, if the result2 and result are both temp tables, you will have to include the # if local temp table and ## if global temp table
so your statements should be :
SELECT * FROM #result
INNER JOIN #result2 ON #result2.packetDetailsId = #result.packetDetailsId
