I'm trying to execute the following query:
SELECT
(SELECT ep.value FROM ep
WHERE ep.key = 'key_name') AS key_name
FROM analytics_tables.events_20210824 e CROSS JOIN
UNNEST(event_params) AS ep
WHERE e.event_name = 'item_clicked' AND
ep.key = 'my_key_type' and ep.value.int_value=7;
But I'm getting this error message:
Table name "ep" missing dataset while no default dataset is set in the request
How should I reference "ep" in order for it to work?
Try below
SELECT
(SELECT value FROM e.event_params
WHERE key = 'key_name') AS key_name
FROM analytics_tables.events_20210824 e CROSS JOIN
UNNEST(event_params) AS ep
WHERE e.event_name = 'item_clicked' AND
ep.key = 'my_key_type' and ep.value.int_value=7;
You should set your database first before handling the table, otherwise it won't know to which database extract the data from.
USE database;
This solution has been extracted from the following quickstart.

I have in where event_params.key = 'page_referrer'
but, i want to see in select values event_params.key = 'traffic_type'
I need both fields
I wanted to use JOIN tables with itself, but didn't work out
Would you try below ?
SELECT (SELECT value.string_value FROM t.event_params WHERE key = 'traffic_type') traffic_type
FROM `coolclever-1148.analytic_xxxxxx.events_20230130` t
WHERE event_name = 'view_item' AND 'page_referrer' IN UNNEST(event_params.key);
Example Query
To show you working example with public dataset:
SELECT (SELECT value.string_value FROM t.event_params WHERE key = 'page_location') page_location
FROM `bigquery-public-data.ga4_obfuscated_sample_ecommerce.events_*` t
WHERE event_name = 'page_view' AND 'page_title' IN UNNEST(event_params.key);
Query results
I have two tables which are totally independent from each other, and I need to extract information from both of them and generate a CSV.
I'm doing this query:
SELECT NOM_FLUX, TYPE_CONTENU, DATE_DEPOT_GED
FROM FLUX_GED
WHERE TYPE_CONTENU = 'TEMPO_COURRIER_FSS'
AND NOM_FLUX NOT LIKE 'PCC%'
With this result:
Then I'm doing a query from this result with the ID
Like This (on the first result)
SELECT ID, URL_RELATIVE, TYPE_CONTENU, NOM_ELEMENT
FROM ELEMENT_GED
WHERE ID IN (
SELECT ID_ELEMENT
FROM SUIVI_GED
WHERE ID_FLUX IN (18682403)
)
With this result:
And here is the information from the SUIVI_GED table:
First I would like to do like a PowerShell foreach loop on every ID of my first query and then export the result of both query in a common csv.
I would like a result like that for my csv:
NOM_FLUX;URL_RELATIVE;TYPE_CONTENU;NOM_ELEMENT
infoNomFlux;infoURL;infoType;infoNOM
You seem to want join. A rather literal translation of your queries would be:
select
f.nom_flux,
f.type_contenu as type_contenu_flux,
f.date_depot_ged ,
e.id,
e.url_relative,
e.type_contenu as type_contenu_element,
e.nom_element
from flux_ged f
inner join element_ged e
on exists (select 1 from suivi_ged s where s.id_flux = f.id and e.id = s.id)
where
f.type_contenu = 'TEMPO_COURRIER_FSS'
and f.nom_flux not like 'PCC%'
Depending on your actual design, you might be able to flatten the exists condition as another join:
select
f.nom_flux,
f.type_contenu as type_contenu_flux,
f.date_depot_ged ,
e.id,
e.url_relative,
e.type_contenu as type_contenu_element,
e.nom_element
from flux_ged f
inner join suivi_ged s on s.id_flux = f.id
inner join element_ged e on e.id = s.id
where
f.type_contenu = 'TEMPO_COURRIER_FSS'
and f.nom_flux not like 'PCC%'
SELECT A.GRPNO, A.EMPNO, A.DEPNO, A.PENDCD FROM EMPDEP A, EEDPELIG B
WHERE A.GRPNO=B.GRPNO
AND A.EMPNO=B.EMPNO
AND A.DEPNO=B.DEPNO
AND A.GRPNO = 6606 AND A.SPOUSE = 'T'
AND B.ELIGFLAG01 = 'T' AND SNAPTHRUDT ='DEC312999'
Our selection statement has been successful at pulling the information we need however we're new with SQL and are struggling to create an update statement that is replacing the "a.pendcd=0" to "a.pendcd=20" from the information in the select statement. Any help is appreciated, thank you.
update a
a.pendcd=20
FROM EMPDEP A inner join EEDPELIG B
on A.GRPNO=B.GRPNO
AND A.EMPNO=B.EMPNO
AND A.DEPNO=B.DEPNO
AND A.GRPNO = 6606 AND A.SPOUSE = 'T'
AND B.ELIGFLAG01 = 'T' AND SNAPTHRUDT ='DEC312999'
where a.pendcd=0
Oracle does not support FROM or JOIN in UPDATE (under most circumstances).
Just use EXISTS:
UPDATE EMPDEP ed
SET . . .
WHERE EXISTS (SELECT 1
FROM EEDPELIG p
WHERE ed.GRPNO = p.GRPNO AND
ed.EMPNO= p.EMPNO AND
ed.DEPNO= p.DEPNO AND
p.ELIGFLAG01 = 'T'
)
ed.GRPNO = 6606 AND
ed.SPOUSE = 'T' AND
ed.SNAPTHRUDT ='DEC312999';
It is unclear if the condition on SNAPTHRUDT is on the outer table or inner table. If it is on p, then move it to the subquery.
You can use MERGE statement as following:
Lets assume EMPDEP table has primary key which is EMPDEP_UID.
MERGE INTO EMPDEP TRG
USING
(SELECT A.EMPDEP_UID, A.PENDCD
FROM EMPDEP A, EEDPELIG B
WHERE A.GRPNO=B.GRPNO
AND A.EMPNO=B.EMPNO
AND A.DEPNO=B.DEPNO
AND A.GRPNO = 6606
AND A.SPOUSE = 'T'
AND B.ELIGFLAG01 = 'T'
AND SNAPTHRUDT ='DEC312999') SRC
ON (TRG.EMPDEP_UID = SRC.EMPDEP_UID)
WHEN MATCHED THEN
UPDATE SET TRG.PENDCD = 0
WHERE TRG.PENCD = 20;
You can use unique keys instead of primary key to identify the records to be updated. But it is safe to use primary key as unique key can contain nulls which can change the behaviour of our query.

I am trying to assign key to each distinct value in bigquery with row_number. But it is giving resource exceeding error. So can I achieved same thing with array_aggegate function?
code :
select a.values
, a.type
, max_key + row_number() over(order BY a.values) key
, a.event_date
from gaid_raw a
LEFT JOIN existing_key_table e
on e.type = a.type
and e.values = a.values
left join (
select type, coalesce(max(key),0) max_key from existing_key_table group by 1
) e1
on e1.type = a.type
where e.key is null
I'm not sure if this will fix your problem, but I think this is the logic you want:
select gr.values, gr.type
coalesce(max_key, 0) + row_number() over (partition by gr.type order by gr.values) as key,
gr.event_date
from gaid_raw gr left join
(select type, max(key) as max_key
from existing_key_table
group by 1
) e
on e.type = gr.type
where not exists (select 1
from existing_key_table e
where e.type = gr.type and e.values = gr.values
);
For unrecognized types, you need the coalesce() in the outer select, not the subquery.
You also seem to want to assign sequential numbers based on the type.
If you still get resource errors, there is a way to fix this, but a bit more information is needed about the data. However, I have in the past used random values for such keys -- assuming the ordering is not needed. There is such a small chance of collision that it has worked on fairly large data.
Now, I would use GENERATE_UUID() for a unique id.
I have a table where I wish to update some of the rows. All the fields are not null. I'm doing a sub-query, and I wish to update the table with the non-Null results.
See Below for my final answer:
In MySQL, I solve this problem by doing an UPDATE IGNORE. How do I make this work in SQL Server 2005? The sub-query uses a four-table Join to find the data to insert if it exists. The Update is being run against a table that could have 90,000+ records, so I need a solution that uses SQL, rather than having the Java program that's querying the database retrieve the results and then update those fields where we've got non-Null values.
Update: My query:
UPDATE #SearchResults SET geneSymbol = (
SELECT TOP 1 symbol.name FROM
GeneSymbol AS symbol JOIN GeneConnector AS geneJoin
ON symbol.id = geneJoin.geneSymbolID
JOIN Result AS sSeq ON geneJoin.sSeqID = sSeq.id
JOIN IndelConnector AS joiner ON joiner.sSeqID = sSeq.id
WHERE joiner.indelID = #SearchResults.id ORDER BY symbol.id ASC)
WHERE isSNV = 0
If I add "AND symbol.name IS NOT NULL" to either WHERE I get a SQL error. If I run it as is I get "adding null to a non-null column" errors. :-(
Thank you all, I ended up finding this:
UPDATE #SearchResults SET geneSymbol =
ISNULL ((SELECT TOP 1 symbol.name FROM
GeneSymbol AS symbol JOIN GeneConnector AS geneJoin
ON symbol.id = geneJoin.geneSymbolID
JOIN Result AS sSeq ON geneJoin.sSeqID = sSeq.id
JOIN IndelConnector AS joiner ON joiner.sSeqID = sSeq.id
WHERE joiner.indelID = #SearchResults.id ORDER BY symbol.id ASC), ' ')
WHERE isSNV = 0
While it would be better not to do anything in the null case (so I'm going to try to understand the other answers, and see if they're faster) setting the null cases to a blank answer also works, and that's what this does.
Note: Wrapping the ISNULL (...) with () leads to really obscure (and wrong) errors.
with UpdatedGenesDS (
select joiner.indelID, name, row_number() over (order by symbol.id asc) seq
from
GeneSymbol AS symbol JOIN GeneConnector AS geneJoin
ON symbol.id = geneJoin.geneSymbolID
JOIN Result AS sSeq ON geneJoin.sSeqID = sSeq.id
JOIN IndelConnector AS joiner ON joiner.sSeqID = sSeq.id
WHERE name is not null ORDER BY symbol.id ASC
)
update Genes
set geneSymbol = upd.name
from #SearchResults a
inner join UpdateGenesDs upd on a.id = b.intelID
where upd.seq =1 and isSNV = 0
this handles the null completely as all are filtered out by the where predicate (can also be filtered by join predicate if You wish. Is it what You are looking for?
Here's another option, where only those rows in #SearchResults that are succesfully joined will be udpated. If there are no null values in the underlying data, then the inner joins will pull in no null values, and you won't have to worry about filtering them out.
UPDATE #SearchResults
set geneSymbol = symbol.name
from #SearchResults sr
inner join IndelConnector AS joiner
on joiner.indelID = sr.id
inner join Result AS sSeq
on sSeq.id = joiner.sSeqID
inner join GeneConnector AS geneJoin
on geneJoin.sSeqID = sSeq.id
-- Get "lowest" (i.e. first if listed alphabetically) value of name for each id
inner join (select id, min(name) name
from GeneSymbol
group by id) symbol
on symbol.id = geneJoin.geneSymbolID
where isSNV = 0 -- Which table is this value from?
(There might be some syntax problems, without tables I can't debug it)
