Im trying to convert a time that i have in secconds that is stored on a JSON value, and it gives me error of No matching signature for function TIMESTAMP_SECONDS, or in the query results:
Invalid timestamp: '1646985600'
This is the query:
SELECT DATE(TIMESTAMP_SECONDS(JSON_EXTRACT_SCALAR(JSON_EXTRACT(data , '$.fechaCierre'), '$._seconds'))) AS fechaCierre
FROM db Limit 10
When Im querying without the DATE(TIMESTAMP_SECONDS()), like this:
SELECT JSON_EXTRACT_SCALAR(JSON_EXTRACT(data , '$.fechaCierre'), '$._seconds') AS fechaCierre
FROM db Limit 10
Im getting correct the seconds like this: 1646985600
Use below instead
SELECT DATE(TIMESTAMP_SECONDS(CAST(JSON_EXTRACT_SCALAR(JSON_EXTRACT(data , '$.fechaCierre'), '$._seconds') AS INT64))) AS fechaCierre
FROM db Limit 10
The problem was that the result of the previous query was a string, and the TIMESTAMP_SECONDS only receive Int64.
So I change to query like this and it worked:
SELECT date(timestamp_seconds(CAST(JSON_EXTRACT_SCALAR(JSON_EXTRACT(data , '$.fechaCierre'), '$._seconds') AS int64))) AS fechaCierre
FROM db Limit 10

I am trying to extract the id's starting with srsa from the table structure below
id reason_text_field
34394 {"initial_customer":"sda_WWyfr4AXY1fIAS", customer_result":"srsa_CAkAaAvNKL2OSD"}
in order to get the following output:
id srsa_id
34394 srsa_CAkAaAvNKL2OSD
but when I use the following SparkSQL function
REGEXP_EXTRACT(reason_text_field, 'srsa[^"]*') as srsa_id
I get this error:
java.lang.IndexOutOfBoundsException: No group
You need to specify the group to capture. Try this:
SELECT id,
REGEXP_EXTRACT(reason_text_field, '\"(srsa[^"]*)\"', 1) as srsa_id
-- or REGEXP_EXTRACT(reason_text_field, 'srsa[^"]*', 0) as srsa_id
FROM tb
Note however that you can also convert the text column reason_text_field into a map or struct using from_json then extract the field customer_result:
SELECT id,
from_json(reason_text_field, 'map<string,string>')['customer_result'] as srsa_id
FROM tb
I am using an sql script to parse a json into a snowflake table using dbt.
One of the cols contain this datetime value: '2022-02-09T20:28:59+0000'.
What's the correct way to define ISO datetime's data type in Snowflake?
I tried date, timestamp and TIMESTAMP_NTZ like this in my dbt sql script:
JSON_DATA:",my_date"::TIMESTAMP_NTZ AS MY_DATE
but clearly, these aren't the correct one because later on when I test it in snowflake with select * , I get this error:
SQL Error [100040] [22007]: Date '2022-02-09T20:28:59+0000' is not recognized
or
SQL Error [100035] [22007]: Timestamp '2022-02-13T03:32:55+0100' is not recognized
so I need to know which Snowflake time/date data type suits the best for this one
EDIT:
This is what I am trying now.
SELECT
JSON_DATA:"date_transmission" AS DATE_TRANSMISSION
, TO_TIMESTAMP(DATE_TRANSMISSION:text, 'YYYY-MM-DDTHH24:MI:SS.FFTZH:TZM') AS DATE_TRANSMISSION_TS_UTC
, JSON_DATA:"authorizerClientId"::text AS AUTHORIZER_CLIENT_ID
, JSON_DATA:"apiPath"::text API_PATH
, MASTERCLIENT_ID
, META_FILENAME
, META_LOAD_TS_UTC
, META_FILE_TS_UTC
FROM {{ source('INGEST_DATA', 'TABLENAME') }}
I get this error:
000939 (22023): SQL compilation error: error line 6 at position 4
10:21:46 too many arguments for function [TO_TIMESTAMP(GET(DATE_TRANSMISSION, 'text'), 'YYYY-MM-DDTHH24:MI:SS.FFTZH:TZM')] expected 1, g
However, if I comment out the the first 2 lines(related to timpstamp types), the other two work perfectly fine. What's the correct syntax of parsing json with TO_TIMESTAMP?
Not that JSON_DATA:"apiPath"::text API_PATH gives the correct value for it in my snowflake tables.
Did some testing and it seems you have 2 options.
You can either get rid of the +0000 at the end: left(column_date, len(column_date)-5)
or try_to_timestamp with format
try_to_timestamp('2022-02-09T20:28:59+0000','YYYY-MM-DD"T"HH24:MI:SS+TZHTZM')
TZH and TZM are TimeZone Offset Hours and Minutes
So there are 2 main points here.
when getting data from JSON to pass to any of the timestamp functions that want a ::TEXT object, but the values to get from JSON are still ::VARIANT so they need to be cast. This is the cause of the error you quote
(22023): SQL compilation error: error line 6 at position 4
10:21:46 too many arguments for function [TO_TIMESTAMP(GET(DATE_TRANSMISSION, 'text'), 'YYYY-MM-DDTHH24:MI:SS.FFTZH:TZM')] expected 1, g
also your SQL is wrong there it should have been
TO_TIMESTAMP(DATE_TRANSMISSION::text,
How you handle the timezone format.As other have noted you (as I did in your last question) do you want to ignore the timezone values or read them. I forgot about the TZHTZM formatting. Given you have timezone data, you should use the TO_TIMESTAMP_TZ`TRY_TO_TIMESTAMP_TZto make sure the time zone data is keep, given you second example shows+0100`
putting those together (assuming you didn't want an extra date_transmission as a variant in you data) :
SELECT
TO_TIMESTAMP_TZ(JSON_DATA:"date_transmission"::text, 'YYYY-MM-DDTHH24:MI:SS+TZHTZM') AS DATE_TRANSMISSION_TS_UTC
, JSON_DATA:"authorizerClientId"::text AS AUTHORIZER_CLIENT_ID
, JSON_DATA:"apiPath"::text AS API_PATH
, MASTERCLIENT_ID
, META_FILENAME
, META_LOAD_TS_UTC
, META_FILE_TS_UTC
FROM {{ source('INGEST_DATA', 'TABLENAME') }}
You should use timestamp (not date which does not store the time information), but probably the format you are using is not autodetected. You can specify the input format as YYYY-MM-DD"T"HH24:MI:SSTZHTZM as shown here. The autodetected one has a : between the TZHTZM.
I'm fetching data from the JSON column by using the following query.
SELECT id FROM ( SELECT id,JSON_ARRAY_ELEMENTS(shipment_lot::json) AS js2 FROM file_table WHERE ('shipment_lot') = ('shipment_lot') ) q WHERE js2->> 'invoice_number' LIKE ('%" abc1123"%')
My Postgresql version is 9.3
Saved data in JSON column:
[{ "id"=>2981, "lot_number"=>1, "activate"=>true, "invoice_number"=>"abc1123", "price"=>378.0}]
However, I'm getting this error:
ActiveRecord::StatementInvalid (PG::InvalidParameterValue: ERROR: cannot extract element from a scalar:
SELECT id FROM
( SELECT id,JSON_ARRAY_ELEMENTS(shipment_lot::json)
AS js2 FROM file_heaps
WHERE ('shipment_lot') = ('shipment_lot') ) q
WHERE js2->> 'invoice_number' LIKE ('%abc1123%'))
How I can solve this issue.
Your issue is that you have improper JSON stored
If you try running your example data on postgres it will not run
SELECT ('[{ "id"=>2981, "lot_number"=>1, "activate"=>true, "invoice_number"=>"abc1123", "price"=>378.0}]')::json
This is the JSON formatted correctly:
SELECT ('[{ "id":2981, "lot_number":1, "activate":true, "invoice_number":"abc1123", "price":378.0}]')::json
I have the following table schema prepared by AWS glue
When I query the table using SELECT * FROM "vietnam-property-develop"."sell" limit 10;, it throws an error:
HIVE_BAD_DATA: Error parsing field value '{"area":"85
m²","date":"14/01/2020","datetime":"2020-01-18
00:42:28.488576+00:00","address":"Quan Hoa - Cầu Giấy","price":"20

org.openx.data.jsonserde.json.JSONObject cannot be cast to
java.lang.Double
Then I tired to just query the title column by using SELECT title FROM "vietnam-property-develop"."sell" limit 10;
It returns result which I didn't expect. It seems that the query return the whole json files instead of just the title column. And the number of rows is 4 but not 10 no matter how I modify the query.
I want a query like:
select tp.package_rate, sum(sell) as sold_quantity , select(tp.package_rate * sold_quantity ) as sell_amount from tbl_ticket_package tp where tp.event_id=1001
here the system firing error while doing the multiplication as
sold_quantity is invalid column
another problem is that in multiplication I want to use package_rate which got by select query from tp.package_rate but it multiplying with all package_rate of the table but I want only specific package_rate which was output of select query
What would you suggest? I want to bind this query in gridview . is there any way to do it using ASP.net gridview?
Your problem is that you are referring to sold_quantity here :
select(tp.package_rate * sold_quantity )
The alias is not recognized at this point.You will have to replace it with sum(sales). You will also have to group by tp.package_rate.
Your query should ideally be like :
select tp.package_rate, sum(sell) as sold_quantity ,
(tp.package_rate * sum(sell) ) as sell_amount from tbl_ticket_package tp
where tp.event_id=1001 group by tp.package_rate;
I am guessing that tp.package_rate is unique for a given event_id, from latter part of your question. If that's not the case, the sql you have written makes no sense.
