I'm following https://datatables.net/reference/option/columns.data ("data": { "_": "phone", "filter": "phone_filter", "display": "phone_display"}) to supply structured values for certain columns of the dataTables table, other columns are just simple:
{"filter": "1964486", "display": "Elite 2022 Tryout ('17-'18)", "_": 1964486}
It works fine, displays the display value, searches by the filter value. But in certain places I need to programatically obtain the full data structure (see above) from the cell. However when I try to access it through the API (let's say we are talking about the first row's 6th column's cell data):
myTable.cell(0, 5).data()
This returns only 1964486 instead of the full structure. How can I access the display value?
render() can do that:
myTable.cell(0, 5).render('display')
https://datatables.net/reference/api/cell().render()
It can also return filter and sort values.

I have a table. There are many columns and rows. One column that I am trying to query in Snowflake has semi structured data. For example, when I query
select response
from table
limit 5
This is what is returned
[body={\n "id": "xxxxx",\n "object": "charge",\n "amount": 500,\n "amount_refunded": 0,\n "application": null,\n "application_fee": null,\n "application_fee_amount": null,\n "balance_transaction": null,\n "billing_details": {\n "address": {\n "city": null,\n "zip": "xxxxx",]
I want to select only the zip in this data. When I run code:
select response:zip
from table
limit 5
I get an error.
SQL compilation error: error line 1 at position 21 Invalid argument types for function 'GET': (VARCHAR(16777216), VARCHAR(11))
Is there a reason why this is happening? I am new to snowflake so trying to parse out this data but stuck. Thanks!
Snowflake has very good documentation on the subject
For your specific case, have you attempted to use dot notation? It's the appropiate method for accessing JSON. So
Select result:body.zip
from table
Remember that you have your 'body' element. You need to access that one first with semicolon because it's a level 1 element. Zip is located within body so it's a level 2. Level 1 elements are accessed with semicolon, level 2 elements are accessed with dot notation.
I think you have multiple issues with this.
First I think your response column is not a variant column. Please run the below query and confirm
SHOW COLUMNS ON table;
Even if the column is variant, the way the data is stored is not in a valid JSON format. You will need to strip the JSON part and then store that in the variant column.
Please do the first part and share the information, I will then suggest next steps. I wanted to put that in the comment but comment does not allow to write so many sentences.
I have JSON data in my collection similar to following example. There is a icCount property with numeric value. Now when I issue a query with order specified by icCount, its sorted as text and not numeric value (see screenshot below). Index is automatic here. Any idea what is wrong here? (running RavenDB 4.1.1)
{
"enabled": true,
"description": "",
"icCount": 3865,
"companyname": "ABC Data"
}
Ok, so I just found it myself. Help here https://ravendb.net/docs/article-page/4.1/csharp/indexes/querying/sorting states that I should specify ordering mode(type). For my case I can simply rewrite it to: order by icCount as long desc ... see the long in clause. This way my data list is ordered correctly.
I've a sql column filled with json document, one for row:
[{
"ID":"TOT",
"type":"ABS",
"value":"32.0"
},
{
"ID":"T1",
"type":"ABS",
"value":"9.0"
},
{
"ID":"T2",
"type":"ABS",
"value":"8.0"
},
{
"ID":"T3",
"type":"ABS",
"value":"15.0"
}]
How is it possible to trasform it into tabular form? I tried with redshift json_extract_path_text and JSON_EXTRACT_ARRAY_ELEMENT_TEXT function, also I tried with json_each and json_each_text (on postgres) but didn't get what expected... any suggestions?
desired results should appear like this:
T1 T2 T3 TOT
9.0 8.0 15.0 32.0
I assume you printed 4 rows. In postgresql
SELECT this_column->'ID'
FROM that_table;
will return column with JSON strings. Use ->> if you want text column. More info here: https://www.postgresql.org/docs/current/static/functions-json.html
In case you were using some old Postgresql (before 9.3), this gets harder : )
Your best option is to use COPY from JSON Format. This will load the JSON directly into a normal table format. You then query it as normal data.
However, I suspect that you will need to slightly modify the format of the file by removing the outer [...] square brackets and also the commas between records, eg:
{
"ID": "TOT",
"type": "ABS",
"value": "32.0"
}
{
"ID": "T1",
"type": "ABS",
"value": "9.0"
}
If, however, your data is already loaded and you cannot re-load the data, you could either extract the data into a new table, or add additional columns to the existing table and use an UPDATE command to extract each field into a new column.
Or, very worst case, you can use one of the JSON Functions to access the information in a JSON field, but this is very inefficient for large requests (eg in a WHERE clause).
I am trying to get the ID under "General" from a feature item in rally. This is my query:
body = { "find" => {"_ProjectHierarchy" => projectID, "_TypeHierarchy" => "PortfolioItem/Feature"
},
"fields" => ["FormattedID","Name","State","Release","_ItemHierarchy","_TypeHierarchy","Tags"],
"hydrate" => ["_ItemHierarchy","_TypeHierarchy","Tags"],
"fetch"=>true
}
I am not able to get any value for FormattedID, I tried using "_UnformattedID" but it pulls up an entirely different value than the FormattedID. Any help would be appreciated.
LBAPI does not have FormattedID field. You are correct using _UnformattedID. It is the FormattedID without the prefix. For example, this query:
https://rally1.rallydev.com/analytics/v2.0/service/rally/workspace/1111/artifact/snapshot/query.js?find={"_ProjectHierarchy":2222,"_TypeHierarchy":"PortfolioItem/Feature","State":"Developing",_ValidFrom: {$gte: "2013-06-01TZ",$lt: "2013-09-01TZ"}},sort:{_ValidFrom:-1}}&fields=["_UnformattedID","Name","State"]&hydrate=["State"]&compress=true&pagesize:200
shows _UnformattedID that correspond to FormattedID as this screenshot shows:
I noticed your are using fields and fetch . Per LBAPI's documentation, it uses fields rather than fetch. If you want to get all fields, use fields=true
As far as the missing custom fields, make sure that the custom field value was set within the dates of the query.
Compare these almost identical queries: the first query does not return a custom field, the second query does.
Query #1:
https://rally1.rallydev.com/analytics/v2.0/service/rally/workspace/1111/artifact/snapshot/query.js?find={"_ProjectHierarchy":2222,"_TypeHierarchy":"PortfolioItem/Feature","State":"Developing",_ValidFrom: {$gte: "2013-06-01TZ",$lt: "2013-09-01TZ"}}}&fields=["_UnformattedID","Name","State","c_PiCustomField"]&hydrate=["State","c_PiCustomField"]
Query #2:
https://rally1.rallydev.com/analytics/v2.0/service/rally/workspace/11111/artifact/snapshot/query.js?find={"_ProjectHierarchy":2222,"_TypeHierarchy":"PortfolioItem/Feature","State":"Developing",__At: "current"}&fields=["_UnformattedID","Name","State","c_PiCustomField"]&hydrate=["State","c_PiCustomField"]
The first query uses time period: _ValidFrom: {$gte: "2013-06-01TZ",$lt: "2013-09-01TZ"}
The second query uses __At: "current"
Let's say I just create a new custom field on PortfolioItem. It is not possible to create a custom field on PorfolioItem/Feature, so the field is created on PI, but both queries still use "_TypeHierarchy":"PortfolioItem/Feature".
After I created this custom field, called PiCustomField, I set a value of that field for a specific Feature, F4.
The first query does not have a single snapshot that includes that field because that field did not exist in the time period we lookback. We can't change the past.
The second query returns this field for F4. It does not return it for other Features because all other Features do not have this field set.
Here is the screenshot:
I want to add a table to my database that holds group filters so crystal reports can retrieve its filter criteria from which ever row it is currently on. I want to do this so I can have some form of filter template.
I have been successful with this if only ONE filter such as:
{Devices.Test} like "1";
But if I have multiple:
{Devices.Test} like ["1", "1.1", "1.2", "1.3", "1.4", "1.5", "5", "6"];
It ignores the filter, I guess because the filter is being passed to Crystal Reports as a string instead of Crystal Reports recognizing that its an array.
Has anyone ever done something like this before?
Use:
MakeArray(Split({databaseColumn}, DelimeterType))
And pass that off to your filter criteria. That will split your string up into an array that crystal reports can recognize.
