I am trying to create a dashboard that consist from two components: CCC Bar chart and Multiple select component.
I use the multiply select component for assignment param value, which is using in the datasource. (MDX query):
SELECT
NON EMPTY {[Measures].[doc_count]} ON COLUMNS,
NON EMPTY {[Dimension Usage date_publish.Hierarchy date_publish].[date_publish].Members} ON ROWS
FROM [Docs]
WHERE CrossJoin({${param_hosts}}, {[event].[active]})
So if I set (multiply select component) property value array with pairs:
( {arg:[host].[news.com] value:news.com}, {{arg:[host].[somesite.com] value:somesite.com}} ), everything work perfect.
The parameter is bound to the component receives the correct value, for example: [host]. [News.com], [host]. [Somesite.com].
But if I try to fill the multiply select component from the datasource it become unworkable.
As DataSource, I use the sql over sqlJndi with query: SELECT distinct (host) as Id, concat ('[host]. [', Host, ']') as Value FROM docs_fact where dim_event_id = 1;
The result this query is a table:
id value
news.com | [host].[news.com]
somesite.com | [host].[somesite.com]
Parameter is assigned a value: news.com, somesite.com
Changing the properties of the Value as id only affects which of the fields (id or value) will be shown to the user, and the parameter's value is not affected.
Tell me please, is it possible to specify which of the columns to be used for display to the user and which of the columns to be used to generate results?
No, but you can change the dataset on the clientside using the postFetch function on the multi-select component.
function (dataset) {
for (var i=0; i < dataset.resultset.length; i++) {
var temp = dataset.resultset[i][0];
dataset.resultset[i][0] = dataset.resultset[i][1];
dataset.resultset[i][1] = temp;
}
return dataset;
}
Or similar

My ELT tools imports my data in bigquery and generates/extends automatically the schema for dynamic nested keys (in the schema below, under properties)
It looks like this
How can I get the list of nested keys of a repeated record ? so for example I can group by properties when those items have said property non-null ?
I have tried
select column_name
from my_schema.INFORMATION_SCHEMA.COLUMNS
where
table_name = 'my_table
But it will only list first level keys
From the picture above, I want, as a first step, a SQL query that returns
message
user_id
seeker
liker_id
rateable_id
rateable_type
from_organization
likeable_type
company
existing_attempt
...
My real goal through, is to group/count my data based on a non-null value of a 2nd level nested properties properties.filters.[filter_type]
The schema may evolve when our application adds more filters, so this need to be dynamically generated, I can't just hard-code the list of nested keys.
Note: this is very similar to this question How to extract all the keys in a JSON object with BigQuery but in my case my data is already in a shcema and it's not a JSON object
EDIT:
Suppose I have a list of such records with nested properties, how do I write a SQL query that adds a field "enabled_filters" which aggregates, for each item, the list of properties for wihch said property is not null ?
Example input (properties.x are dynamic and not known by the programmer)
search_id
properties.filters.school
properties.filters.type
1
MIT
master
2
Princetown
null
3
null
master
Example output
search_id
enabled_filters
1
["school", "type"]
2
["school"]
3
["type"]
Have you looked at COLUMN_FIELD_PATHS? It should give you the paths for all columns.
select field_path from my_schema.INFORMATION_SCHEMA.COLUMN_FIELD_PATHS where table_name = '<table>'
[https://cloud.google.com/bigquery/docs/information-schema-column-field-paths]
The field properties is not nested by array only by structures. Then a UDF in JavaScript to parse thise field should work fast enough.
CREATE TEMP FUNCTION jsonObjectKeys(input STRING, shownull BOOL,fullname Bool)
RETURNS Array<String>
LANGUAGE js AS """
function test(input,old){
var out=[]
for(let x in input){
let te=input[x];
out=out.concat(te==null ? (shownull?[x+'==null']:[]) : typeof te=='object' ? test(te,old+x+'.') : [fullname ? old+x : x] );
}
return out;
Object.keys(JSON.parse(input));
}
return test(JSON.parse(input),"");
""";
with tbl as (select struct(1 as alpha,struct(2 as x, 3 as y,[1,2,3] as z ) as B) A from unnest(generate_array(1,10*1))

select *,

I have a procedure with the parameter IT_ATINN:
IMPORTING
REFERENCE(IT_ATINN) TYPE STRING_TABLE
IT_ATINN contains a list of characteristics.
I have the following code:
LOOP AT values_tab INTO DATA(value).
SELECT ( #value-INSTANCE ) AS CUOBJ
FROM IBSYMBOL
WHERE SYMBOL_ID = #value-SYMBOL_ID
AND ATINN ??? "<======== HERE ???
APPENDING TABLE #DATA(ibsymbol_tab).
ENDLOOP.
How can I check if ATINN (in the WHERE clause) is equal to any entry in IT_ATINN?
To achieve what you want (and I assume you want dynamic SELECT fields) you cannot use inline declarations here, both in LOOP and in SELECT:
The structure of the results set must be statically identifiable. The SELECT list and the FROM clause must be specified statically and host variables in the SELECT list must not be generic.
So either you use inline or use dynamics, not both.
Here is the snippet that illustrates Sandra good suggestion:
TYPES: BEGIN OF ty_value_tab,
instance TYPE char18,
symbol_id TYPE id,
END OF ty_value_tab.
DATA: it_atinn TYPE string_table.
DATA: rt_atinn TYPE RANGE OF atinn,
value TYPE ty_value_tab,
values_tab TYPE RANGE OF ty_value_tab,
ibsymbol_tab TYPE TABLE OF ibsymbol.
rt_atinn = VALUE #( FOR value_atinn IN it_atinn ( sign = 'I' option = 'EQ' low = value_atinn ) ).
APPEND VALUE ty_value_tab( instance = 'ATWRT' ) TO values_tab.
LOOP AT values_tab INTO value.
SELECT (value-instance)
FROM ibsymbol
WHERE symbol_id = #value-symbol_id
AND atinn IN #rt_atinn
APPENDING CORRESPONDING FIELDS OF TABLE #ibsymbol_tab.
ENDLOOP.
Overall, it makes no sense select ibsymbol in loop, 'cause it has only 8 fields, so you can easily collect all necessary fields from values_tab and pass them as dynamic fieldstring.
If you wanna use alias CUOBJ for your dynamic field you should add it like this:
LOOP AT values_tab INTO value.
DATA(aliased_value) = value-instance && ` AS cuobj `.
SELECT (aliased_value)
...
Remember, that your alias should exists among ibsymbol fields, otherwise in case of static ibsymbol_tab declaration this statement will throw a short dump.
I am trying to grab a couple values from an sqlite database, but instead of returning the value I am SELECT-ing, it is returning that value in an array inside of another array.
My code:
def self.find(id, database_connection)
name = database_connection.execute("SELECT name FROM pokemon WHERE id = ?", id)
type = database_connection.execute("SELECT type FROM pokemon WHERE id = ?", id)
pokemon_inst = Pokemon.new(id: id, name: name, type: type, db: database_connection)
end
The Problem:
When I run pry.binding
name outputs [["Pikachu"]]
type outputs [["electric]]
Is this working correctly? I can't imagine I should I just be calling name[0][0] to access the data, right?
The execute() method wraps everything it is returning in an array, and each database row is placed in an array. So, for the single value being queried to be in two arrays is correct.
Since everything is working as it should I will be adjusting my code to this:
def self.find(id, database_connection)
pokemon = database_connection.execute("SELECT * FROM pokemon WHERE id = ?", id).flatten
name = pokemon[1]
type = pokemon[2]
pokemon_inst = Pokemon.new(id: id, name: name, type: type, db: database_connection)
end
The adjustments are to flatten the array when it is assigned the queried data and to assign the individual values from that array.
Is possible do Select * form DynamicValue to perform a query like this in Navision?
Thanks in advance
To perform a sql query li this select * from DynamicValue You must do something like this.
Imagine that you have a table and you are going to show the data in a page or form.
Variables:
RecDynamicValue (Table).
PagDynamicValues (Page).
Code:
RecDynamicValue.RESET; //Clean filters
CLEAR(PagDynamicValues);
PagDynamicValues.SETTABLEVIEW(RecDynamicValue); //Set RecDynamicValue (Table)
PagDynamicValues.RUN; (Open Page)
In this code when page is open you can see al records from DynamicValue table like a Select * from DynamicValue.
If you need perform a loop for all records from DynamicValue table in code try this:
RecDynamicValue.RESET;
IF RecDynamicValue.FINDSET THEN REPEAT //Repeat clausule for a loop
//Loop...
//Loop...
//Loop...
UNTIL RecDynamicValue.NEXT = 0; //Repeat until last value
In all cases first you need declare a variable, SubType = Record and specified ID or name of record.
You can not change the value of the table variable by code.
But perhaps you can use RecordRef function to do that.
For example:
RecRef.OPEN(27); //Id of ItemTable
RecRef.FINDFIRST;
FldRef := RecRef.FIELD(3); // Item.Description;
FldRef.VALUE('New description');
RecRef.MODIFY;
In your case your DynamicValue is parameter to RecRef.OPEN("Your Dynamic Value") here you need specified value ID of your table.
You can also perform a loop using RecorRef.
I have a database as below:
TABLE_B:
ID Name LISTID
1 NameB1 1
2 NameB2 1,10
3 NameB3 1025,1026
To select list data of table with ID. I used:
public static List<ListData> GetDataById(string id)
{
var db = Connect.GetDataContext<DataContext>("NameConnection");
var sql = (from tblB in db.TABLE_B
where tblB.LISTID.Contains(id)
select new ListData
{
Name= tblB.Name,
});
return sql.ToList();
}
When I call the function:
GetDataById("10") ==> Data return "NameB2, NameB3" are not correct.
The data correct is "NameB2". Please help me about that?
Thanks!
The value 10 will cause unintended matches because LISTID is a string/varchar type, as you already saw, and the Contains function does not know that there delimiters that should be taken into account.
The fix could be very simple: surround both the id that you are looking for and LISTID with extra commas.
So you will now be looking for ,10,.
The value ,10, will be found in ,1,10, and not in ,1025,1026,
The LINQ where clause then becomes this:
where ("," + tblB.LISTID + ",").Contains("," + id + ",")
