I'm stading infront of a problem I'm unable to wrap my head around.
I have a table with an unknown numbers of columns and want to be able to enable sorting on some columns.
As for itself, not a big deal by using:
"columnDefs": [
{ "targets": 0, "orderable": false }
{ "targets": 1, "orderable": true }
{ "targets": 2, "orderable": false }
]
however, in my case I have a table with a dynamic numbers of columns (between 5 and 15 columns, generated per page load depending on some parameters).
this solution does not work when I use it on a target, that doesn't exist. So just writing this { "targets": N, "orderable": false } 15 times won't do the job and wont look very good either.
Is there a way to disable all ordering BUT one column?

I want to display min, max and average of the same data field. Tried the designer on demo page and it is not possible to add same column into Values list, nor is it possible to check multiple aggregation functions in the dropdown.
I tried to edit report JSON manually, but this doesn't seam to be supported:
"measures": [
{
"uniqueName": "myvalue",
"aggregation": "min"
},
{
"uniqueName": "myvalue",
"aggregation": "max"
},
You can add multiple aggregations with the calculated values option, e.x.
"measures":[
{
"uniqueName": "Min myValue",
"formula": "min('myValue')",
},
{
"uniqueName": "Max myValue",
"formula": "max('myValue')",
}
Also, you can find the "Add calculated value" button on the top of the Fields List window. It allows creating calculated values in runtime using UI tools.
You can find more examples with calculated values here
I'm working on a google sheets integration project where I'd like to add formatted text to cells (bold, italic). This needs to be for only part of the cell (e.g. only some of the text in the cell is bold ) I can see that this can be done though the CellData object, documented in the sheets api here:
CellData
But I can't work out how to get an instance of these objects. I'm using the sheets service to successfully get a SpreadSheet, Sheet and ValueRange objects, but I can't work out how to get through to the cell data objects themselves to use these methods.
When a part of value of a cell has several formats, you want to retrieve the formats.
You want to put a value with several formats to a cell.
I understand your question as above. If my understanding is correct, how about these samples?
1. Retrieve value
When a part of value of a cell has several formats like below image,
the script for retrieving the values with the formats is as follows.
Sample script:
This sample script retrieves the value from the cell "A1" of "Sheet1".
spreadsheet_id = '### spreadsheet ID ###'
ranges = ['Sheet1!A1']
fields = 'sheets(data(rowData(values(textFormatRuns,userEnteredValue))))'
response = service.get_spreadsheet(spreadsheet_id, ranges: ranges, fields: fields)
Result:
{
"sheets": [
{
"data": [
{
"rowData": [
{
"values": [
{
"userEnteredValue": {
"stringValue": "abcdefg"
},
"textFormatRuns": [
{
"format": {}
},
{
"format": {
"fontSize": 24,
"foregroundColor": {
"red": 1
},
"bold": true
},
"startIndex": 2
},
{
"format": {},
"startIndex": 5
}
]
}
]
}
]
}
]
}
]
}
2. Put value
When a value with several formats is put to a cell, the script is as follows.
Sample script:
This sample script puts the value to the cell "B1" of "Sheet1". As a sample, update_cells is used for this situation.
spreadsheet_id = '### spreadsheet ID ###'
requests = {requests: [
update_cells: {
fields: 'userEnteredValue,textFormatRuns',
range: {sheet_id: 0, start_row_index: 0, end_row_index: 1, start_column_index: 1, end_column_index: 2},
rows: [{values: [{user_entered_value: {
string_value: 'abcdefg'},
text_format_runs: [{format: {}}, {format: {font_size: 24, foreground_color: {red: 1}, bold: true}, start_index: 2}, {format:{}, start_index: 5}]
}]}]
}
]}
response = service.batch_update_spreadsheet(spreadsheet_id, requests, {})
About sheet_id: 0, if you want to other sheet, please modify it.
Result:
Note:
These sample scripts supposes that your environment can use Sheets API.
These are simple samples. So please modify them to your situation.

I create a view with Map function:
function(doc) {
if (doc.market == "m_warehouse") {
emit([doc.logTime,doc.dbName,doc.tableName], 1);
}
}
I want to filter the data with multi-keys:
_design/select_data/_view/new-view/?limit=10&skip=0&include_docs=false&reduce=false&descending=true&startkey=["2018-06-19T09:16:47,527","stage"]&endkey=["2018-06-19T09:16:43,717","stage"]
but I still got:
{
"total_rows": 248133,
"offset": 248129,
"rows": [
{
"id": "01CGBPYVXVD88FPDVR3NP50VJW",
"key": [
"2018-06-19T09:16:47,527",
"ods",
"o_ad_dsp_pvlog_realtime"
],
"value": 1
},
{
"id": "01CGBQ6JMEBR8KBMB8T7Q7CZY3",
"key": [
"2018-06-19T09:16:44,824",
"stage",
"s_ad_ztc_realpv_base_indirect"
],
"value": 1
},
{
"id": "01CGBQ4BKT8S2VDMT2RGH1FQ71",
"key": [
"2018-06-19T09:16:44,707",
"stage",
"s_ad_ztc_realpv_base_indirect"
],
"value": 1
},
{
"id": "01CGBQ18CBHQX3F28649YH66B9",
"key": [
"2018-06-19T09:16:43,717",
"stage",
"s_ad_ztc_realpv_base_indirect"
],
"value": 1
}
]
}
the key "ods" should not in the results.
What did I do wrong?
Your query is not multi-key .. ist start and endkey.
if you want to have results by dbname in a special time range.. you need to change the emit to [doc.dbName,doc.logTime,doc.tableName]
then you query startkey=["stage","2018-06-19T09:16:43,717"]&endkey=["stage","2018-06-19T09:16:47,527"]
(btw. are you sure that your timestamp is in the right order ? In your example the second TS is larger than the first..)
As you have chosen a full date/time stamp as the first level of your key, down to millisecond precision, there are unlikely to be any repeating values in the first level of your compound key. If you indexed just the date, say, as the first key, your date would be grouped by date, dbame and table name in a more predictable way
e.g.
["2018-06-19","ods","o_ad_dsp_pvlog_realtime"]
["2018-06-19","stage","s_ad_ztc_realpv_base_indirect"]
["2018-06-19",stage","s_ad_ztc_realpv_base_indirect"
["2018-06-19","stage","s_ad_ztc_realpv_base_indirect"
With this key structure, the hierarchical grouping of keys works in your favour i.e. all the data from "2018-06-19" is together in the index, with all the data matching ["2018-06-19","stage"] adjacent to each other.
If you need to get to millisecond precision, you could index the data as follows:
function(doc) {
if (doc.market == "m_warehouse") {
emit([doc.dbName,doc.logTime], 1);
}
}
This would create index organised by dbName, but with a secondary sort on time. You can then extract the data for specified dbName between two timestamps.
I'm trying to create a GSI on a table with 30 columns (using ruby SDK). I use the projection_type: 'ALL' - but I still get the following exception:
Aws::DynamoDB::Errors::ValidationException: One or more parameter values were invalid: Number of projected attributes in all indexes exceeds limit of 20, number of projected attributes:30
As far as I read, this should only happen when using the INCLUDE projection_type:
This limit does not apply for secondary indexes with a ProjectionType of KEYS_ONLY or ALL.
http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Limits.html#limits-secondary-indexes
The create statement looks something like:
connection.update_table({
table_name: "my-table", # required
attribute_definitions: [
{
attribute_name: "indexDate",
attribute_type: "S",
},
{
attribute_name: "createdAt",
attribute_type: "S",
},
],
global_secondary_index_updates: [
{
create: {
index_name: "my-new-index", # required
key_schema: [
{
attribute_name: "indexDate",
key_type: "HASH",
},
{
attribute_name: "createdAt",
key_type: "RANGE",
},
],
projection: { # required
projection_type: "ALL"
},
provisioned_throughput: { # required
read_capacity_units: 10, # required
write_capacity_units: 300, # required
}
}
}
]
})
Turned out that the attribute limit restriction goes across all GSI's on the table. I had another one that caused this one to fail. Deleted that one, and then it worked.

What I get is
{
"status": 0,
"data":

"agence": "CTM"
},
{
"secteur": "Essaouira",
"agence": "CTM"
},
{
"secteur": "Essaouira",
"agence": "Gare Routiere Municipale"
}
]
}
What you want is not possible with JPQL.
What does Group By do?
It combines all rows that are identical in the columns in the group by clause in to one row. Since it combines multiple rows into one, data in other columns can only be present in some combined fashion. For example, you can include MIN/MAX or AVG values, but never the orginal values.
Also the result with always be a table, never a tree.
Also note: there is no duplicated data. Every combination of secteur and agence appears exactly once.
If you want a tree structure, you have to write some java code for that.
