I'm trying to figure out how to do a query with a where blah=blah or blah=blah2 with subsonic 3 linq and I can't figure it out. My query at the moment looks like this:
var ddFaxNumbers = from f in rf_faxnumber.All().Where(f => f.assigned == null).Where(f => f.location == currentFaxNumberRecordData.location)
select f;
This is a page with an update panel where when the user clicks edit I display 2 dropdowns, one for location, and one for the phone numbers. The current phone number is assigned, and marked so in the database table, so when I try to bind the dropdown it throws an error since the results don't contain the currently assigned number. I need to be able to query the table like so:
select * from numbers where assigned == null or number == currentnumber and location=selecteLocation. What I can't figure out in the SS syntax is how to do the OR part of the query. I don't see an .or, so is this even possible? Thanks for your help in advance.

You should be able to just do:
var ddFaxNumbers = from f in rf_faxnumber.All()
where (f.assigned == null || f.location == currentFaxNumberRecordData.location)
select f;

I've been struggling to make it work. I have a dataset with column Country and each record has its own country. I've also created a parameter #Country which is a blank input. What I want to do is to show all records from dataset if parameter is left empty and show records matching country when it is given by user. So far everything works whenever I input a country BUT when I leave it blank then no records are being shown. How can I fix it?
Snippets of code I've tried, ever one with the same result.
FILTER('Dataset', ISBLANK(#Country) || 'Dataset'[Country] = #Country))
FILTER('Dataset', IF(ISBLANK(#Country), 1, 'Dataset'[Country] = #Country))
FILTER('Dataset', IF(ISBLANK(#Country), 'Dataset'[Country], 'Dataset'[Country] = #Country))
FILTER('Dataset', IF(NOT(ISBLANK(#Country)), 'Dataset'[Country] = #Country, 1))
I have a sql server database table with columns as shown below :

I cannot figure out how I can group only zeros listed for EPID and group only ones in my query ? Can anyone point me out how I can solve this ?
Looks like you're trying to query for (EPID=='A' AND isRequired==1) OR EPID=='B', is that right? Here's a guess:
SELECT *
FROM <table>
WHERE (EPID = 'A' AND isRequired = 1)
OR (EPID = 'B');
I'm creating a report table type calendar where users can create back up by date select a filter that would filter out the table values depending on the user selected. (i.e. if they choose user1, then only back ups with user1 will show up)
I would like it to be when P106_BACK_UP_BY_USER = 0, the table shows all the values (aka getting rid of the "where" portion of the query.
Thank you for your help!
I'm having issues with trying to allow the user to see all the back ups of the table again (getting rid of the filtered value). My current query is this:
I would like it to be when P106_BACK_UP_BY_USER = 0, the table shows all the values (aka getting rid of the "where" portion of the query.
Thank you for your help!
You can use case when statements in your query's where condition as follows:
select *
from my_table
where my_table.created_by =
(select user_name from my_table2 where app_users_id =
case :P106_BACKUP_BY_USER when 0 then app_users_id
else :P106_BACKUP_BY_USER
end)
And for getting better help, please paste your code as text not as an image next time.
This should work too:
...
WHERE b.active_server = s.server_id
AND (:P106_BACK_UP_BY_USER = 0 OR
UPPER(b.created_by) =
(SELECT UPPER(user_name)
FROM eba_bt_app_users
WHERE app_users_id = :P106_BACK_UP_BY_USER
)
);
I have an interactive grid with a bunch of records, and I want to set up a button on the page that changes one column in all records currently selected.
Running APEX 18.2, the IG has a whole bunch of columns and I want to change just one of them, but on a whole bunch of rows, so I do need a button.
The IG has ROWID as PK because the actual PK is assembled from 4 different columns.
I have spent some time googling this issue and have found a couple people with solutions:
http://thejavaessentials.blogspot.com/2017/03/getting-selected-rows-in-oracle-apex.html
This is the first, and simplest solution. But it doesn't return any rowid or anything like that, it returns the value in the first column.
Then I also found
http://apex-de.blogspot.com/2018/09/update-several-rows-in-tabular-form-grid.html
and
https://ruepprich.wordpress.com/2017/03/23/bulk-updating-interactive-grid-records/
Which are pretty similair and seem to be the best for me, but I get a Javascript error in the console: http://prntscr.com/n5wvqj
And I dont really know much Javascript, so I dont know what went wrong or how to best fix it.
I set up a Dynamic action on button click that executes Javascript and I have the selected element being the region named CUR_STAT.
var record;
//Identify the particular interactive grid
var ig$ = apex.region("CUR_STAT").widget();
//Fetch the model for the interactive grid
var grid = ig$.interactiveGrid("getViews","grid");
//Fetch the model for the interactive grid
var model = ig$.interactiveGrid("getViews","grid").model;
//Fetch selected records
var selectedRecords = apex.region("CUR_STAT").widget().interactiveGrid("getViews","grid").view$.grid("getSelectedRecords");
//Loop through selected records and update value of the AVT_OBR column
for (idx=0; idx < selectedRecords.length; idx++)
{
//Get the record
record = model.getRecord(selectedRecords[idx][0]);
// set Value for column AVT_OBR on "D"
model.setValue(record,"AVT_OBR", 'D');
}
The column named AVT_OBR is a select list with display values(DA, NE) and return values(D, N). But I tried having it be a text field and it didnt help.
I want to be able to select multiple columns and change the data in those entries.
If possible I would also like to be able to change data in such a way in a hidden column. Or if I could get all the ROWIDs for selected records and execute a PLSQL block with them.
Ended up with noone responding so I spent a lot of time and finally came up with a solution.
var g = apex.region('myIG').widget().interactiveGrid('getViews','grid');
var r = g.getSelectedRecords();
for(i = 0; i < r.length; i++) {
g.model.setValue(r[i], 'myColumn', 'Value');
}
For some reason none of the solutions I found had worked. But I learned from those solutions and made this simple piece of code that does what I need.
Also, I was wanting to set up so I could do this set value on a hidden column, I achieved this by just having the column visible and editable, but then when running the page I clicked on the column and hid it, and set the current view as the default report.
If anyone stumbles upon this question, I hope it helps.

var ctx = new ServiceContext(...);
var result1 = (from f in ctx.CreateQuery<aEntity>()
where f.field1 == "x"
select new { f.Id, f.field2 }).ToList();
var result2 = (from f in ctx.CreateQuery<aEntity>()
where f.field1 == "x"
select f.field1).First();
result2 returns null! After adding f.field1 to the select clause in the first query result2 returns "x". It looks like a internal columnset is created and used in the context of the second call. Looking at the SQL Server trace of both calls we see the expected select-from queries based on the C# code. The returned second result is not expected. Can someone explain this behaviour?
As for me it looks like a caching functionality and it's on the side of CRM because as you mentioned SQL queries were correct. I had the same issue in my applications when tried to make two consecutive queries for the same entity record but selected two different fields, the second request always returned NULL. Here are workarounds that I use when work with the ServiceContext:
Simple one: always retrieve an entity with all fields (without select statement) (even if I want it or not)
or create a service context with disabled caching
Right now I try to use the ServiceContext as less as possible replacing it with QueryBase expressions (even if I love to use LINQ).
Keep in mind LINQ CRM driver implementation is a subset of SQL only.
Could you try something like this?
var result1 = (from f in ctx.CreateQuery<aEntity>()
where f.field1 == "x"
select new CustomClass {
Id = f.aEntityId,
Field2 = f.field2
}).ToList();
You can have complex queries if you want, but you need to know what can be done and what can't be done.
Id property is not always returned by the driver, but the entity's primary key is, which is normally the entity logical name + "Id".
