I have created a Virtual StringTreeview component with multiple columns. Most columns including the primary [0] column are set as coEditable = true. I have a set up a test with 20 nodes. Once started I can successfully edit the primary column for multiple nodes provided I point to the primary column to pick it. However, once I have selected another node by pointing at another column, I can no longer edit the primary column text on any node. When I select a new row pointing to the primary column, the focus shifts to the selected row, but the previous column used is highlighted instead of the primary column just selected. IF I select a row using any other column, the focus shifts to the correct column and I can edit the string.
TreeOptions.EditOPtions is set to toDefaultEdit. IN addition, the column also contains an image (although I do not see how that changes anything).
Can anyone shed light on any additional settings required or steps I have missed to control focus properly?
EDIT: Added current settings
VStringTree Options:
Auto Options = [toAutoDropExpand,toAutoScrollOnExpand,toAutoSort,toAutoTristateTracking,toAutoDeleteMovedNodes,toDisableAutoscrollOnFocus,toAutoChangeScale]
Edit Options = toDefaultEdit
Selection Options = [toExtendedFocus]
Misc. Options = [toEditable,toFullRepaintOnResize,toInitOnSave,toToggleOnDblClick,toWheelPanning,toEditOnClick]
String Options = [toSaveCaptions,toAutoAcceptEditChange]
Header Options:
[hoColumnResize,hoDblClickResize,hoDrag,hoHotTrack,hoShowSortGlyphs,hoVisible]
Column Options:
[coAllowClick,coEnabled,coParentBidiMode,coParentColor,coResizable,coShowDropMark,coVisible,coEditable]

Picture linked below as this is a bit tangled:
I am working with a data set that has "nested" values. There are three different types of entries: categories, then subcategories that are nested under the categories, then individual items that are nested under the subcategories (picture linked below). The entries are matched up using a filter system. Column A has the entry type, column B has the actual value, column C has the filter. The filter is always the value of entry you are nesting under. So, for a subcategory entry, Column A= "Subcategory", Column B= [name of subcategory] Column C = Column B of the category type entry above (the name of category it belongs to).
I need a way to automatically fill in the filters.
The way I am thinking I could do this is to search Column A (moving up) for the first instance of the entry type I need, and then return the value of the Column B cell in that row. Is this possible?
Given your exact data above (looking only at A14:C), delete everything from C14:C (including the header) and place the following formula in C14:
=ArrayFormula({"FILTER"; IF((A15:A="") + (A15:A="Category"),, IF(A15:A="Subcategory", VLOOKUP(ROW(A15:A), FILTER({ROW(A15:A), B15:B}, A15:A="Category"), 2, TRUE), VLOOKUP(ROW(A15:A), FILTER({ROW(A15:A), B15:B}, A15:A="Subcategory"), 2, TRUE)))})
This will create the title (which you can edit within the formula itself as you like) and all results for non-null rows thereafter.
You'll need to adjust the 15 in ranges to whatever the starting row of your non-header data actually is in your sheet.
I think this surely must be a simple thing to achieve, but I have tried various appends and merges and can't seem to get it right.
I have two files, one titled 'Previous' and one titled 'Current'. Both show near identical data, like so :
ID Status Date_Changed
1 Closed 10/11/21
2 Open 10/01/21
3 Closed 10/03/21
4 Pending 10/15/21
I'd like to merge both files together, but retain all columns so that it is structured as below. This will allow me to show tables of what has changed etc.
ID Previous.Status Current.Status Previous.Date_Changed Current.Date_Changed
1 Closed Open 10/11/21 10/15/21
2 Open Closed 10/01/21 10/15/21
3 Closed Pending 10/03/21 10/14/21
I am aware this is probably due to my own naivety with PowerBI. I have tried combining the data by connecting to the folder, but that seems to create a new dataset with the data stacked on top (ie with duplicate ID values). I tried using merge queries as new and joiningby ID, but that didn't seem to give me the right output either?
You can start from the Current table and merge in the previous table joining on ID and then expand the columns. Rename and reorder columns as desired.
Here's an example you can paste into the Advanced Editor:
let
CurrentSource = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUfIvSM0DUoYG+oam+kYGRoZKsTrRSkZAIeec/OLUFEw5Y6BQQGpeSmZeOlTSBCFpglMyFgA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [ID = _t, Status = _t, Date_Changed = _t]),
Current = Table.TransformColumnTypes(CurrentSource,{{"ID", Int64.Type}, {"Status", type text}, {"Date_Changed", type date}}),
PreviousSource = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUXLOyS9OTQEyDA30DQ31jQyMDJVidaKVjIBC/gWpeRAZAyQZYzRdBsYIOROgUEBqXkpmXjrUSFOoZCwA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [ID = _t, Status = _t, Date_Changed = _t]),
Previous = Table.TransformColumnTypes(PreviousSource,{{"ID", Int64.Type}, {"Status", type text}, {"Date_Changed", type date}}),
#"Merged Queries" = Table.NestedJoin(Current, {"ID"}, Previous, {"ID"}, "Previous", JoinKind.LeftOuter),
#"Expanded Previous" = Table.ExpandTableColumn(#"Merged Queries", "Previous", {"Status", "Date_Changed"}, {"Previous.Status", "Previous.Date_Changed"}),
#"Renamed Columns" = Table.RenameColumns(#"Expanded Previous",{{"Status", "Current.Status"}, {"Date_Changed", "Current.Date_Changed"}}),
#"Reordered Columns" = Table.ReorderColumns(#"Renamed Columns",{"ID", "Previous.Status", "Current.Status", "Previous.Date_Changed", "Current.Date_Changed"})
in
#"Reordered Columns"
Note: I've defined Previous within the query above so that it's self-contained. Ordinarily, it would be a separate query.
You can try the following steps:
create a new column called "Source Name" in each table with a constant value mentioning if the data if from "Previous" or "Current"
Then append both the table in Power Query. This will still stack both the tables on top of each other.
But now you can use the "Source Name" column to differentiate them in the Matric Visual. You can add a Matrix visual with
"Source Name" in the Column Field
"Date" & "Status" in values field
"ID" in Rows field
This is ideal because you get all the data in a tabular format which will help you in further calculations if necessary
You can check out an example screenshot below:
I used the 'Lookup Wizard' to try and create a drop-down list to show the IDs stored in another table, I need the drop-down to also list the employee name so I know what number to select, all of that works, however, when I select the item I need it returns the employee name, not the number. I am new to Access and I hope there is a simple solution for this.
Set the Column Widths property to: 0;1"
This will hide the first column whilst still retaining the link between primary & foreign keys.
I fixed it! I had to switch the select statement to: SELECT [Employee Info].[Vendor ID], [Employee Info].[Employee Name]
For the following table:
I run the following stored procedure:
I'm redirected to "Results" tab and seeing nothing. Then if I click on "refresh" icon (below Results tab), then I get the dialog saying:
SQLCODE = -625 validation error for column ID, value "* null *"
And of course, nothing is added...
As far as I understand, firebird expects somevalue for RC_ID (which is my PK and should principally automatically incremented). If I give value also for RC_ID, it is working well.
So, what should I do to make a clear "insert" without these errors?
The problem is that you are not setting a value for the primary key. Contrary to your expectation, primary keys are not automatically incremented. This is the case in any database I'm aware of. You always need to mark it as an identity, auto increment or generated, or something else to get that behavior, although some tools (table builders) may already apply this for you by default.
If you are using Firebird 3, you can define your column as GENERATED BY DEFAULT AS IDENTITY (see Identity Column Type in the Firebird 3 release notes). For earlier Firebird versions the best way is to define a sequence (also known as generator) with a before insert trigger that populates the primary key column.
For more details on how to define an identity column (or define the trigger), see my answer on this question: Easiest way to create an auto increment field in Firebird database.
In firebird, the autoincrement was not working like in MySQL. Thus, sending a value for RC_ID was a must...
I found some working examples based on idea:
create a generator
assign it to column (PK)
call GEN_ID with that generator like this:
:
begin
insert into RESERVATIONCATEGORY (RC_ID, RC_NAAM)
values (
GEN_ID(GEN_RESERVATIONCATEGORY _ID,1), 'selam'
);
suspend;
end
I am using master-detail connection to show a list of assigned columns of a detail-table. In addition i want to show a second grid with not assigned detail columns
Example
Master-Table t_human: idHU, nameHU (like John, Oscar, ...)
Detail-Table t_property: idPO, namePO (like male, female, blond hair, beard, blue eyes ...)
Join-Table t_hu_po: idHU, idPO
-> John - male, blond hair
-> Oscar - male, blue eyes, beard
When i select a master table row i want to show the assigned porperties and also the not assigned ones. The master-detail for the assigned properties works fine.
But for the not-assigned properties doesn't work.
Detail-SQL:
select p.idPO, p.namePO
from t_property p
where not exists (select * from t_hu_po hp where hp.idHU = :idHU and hp.idPO = p.idPO)
Master-SQL:
select idHU, nameHU from human
When i try to select the detailfield in the delphi component (Devart, SDAC, TMSQuery) it only shows me the fields for p.idPO and p.namePO. The :idHU parameter in the statement is configured as parameter for the query in the component. When i manually type the idHU in the DetailFields property of the Dataset (TMSQuery) i get an Invalid column name 'idHU'.. from delphi when activating the query.
Does someone knows a better solution than doing it with events for datachange and manually setting the detail-parameter and refreshing the detail-query.
My thought was, that master-detail would do the same thing but only in background, so that i don't have do code it.
Thanks
Stephan
Instead of using the where not exists try where p.idPO not in (Select idPO from t_hu_po where idHU=:idHu)
By makinge the subquery simply return all the idPOs that exist for the selected idHu, your query now looks for the properties that are not in that list.
