I need to check and see if a validation rule exists on a table and/or field in FoxPro (to determine programmatically if it should be replaced/added/removed). DISPLAY STRUCTURE doesn't include any validation rules.
Is there a VFP command to list out validation rules on a table (to an array, file, cursor, anything)?
I found that AFIELDS() and COPY STRUCTURE EXTENDED both include field and table validation rules.
For AFIELDS() the table expression is stored on the first row of the array in column 10, and the field validation expression is stored with each row in column 7.
For COPY STRUCTURE EXTENDED the table expression is in the first row in a memo column called table_rule and the field expression is stored with each rule in a memo column called field_rule.
You can use DBGETPROP to get information for a single DB-object/field:
? DBGETPROP("mytable.myfield","Field","RuleExpression")
or for a table:
? DBGETPROP("mytable", "Table", "RuleExpression")
Another option is to use the GenDBC utility that comes with VFP. It generates a program that recreates the database.

How to add rows to an Excel table inside a loop after the columns are mapped?
I tried the "Add rows to an Excel table" step, but I can't grab the values from Column1 and Column2 on the "Select" step above.
This should be easy, I guess, but I can't make it.
Thank you,
Your "Select" actions looks like it might be missing something, seems like it will add the whole item to "Column1" and duplicate that for "Column2". If your value is an array but it is not being recognized as so, you can use the "Parse JSON" action, or the json() expression you should be able to select the keys that you want to use for each column.
I might need more details to see the exact issue with your flow, but in the meantime try this:
Parse JSON action
Here the "Initialize variable" will be your blob storage result.
In the Parse JSON, add you blob storage value
In the "Select" action use the body output of the "Parse JSON" action
You should be able to select the specific values you want in your columns
json() expression
The parameter will be your blob storage. In my example is my string variable sown in the image.
Since the "Select" action returns an array as a result, the next step you should use is the "Apply to each" action
The new values mapped in the "Select" action should be available to be used here, if for any reason they are not (it is common for power automate to have issues like this) you can use an expression to get the value
items('Apply_to_each')?['columnName']
Note that the "Apply_to_each" inside "items" will be different if you rename this action.
Then, you'll have your Excel file with all the rows added to the table you selected.
Is it possibly to modify certain rows of the output table in a SAP infoset query? If yes, how? I already tried writing some code for that in the coding tab in the infoset (at the end of selection - after the list) but I was not able to reference the table or fields.
I have a grid where the user can select records via checkbox in front of every record. Now I have a requirement to sort the records based on their selection, so that all selected records should be placed top, followed by the not selected ones.
Is there any standard function to achieve this? As an alternative I thought of saving the selection state as an attribute on every record and sort based on the attribute.
The code for the column is:
gridRealmDt.setSelectionType(SelectionStyle.SIMPLE);
gridRealmDt.setSelectionAppearance(SelectionAppearance.CHECKBOX);
I try to describe the code I use as the affected code is deeply nested in our own framework classes.
gridRealmDt is a subclass of smartgwt ListGrid. In my Dialog a create an instance of the grid which creates an instance of a database bound datasource. When the dialog is loaded the records are fetched from the database and after that a registered an dataArrivedHandler where I select the records which match records from another table.
I tried to place the selection attribute in an extra field and use that for sortig before my other sort criteria, but this does not work. Here is the code for the field I am using.
ListGridField txtSelected = new ListGridField(SELECTED, "");
txtSelected.setHidden(true);
txtSelected.setSortByDisplayField(true);
txtSelected.setCanSortClientOnly(true);
When I do not set the canSortClientOnly property the order by is sent to my database resulting in an error, as the table does not contain that field, so I set the property. Now I get following error
Removing field from the sort Specifier array because it specifies canSort Client Only: true and all data is not yet client-side.
I also tried to use a sortNormilizer on the Name field which is my main sort criteria, but the normalizer is called before the selection value is set to the record.
record.setAttribute(CARealmDS.SELECTED,selected ? "a" : "b");
I also cannnot find a way to call the normalizer when selection changes.
Currently we are using Smart GWT Version 6.0p.
I don't think there is any standard function. Just use grid store update. Place checked items first.
I am loading data into Spotfire report from Oracle using view. In the Spotfire Prompt when the text value is entered, whether it is Upper,lower or mixure of both the relative column values should be displayed. Since this is done at the data base level i need some way to make the column values case insensitive.
I know that column values can be converted to upper/lower case with upper()/lower() function but i need a way so that even a mixure of upper/lower cases will search the column values.
I found one more solution for session :
alter session set NLS_COMP=ANSI;
alter session set NLS_SORT=BINARY_CI;
After using the above code any SQL search for column will be case insensitive. but i need a solution where i can use it in the view of the column element.
Does the inputted value need to be a prompt? It would be possible to do this using a parameter (which could be set by a document property/ input field/ configuration block).
Within the SQL for your query, you could add a where clause something like
upper(A1."mycolumn")=upper(?myParameter)
After refreshing the parameters section of the information link ‘myParameter’ will appear. The information link can then be added as an on demand table, with myParameter being set via a document property.
i have a strange user request: they want to be able to say for every fields in every forms from where they get information used to compile it.
value must be selected from a list
essentially iam looking a way to avoid to double the fields.
one way can be add a M:M table where link field-name and information-source
but using this for retrive from real data table only fields derived from an info-source can be really bad
EDIT
to be more clear the solution i want to avoid is to have a data table like this:
fieldname1
fieldname1Origin
fieldname2
fieldname2Origin
fieldname3
fieldname3Origin
...
but i do the link table in this way:
FieldName
OriginId
i have to map oll field names and to search in it with string name when i need to query data table i have to do something like this
select
case when (exists select 1 from LinkTable where FieldName='fieldname1' AND
OriginId=SelectedID) then fieldname1
else NULL
end
for every fields
What about mixing several controls, such as a combobox with all lines, that would trigger the display of all columns of that line.
Something like that (I am currenlty working on that project):
