Protect='0' mean not protected
Protect='1' means protected

you are inserting 2 blank rows too. and not sure what are the primary key columns

THANK YOU SO MUCH YOU SAVED MY LIFE AND I WILL GET HIRED

this script "dw_article.ResetUpdate() " solved the issue

thank you so much

can i ask for one more last help ?? i want to get a messagebox directly if i enter a reference(PK) that already exists before submitting the form and after i clicked the "new" button

here is the script of "new" button

char reference
dwc_article.scrolltorow(dwc_article.insertrow(0))

// Scroll to the newly inserted row
long ll_new_row
ll_new_row = dwc_article.InsertRow(0)
dwc_article.ScrollToRow(ll_new_row)


// Get the current date
date ld_date_creation
ld_date_creation = today()

string ls_formatted_date
ls_formatted_date = String(ld_date_creation, "yyyy-mm-dd")

// Set the current date to the "date_de_creation" column
dwc_article.SetItem(ll_new_row, "date_de_creation", ls_formatted_date)




dwc_article.modify("reference.Protect='0'") // This removes input capability from all columns
	   dwc_article.modify("name.Protect='0'")
	   dwc_article.modify("prix.Protect='0'")
		 dwc_article.modify("date_de_creation.Protect='1'")

how to check if the PK is unique or not cause when i created the table in DB it didnt ask me and no it's no auto increment

i think my error in "update" or "save update" buttons. here is the script of both of them. please help i need this to get hired

this is the script of "update" button

long ll_row
ll_row = dwc_report.GetSelectedRow(0) // Get the selected row index in dwc_report


if ll_row >= 0 then // If a row is selected
    // Clear existing data in dwc_article
    dwc_article.Reset()
	 
	 long ll_nextRow
    ll_nextRow = dwc_article.RowCount() + 1

    // Copy data from dwc_report to dwc_article
    dwc_report.RowsCopy(ll_row, ll_row, Primary!, dwc_article, ll_nextRow, Primary!)

    // Disable all inputs in dwc_article
    dwc_article.modify("reference.Protect='1'") 
    dwc_article.modify("name.Protect='0'")
    dwc_article.modify("prix.Protect='0'")
    dwc_article.modify("date_de_creation.Protect='1'")

    // Retrieve data in dwc_article to reflect changes
    //dwc_report.retrieve()
	//dwc_article.retrieve()
else
    MessageBox("No row selected", "Please select a row in the report")
end if

and this is the script of "save update" button

// Declare variables
string ls_reference, ls_name
string ls_date_de_creation
decimal ld_prix
date ldt_date_de_creation

// Retrieve data from dwc_article
ls_reference = dwc_article.GetItemString(1, "reference")
ls_name = dwc_article.GetItemString(1, "name")
ld_prix = dwc_article.GetItemNumber(1, "prix")
ls_date_de_creation = dwc_article.GetItemString(1, "date_de_creation")

if Len(ls_date_de_creation) > 0 then
  ldt_date_de_creation = Date(ls_date_de_creation) // Adjust the format as per your DataWindow's date format
end if

// Perform the update operation
UPDATE gest_article
SET name = :ls_name,
    prix = :ld_prix,
    date_de_creation = :ldt_date_de_creation
WHERE reference = :ls_reference;

// Check for SQLCA.SQLCode to handle errors if necessary
if SQLCA.SQLCode <> 0 then
    MessageBox("Update Error", SQLCA.SQLErrText)
else
    MessageBox("Update Successful", "Record updated successfully.")
end if
dwc_report.retrieve()

Hi, Hatem -

Do you perform a dw_article.ResetUpdate() after a successful dw_article.Update() call to reset the DataWindow's row and column status flags?

Do you have any triggers on the gest_article table that could be affecting this behavior?

You may wish to trace and analyze the commands issued to the database by temporarily connecting to the database via SQLCA.DBMS = "TRACE ODB" instead of the normal SQLCA.DBMS = "ODB", to see if that gives you some additional insight as to what is happening.

Best regards, John

Hi Hatem;

  What you need to check is that the value of the Primary key is unique in the DWO or if the PK is "Auto increment" that your DWO is not trying to update it as the DBMS would then want to do that instead.
