Display an alert message with Dynamic action if the user type the same value for an item with the same value in the table

Christian Pitet 229 hours ago

Hi,

Under Oracle APEX 24.2.9, I want to display an alert message in a form if the user type the same value for an item in the table.

The item is in application 108 p. 24 and is named P24_TITRE. When he create a new record in the form, I want to compare the value typed for that item with the column TITRE in the table AD_TACHE. If a line of the table contains the same value in the column TITRE, then an alert message would appear warning that the value is the same in the table.

Best regards.
