There is multiple way of deleting a record in Sage X3. If we do not delete the record using the index the database must read the full table to find the rows to be deleted. That means deleting the row would be fast but finding would be very slow. ‘DeleteByKey’ instruction deletes a record at a given key after checking for edit conflicts. It compares the UpdTick value of the [F] record with the UpdTick of the corresponding database record and it deletes the database record only if the two ticks are equal.
Syntax:
DeleteByKey [ABV]KEY = KEY_VALUE
DeleteByKey KEY = KEY_VALUE
• ABV is the abbreviation of a table. It must match a File declaration.
• KEY is the description of the key used to access to the table. It can have one of the following syntax:
o KEYVAR where KEYVAR is the code of a key declared in the dictionary or the name of a temporary index from an Order by Key clause.
o KEYVAR(INDEX) where INDEX is a numeric expression giving the number of key parts considered for the condition.
• KEY_VALUE is a list of expressions separated by semicolons.
All these elements are optional.
