How to process data in the past based from data in the present

Question

hello guys,
i have a problem in my labview programs. how to process data in the past based from data in the present ?
i have a formula self-organizing maps
this formula is looking for D1, D1 is neuron index that will be searched for the smallest value.and the result are D1=2 ,D2=5, D3=17 from calculating with formula  .it means the smallest value is 2, "2" from weight [2 2] in file attached.
and then it will be in other formula
it mean [2 2] + 0.5 ( [1 1]-[2 2] ) = [1.5 1.5]
and the weight will be  [1.5 2 2 ] in matrix

Hi Ronny Hanks,
Moving your records from internal table into the database table depends upon various scenarios :-
1. If you use INSERT statement.
INSERT <database_table> FROM TABLE <internal_table>.
But in this case, you need to make sure that you don't have any duplicate entries in your internal table that violates data entry into database table, else you will get a dump.
INSERT <database_table> FROM TABLE <internal_table> ACCEPTING DUPLICATE KEYS.
In this case, you are forcefully inserting duplicate records into your database table which may lead to data redundancy in your database table.
2. If you use UPDATE statement.
UPDATE <database_table> FROM TABLE <internal_table>.
This will update the existing records in your database table from the internal table.
3. If you use MODIFY statement.
MODIFY <database_table> FROM TABLE <internal_table>.
This statement works both in combination of INSERT & UPDATE statements.
Existing records (in database table) will be eventually updated/modified and new records (not in database table currently) will be successfully inserted into the database table.
Hope this solves your problem.
Thanks & Regards.
