Write to database

[rhei]

Hello.

i have this vi and i want to write in a MySql database.

It works to write in XAMPP database but i want to write only a value every time the program runs. Everytime i start the vi overwrite the previous value in the database.

To be clear: let's say first run i write: A 3, next run i write B 4.

i want both values to be stored in the database not only the last one.

Thank you.

Are you sure it is overwriting the previous value?  Your SQL statement only says to insert ("A", "3").  There is nothing about ("B", "4") in your code.  Also, if one of your dB columns only allows unique values, when you try to insert the same value again, the transaction will fail.  Do you get any errors?

Now i can do this. The boolean value from function "Create data base" must be false. it's a overwrite option.

Thank you.
