Hi,

how can I create a updatescript hat do SQL-Updates with values that are
stored in variables.

For example

1. Do a SELECT-Command and write 2 fieldentry into a variable
2. calculate the values and write the new value into a new variable
3. Do a UPDATE-Command and use the variable with the new value.

Regards,
Ruprecht
