Hi,
In pgsql
I'm removing charaters from a String which should be numbers.
I then want to make calculations on these numbers (calculate the ISBN
number).
Do I have to cast the char into int's before I can do the calulations.
Also I looked in the User manual but could not find the modulo function
where is it ?
tx,
Thomas,
