Hello,
I am learning to programm triggers in C by using the examples and the
programmer's manual but it's a steep learning curve for a mere perl
programmer ;-)
What I am trying to do for instance is:
- read a ::text colum with SPI_getbinval(),
- convert it to a char*,
- modify it,
- convert it back to a Datum,
- reinsert it into the tuple through SPI_modifytuple,
The conversions involve some pointer magic and casting that I really
don't grasp.
Also I am trying to read a timestamp with SPI_getbinval and get the
number of seconds contained. Using DatumGetInt32 doens't seem to do it.
Thanks in advance for your insight, cheers,
