Thread: Linking question

Hi,

I want to make use of some contrib/dblink functions inside my user
defined functions, e.g. I would like to be able to call dblink_record()
from my user defined code in this way:

dblink_record("param1","param2");

Is this possible?

I would like to avoid:

1) inserting all the dblink code in my *.c file. This would not be a
very clean way.

2) executing: "select dblink(...)"

Any ideas on how to link my user-defined function with functions in
another file? This is maybe a C question but I'm not good at it at all!


Thanks in advance!!

Why do you want to avoid "select dblink(...)"?  It would be easy
to handle such a query with the Server Programming Interface (SPI):

http://www.postgresql.org/docs/7.4/static/spi.html

If you don't use SPI then you're probably going to have to duplicate
some of the magic it performs.  This seems needless, especially
since you admit that you're not good at C.
