Hi there,
I'm looking for an alternative to statically sized character arrays
within ECPG.
E.g. exec sql select relname into :VAR from pg_classes;
It should (!) be possible to obtain this by using pointers which are
initialized to NULL.
It is possible for integer *var=0; reading an arbitrary number of integers into a malloced array
and char *var=0; reading one arbitrary length string into a malloced character
array
Works perfectly.
But ecpg does not accept char **var=0;
Is there any way to specify arbitrary strings of any length ?
The code (execute.c:435) has also support for varchar - but how to
declare such a variable length varchar?
And the code (execute.c:432) multiplies the number of tuples with the
longest string. But how to use this code in real life?
Looks like dead code to me (hopefully I'm wrong)
Yours Christof
PS: I'm willing to implement char**
(allocate tuples*sizeof(char*) + sum(length(tuple[n])+1) bytes,fill the array with pointers,fill the space behind the
arraywith the actual data.This means just one free get's it all.But this code cannot be portable!)
