Обсуждение: ecpg help

Hi,
I am trying to use preprocessor directives inside the declare statements but
its giving me compile time errors.
What i am do is something like this

EXEC SQL BEGIN DECLARE SECTION;
char myvar[NUM];
EXEC SQL END DECLARE SECTION;

#define NUM 20 is present in one of the include files.

Please help.
Vikas.

Please use "EXEC SQL DEFINE NUM 20" to define NUM for ECPG. ECPG does
not parse CPP directives.

Try this:

  EXEC SQL DEFINE NUM 20
  EXEC SQL BEGIN DECLARE SECTION;
  char myvar[NUM];
  EXEC SQL END DECLARE SECTION;
