Обсуждение: Porting embedded SQL from Oracle to Postgres

I am getting an error when attempting to compile using ecpg.

ERROR: syntax error at or near "TYPE"

This code was originally written for Oracle using Pro*/C

from header:

#define RAW_BUFFER_SIZE 524287
typedef struct {   long len;   char buffer[RAW_BUFFER_SIZE];
} internalCompiledData_t;

from .pgc :

EXEC SQL TYPE internalCompiledData_t is LONG VARRAW(RAW_BUFFER_SIZE);

static internalCompiledData_t compiledData;



It appears that the syntax EXEC SQL TYPE .. is ... ; is Oracle specific, is 
there a matching syntax for ecpg?
Or possibly a different way to achieve this datatype equivalencing?

Thanks in advance.
Daniel.

ECPG appears to have at least some support for EXEC SQL TYPE: I see
code to handle it in preproc/preproc.y and some of the test programs
use it.  I haven't used it myself; maybe the programs in the source
code under src/interfaces/ecpg/test will provide helpful examples.

Just trying precompiling this statement gives:

t.pgc:1: ERROR: syntax error at or near "VARRAW"

And this is the expected result as ECPG does not know the VARRAW
datatype. I would be interested to implement this however if I find the
time.

Could you send me a file where ecpg does not accept the TYPE command? It
should be available as long as you use variable types ecpg recognizes.
