Обсуждение: SQLCODE==-209
I'm using 7.2devel from CVS, and as I've already reported, the documentation doesn't build.
Consequently I'm forced to rely on documentation for 7.1.2/3 which does not mention -209, at least in the ecpg
documentationI'm looking at,
Nore does it appear in the DB2 documentation I'm using as second recourse.
The error text doesn't mean anything to me either:
Search name(/var/share/pgtest/testdata)
Error in statement 'check filename':
sqlcaid(SQLCA ) sqlabc(140) sqlcode(-209) msg(NULL value without indicator in line 121.)
sqlerrp(NOT SET ) OID(%) NROWS(%)
sqlwarn() sqlext()
sql error NULL value without indicator in line 121.
pgtest@possum c$
Here is the relevant code:
exec sql begin declare section;
char *name = fileName;
int i_filesize;
int i_records = transactionRecords;
exec sql end declare section;
struct stat fileinfo;
if (-1 == stat(name,&fileinfo))
{
fprintf(stderr, "Error checking file info for %s: %s\n",
name, strerror(errno));
}
i_filesize=fileinfo.st_size;
printf("name(%s), size(%d) records(%d)\n",name, i_filesize, i_records);
exec sql insert into tsj0601_loaded_files
(name, filesize, records)
values (
:name,
:i_filesize,
:i_records
);
What I hope for is
a) An explanation as to what's wrong
b) Someone to ensure that it's documented, or correct the code if it should be some other number.

Sorry all. There was a certain amount of nonsence in my previous posting on this topic. The failing sql command is an fact a select into. It fails when trying to retrieve a null value. The insert worked (I can retrieve the record if I don't ask for the null field, so evidently the insert code is correct. -209 is generated by ecpg. I still don't know what "indicator" means though. If I can reasonably be expected to understand the term, there still remains the bug that -209 is undocumented.

I've resorted to examining source code (while it might be the utimate documentation,it's not ideal). I've found several places it can arise, but I still have no idea what the error is. The key seems to be the meaning of the technical term "indicator." On a related matter, (I know it's related because it comes from the code which fails with this error), I think the code generatedby ecpg is wrong: /* exec sql begin declare section */ #line 134 "yahoo.load.pgc" char * name = fileName ; #line 135 "yahoo.load.pgc" int i_filesize ; #line 136 "yahoo.load.pgc" int i_records = transactionRecords ; /* exec sql end declare section */ #line 137 "yahoo.load.pgc" struct stat fileinfo; if (-1 == stat(name,&fileinfo)) { fprintf(stderr, "Error checking file info for %s: %s\n", name, strerror(errno)); } i_filesize=fileinfo.st_size; printf("name(%s), size(%d) records(%d)\n",name, i_filesize, i_records); { ECPGdo(__LINE__, NULL, "insert into tsj0601_loaded_files ( name , filesize , records ) values ( ? , ? , ? )", ECPGt_char,&(name),0L,1L,1*sizeof(char), <---- whoops ECPGt_NO_INDICATOR, NULL , 0L, 0L, 0L, ECPGt_int,&(i_filesize),1L,1L,sizeof(int), ECPGt_NO_INDICATOR, NULL , 0L, 0L, 0L, ECPGt_int,&(i_records),1L,1L,sizeof(int), ECPGt_NO_INDICATOR, NULL , 0L, 0L, 0L, ECPGt_EOIT, ECPGt_EORT); #line 152 "yahoo.load.pgc" I think this is not going to pick up the string *name. Either ecpg should reject this, or generate something like ECPGt_char,(name),0L,1L,1*strlen(name)) but then I'm not much of a C programmer. I'm going to assume that my definition of name offends ecpg and gives rise to the error -209, and try to work round it (Ihave another insert working).
I have added documentation for code 209. Looks like there are other undocumented ones.

I can easily document them all if it would help people.
