I don't normally have web access. I'd much prefer the build instructions include how to build the documentation.

I've not had anyone explain what it means yet. 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).
