I was already thinking somemonths ago in a change (and patch proposal).
The problem is, that the generated C-code for an ESQL/C statement looks
today like this:
{ ECPGdo(__LINE__, 0, 0, NULL, 0, ECPGst_normal, "insert into swd_daten ( katkey , aktion , reserv , id , ansetzung , nettodaten ) values ( $1 , $2 , $3 , $4 , $5 , $6 )",
ECPGt_long,&(new_value),(long)1,(long)1,sizeof(long),
ECPGt_NO_INDICATOR, NULL , 0L, 0L, 0L,
ECPGt_short,&(hrec_swd_daten.aktion),(long)1,(long)1,sizeof(short),
ECPGt_NO_INDICATOR, NULL , 0L, 0L, 0L,
ECPGt_char,(hrec_swd_daten.reserv),(long)2,(long)1,(2)*sizeof(char),
ECPGt_NO_INDICATOR, NULL , 0L, 0L, 0L,
...
ECPGt_char,(hrec_swd_daten.nettodaten),(long)SWD_DATEN_BUF_MAX,(long)1,(SWD_DATEN_BUF_MAX)*sizeof(char),
ECPGt_NO_INDICATOR, NULL , 0L, 0L, 0L, ECPGt_EOIT, ECPGt_EORT);
#line 1745 "swd_daten.pgc"
if (sqlca.sqlcode == ECPG_NOT_FOUND) posSqlNotFound ( );
#line 1745 "swd_daten.pgc"
if (sqlca.sqlwarn[0] == 'W') posSqlWarning ( );
#line 1745 "swd_daten.pgc"
if (sqlca.sqlcode < 0) posSqlError ( );}
and should be expanded to:
{ ECPGdo(__LINE__, __FILE__, 0, 0, NULL, 0, ECPGst_normal, "insert ...
as the first argument to ECPGdo() is of type int we can not do a hack
like "__LINE__:"__FILE__ (i.e. concatenating line number and filename
into one string. We have to change the call interface function ECPGdo()
and add a string argument. This would make fail all older compiled
applications when the new shared lib having this call is installed.
Here I'm stuck with the idea.
