RE: BUG #15176: ecpg generation error

Hello Michael,

sorry how I wrote my message. English is not my first language. 
I didn't try to offend or blame anybody. I am happy, that there are volunteers like you
and I respect all who work at postgresql.

I compiled again the generated file in C mode and it worked. So thank you for this hint. 
It was not clear for me, that scope works differently in C and C++ and 
scope does not really exist under C.

I would appreciate a small change. If ecpg would use sizeof("variable") instead of sizeof("type") the
generated code compile also with a C++-compiler. Is it possible to extend ecpg that way?
The name of the variable is already used in the same line to describe the input or output value 
in ECPGdo command.

Cheers,
Uwe


An example:

int main()
{
  EXEC SQL BEGIN DECLARE SECTION;
  struct HostVar_t
  {
    int i;
    VARCHAR name[128];
  };

  struct HostVar_t hostvar;

  EXEC SQL END DECLARE SECTION;


  unsigned long long sz;

  /* sizeof used by ecpg in ECPGdo */
  sz =  sizeof(struct varchar_1);

  /* change, compiles as C and C++ */
  sz =  sizeof(hostvar.name);


  EXEC SQL INSERT INTO names_ta(col_i,col_name)
    VALUES(
      :hostvar.i,
      :hostvar.name
    );

  return 0;
}

/* generated code by ecpg

  { ECPGdo(__LINE__, 0, 1, NULL, 0, ECPGst_normal, "insert into names_ta ( col_i , col_name ) values ( $1  , $2  )", 
    ECPGt_int,&(hostvar.i),(long)1,(long)1,sizeof(int), 
    ECPGt_NO_INDICATOR, NULL , 0L, 0L, 0L, 
    ECPGt_varchar,&(hostvar.name),(long)128,(long)1,sizeof(struct varchar_1), 
    ECPGt_NO_INDICATOR, NULL , 0L, 0L, 0L, ECPGt_EOIT, ECPGt_EORT);}
