Обсуждение: Embedded SQL in 'C' (cursors)

Does anyone know how to open a cursor for 'C" ..?

I have checked the previous postings but cannot locate the proper syntax

here is a snipit :

void ShowTable_type(){
  EXEC SQL BEGIN DECLARE SECTION;
  char *Atid; // variables to retrieve the table info
  char *Adesc;
  EXEC SQL END DECLARE SECTION;
  EXEC SQL CONNECT 'nathan';
  EXEC SQL DECLARE lets_get_tid CURSOR FOR
    SELECT type.tid;
  printf("Choose the TID to delete\n\n<TID> \n");
  do{
    EXEC SQL OPEN lets_get_tid;

     EXEC SQL FETCH lets_get_tid INTO  //line 255
      :Atid;

    printf("%s",Atid);
  }while(SQLCODE != SQLEND);
  EXEC SQL CLOSE lets_get_tid;
}

What am  I doing wrong ..? here what happens when I rund ecpg :

ecpg  4sql.c -o 4comp.c
4sql.c:124: parse error
make: *** [sql] Error 255

Please if anyone has any ideas please let me know.

Thank you

Nathan

If you download the source code for postgresql there are test programs
located in the src/interfaces/ecpg/test directory.  These files are about
the best learning tools I found for ecpg usage.  IIRC There is an example
of cursor usage in one of .pgc files.
