Bug reference: 4955
Logged by: Heiko Folkerts
Email address: heiko.folke...@david-bs.de
PostgreSQL version: 8.4
Operating system: Windows XP
Description: ECPG produces incomplete code
Details:
When compiling the following code with ecpg the result is missing some of
the embedded SQL code:
source in a pgc file:
EXEC SQL BEGIN DECLARE SECTION;
VARCHAR synonymstring[500];
long ID;
char* keywordstring;
EXEC SQL END DECLARE SECTION;
QByteArray buf = Keyword.getKeyword().toUtf8();
keywordstring = buf.data();
ID = Keyword.getLanguageID().getID();
EXEC SQL DECLARE synonymcursor CURSOR FOR SELECT synonym FROM
modelisar_data.tfsssynonym s, modelisar_data.tfsskeyword k WHERE k.id =
s.original_id AND k.keyword = :keywordstring AND k.catalog_id = :ID AND
synonym IS NOT NULL;
int a;
EXEC SQL OPEN synonymcursor;
int b;
EXEC SQL WHENEVER SQLWARNING SQLPRINT;
int c;
EXEC SQL WHENEVER NOT FOUND DO BREAK;
while(true)
{
EXEC SQL FETCH NEXT FROM synonymcursor INTO
:synonymstring;
Result in C-File:
/* exec sql begin declare section */
#line 65 "../../repository/TSSDB/TSSDBPGAccessor.pgc"
struct varchar_synonymstring_65 { int len; char arr[ 500 ]; }
synonymstring ;
#line 66 "../../repository/TSSDB/TSSDBPGAccessor.pgc"
long ID ;
#line 67 "../../repository/TSSDB/TSSDBPGAccessor.pgc"
char * keywordstring ;
/* exec sql end declare section */
#line 68 "../../repository/TSSDB/TSSDBPGAccessor.pgc"
QByteArray buf = Keyword.getKeyword().toUtf8();
keywordstring = buf.data();
ID = Keyword.getLanguageID().getID();
/* declare synonymcursor cursor for select synonym from modelisar_data .
tfsssynonym s , modelisar_data . tfsskeyword k where k . id = s .
original_id and k . keyword = $1 and k . catalog_id = $2 and synonym is
not null */
#line 72 "../../repository/TSSDB/TSSDBPGAccessor.pgc"
int a;
{ ECPGdo(__LINE__, 0, 1, NULL, 0, ECPGst_normal, "declare synonymcursor
cursor for select synonym from modelisar_data . tfsssynonym s ,
modelisar_data . tfsskeyword k where k . id = s . original_id and k .
keyword = $1 and k . catalog_id = $2 and synonym is not null",
ECPGt_char,&(keywordstring),(long)0,(long)1,(1)*sizeof(char),
ECPGt_NO_INDICATOR, NULL , 0L, 0L, 0L,
ECPGt_long,&(ID),(long)1,(long)1,sizeof(long),
ECPGt_NO_INDICATOR, NULL , 0L, 0L, 0L, ECPGt_EOIT, ECPGt_EORT);}
#line 74 "../../repository/TSSDB/TSSDBPGAccessor.pgc"
int b;
/* exec sql whenever sql_warning sqlprint ; */
#line 76 "../../repository/TSSDB/TSSDBPGAccessor.pgc"
int c;
/* exec sql whenever not found break ; */
#line 78 "../../repository/TSSDB/TSSDBPGAccessor.pgc"
while(true)
{
{ ECPGdo(__LINE__, 0, 1, NULL, 0,
ECPGst_normal, "fetch next from
synonymcursor", ECPGt_EOIT,
ECPGt_varchar,&(synonymstring),(long)500,(long)1,sizeof(struct
varchar_synonymstring_65),
ECPGt_NO_INDICATOR, NULL , 0L, 0L, 0L, ECPGt_EORT);
#line 81 "../../repository/TSSDB/TSSDBPGAccessor.pgc"
if (sqlca.sqlcode == ECPG_NOT_FOUND) break;
#line 81 "../../repository/TSSDB/TSSDBPGAccessor.pgc"
if (sqlca.sqlwarn[0] == 'W') sqlprint();}
#line 81 "../../repository/TSSDB/TSSDBPGAccessor.pgc"
It seems that the open command for the cursor is not present. The first
fetch passes but with wrong data in the host variables.
