Bug reference: 4955
Logged by: Heiko Folkerts
Email address: heiko.folkerts@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 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 .

ECPGt_varchar,&(synonymstring),(long)500,(long)1,sizeof(struct

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.
