System Configuration
---------------------
Architecture (example: Intel Pentium) : Intel Pentium
Operating System (example: Linux 2.0.26 ELF) : Linux 2.2.16-22, RedHat 7.0
PostgreSQL version (example: PostgreSQL-7.1.3): PostgreSQL-7.1.3
Compiler used (example: gcc 2.95.2) : RPM
Please enter a FULL description of your problem:
------------------------------------------------
'TRUNCATE TABLE' in embedded SQL results in the table being dropped!
Please describe a way to repeat the problem. Please try to provide a
concise reproducible example, if at all possible:
----------------------------------------------------------------------
Execute the following commands:
createdb copytest
echo 'CREATE TABLE copytest (f1 INTEGER, f2 INTEGER);' psql copytest
echo 'CREATE UNIQUE INDEX copytest_idx ON copytest USING BTREE (f1, f2);' psql copytest
ecpg copy.pgc
gcc copy.c -I /usr/include/pgsql -lecpg -lpq
./a.out
Which will result in the following output from 'a.out':
Error -400: 'ERROR: Relation 'copytest' does not exist' in line 17.
given the following source 'copytest.pgc':
#include <stdlib.h>
#include <time.h>
#include <sys/time.h>
#include <unistd.h>
EXEC SQL INCLUDE sqlca;
int main(int argc, char **argv)
{
EXEC SQL CONNECT TO copytest;
if( sqlca.sqlcode != 0 )
return( 1 );
EXEC SQL TRUNCATE TABLE copytest;
if( sqlca.sqlcode < 0 )
return( 1 );
EXEC SQL COPY copytest FROM '/tmp/copytest';
if( sqlca.sqlcode < 0 )
{
printf("Error %ld: %s\n", sqlca.sqlcode, sqlca.sqlerrm.sqlerrmc);
return( 1 );
}
EXEC SQL COMMIT;
EXEC SQL DISCONNECT;
return( 0 );
}
and the following '/tmp/copytest' (not used):
1 1
2 2
3 3
4 4
5 5
6 6
If you add an 'EXEC SQL COMMIT' after the TRUNCATE and then do a '\d'
in psql the table is not shown - it has been dropped.
If you know how this problem might be fixed, list the solution below:
