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 copytestecho 'CREATE TABLE copytest (f1 INTEGER, f2 INTEGER);' psql copytestecho 'CREATE UNIQUE INDEX
copytest_idxON copytest USING BTREE (f1, f2);' psql copytestecpg copy.pgcgcc 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 12 23 34 45 56 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:
