Hello,
I habve problems switching databases inside a program This small example gives
an segmentation fault when switching from en existing connection tom SQLite3:
#include <iostream>
#include <string.h>
#include <tntdb/connection.h>
#include <tntdb/connect.h>
#include <tntdb/statement.h>
int main( int argc, char **argv) {
std::string line;
const char* cp;
tntdb::Connection conn;
tntdb::Statement st;
for( int i = 1;; i++) {
cp = ( i % 2) ? "sqlite:testdb_2.db" : "postgresql:dbname=test2";
std::cout << "connecting to " << cp << std::endl;
conn = tntdb::connect( cp);
std::cout << "going to prepare statement" << std::endl;
st = conn.prepare( "UPDATE y SET x = x + 1");
std::cout << "going to execute statement" << std::endl;
st.execute();
std::cout << "FINISHED" << std::endl;
std::getline( std::cin, line);
if( line[ 0] == 'q')
break;
}
}
Output:
========================
connecting to sqlite:testdb_2.db
going to prepare statement
going to execute statement
FINISHED
connecting to postgresql:dbname=test2
going to prepare statement
going to execute statement
FINISHED
connecting to sqlite:testdb_2.db
going to prepare statement
/bin/bash: Zeile 1: 20902 Speicherzugriffsfehler xx
Thanks for any help
Michael
