As I try to compile my code, I get this error:
1>Main.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) public: class std::basic_string,class std::allocator > const & __cdecl sql::SQLException::getSQLState(void)const " (__imp_?getSQLState@SQLException@sql@@QBAABV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@XZ) referenced in function __catch$57778
Now there are a couple more, but I think solving this one, will solve the others as well.
I'm trying to get a SQL connection from an WinCe 6.0 Device to a Server.
First thoughts: Do I need to import the .dll
/.lib
files to my WinCe device?
Here's my code:
include <windows.h>
include <ScanCApi.h>
include <iostream>
include <cppconn/driver.h>
include <cppconn/exception.h>
include <cppconn/resultset.h>
include <cppconn/statement.h>
include <stdlib.h>
int wmain() {
try {
sql::Driver *driver;
sql::Connection *con;
sql::Statement *stmt;
sql::ResultSet *res;
/* Create a connection */
driver = get_driver_instance();
con = driver->connect("tcp://127.0.0.1:3306", "root", "root");
/* Connect to the MySQL test database */
con->setSchema("test");
stmt = con->createStatement();
res = stmt->executeQuery("SELECT 'Hello World!' AS _message");
while (res->next()) {
std::cout << "\t... MySQL replies: ";
/* Access column data by alias or column name */
std::cout << res->getString("_message") << std::endl;
std::cout << "\t... MySQL says it again: ";
/* Access column data by numeric offset, 1 is the first column */
std::cout << res->getString(1) << std::endl;
}
delete res;
delete stmt;
delete con;
} catch (sql::SQLException &e) {
std::cout << "# ERR: SQLException in " << __FILE__;
std::cout << "(" << __FUNCTION__ << ") on line " << __LINE__ <<
std::endl;
std::cout << "# ERR: " << e.what();
std::cout << " (MySQL error code: " << e.getErrorCode();
std::cout << ", SQLState: " << e.getSQLState() << " )" << std::endl;
}
return 0;
}
