int main()

EXEC SQL INCLUDE SQLCA;
EXEC SQL BEGIN DECLARE SECTION;

char cUserName[30];
char cPassword[30];
char cDBName[30];

EXEC SQL END DECLARE SECTION;
memset( cUserName, 0x00, sizeof( cUserName ) );

memset( cPassword, 0x00, sizeof(cPassword ) );
memset( cDBName, 0x00, sizeof( cDBName ) );

strncpy( cUserName, "informix", 29 );
strncpy( cPassword, "123456", 29 );
strncpy( cDBName, "db", 29 );

EXEC SQL CONNECT TO :cDBName user:cUserName using:cPassword;
if( sqlca.sqlcode == 0 )
{
printf( "%s", " connect successful !");

}
else
{
printf( "%s", " connect error !!" );
}
return 0;
}

ykt> esql MyConnectDB.ec 后生成的 MyConnectDB.c 与 MyConnectDB.o 文件,

请问: 在sco unix 下 用informix环境下,
如何才能让使提示语句: connect successful ! 显示出来???????
或者说: connect error !!" 显示出来也可以??




[解决办法]
esql -o MyConnectDB MyConnectDB.o
你刚刚编译成目标文件，还没连接成可执行程序呢
